  13 <div class="section" id="id1">
  14 <h1><a name="id1">2.6.0.0</a></h1>
  15 <p>wxMSW: Fixed wx.TransientPopupWindow (and therefore wx.TipWindow) to
  16 auto-dismiss when the mouse is clicked outside of the popup like it is
  17 supposed to.</p>
  18 <p>wxMSW: Fixed bug #1167891 wx.Notebook display problem with wx.NB_MULTILINE.</p>
  19 <p>wxMSW: Fixed bad cliping of hidden windows inside of wx.StaticBox.</p>
  20 <p>wxGTK:  The configure flags for selecting GTK+ 1.2.x or 2.x has
  21 changed slightly.  It is now --with-gtk[=VERSION] where VERSION is
  22 either '1', '2' or 'any'.  The default is '2'.</p>
  23 <p>wx.stc.StyledTextCtrl: Added the following methods for alternate ways
  24 to set and fetch text from the document buffer.  They work similarly
  25 to the existing methods of the same name, except that they don't go
  26 through the same string/unicode &lt;--&gt; wxString conversions.  The &quot;Raw&quot;
  27 methods will do no conversions at all and in a unicode build of
  28 wxPython the strings will be in the utf-8 encoding and in an ansi
  29 build no assumption is made about the encoding.  The &quot;UTF8&quot; functions
  30 will attempt to always get/set utf-8 text, which it will always be
  31 able to do in a unicode build, and in an ansi build it will depend on
  32 the content of the utf-8 used being compatible with the current
  33 encoding, (you'll get an exception otherwise.)</p>

  70 </blockquote>
  71 <p>wx.stc.StyledTextCtrl:  Added the StyleSetFontEncoding(style, enc)
  72 method that allows you to set the encoding to be used by the font for
  73 a particular style.</p>
  74 <p>wxMac: Fixed wx.ComboBox to forward the EVT_CHAR, EVT_KEY_DOWN,
  75 EVT_KEY_UP and EVT_TEXT events from its embedded text control.</p>
  76 <p>wxMac: Corrected refresh bugs in wxGrid.</p>
  77 <dl>
  78 <dt>XRCed: Updated to version 0.1.5.</dt>
  79 <dd><ul class="first last simple">
  80 <li>Added wxWizard, wxWizardPageSimple (only from pull-down menu).</li>
  81 <li>Hide command for test window.</li>
  82 <li>Replacing classes works better.</li>
  83 <li>Added Locate tool.</li>
  84 </ul>

  87 </div>
  88 <div class="section" id="id2">
  89 <h1><a name="id2">2.5.5.1</a></h1>
  90 <p>wxMSW: Fixed bug #1022383, 'several ComboBoxes appear selected'</p>
  91 <p>wx.grid.Grid: Fixed bug #1163384.  Moved the code that handles
  92 activating the cell editors to a EVT_CHAR event handler.  This is done
  93 so the character inserted into the editor will be the &quot;cooked&quot; char
  94 value (including accented or composed keys) rather than the raw code
  95 provided by the EVT_KEY_DOWN event.</p>
  96 <p>Added orient parameter to wx.MDIParentFrame.Tile()</p>
  97 <p>wxMSW: wxTextCtrl with wx.TE_RICH2 style now uses RichEdit 4.1 if
  98 available.</p>
  99 <p>Added GetCount, GetCountRGB, and GetCountColour methods to
 100 wx.ImageHistogram.</p>
 101 <p>wxMSW: wx.Window.Refresh changed to explicitly refresh all children as
 102 well as the parent.  Previously it was implicitly done because parents
 103 did not clip their children by default.  Now that they always clip
 104 children then Refresh needed to be fixed to do a recursive refresh.
