  13 <div class="section" id="id1">
  14 <h1><a name="id1">2.6.0.1</a></h1>
  15 <p>Added wx.BrushFromBitmap to create a stippled brush in a single step.
  16 Also added missing brysh style flags: wx.STIPPLE_MASK
  17 wx.STIPPLE_MASK_OPAQUE.</p>
  18 <p>wxMSW: Fix for default control colours when the system text fg colour
  19 is not black.</p>
  20 <p>wxGTK: Patch #1171754, It is now possible to have a menu item that
  21 both has an icon and is a submenu.</p>
  22 <p>wxMSW: Patch #1197009, better refreshes when windows are moved and
  23 resized.</p>
  24 <p>wxMSW: Patch #1197468.  Keeps track of pending size/position changes
  25 in case there is more than one adjustment for a window in a single
  26 DeferWindowPos set, then the pending values can be used for defaults
  27 instead of current values.</p>
  28 <p>Fixed the typemap that converts a Python list of strings to a
  29 wxArrayString so it uses the wxPython default encoding.</p>
  30 <p>Several docstrings added and updated.  Lots more to go.</p>
  31 <p>wxMac: Strings added to the clipboard or used in DnD no longer have an
  32 extra null character at the end.</p>
  33 <p>Added wx.GetXDisplay that returns a raw swigified pointer for the X11
  34 Display, or None for the non-X11 platforms.</p>
  35 <p>wxMenu: Don't send an event when selecting an already selected radio
  36 item.</p>
  37 <p>Added wx.LaunchDefaultBrowser.</p>
  38 <p>wxMSW: Fixed erroneous selection of content in wx.ComboBox when within
  39 a wx.StaticBox.</p>
  40 <p>wxMSW: Fixed alpha blitting to take into account source position.</p>
  41 <p>Ensure that Python is still in an initialized state before doing any
  42 locking or unlocking in wxPyBeginBlockThreads and wxPyEndBlockThreads
  43 as these can be triggered after Python has been finalized in embedding
  44 situations.</p>
  45 <p>Added alternate constructors for wx.Font: wx.FontFromPixelSize,
  46 wx.FFont, wx.FFontFromPixelSize.  See the docstrings or new api docs
  47 for details.</p>
  48 <p>Added wx.lib.hyperlink from Andrea Gavana.  It is a control like
  49 static text that acts like a hyper-link, launching the system's
  50 default browser in response to the clicks.</p>
  51 <p>Added an optional parameter to wxversion.select that allows you to
  52 specify that the extra components specified in the version string are
  53 required.  For example, if you ask for &quot;2.6-unicode&quot; but only the ansi
  54 version is installed then by default the ansi version will be selected
  55 as it considered close enough since the version numbers match.  If you
  56 want to force the options to be required then you can just add a True
  57 parameter, like this:</p>
  58 <pre class="literal-block">
  59 import wxversion
  60 wxversion.select(&quot;2.6-unicode&quot;, True)
  61 import wx
  62 </pre>
  63 <p>Tweaked wx.lib.buttons such that flat buttons (e.g. have no bevel and
  64 a wx.BORDER_NONE style flag) paint themed backgrounds if there are
  65 transparent areas and the parent is displaying a theme.</p>
  66 <p>wxMSW:  Fix for wrong sash colour of wx.SplitterWindow in the silver
  67 theme on XP.</p>
  68 <p>Added a wx.xrc.XmlResourceHandler for the Ticker class.  See
  69 wx/lib/ticker_xrc.py</p>
  70 <p>wxSTC: Fixed CmdKeyAssign key bindings for Ctrl-Backspace.</p>
  71 <p>wxMSW: Fixed a bug in wx.TextCtrl where all the lines were being used
  72 to calculate the best size, instead of using a reasonable limit.</p>
  73 </div>
  74 <div class="section" id="id2">
  75 <h1><a name="id2">2.6.0.0</a></h1>
  76 <ul class="simple">
  77 <li>26-Apr-2005</li>
  78 </ul>
  79 <p>wxMSW: Fixed wx.TransientPopupWindow (and therefore wx.TipWindow) to
  80 auto-dismiss when the mouse is clicked outside of the popup like it is
  81 supposed to.</p>
  82 <p>wxMSW: Fixed bug #1167891 wx.Notebook display problem with wx.NB_MULTILINE.</p>
  83 <p>wxMSW: Fixed bad cliping of hidden windows inside of wx.StaticBox.</p>
  84 <p>wxGTK:  The configure flags for selecting GTK+ 1.2.x or 2.x has
  85 changed slightly.  It is now --with-gtk[=VERSION] where VERSION is
  86 either '1', '2' or 'any'.  The default is '2'.</p>
  87 <p>wx.stc.StyledTextCtrl: Added the following methods for alternate ways
  88 to set and fetch text from the document buffer.  They work similarly
  89 to the existing methods of the same name, except that they don't go
  90 through the same string/unicode &lt;--&gt; wxString conversions.  The &quot;Raw&quot;
  91 methods will do no conversions at all and in a unicode build of
  92 wxPython the strings will be in the utf-8 encoding and in an ansi
  93 build no assumption is made about the encoding.  The &quot;UTF8&quot; functions
  94 will attempt to always get/set utf-8 text, which it will always be
  95 able to do in a unicode build, and in an ansi build it will depend on
  96 the content of the utf-8 used being compatible with the current
  97 encoding, (you'll get an exception otherwise.)</p>

 135 <p>wx.stc.StyledTextCtrl:  Added the StyleSetFontEncoding(style, enc)
 136 method that allows you to set the encoding to be used by the font for
 137 a particular style.</p>
 138 <p>wxMac: Fixed wx.ComboBox to forward the EVT_CHAR, EVT_KEY_DOWN,
 139 EVT_KEY_UP and EVT_TEXT events from its embedded text control.</p>
 140 <p>wxMac: Corrected refresh bugs in wxGrid.</p>
 141 <dl class="docutils">
 142 <dt>XRCed: Updated to version 0.1.5.</dt>
 143 <dd><ul class="first last simple">
 144 <li>Added wxWizard, wxWizardPageSimple (only from pull-down menu).</li>
 145 <li>Hide command for test window.</li>

 153 <h1><a name="id3">2.5.5.1</a></h1>
 154 <ul class="simple">
 155 <li>8-Apr-2005</li>
 156 </ul>
 157 <p>wxMSW: Fixed bug #1022383, 'several ComboBoxes appear selected'</p>
 158 <p>wx.grid.Grid: Fixed bug #1163384.  Moved the code that handles
 159 activating the cell editors to a EVT_CHAR event handler.  This is done
 160 so the character inserted into the editor will be the &quot;cooked&quot; char
 161 value (including accented or composed keys) rather than the raw code
 162 provided by the EVT_KEY_DOWN event.</p>
 163 <p>Added orient parameter to wx.MDIParentFrame.Tile()</p>
 164 <p>wxMSW: wxTextCtrl with wx.TE_RICH2 style now uses RichEdit 4.1 if
 165 available.</p>
 166 <p>Added GetCount, GetCountRGB, and GetCountColour methods to
 167 wx.ImageHistogram.</p>
 168 <p>wxMSW: wx.Window.Refresh changed to explicitly refresh all children as
 169 well as the parent.  Previously it was implicitly done because parents
 170 did not clip their children by default.  Now that they always clip
 171 children then Refresh needed to be fixed to do a recursive refresh.
 172 This also fixes the Freeze/Thaw problems that some people had with
 173 2.5.4.1.</p>
 174 <p>wx.SplitterWindow: Send EVT_SPLITTER_SASH_POS_CHANGED only once after
 175 end of dragging and not after each CHANGING event (modified patch
 176 #1076226)</p>
 177 <p>wx.glcanvas.GLCanvas: applied patch fixing problems with X server
 178 crash when using nVidia cards (patch 1155132)</p>
 179 <dl class="docutils">
 180 <dt>wx.lib.mixins.listctrl: Patches from Toni Brkic:</dt>
 181 <dd><ul class="first last simple">
 182 <li>Bugfix for TextEditMixin when the view can't be scrolled</li>
 183 <li>Enhancement for ListCtrlAutoWidthMixin, allowing it to manage
 184 the width of any column.</li>
 185 </ul>
 186 </dd>
 187 </dl>
 188 <p>wxMac: removal and reusing toolbar tools like the other platforms is
 189 now possible.</p>
 190 <p>wxMac: Correct radio tool selection after calling Realize a 2nd time.</p>
 191 <p>wxMSW: Applied patch #1166587, removes all flicker from wx.StaticBox</p>
 192 <p>Added wx.lib.foldpanelbar, Andrea Gavana's port of Jorgen Bodde's C++
 193 wxFoldPanelBar classes to Python.</p>
 194 <p>wxGTK: Applied patch #1173802, reimplementation of GtkFileChooser
 195 wxFileDialog by Mart Raudsepp.  Note that this new file dialog is only
 196 used on GTK2 &gt;= 2.4.  For earlier GTK2 versions and GTK1 then the
 197 older generic file dialog is used.</p>
 198 <p>wxMSW: fixes to static box borders calculations (finalizes patch
 199 #1166587)</p>
 200 <p>wx.Image: Use Python's buffer interface API for all image data and
 201 alpha Set/Get methods and the ImageFromData* constructors.  They all
 202 still copy the buffer except for SetDataBuffer and SetAlphaBuffer, but
 203 this gives more flexibility on where the data can come from.</p>
 204 <p>Added MDI support to XRC</p>
 205 <p>Added wx.animate module and a demo.  The wx.animate module provides a
 206 control that is able to display an animated GIF file.</p>
 207 <p>wx.lib.plot.py: Applied patch from Werner F. Bruhin that allows either
 208 vertical and/or horizontal gridlines.</p>
 209 <p>wxMSW: Extra space given for top border of wx.StaticBoxSizer so the
 210 upper line is not cliped when there is no label.</p>
 211 <p>wxMSW: Restored old behaviour of wx.StaticBox.SetBackgroundColour only
 212 affecting the label.</p>
 213 <p>wxMSW: Fixed missing EVT_RIGHT_DOWN and EVT_TREE_ITEM_RIGHT_CLICK
 214 events in a wx.TreeCtrl.</p>
 215 <p>Added wx.GetTopLevelWindows() function which returns a copy of the
 216 list of top-level windows that currently exist in the application.</p>
 217 <p>Updated docview library modules and sample apps from the ActiveGrid
 218 folks.</p>
 219 <p>Added the ActiveGrid IDE as a sample application.</p>