 105 This also fixes the Freeze/Thaw problems that some people had with
 106 2.5.4.1.</p>
 107 <p>wx.SplitterWindow: Send EVT_SPLITTER_SASH_POS_CHANGED only once after
 108 end of dragging and not after each CHANGING event (modified patch
 109 #1076226)</p>
 110 <p>wx.glcanvas.GLCanvas: applied patch fixing problems with X server
 111 crash when using nVidia cards (patch 1155132)</p>
 112 <dl>
 113 <dt>wx.lib.mixins.listctrl: Patches from Toni Brkic:</dt>
 114 <dd><ul class="first last simple">
 115 <li>Bugfix for TextEditMixin when the view can't be scrolled</li>
 116 <li>Enhancement for ListCtrlAutoWidthMixin, allowing it to manage
 117 the width of any column.</li>
 118 </ul>
 119 </dd>
 120 </dl>
 121 <p>wxMac: removal and reusing toolbar tools like the other platforms is
 122 now possible.</p>
 123 <p>wxMac: Correct radio tool selection after calling Realize a 2nd time.</p>
 124 <p>wxMSW: Applied patch #1166587, removes all flicker from wx.StaticBox</p>
 125 <p>Added wx.lib.foldpanelbar, Andrea Gavana's port of Jorgen Bodde's C++
 126 wxFoldPanelBar classes to Python.</p>
 127 <p>wxGTK: Applied patch #1173802, reimplementation of GtkFileChooser
 128 wxFileDialog by Mart Raudsepp.  Note that this new file dialog is only
 129 used on GTK2 &gt;= 2.4.  For earlier GTK2 versions and GTK1 then the
 130 older generic file dialog is used.</p>
 131 <p>wxMSW: fixes to static box borders calculations (finalizes patch
 132 #1166587)</p>
 133 <p>wx.Image: Use Python's buffer interface API for all image data and
 134 alpha Set/Get methods and the ImageFromData* constructors.  They all
 135 still copy the buffer except for SetDataBuffer and SetAlphaBuffer, but
 136 this gives more flexibility on where the data can come from.</p>
 137 <p>Added MDI support to XRC</p>
 138 <p>Added wx.animate module and a demo.  The wx.animate module provides a
 139 control that is able to display an animated GIF file.</p>
 140 <p>wx.lib.plot.py: Applied patch from Werner F. Bruhin that allows either
 141 vertical and/or horizontal gridlines.</p>
 142 <p>wxMSW: Extra space given for top border of wx.StaticBoxSizer so the
 143 upper line is not cliped when there is no label.</p>
 144 <p>wxMSW: Restored old behaviour of wx.StaticBox.SetBackgroundColour only
 145 affecting the label.</p>
 146 <p>wxMSW: Fixed missing EVT_RIGHT_DOWN and EVT_TREE_ITEM_RIGHT_CLICK
 147 events in a wx.TreeCtrl.</p>
 148 <p>Added wx.GetTopLevelWindows() function which returns a copy of the
 149 list of top-level windows that currently exist in the application.</p>
 150 <p>Updated docview library modules and sample apps from the ActiveGrid
 151 folks.</p>
 152 <p>Added the ActiveGrid IDE as a sample application.</p>
 153 </div>
 154 <div class="section" id="id3">
 155 <h1><a name="id3">2.5.4.1</a></h1>
 156 <p>wx.Sizer Add, Insert, and Prepend functions now return a reference to the
 157 wx.SizerItem that was added to the sizer, and the wx.SizerItem has a
 158 GetRect accessor to give the position of the item on the parent window.</p>
 159 <p>Added wx.Sizer.GetItem method which returns the wx.SizerItem for the given
 160 wx.Window, wx.Sizer or position index.</p>
 161 <p>wxMSW: wx.RadioButtons in the same group no longer have to be
 162 consecutive (there may be intervening controls). Without this fix, an
 163 out-of-sync assert is generated when clicking on a radio button and
 164 then calling GetValue().</p>
 165 <dl>
 166 <dt>Some XRC changes:</dt>
 167 <dd><ul class="first last simple">
 168 <li>Added 'icon' property to wxFrame and wxDialog</li>
 169 <li>No longer ignores menu bitmaps on non-MSW platforms</li>
 170 <li>Notebook page bitmaps are now supported</li>
 171 <li>added system colours and fonts support (based on patch #1038207)</li>
 172 </ul>
 173 </dd>
 174 </dl>
 175 <p>wxMSW: fix for [ 1052989 ] TextCtrl.SetBackgroundColour(wx.NullColour)
 176 bug.</p>
 177 <p>Added wx.PasswordEntryDialog analagous to wx.TextEntryDialog, allows
 178 detecting entering an empty string vs. cancel unlike the
 179 wx.GetPasswordFromUser dialog function.</p>
 180 <p>OGL patch from Shane Holloway:</p>
 181 <blockquote>
 182 <p>Two simple problems found in the new python ogl code.  First is
 183 the patch for _canvas.py.  Essentially:</p>
 184 <pre class="literal-block">
 185 dx = abs(dc.LogicalToDeviceX(x - self._firstDragX))
 186 dy = abs(dc.LogicalToDeviceY(y - self._firstDragY))
 187 </pre>
 188 <p>was incorrect because (x,y) and (self._firstDragX,
 189 self._firstDragY) are both already in Logical coordinates.
 190 Therefore the difference between the two is also in logical
 191 coordinates, and the conversion call is an error.  This bug
 192 surfaces when you have OGL on a scrollwin, and you are far from
 193 the origin of the canvas.</p>
 194 <p>The second change in _composit.py basically removes the assumption
 195 that the child is in both self._children and self._divisions.
 196 Causes many problems when it's not.  ;)</p>
 197 </blockquote>
 198 <p>Fixed GetSaveData and SetSaveData in wx.lib.multisash to not depend on
 199 the default way that class objectss are converted to strings.</p>
 200 <p>Fixed problem in StyledTextCtrl.Set[HV]ScrollBar that could leave the
 201 internal scrollbar visible.</p>
 202 <p>Added wx.StandardPaths which provides methods for determining standard
 203 system paths for each platform.</p>
 204 <p>wxMSW: The window background is now only erased by default if the
 205 background colour or background mode has been changed.  This better
 206 allows the default system themed behaviour to show through for
 207 uncustomized windows.  Explicit support added for using the correct
 208 theme texture for wx.Notebook pages and their children.</p>
 209 <p>wx.Image: Added support for alpha channels in interpolated and
 210 non-interpolated image rotation.  Added ConvertAlphaToMask helper
 211 method for turning shades of grey into shades of alpha and a colour.</p>
 212 <p>wxGTK2: Reimplemented DoDrawRotatedText() by way of a rotation of an
 213 alpha blended text bitmap.  It would be better if Pango could draw
 214 directly into an wxImage (as FreeType can,) but that is for later...</p>
 215 <p>Added wrappers and a demo for the wx.MediaCtrl class, which can play
 216 various forms of audio/video media using native codecs install on the
 217 system.  So far it is only implemented for Windows and OSX.</p>
 218 <p>wxGTK: Patch applied for Freeze()/Thaw() for wxTextCtrtl.</p>
 219 <p>Added &quot;gravity&quot; for splitter window (patch 1046105). Gravity is a
 220 floating-point factor between 0.0 and 1.0 which controls position of
 221 sash while resizing the wx.SplitterWindow.  The gravity specifies
 222 how much the left/top window will grow while resizing.</p>
 223 <p>wxMSW: wx.Slider's C++ implementation rewritten to be more
 224 maintainable and hopefully less buggy.  The position of the labels has
 225 also been changed in order to better comply with Microsoft's examples
 226 of how to use the control.</p>
 227 <p>wxMSW:  Fix wx.TreeCtrl to end label editing if the control loses
 228 focus (a slightly modified patch 1084592.)</p>
 229 <p>Added wx.EXEC_NODISABLE flag for wx.Execute, which will prevent all
 230 the app's windows being disabled while a synchronous child process is
 231 running.</p>
 232 <p>wxMSW: Much work to correct painting (or leaving transparent) of
 233 control backgrounds, properly using background themes on XP, etc.</p>
 234 <p>Fixed a circular reference problem with wx.Timer.  It will now
 235 completely cleanup after itself when the last reference to the timer
 236 is removed.  If you were previously using timer.Destroy() to cleanup
 237 your timers it will no longer work.  Instead you should hold a
 238 reference to the timer and then del the reference when you are
 239 finished with the timer.</p>
 240 <p>Updated to 1.3.24 of SWIG.  All of my big patches have been applied to
 241 the main SWIG source tree, but unfortunatly there were also some bugs
 242 added that affected the wxPython build and a few details in my
 243 original patch were changed/removed, so we are still not free of
 244 patches.  A new patch for SWIG is located in the wxPython/SWIG
 245 directory of the wxPython source tree.  SWIG 1.3.24 plus this patch
 246 should be used by anyone who is making custom modifications to
 247 wxPython's .i files, or building their own extension modules or
 248 etc. that need to interact with the wxPython swigged types.  For the
 249 morbidly curious, here are a few more details:</p>
 250 <blockquote>
 251 <ul class="simple">
 252 <li>Since it is now possible easily and simply share the SWIG type
 253 tables across modules I reverted to always using the stock SWIG
 254 runtime instead of my slightly hacked up version of it exported
 255 via the wxPython C API.</li>
 256 <li>The %name directive is now deprecated so I replaced most uses of
 257 it with a custom %Rename macro that uses %rename internally.