 223 <ul class="simple">
 224 <li>16-Mar-2005</li>
 225 </ul>
 226 <p>wx.Sizer Add, Insert, and Prepend functions now return a reference to the
 227 wx.SizerItem that was added to the sizer, and the wx.SizerItem has a
 228 GetRect accessor to give the position of the item on the parent window.</p>
 229 <p>Added wx.Sizer.GetItem method which returns the wx.SizerItem for the given
 230 wx.Window, wx.Sizer or position index.</p>
 231 <p>wxMSW: wx.RadioButtons in the same group no longer have to be
 232 consecutive (there may be intervening controls). Without this fix, an
 233 out-of-sync assert is generated when clicking on a radio button and
 234 then calling GetValue().</p>
 235 <dl class="docutils">
 236 <dt>Some XRC changes:</dt>
 237 <dd><ul class="first last simple">
 238 <li>Added 'icon' property to wxFrame and wxDialog</li>
 239 <li>No longer ignores menu bitmaps on non-MSW platforms</li>
 240 <li>Notebook page bitmaps are now supported</li>
 241 <li>added system colours and fonts support (based on patch #1038207)</li>
 242 </ul>
 243 </dd>
 244 </dl>
 245 <p>wxMSW: fix for [ 1052989 ] TextCtrl.SetBackgroundColour(wx.NullColour)
 246 bug.</p>
 247 <p>Added wx.PasswordEntryDialog analagous to wx.TextEntryDialog, allows
 248 detecting entering an empty string vs. cancel unlike the
 249 wx.GetPasswordFromUser dialog function.</p>
 250 <p>OGL patch from Shane Holloway:</p>
 251 <blockquote>
 252 <p>Two simple problems found in the new python ogl code.  First is
 253 the patch for _canvas.py.  Essentially:</p>
 254 <pre class="literal-block">
 255 dx = abs(dc.LogicalToDeviceX(x - self._firstDragX))
 256 dy = abs(dc.LogicalToDeviceY(y - self._firstDragY))
 257 </pre>
 258 <p>was incorrect because (x,y) and (self._firstDragX,
 259 self._firstDragY) are both already in Logical coordinates.
 260 Therefore the difference between the two is also in logical
 261 coordinates, and the conversion call is an error.  This bug
 262 surfaces when you have OGL on a scrollwin, and you are far from
 263 the origin of the canvas.</p>
 264 <p>The second change in _composit.py basically removes the assumption
 265 that the child is in both self._children and self._divisions.
 266 Causes many problems when it's not.  ;)</p>
 267 </blockquote>
 268 <p>Fixed GetSaveData and SetSaveData in wx.lib.multisash to not depend on
 269 the default way that class objectss are converted to strings.</p>
 270 <p>Fixed problem in StyledTextCtrl.Set[HV]ScrollBar that could leave the
 271 internal scrollbar visible.</p>
 272 <p>Added wx.StandardPaths which provides methods for determining standard
 273 system paths for each platform.</p>
 274 <p>wxMSW: The window background is now only erased by default if the
 275 background colour or background mode has been changed.  This better
 276 allows the default system themed behaviour to show through for
 277 uncustomized windows.  Explicit support added for using the correct
 278 theme texture for wx.Notebook pages and their children.</p>
 279 <p>wx.Image: Added support for alpha channels in interpolated and
 280 non-interpolated image rotation.  Added ConvertAlphaToMask helper
 281 method for turning shades of grey into shades of alpha and a colour.</p>
 282 <p>wxGTK2: Reimplemented DoDrawRotatedText() by way of a rotation of an
 283 alpha blended text bitmap.  It would be better if Pango could draw
 284 directly into an wxImage (as FreeType can,) but that is for later...</p>
 285 <p>Added wrappers and a demo for the wx.MediaCtrl class, which can play
 286 various forms of audio/video media using native codecs install on the
 287 system.  So far it is only implemented for Windows and OSX.</p>
 288 <p>wxGTK: Patch applied for Freeze()/Thaw() for wxTextCtrtl.</p>
 289 <p>Added &quot;gravity&quot; for splitter window (patch 1046105). Gravity is a
 290 floating-point factor between 0.0 and 1.0 which controls position of
 291 sash while resizing the wx.SplitterWindow.  The gravity specifies
 292 how much the left/top window will grow while resizing.</p>
 293 <p>wxMSW: wx.Slider's C++ implementation rewritten to be more
 294 maintainable and hopefully less buggy.  The position of the labels has
 295 also been changed in order to better comply with Microsoft's examples
 296 of how to use the control.</p>
 297 <p>wxMSW:  Fix wx.TreeCtrl to end label editing if the control loses
 298 focus (a slightly modified patch 1084592.)</p>
 299 <p>Added wx.EXEC_NODISABLE flag for wx.Execute, which will prevent all
 300 the app's windows being disabled while a synchronous child process is
 301 running.</p>
 302 <p>wxMSW: Much work to correct painting (or leaving transparent) of
 303 control backgrounds, properly using background themes on XP, etc.</p>
 304 <p>Fixed a circular reference problem with wx.Timer.  It will now
 305 completely cleanup after itself when the last reference to the timer
 306 is removed.  If you were previously using timer.Destroy() to cleanup
 307 your timers it will no longer work.  Instead you should hold a
 308 reference to the timer and then del the reference when you are
 309 finished with the timer.</p>
 310 <p>Updated to 1.3.24 of SWIG.  All of my big patches have been applied to
 311 the main SWIG source tree, but unfortunatly there were also some bugs
 312 added that affected the wxPython build and a few details in my
 313 original patch were changed/removed, so we are still not free of
 314 patches.  A new patch for SWIG is located in the wxPython/SWIG
 315 directory of the wxPython source tree.  SWIG 1.3.24 plus this patch
 316 should be used by anyone who is making custom modifications to
 317 wxPython's .i files, or building their own extension modules or
 318 etc. that need to interact with the wxPython swigged types.  For the
 319 morbidly curious, here are a few more details:</p>
 320 <blockquote>
 321 <ul class="simple">
 322 <li>Since it is now possible easily and simply share the SWIG type
 323 tables across modules I reverted to always using the stock SWIG
 324 runtime instead of my slightly hacked up version of it exported
 325 via the wxPython C API.</li>
 326 <li>The %name directive is now deprecated so I replaced most uses of
 327 it with a custom %Rename macro that uses %rename internally.
 328 These will evetually need to be replaced with a DocDecl macro
 329 when docstrings are added for those items.</li>
 330 <li>The &quot;this&quot; attribute of all SWIGged classes is no longer a
 331 string containing a &quot;swigified pointer&quot;, but rather a custom
 332 built-in type that holds the real C pointer to the object and
 333 the type info.  It can be converted to a string like the old
 334 value using str() or to the long integer value of the pointer
 335 using long().</li>
 336 </ul>
 337 </blockquote>
 338 <p>Added SetDefaultPyEncoding and GetDefaultPyEncoding functions which
 339 will set/get the encoding used by wxPython to convert string or
 340 unicode objects to/from wxString objects.  Previously the default
 341 Python encoding was always used, but unless the user had tweaked their
 342 sitecustomize.py file it is always &quot;ascii&quot;, which would result in
 343 errors if the strings contained character codes &gt;= 128.
 344 SetDefaultPyEncoding will now allow you to control which encoding will
 345 be used to do those conversions.  The default encoding is set to the
 346 value of <cite>locale.getdefaultlocale()[1]</cite> when wxPython is first
 347 imported.  Please see <a class="reference" href="http://www.alanwood.net/demos/charsetdiffs.html">http://www.alanwood.net/demos/charsetdiffs.html</a>
 348 for information on the differences between the common latin/roman
 349 encodings.</p>
 350 <p>Added wxStdDialogButtonSizer, which is a a special sizer that knows
 351 how to order and position standard buttons in order to conform to the
 352 current platform's standards.  You simply need to add each <cite>wx.Button</cite>
 353 to the sizer, and be sure to create the buttons using the standard
 354 ID's.  Then call <cite>Realize</cite> and the sizer will take care of the rest.</p>
 355 <p>wxMSW Toolbar: pass correct tool id (and not always -1) to the
 356 EVT_TOOL_RCLICKED handler</p>
 357 <p>wxGTK: Applied patch for combo box SELECTED events (no longer get
 358 lots of surplus events)</p>
 359 <p>wxGTK: Applied patch for proper menu highlight colour detection in
 360 wx.SystemSettings.</p>
 361 <p>wxGTK: Commited scrollbar patch #1093339 which sends lineup, linedown
 362 events based on intercepting the mouse down events.</p>
 363 <p>wxGTK: Applied patch #1102789 which solved conflicts between wxWidgets
 364 and GTK+'s context menu code.</p>
 365 <p>wxGTK: Applied patch #1100327 for correct feedback from DND actions
 366 (not all actions are allowed).</p>
 367 <p>Fixed memory leak in wxGrid::UpdateAttr[Rows][Or][Cols] (patch 1104355)</p>
 368 <p>For efficiency reasons, text controls no longer set the string for
 369 each text updated event, but rather query for the string value only
 370 when GetString is called from an event handler.</p>
 371 <p>Added wx.SL_INVERSE style which will cause wx.Slider to invert the min
 372 and max ends of the slider.</p>
 373 <p>Several patches applied, such as #1111174, #1110252 and others, that
 374 make the generic wx.TreeCtrl (used on wxGTK and wxMac) be more
 375 conistent with the wxMSW native wx.TreeCtrl.</p>
 376 <dl class="docutils">
 377 <dt>XRCed:</dt>
 378 <dd><ul class="first last simple">
 379 <li>Edit-&gt;Locate command (Ctrl-L) for quick selection of items.
 380 Works with event-handling controls (buttons, text fields) but
 381 not with labels/sizers.</li>
 382 <li>Some improvements: relative paths for files supplied as command-
 383 line argument work correctly, notebook panels are highlighted
 384 better.</li>
 385 </ul>
 386 </dd>
 387 </dl>
 388 <p>wxMac: Fixed a long-standing issue where wxSlider controls with a
 389 hardcoded size would misplace their labels behind the slider control.</p>
 390 <p>wx.HtmlListBox fixed so calling RefreshLine(s) will cause the data for
 391 that line to be refetched from the overridden methods in the derived
 392 class.</p>
 393 <p>The default DoGetBestSize now includes the difference (if any) between
 394 the client size and total size of the window, (such as the size of
 395 borders.)  Code that sets the client size using the best size, or that
 396 added extra space to sizers to compensate for this bug may need to be
 397 changed.</p>
 398 <p>Can suppress themed notebook pages with the wxNB_NOPAGETHEME style or
 399 setting system option msw.notebook.themed-background to 0.</p>
 400 <p>wxSyledTextCtrl updated to use Scintilla 1.62.</p>
 401 <p>Can now set the msw.window.no-clip-children system option to 1 to
 402 eliminate weird refresh behaviour (delays between a window being
 403 erased and repainted, giving a ghostly gradual-redraw effect). May be
 404 a temporary 'fix' until properly fixed before 2.6.</p>
 405 <p>wxMac:  Toolbar is now more native looking with borderless toolbar
 406 buttons.</p>
 407 <p>wxMac: Switched wx.Bitmap to use newer Quartz object types and APIs
 408 internally.  This results in faster display and better alpha support.</p>
 409 <p>Added wx.DatePickerCtrl.</p>
 410 <p>wx.html.HtmlWindow now supports background images.</p>
 411 <p>Added wx.lib.gestures module from Daniel Pozmanter which supports
 412 using Mouse Gestures in an application.</p>
 413 <p>wxGTK2: ENTER and LEAVE mouse events are now sent for multi-line text
 414 controls.</p>
 415 <p>wxMSW:  &quot;Alt&quot; key (VK_MENU) now results in WXK_ALT keyboard event, not
 416 WXK_MENU</p>
 417 <p>Added modules from Peter Yared and Morgan Hua that implement the wx
 418 Doc/View framework in pure Python code.  See wx.lib.docview for the
 419 base implementation and wx.lib.pydocview for Python-specific
 420 extensions.  There are also a couple sample applications located in
 421 samples/docview.</p>
 422 <p>Added GetBitmap, GetIcon to wx.ImageList.</p>
 423 <p>wxGTK wx.Button.SetLabel no longer invalidates/resets the font.</p>
 424 <p>wx.Sizer.AddWindow, AddSizer, AddSpacer and etc. have now been
 425 undeprecated at the request of Riaan Booysen, the Boa Constructor team
 426 lead.  Boa needs them to help keep track of what kind of item is being
 427 managed by the sizer.  They are now just simple compatibility aliases
 428 for Add, and etc.</p>
 429 <p>The old C++ version of the OGL lib is no longer built by default.  Use
 430 the Python version in the wx.lib.ogl package instead.</p>
 431 <p>The wx.iewin module is no longer built by default.  You can use the
 432 wx.lib.iewin version instead.</p>
 433 <p>Fixed wx.BufferedPaintDC for scrolled windows to work whether the
 434 buffer is covering only the client area or the full virtual area of
 435 the scrolled window.  By default it will assume that only the client
 436 area is covered.  This is different than the old behavior so to
 437 indicate that the entire virtual area is covered simply add a
 438 style=wx.BUFFER_VIRTUAL_AREA parameter.</p>
 439 <p>wx.gizmos.TreeListCtrl:  Add support for the EVT_TREE_ITEM_GETTOOLTIP
 440 event.</p>
 441 <p>Added Resize, SetRGBRect, Size, and GetOrFindMaskColour methods to
 442 wx.Image.</p>
 443 <p>Added wx.Rect.IsEmpty</p>