 258 These will evetually need to be replaced with a DocDecl macro
 259 when docstrings are added for those items.</li>
 260 <li>The &quot;this&quot; attribute of all SWIGged classes is no longer a
 261 string containing a &quot;swigified pointer&quot;, but rather a custom
 262 built-in type that holds the real C pointer to the object and
 263 the type info.  It can be converted to a string like the old
 264 value using str() or to the long integer value of the pointer
 265 using long().</li>
 266 </ul>
 267 </blockquote>
 268 <p>Added SetDefaultPyEncoding and GetDefaultPyEncoding functions which
 269 will set/get the encoding used by wxPython to convert string or
 270 unicode objects to/from wxString objects.  Previously the default
 271 Python encoding was always used, but unless the user had tweaked their
 272 sitecustomize.py file it is always &quot;ascii&quot;, which would result in
 273 errors if the strings contained character codes &gt;= 128.
 274 SetDefaultPyEncoding will now allow you to control which encoding will
 275 be used to do those conversions.  The default encoding is set to the
 276 value of <cite>locale.getdefaultlocale()[1]</cite> when wxPython is first
 277 imported.  Please see <a class="reference" href="http://www.alanwood.net/demos/charsetdiffs.html">http://www.alanwood.net/demos/charsetdiffs.html</a>
 278 for information on the differences between the common latin/roman
 279 encodings.</p>
 280 <p>Added wxStdDialogButtonSizer, which is a a special sizer that knows
 281 how to order and position standard buttons in order to conform to the
 282 current platform's standards.  You simply need to add each <cite>wx.Button</cite>
 283 to the sizer, and be sure to create the buttons using the standard
 284 ID's.  Then call <cite>Realize</cite> and the sizer will take care of the rest.</p>
 285 <p>wxMSW Toolbar: pass correct tool id (and not always -1) to the
 286 EVT_TOOL_RCLICKED handler</p>
 287 <p>wxGTK: Applied patch for combo box SELECTED events (no longer get
 288 lots of surplus events)</p>
 289 <p>wxGTK: Applied patch for proper menu highlight colour detection in
 290 wx.SystemSettings.</p>
 291 <p>wxGTK: Commited scrollbar patch #1093339 which sends lineup, linedown
 292 events based on intercepting the mouse down events.</p>
 293 <p>wxGTK: Applied patch #1102789 which solved conflicts between wxWidgets
 294 and GTK+'s context menu code.</p>
 295 <p>wxGTK: Applied patch #1100327 for correct feedback from DND actions
 296 (not all actions are allowed).</p>
 297 <p>Fixed memory leak in wxGrid::UpdateAttr[Rows][Or][Cols] (patch 1104355)</p>
 298 <p>For efficiency reasons, text controls no longer set the string for
 299 each text updated event, but rather query for the string value only
 300 when GetString is called from an event handler.</p>
 301 <p>Added wx.SL_INVERSE style which will cause wx.Slider to invert the min
 302 and max ends of the slider.</p>
 303 <p>Several patches applied, such as #1111174, #1110252 and others, that
 304 make the generic wx.TreeCtrl (used on wxGTK and wxMac) be more
 305 conistent with the wxMSW native wx.TreeCtrl.</p>
 306 <dl>
 307 <dt>XRCed:</dt>
 308 <dd><ul class="first last simple">
 309 <li>Edit-&gt;Locate command (Ctrl-L) for quick selection of items.