 460 <p>wxMac focus and border refreshes corrected.</p>

 462 <p>wxMac fix for metal appearance on wx.ToolBar.</p>
 463 <p>wx.grid.Grid fix allowing DoGetBestSize to be called before CreateGrid
 464 (which means that a min size doesn't need to be specified.)</p>
 465 <p>wxMac fix for not sending a native click to a control if it is not
 466 enabled (does an enable itself)</p>
 467 <p>Added wx.lib.ogl.DrawnShape, and fixed various little bugs in the new
 468 OGL.</p>
 469 <p>Added support to XRC and XRCed for the 3-state checkbox flags and also
 470 for wx.ToggleButton.  Updated the generic window styles supported by
 471 XRCed.</p>
 472 <p>It is now possible to create &quot;stock&quot; buttons.  Basically this means
 473 that you only have to provide one of the stock IDs (and either an
 474 empty label or a label that matches the stock label) when creating the
 475 button and wxWidgets will choose the stock label to go with it
 476 automatically.  Additionally on the platforms that have a native
 477 concept of a stock button (currently only GTK2) then the native stock
 478 button will be used.  For example, the following will result in a
 479 button with &quot;Cancel&quot; as the label and if run on wxGTK2 then there will
 480 also be an image of a red X:</p>
 481 <pre class="literal-block">
 482 b = wx.Button(parent, wx.ID_CANCEL)
 483 </pre>
 484 <p>Added wx.lib.ticker.Ticker class from Chris Mellon.</p>
 485 <p>Fix some incorrect clipping regions in wxSTC on wxGTK.</p>
 486 <p>Added wrapper for wx.grid.Grid.GetOrCreateCellAttr.</p>
 487 <p>Removed my copy of distutils from the wxPython source tree.  Now that
 488 I am no longer doing builds on Python 2.1 the newest distutils is no
 489 longer needed.  (There is still one small bug in Python 2.2 distutils
 490 on win32, but it is easily worked around.) This sovles the problem of
 491 incorrect builds on some systems where the system installed distutils
 492 has been patched to behave slightly differently, for example SuSE on
 493 x86_64 or Chandler's build.</p>
 494 <p>Updated to SWIG 1.3.22 (plus my patch.)  See wxPython/SWIG/README.txt
 495 in the source tree if you need to use SWIG when building your own copy
 496 of wxPython, or other extension modules that need to integrate with
 497 the wxPython modules.</p>
 498 <p>Added wx.Frame.RequestUserAttention which, if the platform suports it,
 499 will do something (such as flash the task bar item) to suggest to the
 500 user that they should look at that window.</p>
 501 <p>&quot;Fixed&quot; wx.grid.Grid.SetDefaultEditor and SetDefaultRenderer by making
 502 them register the editor or renderer for the &quot;string&quot; data type.</p>
 503 <p>Added depth param to wx.Image.ConvertToBitmap.</p>
 504 <p>Extended the wx.calendar.CalendarCtrl class with methods that get/set
 505 a Python datetime or date object.  (These will only work with Python
 506 2.3+) The methods are PySetDate, PyGetDate, PySetLowerDateLimit,
 507 PySetUpperDateLimit, PySetDateRange, PyGetLowerDateLimit, and
 508 PyGetUpperDateLimit.  Also, CalendarEvent was extended with PySetDate
 509 and PyGetDate methods.</p>
 510 <p>wxMSW: SetBackgroundColour on a wx.Choice or a wx.ComboBox will now
 511 also set the colour of the dropdown.</p>
 512 <p>wxMac: MessageDialog now supports wx.NO_DEFAULT style</p>
 513 <p>wxMSW: added AssociateHandle and DissociateHandle to wx.Window</p>
 514 <p>wxMac: fix for toolbar tooltips</p>
 515 <p>wx.Sizer.Show (and Hide) now take an optional parameter specifying if
 516 the item to be shown should be searched for recursivly in subsizers,
 517 and return a boolean value indicating if the item was found.</p>
 518 <p>wxMSW: fixed MaximizeEvent generation in wx.Frame</p>

 520 <p>Smoother time estimation updates in wx.ProgressDialog (patch 992813)</p>
 521 <p>Made wx.Listbook events more consistent with wx.Notebook ones (patch
 522 1001271)</p>
 523 <p>Fixed rounding errors in variable status bar panes widths computation
 524 (patch 1030021)</p>
 525 <p>Added possibility to specify printer bin (patch 910272)</p>
 526 <p>wxMSW: fixed wx.ListCtrl's SetWindowStyleFlag() to not remove
 527 WS_VISIBLE; also refresh the control automatically (closes bug
 528 1019440)</p>
 529 <p>Added wx.Choicebook, yet another notebook-like control.</p>
 530 <p>wxMSW: Make radiobutton tab behaviour the same on MSW as in standard
 531 MSW app, i.e. tab into the activated, not necessarily the first radio
 532 button.</p>
 533 <p>Added limited support for wxEventLoop (you can't derive from a
 534 wx.PyEventLoop version yet...)  Updated and moved the sample showing
 535 how to replace the MainLoop to samples/mainloop/mainloop.py.</p>
 536 <p>The C++ xrc lib has been moved out of contrib and into the core, so it
 537 is always built by default.  wxPython's build has also changed
 538 accordingly and will build the xrc module as part of the core set of
 539 modules built by default.  If you were axplicitly using BUILD_XRC then
 540 it will no longer be recognized as a build option, otherwise you
 541 should notice no difference.</p>
 542 <p>wxMac: Fixed radio toolbar buttons to correctly untoggle the others
 543 when a new one is selected.</p>
 544 <p>wxMac: Fixed GetLineLength and GetLineText for MLTE text controls</p>
 545 <p>wxMac: wx.TaskBarIcon is implemented by allowing you to change the
 546 app's icon on the Dock and also specifying a menu that should be
 547 merged with the normal dock popup menu.  See the MigrationGuide for
 548 more details and a warning.</p>
 549 <p>Added wx.TopLevelWindow.IsActive() which tells you if the frame or
 550 dialog is or containts the active window with the keyboard focus.</p>
 551 <p>Added ability to create a font based on pixel size rather than point
 552 size via the FontFromPixelSize constructor.</p>
 553 <p>Updated the Scintilla used by StyledTextCtrl to version 1.61</p>
 554 <p>Improved image HitTest for TreeListCtrl.</p>
 555 <p>Added wx.App.IsMainLoopRunning.</p>
 556 <p>wxGTK: Make wxComboBox spit out a bit fewer surplus events when
 557 holding down the mouse button.</p>
 558 <p>wxGTK: Enable key based navigation through notebook tabs as in the
 559 native control with Left and right keys. Support for vetoing.</p>

 649 <p>wx.ADJUST_MINSIZE is now the default behaviour for window items in
 650 sizers.  This means that the item's GetMinSize and/or GetBestSize will
 651 be called when calculating layout and the return value from that will
 652 be used for the minimum size used by the sizer.  The wx.FIXED_MINSIZE
 653 flag was added that will cause the sizer to use the old behaviour in
 654 that it will <em>not</em> call the window's methods to determine the new best
 655 size, instead the minsize that the window had when added to the sizer
 656 (or the size the window was created with) will always be used.  Please
 657 see the Sizers section in the Migration Guide for more details.</p>
 658 <p>Added new MaskedEditControl code from Will Sadkin.  The modules are
 659 now locaed in their own sub-package, wx.lib.masked.  Demos updated.</p>
 660 <p>The changes that implemented the incompatible wx.DC methods in 2.5.1.5
 661 have been reverted.  The wx.DC methods are now compatible with the 2.4
 662 implemetation.  In addition a set of renamed methods have been added
 663 that take wx.Point and/or wx.Size objects instead of individual
 664 parameters.</p>
 665 <p>Added wx.lib.mixins.listctrl.TextEditMixin, a mixin class that allows
 666 all columns of a wx.ListCtrl in report mode to be edited.</p>
 667 <p>Deprecated the wx.iewin module.</p>
 668 <p>Deprecated the wx.Sizer.AddWindow, AddSizer, AddSpacer methods as well
 669 as their Insert* and Prepend* counterparts.</p>
 670 <p>Added a generic StaticBitmap class in wx.lib.statbmp for the same
 671 reasons that stattext was created, so it could be mouse sensitive on
 672 all platforms like normal windows.  Also updated stattext.py and
 673 buttons.py to handle attribute (font &amp; colour) defaults and
 674 inheritance the new way.  If you have custom controls of your own you
 675 should review stattxt.py or one of the others to see how it is to be
 676 done.</p>
 677 <p>wx.InitAllImageHandlers is now an empty function that does nothing but
 678 exist for backwards compatibility.  The C++ version is now called
 679 automatically when wxPython is initialized.  Since all the handlers
 680 are included in the wxWidgets shared library anyway, this imposes only
 681 a very small amount of overhead and removes several unneccessary
 682 problems.</p>
 683 <p>Replaced wx/lib/pubsub.py with a version that uses weak references to
 684 track the subscribers, plus other fixes/additions.  Thanks go to
 685 Oliver Schoenborn and Robb Shecter.</p>
 686 <p>wxGTK now uses gtk_init_check so wxPython can raise an exception if
 687 there is no DISPLAY available or other initializaion problem.</p>
 688 <p>wx.GetKeyState now has an implementation for wxGTK and is able to
 689 detect the up/down or toggle state of modifier and toggle keys.</p>
 690 <p>The LC_NUMERIC locale is now reset back to &quot;C&quot; (compatibility) when
 691 running on wxGTK to work around the fact that GTK requires the locale
 692 to be set to the system settings but Python depends on LC_NUMERIC
 693 remaining compatible with &quot;C&quot;.</p>
 694 <p>Switched gizmos.TreeListCtrl to the newer version of the code from the
 695 wxCode project.</p>
 696 <p>OGL is dead! LONG LIVE OGL!  (Oops, sorry.  A bit of my dramatic side
 697 leaked out there...)  The wx.ogl module has been deprecated in favor
 698 of the new Python port of the OGL library located at wx.lib.ogl
 699 contributed by Pierre Hjälm.  This will hopefully greatly extend the
 700 life of OGL within wxPython by making it more easily maintainable and
 701 less prone to getting rusty as there seems to be less and less
 702 interest in maintaining the C++ version.  At this point there are just
 703 a couple minor known compatibility differences, please see the
 704 <a class="reference" href="MigrationGuide.html">MigrationGuide</a> file for details.</p>
 705 <p>EVT_STC_POSCHANGED has been removed as it has been deprecated in
 706 Scintilla for several releases now.</p>
 707 <p>All the Window and GDI (pen, bitmap, etc.) class constructors and also
 708 many toplevel functions and static methods will now check that a
 709 wx.App object has already been created and will raise a
 710 wx.PyNoAppError exception if not.</p>
 711 <p>Added more default args as needed to allow most window types to be
 712 constructed with only the parent window arg.  In some cases other args
 713 may be required for normal operation, but they can usually be set
 714 after construction.</p>
 715 <p>Removed the deprecated ErrorDialogs and PythonBitmaps modules.  If you
 716 were using these in your apps then please join wxPython-dev and assist
 717 with a more modern reimplementation.</p>
 718 <p>Added a new version (0.8.3) of FloatCanvas from Chris Barker.  It's now
 719 in a subpackage of wx.lib.</p>
 720 <p>It is now possible to change the tab traversal order of controls on a
 721 panel or dialog.  For details see the new MoveAfterInTabOrder and
 722 MoveBeforeInTabOrder methods of wx.Window.</p>
 723 <p>Applied (and heavily modified) a patch from Eugene
 724 &lt;<a class="reference" href="mailto:svip123&#64;fastmail.fm">svip123&#64;fastmail.fm</a>&gt; that allows the sample modules in the demo to be
 725 edited and reloaded, all from within the demo.  You can switch back
 726 and forth between the default and your edited version, and any errors
 727 ocurring upon the reload are reported on the Demo tab.</p>
 728 <p>Added a menu item in the demo that will open a PyShell window that has
 729 the app and demo frame preloaded in the namespace.  This is another
 730 good way to explore and play with the objects in the currently running
 731 sample.  For example, load the Button sample and then do the following
 732 in the PyShell:</p>
 733 <pre class="literal-block">
 734 &gt;&gt;&gt; b = frame.demoPage.GetChildren()[0]
 735 &gt;&gt;&gt; for x in range(0, 500, 10):
 736 ...     b.Move((x, 50))
 737 ...     app.Yield(True)
 738 ...     wx.MilliSleep(10)
 739 </pre>
 740 <p>wxGTK: Applied wxNO_BORDER patch (#1098374) for text control and combo
 741 box.</p>

 751 <p>The wxWindows project and library is now known as wxWidgets.  Please
 752 see <a class="reference" href="http://www.wxwindows.org/name.htm">http://www.wxwindows.org/name.htm</a> for more details.  This won't
 753 really affect wxPython all that much, other than the fact that the
 754 wxwindows.org domain name will be changing to wxwidgets.org, so mail
 755 list, CVS, and etc. addresses will be changing.  We're going to try
 756 and smooth the transition as much as possible, but I wanted you all to
 757 be aware of this change if you run into any issues.</p>
 758 <p>Many, many little fixes, changes and additions done as part of the move
 759 to wxWidgets 2.5 that I have forgotten about.</p>
 760 <p>Added wxMirrorDC.</p>
 761 <p>Added wxIconLocation</p>
 762 <p>Added Python wrappers and demos for the new wxVScrolledWindow,
 763 wxVListBox, and wxHtmlListBox classes.</p>
 764 <p>Added wrappers for wxBookCtrl and wxListbook.  wxNotebook now derives
 765 from wxBookCtrl.</p>
 766 <p>Added Gordon Williams' PyPlot module to the library, available as the
 767 wx.lib.plot module.</p>
 768 <p>I made a small but important change in the code that aquires the
 769 Python Global Interpreter Lock to try and prevent deadlocks that can
 770 happen when there are nested attempts to aquire the GIL.</p>
 771 <p>The RPMs will now install menu items on Mandrake Linux in
 772 Applications/Development/Tools for PyCrust, XRCed, etc.  The RPMs are
 773 also installing icons and <tt class="docutils literal"><span class="pre">*.desktop</span></tt> items in the generic KDE and
 774 GNOME locations, but I don't know yet if they are resulting in menu
 775 items on non-Mandrake systems.  (It didn't automatically do it on my
 776 RH-9 build box but I didn't chase it very far...)  If you have ideas
 777 for how to improve the .spec file to work better and/or on more
 778 distros please send me a patch.</p>
 779 <p>The RPMs are now built on a fairly generic RH-9 box, and I have tested
 780 installing them also on my main Mandrake 9.2 box.</p>
 781 <p>There are some big changes in the OS X disk image.  The actual
 782 Installer package now <em>only</em> installs the wxMac dynlibs, wxPython
 783 extension modules and Python packages, and also the command-line tool
 784 scripts. The remaining items (demo, samples, and application bundles
 785 for the Demo, PyCrust and XRCed) are now top-level items in the disk
 786 image (.dmg file) that users can just drag and drop to wherever they
 787 want to put them.</p>
 788 <p>The wxWave class has been renamed to wxSound, and now has a slightly
 789 different API.</p>
 790 <p>Updated the AnalogClockWindow with many enhancements from E. A. Tacão.</p>
 791 <p>wxMac now has wx.ToggleButton!</p>
 792 <p>wx.stc.StyledTextCtrl has been updated to version 1.58 of Scintilla.</p>
 793 <p>To help with the wx.stc.StyledTextCtrl performance issues on wxMac
 794 I've added a SetUseAntiAliasing method (and GetUseAntiAliasing too)
 795 that will turn off the use of antialiased fonts in the wxSTC, allowing
 796 it to bypass the slow text measuring routines and use the fast and
 797 simple one instead.  By default the setting is turned off (on wxMac
 798 only.)  When run on OSX the Py* apps have a new item on the Options
 799 menu for controlling this setting if you would like to experiment with
 800 it.</p>
 801 <p>Updated wx.lib.calendar with many fixes and enhancements from Joerg
 802 &quot;Adi&quot; Sieker.</p>
 803 <p>Added wx.Display and wx.VideoMode.</p>
 804 <p>AppleEvents can be handled by overriding wx.App methods MacOpenFile,
 805 MacPrintFile, MacNewFile, and MacReopenApp.</p>
 806 <p>Added wx.PlatformInfo which is a tuple containing strings that
 807 describe the platform and build options of wxPython.  See the
 808 MigrationGuide for more details.</p>
 809 <p>Created a new extension module &quot;activex&quot; from Lindsay Mathieson's
 810 newest <a class="reference" href="http://members.optusnet.com.au/~blackpaw1/wxactivex.html">wxActiveX</a> class.  (The existing iewin module used an older
 811 version of this code, but only exposed the wxIEHtmlWin class.)  This
 812 new module will (in theory ;-) ) allow you to host arbitrary ActiveX
 813 controls in a wx.Window, <strong>without</strong> requiring the use of the win32com
 814 and other PyWin32 modules!  This should eliminate the cronic problems
 815 that have resulted from minor mismatches in how PyWin32 handles the
 816 GIL and tstate when making callbacks, etc.  The older iewin module
 817 will be left in this release as the new stuff is not fully backwards
 818 compatible, but you should migrate your code to the new IEHtmlWindow
 819 in wx.lib.iewin, so the old one can be eventually removed.
 820 Additionally, I've always considered that the wx.lib.activexwrapper
 821 module is an ugly hack that I only included in the lib because I
 822 couldn't figure out anything better.  Well now we have something that,
 823 if it isn't already, has the potential to be better.  So consider
 824 migrating away from using activexwrapper as well.  Please see the
 825 MigrationGuide for more details on using the new module.</p>
 826 <p>Floats are allowed again as function parameters where ints are expected.</p>

 833 <p>Use wxSTC in the demo for displaying the soucre code of the samples.</p>
 834 <p>Lots of bug fixes and such from the wxWindows folks.</p>

 846 <p>Added wxScrolledPanel from Will Sadkin</p>
 847 <p>Added SetShape method to top level windows (e.g. wxFrame.)</p>
 848 <p>Changed wxSWIG to not generate Python code using apply, (since it will
 849 be deprecated in the future) wxSWIG will use <tt class="docutils literal"><span class="pre">spam(*args,</span> <span class="pre">**kw)</span></tt> syntax
 850 instead.  Also changed the generated __repr__ methods to be a bit more
 851 informative.</p>
 852 <p>Made the version number information more robust and uh, informative.
 853 Also added asserts to check that the major.minor versions of wxPython
 854 and wxWindows match.</p>
 855 <p>Added the new wx &quot;renamer&quot; package that will dynamically import from
 856 the wxPython package and rename wxFooBar --&gt; FooBar.  That means that
 857 people can do imports without <tt class="docutils literal"><span class="pre">&quot;import</span> <span class="pre">*&quot;</span></tt> and can use names like
 858 wx.Frame instead of wx.wxFrame.  This is phase 1 of a full transition
 859 to the new namespace.</p>
 860 <p>Updated Scintilla to 1.52.  I also changed it to use wxListCtrl
 861 instead of wxListBox for the AutoComplete window, added the ability to
 862 use custom bitmaps in the margin and in the AutoComplete windows, and
 863 worked out how to do proper clipping of child windows on wxGTK.</p>
 864 <p>Patrick O'Brien's PyCrust package has been renamed to Py and now
 865 includes several new tools.  As part of the change the location of the
 866 pacakge has changed as well, it is now accessible as &quot;from wxPython
 867 import py&quot; (or &quot;from wx import py&quot; using the new namespace.)  There
 868 are still some transition modules in the wxPython.lib.PyCrust package
 869 that will issue a warning and then import what is needed from the new
 870 package.  These will be removed in a future release.</p>
 871 <p>Added __nonzero__ method to wxTreeItemId, wxBitmap, wxImage, wxFont,
 872 and most other classes that have an Ok or IsOK method.  This allows
 873 code like &quot;if obj: ...&quot; to be the same as &quot;if obj.IsOk(): ...&quot;</p>
 874 <p>Toolbars on wxMac can now have controls on them.</p>
 875 <p>Added wxPython.lib.analogclock module based on samples that were
 876 passed back and forth on wxPython-users a while back.</p>
 877 <p>Added masked edit controls (wxPython.lib.maskededit) by Jeff Childers
 878 and Will Sadkin.  Updated wxTimeCtrl to use MaskedEdit.</p>
 879 <p>When the __class__ of a dead object is replaced with _wxPyDeadObject
 880 the __del__ of the original class is now called first.</p>
 881 <p>Added wxTreeListCtrl.  (Looks like a wxTreeCtrl embedded in a
 882 wxListCtrl, but actually is just giving multiple columns to a
 883 wxTreeCtrl.)</p>
 884 <p>Added wxFutureCall, a subclass of wxTimer that makes it easy to delay
 885 a call to any Python callable object.</p>
 886 <p>Added wxPy versions of wxPrintPreview, wxPreviewFrame, and
 887 wxPreviewControlBar so they can be derived from in Python and be able
 888 to override the C++ virtual methods.</p>
 889 <p>Simplified how the wxSizer methods are wrapped, changed the name of
 890 the &quot;option&quot; parameter to &quot;proportion&quot; to match the docs (&quot;option&quot; is
 891 still accepted for compatibility, but this will go away in a future
 892 release,) SetItemMinSize can now take a wxSize (or 2-tuple) parameter,
 893 and Spacers can be specified with a wxSize (or 2-tuple) parameter</p>
 894 <p>Added wxCursorFromBits.</p>

 901 <p>Gave up on generating a warning upon the use of the old true/false or
 902 TRUE/FALSE values.</p>
 903 <p>Fixed wxGenericTreeCtrl (used on wxGTK and wxMac for wxTreeCtrl) so
 904 that it can successfully handle lots of nodes instead of overflowing
 905 when the virtual height of the widget overflowed a 16-bit value.</p>
 906 <p>Fixed the typemap that converts strings to wxColours to also accept
 907 unicode.</p>
 908 <p>Fixed problem where the wrong class name could sometimes be used for
 909 OOR.</p>
 910 <p>Fixed an interpreter lock problem in the __eq__ and __ne__ methods in
 911 wxSize and etc.</p>
 912 <p>Updated PyCrust to version 0.9</p>
 913 <p>Instead of always logging C++ assertions, added wxPYAPP_ASSERT_LOG
 914 flag to turn it on.  In most cases turning it into an exception (the
 915 default behavior) is enough.  See below in the 2.3.4.1 notes for more
 916 details.</p>

 941 <p>Added missing wxRect methods</p>
 942 <p>Add OOR support for wxApp objects too.</p>
 943 <p>Added wxCursorFromImage, which works on wxMSW and wxGTK so far.</p>
 944 <p>All platforms now send EVT_DESTROY_WINDOW.  Be warned that at the time
 945 the event is sent the window is in the process of being deconstructed,
 946 and so calling some (most?) methods of the window itself may cause
 947 problems.</p>
 948 <p>Fixed SF Bug #689481, a method in the OGL wrappers was using the wrong
 949 return type.</p>
 950 <p>Fixed SF Bug #689958, an endless loop in printout.py.</p>
 951 <p>Added EVT_WINDOW_CREATE_ID and EVT_WINDOW_DESTROY_ID so these events
 952 can be associated with a specific window ID and more easily caught by
 953 the parent window.</p>
 954 <p>Fixed copy-paste error in wxListCtrl.GetFirstSelected.</p>
 955 <p>Added missing Init method (and an overloading wrapper) to wxLocale
 956 wrapper.</p>
 957 <p>Added a wxBitmap.SetMaskColour convenience method.</p>
 958 <p>Changed how the dynamic event tables (used for all Python wx classes,
 959 C++ wx classes typically use static event tables) are searched such
 960 that they behave from a Python perspective more like the static tables
 961 in C++.  Namely that if there are identical event bindings in a base
 962 Python class and a derived Python class that the one in the derived
 963 class will be found first and that if Skip is called that the one in
 964 the base class will still be found instead of skipping directly to the
 965 static stable in the C++ class.</p>
 966 <p>Switched to using True/False in the wxPython lib and demo instead of
 967 true/false or TRUE/FALSE to prepare for the new boolean type and
 968 constants being added to Python.  Added code to wx.py to test for the
 969 existence of the new constants and to create suitable values if not
 970 present.</p>
 971 <p>Added some static wxApp functions that help with integration with the
 972 Mac UI.  They are no-ops on other platforms so it doesn't hurt to
 973 always call them.  The functions are:</p>
 974 <pre class="literal-block">
 975 wxApp_GetMacDefaultEncodingIsPC
 976 wxApp_GetMacSupportPCMenuShortcuts
 977 wxApp_GetMacAboutMenuItemId
 978 wxApp_GetMacPreferencesMenuItemId
 979 wxApp_GetMacExitMenuItemId
 980 wxApp_GetMacHelpMenuTitleName
 981 wxApp_SetMacDefaultEncodingIsPC
 982 wxApp_SetMacSupportPCMenuShortcuts
 983 wxApp_SetMacAboutMenuItemId
 984 wxApp_SetMacPreferencesMenuItemId
 985 wxApp_SetMacExitMenuItemId
 986 wxApp_SetMacHelpMenuTitleName
 987 </pre>
 988 <p>Refactored, enhanced and added capabilities for the DrawXXXList
 989 functions, inspired by code from Chris Barker.</p>
 990 <p>The wxWindows .mo language catalog files are now installed in a
 991 subdirectory of the wxPython package dir on MSW since that platform
 992 doesn't have a standard place for them.</p>
 993 <p>Added missing deselect methods for wxGrid.</p>
 994 <p>Fixed typemaps for wxGridCellCoordsArray.</p>