 310 Works with event-handling controls (buttons, text fields) but
 311 not with labels/sizers.</li>
 312 <li>Some improvements: relative paths for files supplied as command-
 313 line argument work correctly, notebook panels are highlighted
 314 better.</li>
 315 </ul>
 316 </dd>
 317 </dl>
 318 <p>wxMac: Fixed a long-standing issue where wxSlider controls with a
 319 hardcoded size would misplace their labels behind the slider control.</p>
 320 <p>wx.HtmlListBox fixed so calling RefreshLine(s) will cause the data for
 321 that line to be refetched from the overridden methods in the derived
 322 class.</p>
 323 <p>The default DoGetBestSize now includes the difference (if any) between
 324 the client size and total size of the window, (such as the size of
 325 borders.)  Code that sets the client size using the best size, or that
 326 added extra space to sizers to compensate for this bug may need to be
 327 changed.</p>
 328 <p>Can suppress themed notebook pages with the wxNB_NOPAGETHEME style or
 329 setting system option msw.notebook.themed-background to 0.</p>
 330 <p>wxSyledTextCtrl updated to use Scintilla 1.62.</p>
 331 <p>Can now set the msw.window.no-clip-children system option to 1 to
 332 eliminate weird refresh behaviour (delays between a window being
 333 erased and repainted, giving a ghostly gradual-redraw effect). May be
 334 a temporary 'fix' until properly fixed before 2.6.</p>
 335 <p>wxMac:  Toolbar is now more native looking with borderless toolbar
 336 buttons.</p>
 337 <p>wxMac: Switched wx.Bitmap to use newer Quartz object types and APIs
 338 internally.  This results in faster display and better alpha support.</p>
 339 <p>Added wx.DatePickerCtrl.</p>
 340 <p>wx.html.HtmlWindow now supports background images.</p>
 341 <p>Added wx.lib.gestures module from Daniel Pozmanter which supports
 342 using Mouse Gestures in an application.</p>
 343 <p>wxGTK2: ENTER and LEAVE mouse events are now sent for multi-line text
 344 controls.</p>
 345 <p>wxMSW:  &quot;Alt&quot; key (VK_MENU) now results in WXK_ALT keyboard event, not
 346 WXK_MENU</p>
 347 <p>Added modules from Peter Yared and Morgan Hua that implement the wx
 348 Doc/View framework in pure Python code.  See wx.lib.docview for the
 349 base implementation and wx.lib.pydocview for Python-specific
 350 extensions.  There are also a couple sample applications located in
 351 samples/docview.</p>
 352 <p>Added GetBitmap, GetIcon to wx.ImageList.</p>
 353 <p>wxGTK wx.Button.SetLabel no longer invalidates/resets the font.</p>
 354 <p>wx.Sizer.AddWindow, AddSizer, AddSpacer and etc. have now been
 355 undeprecated at the request of Riaan Booysen, the Boa Constructor team
 356 lead.  Boa needs them to help keep track of what kind of item is being
 357 managed by the sizer.  They are now just simple compatibility aliases
 358 for Add, and etc.</p>
 359 <p>The old C++ version of the OGL lib is no longer built by default.  Use
 360 the Python version in the wx.lib.ogl package instead.</p>
 361 <p>The wx.iewin module is no longer built by default.  You can use the
 362 wx.lib.iewin version instead.</p>
 363 <p>Fixed wx.BufferedPaintDC for scrolled windows to work whether the
 364 buffer is covering only the client area or the full virtual area of
 365 the scrolled window.  By default it will assume that only the client
 366 area is covered.  This is different than the old behavior so to
 367 indicate that the entire virtual area is covered simply add a
 368 style=wx.BUFFER_VIRTUAL_AREA parameter.</p>
 369 <p>wx.gizmos.TreeListCtrl:  Add support for the EVT_TREE_ITEM_GETTOOLTIP
 370 event.</p>
 371 <p>Added Resize, SetRGBRect, Size, and GetOrFindMaskColour methods to
 372 wx.Image.</p>
 373 <p>Added wx.Rect.IsEmpty</p>
 374 <dl>
 375 <dt>wxGTK:</dt>
 376 <dd><ul class="first last simple">
 377 <li>Corrected wx.ListBox selection handling</li>
 378 <li>Corrected default button size handling for different themes</li>
 379 <li>Corrected splitter sash size and look for different themes</li>
 380 <li>Fixed keyboard input for dead-keys</li>

 386 <h1><a name="id4">2.5.3.1</a></h1>
 387 <p>wxMac focus and border refreshes corrected.</p>
 388 <p>Updated internal PNG library.</p>
 389 <p>wxMac fix for metal appearance on wx.ToolBar.</p>
 390 <p>wx.grid.Grid fix allowing DoGetBestSize to be called before CreateGrid
 391 (which means that a min size doesn't need to be specified.)</p>
 392 <p>wxMac fix for not sending a native click to a control if it is not
 393 enabled (does an enable itself)</p>
 394 <p>Added wx.lib.ogl.DrawnShape, and fixed various little bugs in the new
 395 OGL.</p>
 396 <p>Added support to XRC and XRCed for the 3-state checkbox flags and also
 397 for wx.ToggleButton.  Updated the generic window styles supported by
 398 XRCed.</p>
 399 <p>It is now possible to create &quot;stock&quot; buttons.  Basically this means
 400 that you only have to provide one of the stock IDs (and either an
 401 empty label or a label that matches the stock label) when creating the
 402 button and wxWidgets will choose the stock label to go with it
 403 automatically.  Additionally on the platforms that have a native
 404 concept of a stock button (currently only GTK2) then the native stock
 405 button will be used.  For example, the following will result in a
 406 button with &quot;Cancel&quot; as the label and if run on wxGTK2 then there will
 407 also be an image of a red X:</p>
 408 <pre class="literal-block">
 409 b = wx.Button(parent, wx.ID_CANCEL)
 410 </pre>
 411 <p>Added wx.lib.ticker.Ticker class from Chris Mellon.</p>
 412 <p>Fix some incorrect clipping regions in wxSTC on wxGTK.</p>
 413 <p>Added wrapper for wx.grid.Grid.GetOrCreateCellAttr.</p>
 414 <p>Removed my copy of distutils from the wxPython source tree.  Now that
 415 I am no longer doing builds on Python 2.1 the newest distutils is no
 416 longer needed.  (There is still one small bug in Python 2.2 distutils
 417 on win32, but it is easily worked around.) This sovles the problem of
 418 incorrect builds on some systems where the system installed distutils
 419 has been patched to behave slightly differently, for example SuSE on
 420 x86_64 or Chandler's build.</p>
 421 <p>Updated to SWIG 1.3.22 (plus my patch.)  See wxPython/SWIG/README.txt
 422 in the source tree if you need to use SWIG when building your own copy
 423 of wxPython, or other extension modules that need to integrate with
 424 the wxPython modules.</p>
 425 <p>Added wx.Frame.RequestUserAttention which, if the platform suports it,
 426 will do something (such as flash the task bar item) to suggest to the
 427 user that they should look at that window.</p>
 428 <p>&quot;Fixed&quot; wx.grid.Grid.SetDefaultEditor and SetDefaultRenderer by making
 429 them register the editor or renderer for the &quot;string&quot; data type.</p>
 430 <p>Added depth param to wx.Image.ConvertToBitmap.</p>
 431 <p>Extended the wx.calendar.CalendarCtrl class with methods that get/set
 432 a Python datetime or date object.  (These will only work with Python
 433 2.3+) The methods are PySetDate, PyGetDate, PySetLowerDateLimit,
 434 PySetUpperDateLimit, PySetDateRange, PyGetLowerDateLimit, and
 435 PyGetUpperDateLimit.  Also, CalendarEvent was extended with PySetDate
 436 and PyGetDate methods.</p>
 437 <p>wxMSW: SetBackgroundColour on a wx.Choice or a wx.ComboBox will now
 438 also set the colour of the dropdown.</p>
 439 <p>wxMac: MessageDialog now supports wx.NO_DEFAULT style</p>
 440 <p>wxMSW: added AssociateHandle and DissociateHandle to wx.Window</p>
 441 <p>wxMac: fix for toolbar tooltips</p>
 442 <p>wx.Sizer.Show (and Hide) now take an optional parameter specifying if
 443 the item to be shown should be searched for recursivly in subsizers,
 444 and return a boolean value indicating if the item was found.</p>
 445 <p>wxMSW: fixed MaximizeEvent generation in wx.Frame</p>
 446 <p>wxMSW: fixed sending duplicate EVT_COMBOBOX events</p>
 447 <p>Smoother time estimation updates in wx.ProgressDialog (patch 992813)</p>