1029 <p>Show a couple new wxGrid features in the demo.</p>
1030 <p>Several bug fixes in wxWindows.</p>
1031 <p>Added wxHtmlFilter.</p>
1032 <p>wxASSERT and related C++ runtime diagnostics are now converted to
1033 Python exceptions.  When an assert happens a wxPyAssertionError
1034 (which derives from AssertionError) exception is created and when
1035 control returns back to the Python code that invoked the C++ API it
1036 will be raised.  The same exception restrictions are in place as
1037 before, namely that exceptions can't cross from one Python layer
1038 through C++ to another Python layer.  That simply means that if you
1039 want to catch wxPyAssertionError or any other exception that you need
1040 to do it before control returns to C++ at the end of your event
1041 handler or callback code.  There is some test code in demo/wxButton.py
1042 you can use to play with this new feature.</p>
1043 <p>Added some methods to wxApp (SetAssertMode and GetAssertMode) that let
1044 you control how C++ assertions are processed.  Valid modes are:
1045 wxPYAPP_ASSERT_SUPPRESS, wxPYAPP_ASSERT_EXCEPTION, and
1046 wxPYAPP_ASSERT_DIALOG.  Using _SUPPRESS will give you behavior like
1047 the old &quot;final&quot; builds and the assert will be ignored, _EXCEPTION is
1048 the new default described above, and _DIALOG is like the default in
1049 2.3.3.1 and prior &quot;hybrid&quot; builds.  You can also combine _EXCEPTION
1050 and _DIALOG if you wish, although I don't know why you would.</p>
1051 <p>You can now overload OnInitGui, OnExit and OnAssert in your classes
1052 derived from wxApp.</p>
1053 <p>Added GetSelectedCells, GetSelectionBlockTopLeft,
1054 GetSelectionBlockBottomRight, GetSelectedRows, GetSelectedCols nethods
1055 to wxGrid.</p>
1056 <p>Added Python == and != operators for some basic classes</p>
1057 <p>Fixed the Python wrappers for wxInputStream so they no longer block
1058 when reading from a wxProcess on wxGTK.  They now work more or less as
1059 they did before 2.3.3.1 but the dual meaning of eof() has been
1060 removed.  There is now a CanRead() method that lets you know if there
1061 is data waiting to be read from the pipe.</p>
1062 <p>Fixed method name clash in wxIEHtmlWin, renamed Refresh to RefreshPage.</p>
1063 <p>Added Throbber from Cliff Wells to the library and the demo.</p>
1064 <p>Windows installer prompts to uninstall old version first.</p>
1065 <p>Added wxPython.lib.evtmgr by Robb Shecter, which is an easier, more
1066 &quot;Pythonic&quot; and more OO method of registering handlers for wxWindows
1067 events using the Publish/Subscribe pattern.</p>
1068 <p>Added wxPython.lib.popupctl by Gerrit van Dyk which is a combobox-like
1069 gizmo for poping up arbitrary controls.  It is currently using
1070 wxDialog because of some issues with wxPopupWindow...</p>
1071 <p>Added wxPython.lib.gridmovers by Gerrit van Dyk which facilitates the
1072 dragging of columns and/or rows in a wxGrid.</p>
1073 <p>Added wxPython.lib.multisash by Gerrit van Dyk which is a nice
1074 implementation of allowing the user to split a window any number of
1075 times either horizontally or vertically, and to close the split off
1076 windows when desired.</p>
1077 <p>Added helpviewer tool that displays HTML books similarly to how MS
1078 HTMLHelp viewer does.  Changed how the wxPythonDocs tarball is built
1079 and added a script to launch the doc viewer.</p>

1087 <p>Added wxGenericDirCtrl.</p>
1088 <p>Added wxMultiChoiceDialog.</p>
1089 <p>The calltip window and autocomplete window in wxSTC will now use a
1090 wxPopupWindow if available on the platform (and functioning correctly)
1091 so they can extend beyond the client area of the STC if needed.</p>
1092 <p>Finished wrapping and providing typemaps for wxInputStream and also
1093 added the stream ctor and other methods for wxImage so images can now
1094 be loaded from any Python &quot;file-like&quot; object.</p>
1095 <p>Changed the img2py tool to use PNG instead of XPM for embedding image
1096 data in Python source code, and the generated code now uses streams to
1097 convert the image data to wxImage, wxBitmap, or wxIcon.</p>
1098 <p>Added the wxPython.lib.rcsizer module which contains RowColSizer.
1099 This sizer is based on code from Niki Spahiev and lets you specify a
1100 row and column for each item, as well as optional column or row
1101 spanning.  Cells with no item assigned to it are just left blank.
1102 Stretchable rows or columns are specified and work the same as in
1103 wxFlexGridSizer.</p>
1104 <p>Updated XRCed from Roman Rolinsky</p>
1105 <p>Added wxBufferedDC.</p>
1106 <p>Upgraded wxSTC from Scintilla 1.40 to Scintilla 1.45, and then again
1107 to version 1.47, and one more time to 1.48! &lt;wink&gt;</p>
1108 <dl class="docutils">
1109 <dt>UNICODE!</dt>
1110 <dd><p class="first">wxWindows/wxPython can be compiled with unicode support enabled or
1111 disabled.  Previous to wxPython 2.3.3 non-unicode mode was always
1112 used.  Starting with 2.3.3 either mode is supported, but only if
1113 it is also available in wxWindows on the platform.  Currently
1114 wxWindows only supports unicode on MS Windows platforms, but with
1115 the recent release of GTK+ 2.0 it is only a matter of time until
1116 it can be done on wxGTK (Linux and other unixes) as well.</p>
1117 <p>Unicode works best on platforms in the NT branch of the Windows
1118 family tree (NT, win2k, XP) but it is now also possible to use the
1119 same unicode binaries on win95/98/ME platforms as well!  This is
1120 done by using a special library and DLL with the application
1121 called MSLU, (Microsoft Layer for Unicode).  It simply gets out of
1122 the way if the app is run on an NT box, otherwise if run on a
1123 win9x box it loads a special DLL that provides the unicode
1124 versions of the windows API.  So far I have not been able to get
1125 this to work perfectly on win9x.  Most things work fine but
1126 wxTaskBarIcon for example will cause a crash if used with the
1127 unicode build on win95.</p>
1128 <p class="last">So how do you use it?  It's very simple.  When unicode is enabled,
1129 then all functions and methods in wxPython that return a wxString
1130 from the C++ function will return a Python unicode object, and
1131 parameters to C++ functions/methods that expect a wxString can
1132 accept either a Python string or unicode object.  If a string
1133 object is passed then it will be decoded into unicode using the
1134 converter pointed to by wxConvCurrent, which will use the default
1135 system encoding.  If you need to use a string in some other
1136 encoding then you should convert it to unicode using the Python
1137 codecs first and then pass the unicode string to the wxPython
1138 method.</p>
1139 </dd>
1140 </dl>
1141 <p>Added wxListCtrlAutoWidthMixin from Erik Westra.</p>
1142 <p>Added wxIconBundle and wxTopLevelWindow.SetIcons.</p>
1143 <p>Added wxLocale and wxEncodingConverter.</p>
1144 <p>A little black magic...  When the C++ object (for a window or
1145 whatever) is deleted there is no way to force the Python shadow object
1146 to also be destroyed and clean up all references to it.  This leads to
1147 crashes if the shadow object tries to call a method with the old C++
1148 pointer.  The black magic I've done is to replace the __class__ in the
1149 Python instance object with a class that raises an exception whenever
1150 a method call (or other attribute access) is attempted.  This works
1151 for any class that is OOR aware.</p>
1152 <p>Added OOR support for wxGridCellRenderer, wxGridCellEditor,
1153 wxGridCellAttr, wxGridCellAttrProvider, wxGridTableBase and their
1154 derived classes.</p>
1155 <p>Added wxImage.GetDataBuffer which returns an in-place edit buffer of
1156 the image data.  (Patch #546009)</p>
1157 <p>Added a sample that shows how to embed wxPython in a wxWindows C++
1158 application.</p>
1159 <p>Added wxPyWindow, wxPyPanel and wxPyControl which are just like their
1160 wx counterparts except they allow some of the more common C++ virtual
1161 methods to be overridden in Python derived classes.  The methods
1162 supported are:</p>
1163 <blockquote>
1164 <p>DoMoveWindow
1165 DoSetSize
1166 DoSetClientSize
1167 DoSetVirtualSize
1168 DoGetSize
1169 DoGetClientSize
1170 DoGetPosition
1171 DoGetVirtualSize
1172 DoGetBestSize
1173 InitDialog
1174 TransferDataFromWindow
1175 TransferDataToWindow
1176 Validate
1177 AcceptsFocus
1178 AcceptsFocusFromKeyboard
1179 GetMaxSize
1180 AddChild
1181 RemoveChild</p>
1182 <p>If there are other methods that you think should be supported
1183 please let me know.</p>
1184 </blockquote>
1185 <p>Changed wxGenButton to derive from wxPyControl and overload
1186 DoGetBestSize and AcceptsFocus.</p>
1187 <p>Added wxArtProvider.</p>
1188 <p>Added wxCallAfter which is a helper function that registers a function
1189 (or any callable Python object) to be called once the next time there
1190 are no pending events.  This is useful for when you need to do
1191 something but it can't be done during the current event handler.  The
1192 implementation is very simple, see wxPython/wx.py.</p>
1193 <p>Fixed a boatload of reference leaks.</p>
1194 <p>Added a demo of using a sizer in a wxScrolledWindow, in effect
1195 creating a ScrolledPanel.</p>
1196 <p>Added a sample to the demo that shows how to use radio menu items, and
1197 other menu stuff.</p>
1198 <p>Added wxIEHtmlWin.  This is essentially the same as using IE with the
1199 ActiveXWrapper already in the library, but it is implemented all in
1200 C++ and therefore does not need any of the modules from win32all and
1201 so it is less fragile in the face of changes.</p>
1202 <p>Fixed the ActiveXWrapper problem.  Looks like when the win32com
1203 modules make a &quot;callback&quot; that they (incorrectly, IMHO) allocate a
1204 transient thread state structure.  Since wxPython is now saving
1205 tstates for it's own callbacks it ended up using garbage after
1206 win32com got rid of the temporary tstate...</p>
1207 <p>Added a generic static text control to wxPython.lib.stattext.  This is
1208 so things like Boa and PythonCard can have a static text that can
1209 respond to mouse events and etc.</p>
1210 <p>Changed the wxDateTime.Parse* methods to return an int that will be -1
1211 on failure, and the index where parsing stopped otherwise.</p>
1212 <p>Moved tools to be a Python package in wxPython.tools, added scripts to
1213 import and launch each tool.  This will let you import and use the
1214 tools in your own scripts or apps as needed.  On Linux and OS X the
1215 tool scripts are installed to {prefix}/bin so you should be able to
1216 easily launch them from the command line.  For example, PyCrust can be
1217 started with just the &quot;pycrust&quot; command.</p>
1218 <p>Added a sample to the demo that catches various key events and
1219 displays the details of the event.</p>
1220 <p>Added wxWizard, wxWizardPage, wxWizardPageSimple and wxPyWizardPage.</p>
1221 <p>Added wxXmlResourceHandler which allows you to create custom handlers
1222 for nonstandard class types in XRC resources.  See the demo for an
1223 example.</p>
1224 <p>Added wxPython.lib.mixins.rubberband module from Robb Shecter.</p>
1225 <p>Added wxTimeCtrl from Will Sadkin.</p>

1229 <ul class="simple">

1231 </ul>
1232 <p>Changed (again) how the Python global interpreter lock is handled as
1233 well as the Python thread state.  This time it works on SMP machines
1234 without barfing and is also still compatible with Python debuggers.</p>
1235 <p>Added some patches from library contributors.</p>

1242 <p>Added EVT_HELP, EVT_HELP_RANGE, EVT_DETAILED_HELP,
1243 EVT_DETAILED_HELP_RANGE, EVT_CONTEXT_MENU, wxHelpEvent,
1244 wxContextMenuEvent, wxContextHelp, wxContextHelpButton, wxTipWindow,
1245 and a demo to show them in action.</p>
1246 <p>Deprecated PyShell and PyShellWindow, added a snapshot of PyCrust (see
1247 <a class="reference" href="http://sourceforge.net/projects/pycrust/">http://sourceforge.net/projects/pycrust/</a>. )</p>
1248 <p>Added the new virtual list capabilities to wxListCtrl.</p>
1249 <p>Added a wxSTC style editor from Riaan Booysen to the sample apps.</p>
1250 <p>Added XRCed to the wxPython Tools directory, contributed by Roman
1251 Rolinsky.</p>
1252 <p>Added a new &quot;constructor&quot; to most of the window classes that calls the
1253 default C++ constructor, (the one with no parameters) and also added the
1254 corresponding  Create(...) method.  This allows you to do a 2-step
1255 creation of windows which is sometimes required for doing things such
1256 as setting extended style flags before the window is created, or for
1257 passing the object to the XRC resource system to be created from the
1258 resource.  The name of the new &quot;constructor&quot; is the original name of
1259 the class with a &quot;Pre&quot; in it.  For example, wxPreWindow, wxPreFrame,
1260 etc.</p>
1261 <p>Updated to version 1.40 of Scintilla and updated wxStyledTextCtrl
1262 accordingly.  While doing this update I dropped the wxLB_SORT style
1263 from the wxListBox created for the AutoComplete functionality.  This
1264 means that you will have to sort the keyword lists yourself, but you
1265 are free to do case sensitive or case insensitive sorts and set the
1266 wxSTC flag accordingly.</p>
1267 <p>Updated wxColumnSorterMixin to also be able to place sort icons on the
1268 column headers, and updated the wxListCtrl demo to show it off by
1269 using wxColumnSorterMixin.</p>
1270 <p>Added wxGenBitmapTextButton, TablePrint, etc. contribs from Lorne White.</p>
1271 <p>Added wxNativeFontInfo and wxFontMapper.</p>
1272 <p>Added pySketch to the samples.</p>
1273 <p>Significantly changed how the Python interpreter lock and thread state
1274 are managed, which should fix the problem of running on a
1275 multi-processor machine.</p>
1276 <p>Added wxPyLog so log targets can be created in Python to handle log
1277 messages however is wished.  See demo/Main.py for an example.</p>
1278 <p>Added wxFindReplaceDialog.</p>
1279 <p>The second phase of OOR is implemented for wxEvtHandler, wxSizer,
1280 wxShape and derived classes.  This means that functions and methods
1281 that return an object derived from wxEvtHandler that was originally
1282 created in Python, will return the original Python object (if it still
1283 exists) instead of letting SWIG wrap a new shadow object around the
1284 original C++ pointer.</p>
1285 <p>Added some optimization methods to wxDC: GetBoundingBox, DrawLineList,
1286 DrawPointList.</p>
1287 <p>Added a set of sophisticated Error Dialogs from Chris Fama.</p>
1288 <p>Added wxRightTextCtrl from Josu Oyanguren to wxPython.lib for aligning
1289 text in a wxTextCtrl to the right side.</p>
1290 <p>Added wxURLDataObject and an example showing drag and drop of URLs to
1291 and from web browsers.  It's still not 100% bullet-proof for all types
1292 of browsers, but it works for the majority of cases with the popular
1293 browsers on Windows.  On wxGTK it seems that only Netscape 4.x works,
1294 if anybody has any suggestions about this please bring it up on the
1295 wx-dev list.</p>
1296 <p>Added wxStopWatch.</p>
1297 <p>Added wxMimeTypesManager and wxFileType.</p>
1298 <p>Passing None for the handler parameter to one of the EVT_** functions
1299 will now Disconnect the event.</p>
1300 <p>Added wxPopupWindow and wxPopupTransientWindow.</p>
1301 <p>Added wxFileHistory.</p>
1302 <p>Added wxDynamicSashWindow, which allows you to endlessly split windows
1303 by dragging a little tab next to the scrollbars.  Added a demo to show
1304 this and also the ability of multiple wxStyledTextCtrls to share the
1305 same document.</p>
1306 <p>Added wxEditableListBox gizmo.</p>
1307 <p>Updated wxEditor with lots of enhancements from Steve Howell and Adam
1308 Feuer.</p>
1309 <p>Added the &quot;SplitTree gizmos&quot; which are a collection of classes that
1310 were designed to operate together and provide a tree control with
1311 additional columns for each item.  The classes are
1312 wxRemotelyScrolledTreeCtrl, wxTreeCompanionWindow,
1313 wxThinSplitterWindow, and wxSplitterScrolledWindow, some of which may
1314 also be useful by themselves.</p>
1315 <p>Added wxDllWidget from Vaclav Slavik which allows wx widgets derived
1316 from wxWindow to be loaded from a C++ .dll (or .so) and be used in a
1317 wxPython program, without the widget having to be SWIGged first.  The
1318 visible API of the widget is limited to wxWindow methods plus a
1319 SendCommand method, but it is still quite powerful.  See
1320 wxPython/contrib/dllwidget and wxPython/demo/dllwidget for more
1321 details.</p>

1328 <p>Added EVT_GRID_EDITOR_CREATED and wxGridEditorCreatedEvent so the user
1329 code can get access to the edit control when it is created, (to push
1330 on a custom event handler for example.)</p>
1331 <p>Added wxTextAttr class and SetStyle, SetDefaultStyle and
1332 GetDefaultStyle methods to wxTextCtrl.</p>
1333 <p>Added ability to use xml resource files.  Still need to add ability to

1345 <p>Removed initial startup dependency on the OpenGL DLLs so only the
1346 glcanvasc.pyd depends on them, (on wxMSW.)</p>
1347 <p>Changed wxFont, wxPen, wxBrush to not implicitly use the
1348 wxThe[Font|Pen|Brush]List objects behind the scenes, but to use normal
1349 ctor and dtors.</p>
1350 <p>Exposed the wxThe[Font|Pen|Brush]List to wxPython.</p>
1351 <p>Also added wxTheColourDatabase and added a library module (in the
1352 wxPython.lib.colourdb module) to load LOTS more colour names into the
1353 colour database.</p>
1354 <p>Added wxWakeUpMainThread, wxMutexGuiEnter, wxMutexGuiLeave,
1355 wxMutexGuiLocker and wxThread_IsMain to assist with dealing with GUI
1356 access from non-GUI threads.</p>
1357 <p>wxPyOnDemandOutputWindow is now (more) thread safe if non-GUI threads
1358 use print, sys.stdout.write, etc.</p>
1359 <p>Added CreateTextSizer and CreateButtonSizer to wxDialog</p>
1360 <p>Added wxPython/lib/infoframe.py from Chris Fama.  It contains a class
1361 that can be used in place of wxPyOnDemandOutputWindow.</p>
1362 <p>Added colourselect.py, imagebrowser.py and an updated calendar.py to
1363 wxPython/lib from Lorne White.</p>
1364 <p>Added patch to wxPoint_LIST_helper from Tim Hochberg that should make
1365 it gobs faster in certain situations.</p>
1366 <p>Added tools that will take an image file in a wx supported format and
1367 convert it to data embedded in a Python source file.  The image is
1368 converted to XPM format which is essentially a list of strings
1369 containing info about each pixel.  The image's transparency mask is
1370 included, if there is one, or a mask can be added if a mask colour is
1371 specified on the command line.  It is then pickled and optionally
1372 compressed and written to a Python source file along with functions to
1373 convert it to either a wxBitmap or a wxImage.  See
1374 wxPython/demo/images.py for examples, and wxPython/Tools/img2py.py for
1375 the implementation.</p>
1376 <p>Fixed wxStyledTextCtrl to be much faster on wxGTK.  There was some
1377 experimental code that got left in place that ended up causing way too
1378 many refreshes.</p>
1379 <p>A couple more hacks in my_distutils.py so wxPython can be built with
1380 the distutils that comes with Python 2.1.</p>
1381 <p>Added a ton of missing methods for wxPrintData.</p>
1382 <p>Switched to InnoSetup for MSW distributions.</p>
1383 <p>Added wxToggleButton.</p>
1384 <p>Fixed bug that prevented wxTreeCtrl.OnCompareItems from being called.</p>
1385 <dl class="docutils">
1386 <dt>Added some methods to wxGrid:</dt>

1396 <p>Added wxGetClientDisplayRect which on wxMSW returns a wxRect
1397 representing the area on screen not occupied by the taskbar and such.
1398 On other platforms it is equivallent to wxGetDisplaySize.</p>
1399 <dl class="docutils">
1400 <dt>OOR:</dt>
1401 <dd><p class="first">Implemented the first phase of OOR (Original Object Return).  See
1402 the text in the demo for more details of what this means, but in a
1403 nutshell methods such as wxWindow.GetParent or FindWindowById will
1404 now return a shadow object of the proper type if it can.  By
1405 &quot;proper type&quot; I mean that if the wxWindow pointer returned from
1406 FindWindowById really points to a wxButton then the Python object
1407 constructed will be of a wxButtonPtr class instead of wxWindowPtr
1408 as before.  This should reduce or eliminiate the need for
1409 wxPyTypeCast.  (Woo Hoo!)  The objects returned are still not the
1410 original Python object, but that is the next step.  (Although it
1411 will probably only work on Python 2.1 and beyond because it will
1412 use weak references.)</p>
1413 <p class="last">This first phase of the OOR plan is fairly significant and has
1414 required a lot of changes all over wxPython, most of which should
1415 be transparent to you, however I'm not 100% sure that it didn't
1416 introduce any new bugs that are hiding somewhere and didn't get
1417 stomped on during my testing.  So please be sure to test everything
1418 thoroughly when you install this version and be sure to report any
1419 object-type related oddities to me.</p>
1420 </dd>
1421 </dl>
1422 <p>There is now a wxObject class that most other classes derive from like
1423 in C++, but the methods provided don't really match but are wxPython
1424 specific.  It could have been added long ago but OOR required it so it
1425 finally got done.</p>
1426 <p>Finally added wxPyLineShape.GetLineControlPoints, which has been on my
1427 list for a while.  The above OOR modification made this easier.</p>
1428 <p>Fixed the __cmp__ methods for wxPoint and others.</p>
1429 <p>Added wxWave.</p>
1430 <p>Added the wxPython.lib.mixins package to the library, it is where
1431 useful mix-in classes can be placed.  Currently there is one to help
1432 make the columns in a wxListCtrl sortable, and the MagicIMageList from
1433 Mike Fletcher.  If you have any custom code that can be factored out
1434 of existing classes into a mix-in that would be useful to others
1435 please send it to me for inclusion in this package.</p>
1436 <p>Added a few little sample applications to help newbies to get started
1437 by having smaller functional apps to play with.  They can be found in
1438 wxPython/samples.</p>

1453 <p>New typemaps for wxString when compiling for Python 2.0 and beyond
1454 that allow Unicode objects to be passed as well as String objects.  If
1455 a Unicode object is passed PyString_AsStringAndSize is used to convert
1456 it to a wxString using the default encoding.</p>
1457 <p>Fixed the generic buttons so tool tips work for them.</p>
1458 <p>Fixed a bug in the demo's tree control.</p>
1459 <p>Added a listbox to the listbox demo that shows how to find items with
1460 a matching prefix as keys are typed.</p>
1461 <p>Added code to the wxListCtrl demo to show how to get text from a
1462 column in report mode.</p>
1463 <p>Added code to the toolbar demo to clear the long help from the status
1464 bar after 2 seconds.</p>
1465 <p>Added wxJoystick.</p>
1466 <p>Fixed wxTimer so it can be used as described in the docs, either with
1467 a Notify method in a subclass, or sending an event to a wxEvtHandler
1468 object, (usually a window.)</p>
1469 <p>Added wxNotifyEvent.Allow()</p>
1470 <p>Fixed GOBS of reference leaks.</p>
1471 <p>Massive code changes and cleanup to allow wxPython to be split into
1472 multiple extension modules again.  A Python CObject is used to allow
1473 the &quot;export&quot; of SWIG functions and other common helper functions from
1474 the wxc module to other modules, even if they are in separate shared
1475 libraries.  Should also be usable from 3rd party code, just include
1476 wxPython/src/export.h</p>
1477 <p>Changed the default setup so the following are built as separate
1478 extension modules:  calendar, glcanvas, grid, html, ogl, stc, and
1479 utils.  Will probably add more later.</p>
1480 <p>Changed the wxPrinterDC to use the new constructor taking a
1481 wxPrintData object.  The old ctor is still there using the
1482 wxPrinterDC2 name.</p>
1483 <p>Added wxPython.lib.anchors.py from Riaan Booysen.  It contains a class
1484 that implements Delphi's Anchors with wxLayoutConstraints.</p>
1485 <p>Added wxPython.lib.fancytext from Timothy Hochberg.</p>
1486 <p>Changed the GenericButtons to send their event in idle time, so the
1487 mouse won't be captured when the event handler is called.</p>
1488 <p>Added wxPython.lib.rpcMixin from Greg Landrum, although it's not
1489 integrated with the demo yet.  It allows a wxPython GUI to be an
1490 XML-RPC server.</p>
1491 </div>

1494 <ul class="simple">
1495 <li>26-Oct-2000</li>
1496 </ul>
1497 <p>Significantly changed how the wxStyledtextCtrl code that wraps
1498 Scintilla is implemented.  Most of it is now automatically generated
1499 from an interface definition file provided by Scintilla.  This means
1500 that it will be much easier to stay in sync with new Scintilla
1501 releases, but also means that some of the method and identifier names
1502 have changed.  See wxPython/demo/data/stc.h for a copy of the C++
1503 interface from which the Python interface is generated.  There is now
1504 some inline documentation in that file that should really help explain
1505 how things work.</p>
1506 <p>I am now using the Python Distutils to build wxPython and to make some
1507 of the distribution files.  (See <a class="reference" href="http://www.python.org/sigs/distutils-sig/">http://www.python.org/sigs/distutils-sig/</a>)
1508 This means no more messing with my kludgy build.py/Makefile hack,
1509 builds will be more consistent with other Python extensions that also
1510 use Distutils, and will hopefully make wxPython easier to build for
1511 platforms where there have been troubles before.  If you are building
1512 wxPython for Python 1.5.2 or for 1.6, then you will need to get and
1513 install version 1.0 of Distutils from the website above.  If you are
1514 using Python 2.0 then you already have it.</p>
1515 <p>Added wxInputStream and the wxFileSystem family of classes,
1516 contributed by Joerg Baumann.</p>
1517 <p>Added wxProcess and support for it to wxExecute.  wxProcess lets you
1518 get notified when an asyncronous child process terminates, and also to
1519 get input/output streams for the child process's stdout, stderr and
1520 stdin.</p>
1521 <p>Removed the old python sizers.</p>
1522 <p>Added __add__, __sub__ and __cmp__ (equality check only) for wxPoint
1523 and wxRealPoint.</p>
1524 <p>Changed the build to make one big extension module instead of one for
1525 the core and each contrib.  This allowed me to do away with the
1526 libwxPyHelpers.so on unix systems.</p>
1527 <p>Lots of little fixes here and there.</p>
1528 <p>Some hacks on wxGTK to try and make the AutoComplete listbox in the
1529 wxStyledTextCtrl to behave better.  It's still not as nice as on
1530 wxMSW, but at least it's a bit more usable now.</p>

1563 <p>WARNING: A while back I asked what should be done about the Magic
1564 Method Names.  (Methods that are automatically turned into event
1565 handlers by virtue of their name.)  The consensus was that it is more
1566 confusing to have them than to try and expand them to have greater
1567 coverage.  I am finally getting around to removing the code that
1568 generates the event binding.  This means that if you are using any of
1569 the following method names without a EVT_* call that you need to
1570 modify your code to add the EVT_* to hook the event to the method.</p>
1571 <blockquote>
1572 OnChar

1593 GetSelections.</p>
1594 <p>Fixed some problems in OGL.  Also wxShape.SetClientData and
1595 .GetClientData can now deal with Python objects.</p>
1596 <p>Added wxListCtrl.SortItems and changed the demo to show how to use it.</p>
1597 <p>Plugged a memory leak.</p>
1598 <p>Wrapped the new wxGrid and friends.  The old wxGrid class is no longer
1599 available.  There are some incompatibilities, and unfortunately the
1600 new classes are not documented yet, (however the methods are more
1601 consistent with each other now so you may be able to guess pretty
1602 good...)</p>
1603 <p>Updated filebrowsebutton.py and calendar.py with changes from their
1604 authors.  There is now a FileBrowseButtonWithHistory class (what a
1605 mouthful!) and wxCalendar has printing support.</p>
1606 <p>Added ActiveXWrapper to the library, and some good demos of it too.
1607 It works great for embedding a COM (a.k.a OCX, a.k.a ActiveX) control
1608 in a window and calling its methods.  It actually creates a new class
1609 on the fly that derives from wxWindow, the COM CoClass and others
1610 needed to make it all work.  The resulting class can be instantiated
1611 just like wxWindow, used in sizers, etc.  It also responds to all COM
1612 method calls, properties, etc., and if the class or a mix-in has
1613 matching method names, then the COM events will be propogated back to
1614 them.</p>
1615 <p>Created a typemap that allows a string to be used for parameters
1616 expecting a wxColour type.  The string is either a colour name as
1617 defined in the wxColourDatabase, or a colour spec of the form
1618 &quot;#RRGGBB&quot;.  See the wxStyledTextCtrl demo for an example.</p>
1619 <p>I almost forgot to mention the wxStyledTextCtrl!  Yes, the
1620 wxStyledTextCtrl is finally in wxPython!!  (And the crowd goes
1621 wild...)   There's no documentaTion yet (the crowd boos and hisses...)
1622 but I've included a very readable source file in the
1623 wxPython/demo/data directory, a couple fairly good examples, and you
1624 can also refer to the Scintilla documentaion at
1625 <a class="reference" href="http://www.scintilla.org/ScintillaDoc.html">http://www.scintilla.org/ScintillaDoc.html</a> to help fill in the gaps
1626 until the docs are done.  (The croud murmers contentedly as the tool
1627 provider smiles convincingly and removes his flame-proof suit.)</p>

1632 <li>3-Feb-2000</li>
1633 </ul>
1634 <p>Skipped a version number to match what has been released for wxGTK.</p>
1635 <p>Updated wxMVCTree and added a demo for it, also fixed layout on GTK
1636 and some flicker problems.</p>
1637 <p>Added a wrapper class for the Visualization ToolKit (or VTK) in the
1638 wxPython.lib.vtk module.  (<a class="reference" href="http://www.kitware.com/">http://www.kitware.com/</a>)</p>
1639 <p>Fixed wxTreeCtrl.SetItemImage and GetItemImage to recognise the new
1640 &quot;which&quot; parameter.</p>
1641 <p>Added wxPython.lib.spashscreen from Mike Fletcher.</p>
1642 <p>Added wxPython.lib.filebrowsebutton also from Mike Fletcher.</p>
1643 <p>Renamed wxTreeCtrl.GetParent to GetItemParent to avoid a name clash
1644 with wxWindow.GetParent.</p>
1645 <p>Added wxIntersectRect to compute the intersection of two wxRect's.
1646 It is used like this:</p>
1647 <blockquote>
1648 intersect = wxIntersectRect(rect1, rect2)</blockquote>
1649 <p>If r1 and r2 don't intersect then None is returned, otherwise the
1650 rectangle representing the intersection is returned.</p>
1651 <p>Some bug fixes for Clipboard and Drag-n-Drop.</p>
1652 <p>Rotated text!!!  WooHoo!  (See wxDC.DrawRotatedText())</p>
1653 <p>Added a set of Generic Buttons to the library.  These are simple
1654 window classes that look and act like native buttons, but you can have
1655 a bit more control over them.  The bezel width can be set in addition
1656 to colours, fonts, etc.  There is a ToggleButton as well as Bitmap
1657 versions too.  They should also serve as a good example of how to
1658 create your own classes derived from wxControl.</p>
1659 <p>The C++ wxToolBar classes have been redone, and so have the wxPython
1660 wrappers.  There have been slight modifications to some of the methods
1661 but shouldn't impact anybody too much.  I took the opportunity to add
1662 support for setting user data on each toolbar tool.  The new AddTool
1663 methods look like this:</p>
1664 <blockquote>
1665 <dl class="docutils">
1666 <dt>def AddTool(ID,</dt>
1667 <dd>bitmap,
1668 pushedBitmap = wxNullBitmap,
1669 toggle = FALSE,
1670 clientData = NULL,
1671 shortHelpString = &quot;&quot;,
1672 longHelpString = &quot;&quot;)</dd>
1673 <dt>def AddSimpleTool(ID,</dt>
1674 <dd>bitmap,
1675 shortHelpString = &quot;&quot;,
1676 longHelpString = &quot;&quot;,
1677 toggle=FALSE)</dd>
1678 </dl>
1679 </blockquote>
1680 <p>There are also corresponding InsertTool and InsertSimpleTool methods
1681 that additionally take an integer position as the first parameter.</p>
1682 <p>Added a wrapper for the new PCX and TIFF ImageHandlers.</p>
1683 <p>wxRect now simulates attributes named left, right, top and bottom.</p>
1684 <p>Removed all non wx stuff from the glcanvas module since DA's PyOpenGL
1685 is better and compatible with the wxGLCanvas.  You can get it at
1686 <a class="reference" href="http://starship.python.net:9673/crew/da/Code/PyOpenGL">http://starship.python.net:9673/crew/da/Code/PyOpenGL</a>.</p>
1687 <p>Added some missing EVT functions.</p>
1688 <p>Added Dirk Holtwic's editor classes to the wxPython.lib.editor
1689 package.</p>
1690 <p>Changed all the &quot;LIST&quot; parameter names to &quot;choices&quot; to match the docs.</p>
1691 <p>More fixes for the wxFloatBar, and it now works on wxGTK even better
1692 than wxMSW!  (The feat is accomplished by using the wxTB_DOCKABLE
1693 style flag instead of trying to float it ourselves.)</p>

1699 </ul>
1700 <p>Skipped a few version numbers so wxMSW, wxGTK and wxPython are all
1701 syncronized.</p>
1702 <p>wxImage.SetData now makes a copy of the image data before giving it to
1703 wxImage.  I mistakenly thought that wxImage would copy the data
1704 itself.</p>
1705 <p>Fixed wxMSW's notebook so the pages get their size set as they are
1706 being added.  This should remove the need for our
1707 wxNotebook.ResizeChildren hack.</p>
1708 <p>wxPanels now support AutoLayout, and wxNotebooks and wxSplitterWindows
1709 no longer tell their children to Layout() themselves.  This will
1710 probably only effect you if you have a wxWindow with AutoLayout inside
1711 a notebook or splitter.  If so, either change it to a wxPanel or add
1712 an EVT_SIZE handler that calls Layout().</p>
1713 <p>Fixed deadlock problem that happened when using threads.</p>
1714 <p>Added new HTML printing classes.</p>
1715 <p>Added wxWindow.GetHandle</p>
1716 <p>Apparently wxMouseEvent.Position has been deprecated in wxWindows as
1717 it is no longer available by default.  You can use GetPositionTuple
1718 (returning a tuple with x,y) instead, or GetPosition (returning a
1719 wxPoint.)</p>
1720 <p>Added wxPostEvent function that allows events to be posted and then
1721 processed later.  This is a thread-safe way to interact with the GUI
1722 thread from other threads.</p>
1723 <p>Added Clipboard and Drag-and-Drop classes.</p>
1724 <p>Added wxFontEnumerator.</p>
1725 <p>Many updates to wxMenu, wxMenuBar.</p>
1726 <p>wxPyEvent and wxPyCommandEvent derived classes now give you the actual
1727 Python object in the event handler instead of a new shadow.</p>
1728 <p>Added a Calendar widget from Lorne White to the library.</p>
1729 <p>Made some fixes to the wxFloatbar.  It still has some troubles on
1730 wxGTK...</p>
1731 <p>Added an MVC tree control from Bryn Keller to the library.</p>

1735 <ul class="simple">
1736 <li>12-Oct-1999</li>
1737 </ul>
1738 <p>This is a quick bug-fix release to take care of a few nasties that
1739 crept in at the last minute before 2.1.4 was called done.  No new
1740 major features.</p>

1744 <ul class="simple">
1745 <li>7-Oct-1999</li>
1746 </ul>
1747 <p>This release is NOT syncronized with a snapshot release of wxGTK or
1748 wxMSW.  For MSW this isn't much of a problem since you can get the
1749 binaries from the web site.  For other platforms you'll have to build
1750 wxGTK from CVS.  (See <a class="reference" href="http://web.ukonline.co.uk/julian.smart/wxwin/cvs.htm">http://web.ukonline.co.uk/julian.smart/wxwin/cvs.htm</a>)
1751 To get the same set of sources from CVS that I used, checkout using
1752 the wxPy-2-1-4 tag.</p>
1753 <p>Now back to what's new...</p>
1754 <p>Much more support for event-less callbacks and add-on modules.</p>
1755 <p>Created add-on module with wxOGL classes.</p>
1756 <p>Added wxWindow.GetChildren().  Be careful of this.  It returns a <em>copy</em>
1757 of the list of the window's children.  While you are using the list if
1758 anything changes in the real list (a child is deleted, etc.) then the
1759 list you are holding will suddenly have window references to garbage
1760 memory and your app will likely crash.  But if you are careful it works
1761 great!</p>
1762 <p>Added a bunch of new and missing methods to wxTreeCrtl.  The
1763 SortChildren method is now supported, but currently only for the
1764 default sort order.</p>
1765 <p>Added typemaps for wxSize, wxPoint, wxRealPoint, and wxRect that allow
1766 either the actual objects or Python sequence values to be used.  For
1767 example, the following are equivallent:</p>
1768 <pre class="literal-block">
1769 win = wxWindow(parent, size = wxSize(100, 100))
1770 win = wxWindow(parent, size = (100, 100))
1771 </pre>
1772 <p>Super-charged the wxHtml module.  You can now create your own tag
1773 handlers and also have access to the parser and cell classes.  There
1774 is a tag handler in the library at wxPython.lib.wxpTag that
1775 understands the WXP tag and is able to place wxPython windows on HTML
1776 pages.  See the demo for an example.</p>
1777 <p>A bunch of the methods of wxMenuBar were previously ifdef'd out for
1778 wxGTK.  Added them back in since the methods exist now.</p>
1779 <p>Wrapped the wxHtmlHelpController and related classes.</p>
1780 <p>Wrapped the C++ versions of wxSizer and friends.  The Python-only
1781 versions are still in the library, but deprecated.  (You will get a
1782 warning message if you try to use them, but the warning can be
1783 disabled.) The usage of the C++ versions is slightly different, and
1784 the functionality of wxBorderSizer is now part of wxBoxSizer.  I have
1785 added a few methods to wxSizer to try and make the transition as
1786 smooth as possible, I combined all Add methods into a single method
1787 that handles all cases, added an AddMany method, etc.  One step I did
1788 not take was to make the default value of flag in the Add method be
1789 wxGROW.  This would have made it more backward compatible, but less
1790 portable to and from wxWin C++ code.  Please see the docs and demo for
1791 further details.</p>
1792 <p>Added wxPyEvent and wxPyCommandEvent classes, derived from wxEvent and
1793 wxCommandEvent.  Each of them has SetPyData and GetPyData methods that
1794 accept or return a single Python object.  You can use these classes
1795 directly or derive from them to create your own types of event objects
1796 that can pass through the wxWindows event system without loosing their
1797 Python parts (as long as they are stored with SetPyData.)  Stay tuned
1798 for more info and examples in future releases.</p>
1799 <p>Added wxPython.lib.grids as an example of how to derive a new sizer
1800 from the C++ sizers.  In this module you will find wxGridSizer and
1801 wxFlexGridSizer.  wxGridSizer arrainges its items in a grid in which
1802 all the widths and heights are the same.  wxFlexgridSizer allows
1803 different widths and heights, and you can also specify rows and/or
1804 columns that are growable.  See the demo for a couple examples for how
1805 to use them.</p>
1806 <p>Added the wxValidator class, and created a class named wxPyValidator
1807 that should be used for the base class of any Python validators.  See
1808 the demo for an example.  Please note that you MUST implement a Clone
1809 method in your validator classes because of the way some things work
1810 in the underlying C++ library.  I did not add wxTextValidator because
1811 of some issues of how it transfers data to and from a wxString, which
1812 in wxPython is automatically translated to and from Python strings, so
1813 there would never be a concrete wxString that would hang around long
1814 enough for the validator to do its job.  On the other hand, it should
1815 be real easy to duplicate the functionality of wxTextValidator in a
1816 pure Python class derived from wxPyValidator.</p>
1817 <p>I've finally added a feature that has been on my list for close to two
1818 years!  Ever wondered what that zero is for when you create your app
1819 object?  Well now you can leave it out or explicitly set it to a true
1820 value.  This value now controls what is to be done with sys.stdout and
1821 sys.stderr.  A false value leaves them alone, and a true value sets
1822 them to an instance of wxPyOnDemandOutputWindow.  (On windows the
1823 default is true, on unix platforms the default is false.)  This class
1824 creates a frame containing a wxTextCtrl as soon as anything is written
1825 to sys.stdout or sys.stderr.  If you close the window it will come
1826 back again the next time something is written.  (You can call
1827 app.RestoreStdio to turn this off.)  If you would rather that the stdio be
1828 redirected to a file, you can provide a second parameter to your app
1829 object's constructor that is a filename.  If you want to use your own
1830 class instead of wxPyOnDemandOutputWindow you can either implement
1831 RedirectStdio() in you app class or change the value of
1832 wxApp.outputWindowClass like this:</p>
1833 <pre class="literal-block">
1834 class MyApp(wxApp):
1835     outputWindowClass = MyClass
1836
1837     def OnInit(self):
1838         frame = MyFrame()
1839         self.SetTopWindow(frame)
1840         return true
1841 </pre>
1842 <p>Please see the implementation of wxPyOnDemandOutputWindow and wxApp in
1843 wx.py for more details.  A few words of caution:  if you are running
1844 your app in a debugger, changing sys.stdout and sys.stderr is likely
1845 to really screw things up.</p>
1846 <p>Added wxCaret.  Unfortunately it's author has still not documented it
1847 in the wxWindows docs...</p>
1848 <p>Some new 3rd party contributions in wxPython.lib.  PyShell, in
1849 shell.py is an interesting implementaion of an interactive Python
1850 shell in wxWindows.  floatbar.py has a class derived from wxToolBar
1851 that can sense mouse drags and then reparent itself into another
1852 frame. Moving the new frame close to where it came from puts the tool
1853 bar back into the original parent.  (Unfortunately there is currently
1854 a bug in wxGTK's wxFrame.SetToolBar so the FloatBar has some
1855 problems...)</p>

1862 <p>This release is syncronized with release 2.1 snapshot 9 of wxWindows.</p>
1863 <p>Switched to using SWIG from CVS (see <a class="reference" href="http://swig.cs.uchicago.edu/cvs.html">http://swig.cs.uchicago.edu/cvs.html</a>)
1864 for some of the new features and such.  Also they have encorporated my
1865 patches so there is really no reason to stick with the current (very
1866 old) release...  This version of SWIG gives the following new
1867 features:</p>
1868 <blockquote>
1869 <ol class="arabic">
1870 <li><p class="first">Keyword arguments.  You no longer have to specify all the
1871 parameters with defaults to a method just to specify a
1872 non-default value on the end.  You can now do this instead:</p>
1873 <blockquote>
1874 <p>win = wxWindow(parent, -1, style = mystyle)</p>
1875 </blockquote>
1876 </li>
1877 <li><p class="first">There is now an an equivalence between Python's None and C++'s
1878 NULL.  This means that any methods that might return NULL will
1879 now return None and you can use none where wxWindows might be
1880 expecting NULL.  This makes things much more snake-ish.</p>
1881 </li>
1882 </ol>
1883 </blockquote>
1884 <p>There is a new build system based on a new Python program instead of
1885 raw makefiles.  Now wxPython builds are virtually the same on MSW or
1886 Unix systems.  See the end of this file for new build instructions and
1887 see distrib/build.py for more details.</p>
1888 <p>wxDC.Bilt now includes the useMask parameter, and has been split into
1889 two different versions.  wxDC.BlitXY is like what was there before and
1890 takes raw coordinants and sizes, and the new wxDC.Blit is for the new
1891 interface using wxPoints and a wxSize.</p>

1897 </ul>
1898 <p>Added the missing wxWindow.GetUpdateRegion() method.</p>
1899 <p>Made a new change in SWIG (update your patches everybody) that
1900 provides a fix for global shadow objects that get an exception in
1901 their __del__ when their extension module has already been deleted.
1902 It was only a 1 line change in .../SWIG/Modules/pycpp.cxx at about
1903 line 496 if you want to do it by hand.</p>
1904 <p>It is now possible to run through MainLoop more than once in any one
1905 process.  The cleanup that used to happen as MainLoop completed (and
1906 prevented it from running again) has been delayed until the wxc module
1907 is being unloaded by Python.</p>
1908 <p>I fixed a bunch of stuff in the C++ version of wxGrid so it wouldn't
1909 make wxPython look bad.</p>
1910 <p>wxWindow.PopupMenu() now takes a wxPoint instead of  x,y.  Added
1911 wxWindow.PopupMenuXY to be consistent with some other methods.</p>
1912 <p>Added wxGrid.SetEditInPlace and wxGrid.GetEditInPlace.</p>
1913 <p>You can now provide your own app.MainLoop method.  See
1914 wxPython/demo/demoMainLoop.py for an example and some explaination.</p>
1915 <p>Got the in-place-edit for the wxTreeCtrl fixed and added some demo
1916 code to show how to use it.</p>
1917 <p>Put the wxIcon constructor back in for GTK as it now has one that
1918 matches MSW's.</p>
1919 <p>Added wxGrid.GetCells</p>
1920 <p>Added wxSystemSettings static methods as functions with names like
1921 wxSystemSettings_GetSystemColour.</p>
1922 <p>Removed wxPyMenu since using menu callbacks have been deprecated in
1923 wxWindows.  Use wxMenu and events instead.</p>
1924 <dl class="docutils">
1925 <dt>Added alternate wxBitmap constructor (for MSW only) as</dt>
1926 <dd>wxBitmapFromData(data, type, width, height, depth = 1)</dd>
1927 </dl>
1928 <p>Added a helper function named wxPyTypeCast that can convert shadow
1929 objects of one type into shadow objects of another type.  (Like doing
1930 a down-cast.)  See the implementation in wx.py for some docs.</p>
1931 <p>Fixed wxImage GetData and SetData to properly use String objects for
1932 data transfer.</p>
1933 <p>Added access methods to wxGridEvent.</p>
1934 <p>New Makefile/Setup files supporting multiple dynamic extension modules
1935 for unix systems.</p>
1936 <p>Fixes for the wxGLCanvas demo to work around a strange bug in gtk.</p>
1937 <p>SWIG support routines now compiled separately instead of being bundled
1938 in wx.cpp.</p>

1945 <p>Fixed wxComboBox.SetSelection so that it actually sets the selected
1946 item.  (Actually just removed it from wxPython and let it default to
1947 wxChoice.SetSelection which was already doing the right thing.)</p>
1948 <p>Added the Printing Framework.</p>
1949 <p>Switched back to using the wxWindows DLL for the pre-built Win32
1950 version.  The problem was needing to reinitialize static class info
1951 data after loading each extension module.</p>
1952 <p>Lots of little tweaks and additions to reflect changes to various
1953 wxWindows classes.</p>
1954 <p>Fixed a bug with attaching objects to tree items.  Actually was a
1955 symptom of a larger problem with not obtaining the interpreter lock
1956 when doing any Py_DECREFs.</p>
1957 <p>wxSizer and friends.  Sizers are layout tools that manage a colection
1958 of windows and sizers.  Different types of sizers apply different
1959 types of layout algorithms.  You saw it here first!  These classes are
1960 not even in the wxWindows C++ library yet!</p>

2009 <p>Just a quickie update to fix the self-installer to be compatible with

2017 <p>Well obviously the numbering scheme has changed.  I did this to
2018 reflect the fact that this truly is the second major revision of
2019 wxPython, (well the third actually if you count the one I did for
2020 wxWindows 1.68 and then threw away...) and also that it is associated
2021 with the 2.0 version of wxWindows.</p>
2022 <p>I have finally started documenting wxPython.  There are several pages
2023 in the wxWindows documentation tree specifically about wxPython, and I
2024 have added notes within the class references about where and how wxPython
2025 diverges from wxWindows.</p>
2026 <p>Added wxWindow_FromHWND(hWnd) for wxMSW to construct a wxWindow from a
2027 window handle.  If you can get the window handle into the python code,
2028 it should just work...  More news on this later.</p>
2029 <p>Added wxImageList, wxToolTip.</p>
2030 <p>Re-enabled wxConfig.DeleteAll() since it is reportedly fixed for the
2031 wxRegConfig class.</p>
2032 <p>As usual, some bug fixes, tweaks, etc.</p>
2033 </div>
2034 <div class="section" id="what-s-new-in-0-5-3">
2035 <h1><a name="what-s-new-in-0-5-3">What's new in 0.5.3</a></h1>
2036 <ul class="simple">
2037 <li>30-Jan-1999</li>
2038 </ul>
2039 <p>Added wxSashWindow, wxSashEvent, wxLayoutAlgorithm, etc.</p>
2040 <p>Various cleanup, tweaks, minor additions, etc. to maintain
2041 compatibility with the current wxWindows.</p>
2042 </div>
2043 <div class="section" id="what-s-new-in-0-5-0">
2044 <h1><a name="what-s-new-in-0-5-0">What's new in 0.5.0</a></h1>
2045 <p>Changed the import semantics from <tt class="docutils literal"><span class="pre">&quot;from</span> <span class="pre">wxPython</span> <span class="pre">import</span> <span class="pre">*&quot;</span></tt> to
2046 <tt class="docutils literal"><span class="pre">&quot;from</span> <span class="pre">wxPython.wx</span> <span class="pre">import</span> <span class="pre">*&quot;</span></tt>  This is for people who are worried about
2047 namespace pollution, they can use &quot;from wxPython import wx&quot; and then
2048 prefix all the wxPython identifiers with &quot;wx.&quot;</p>
2049 <p>Added wxTaskbarIcon for wxMSW.</p>
2050 <p>Made the events work for wxGrid.</p>
2051 <p>Added wxConfig.</p>
2052 <p>Added wxMiniFrame for wxGTK.</p>
2053 <p>Changed many of the args and return values that were pointers to gdi
2054 objects to references to reflect changes in the wxWindows API.</p>
2055 <p>Other assorted fixes and additions.</p>

2062 <p>wxPython on wxGTK works!!!  Both dynamic and static on Linux and
2063 static on Solaris have been tested.  Many thanks go to Harm van der
2064 Heijden for his astute detective work on tracking down a nasty DECREF
2065 bug.  Okay so I have to confess that it was just a DSM (Dumb Stupid
2066 Mistake) on my part but it was nasty none the less because the
2067 behavior was so different on different platforms.</p>
2068 <p>The dynamicly loaded module on Solaris is still segfaulting, so it
2069 must have been a different issue all along...</p>

2071 <div class="section" id="what-s-new-in-0-4">

2076 <p>1. Worked on wxGTK compatibility.  It is partially working.  On a
2077 Solaris/Sparc box wxPython is working but only when it is statically
2078 linked with the Python interpreter.  When built as a dyamically loaded
2079 extension module, things start acting weirdly and it soon seg-faults.
2080 And on Linux both the statically linked and the dynamically linked
2081 version segfault shortly after starting up.</p>