 448 <p>Made wx.Listbook events more consistent with wx.Notebook ones (patch
 449 1001271)</p>
 450 <p>Fixed rounding errors in variable status bar panes widths computation
 451 (patch 1030021)</p>
 452 <p>Added possibility to specify printer bin (patch 910272)</p>
 453 <p>wxMSW: fixed wx.ListCtrl's SetWindowStyleFlag() to not remove
 454 WS_VISIBLE; also refresh the control automatically (closes bug
 455 1019440)</p>
 456 <p>Added wx.Choicebook, yet another notebook-like control.</p>
 457 <p>wxMSW: Make radiobutton tab behaviour the same on MSW as in standard
 458 MSW app, i.e. tab into the activated, not necessarily the first radio
 459 button.</p>
 460 <p>Added limited support for wxEventLoop (you can't derive from a
 461 wx.PyEventLoop version yet...)  Updated and moved the sample showing
 462 how to replace the MainLoop to samples/mainloop/mainloop.py.</p>
 463 <p>The C++ xrc lib has been moved out of contrib and into the core, so it
 464 is always built by default.  wxPython's build has also changed
 465 accordingly and will build the xrc module as part of the core set of
 466 modules built by default.  If you were axplicitly using BUILD_XRC then
 467 it will no longer be recognized as a build option, otherwise you
 468 should notice no difference.</p>
 469 <p>wxMac: Fixed radio toolbar buttons to correctly untoggle the others
 470 when a new one is selected.</p>
 471 <p>wxMac: Fixed GetLineLength and GetLineText for MLTE text controls</p>
 472 <p>wxMac: wx.TaskBarIcon is implemented by allowing you to change the
 473 app's icon on the Dock and also specifying a menu that should be
 474 merged with the normal dock popup menu.  See the MigrationGuide for
 475 more details and a warning.</p>
 476 <p>Added wx.TopLevelWindow.IsActive() which tells you if the frame or
 477 dialog is or containts the active window with the keyboard focus.</p>
 478 <p>Added ability to create a font based on pixel size rather than point
 479 size via the FontFromPixelSize constructor.</p>
 480 <p>Updated the Scintilla used by StyledTextCtrl to version 1.61</p>
 481 <p>Improved image HitTest for TreeListCtrl.</p>
 482 <p>Added wx.App.IsMainLoopRunning.</p>
 483 <p>wxGTK: Make wxComboBox spit out a bit fewer surplus events when
 484 holding down the mouse button.</p>
 485 <p>wxGTK: Enable key based navigation through notebook tabs as in the
 486 native control with Left and right keys. Support for vetoing.</p>

 567 </div>
 568 <div class="section" id="id6">
 569 <h1><a name="id6">2.5.2.7</a></h1>
 570 <p>wx.ADJUST_MINSIZE is now the default behaviour for window items in
 571 sizers.  This means that the item's GetMinSize and/or GetBestSize will
 572 be called when calculating layout and the return value from that will
 573 be used for the minimum size used by the sizer.  The wx.FIXED_MINSIZE
 574 flag was added that will cause the sizer to use the old behaviour in
 575 that it will <em>not</em> call the window's methods to determine the new best
 576 size, instead the minsize that the window had when added to the sizer
 577 (or the size the window was created with) will always be used.  Please
 578 see the Sizers section in the Migration Guide for more details.</p>
 579 <p>Added new MaskedEditControl code from Will Sadkin.  The modules are
 580 now locaed in their own sub-package, wx.lib.masked.  Demos updated.</p>
 581 <p>The changes that implemented the incompatible wx.DC methods in 2.5.1.5
 582 have been reverted.  The wx.DC methods are now compatible with the 2.4
 583 implemetation.  In addition a set of renamed methods have been added
 584 that take wx.Point and/or wx.Size objects instead of individual
 585 parameters.</p>
 586 <p>Added wx.lib.mixins.listctrl.TextEditMixin, a mixin class that allows
 587 all columns of a wx.ListCtrl in report mode to be edited.</p>
 588 <p>Deprecated the wx.iewin module.</p>
 589 <p>Deprecated the wx.Sizer.AddWindow, AddSizer, AddSpacer methods as well
 590 as their Insert* and Prepend* counterparts.</p>
 591 <p>Added a generic StaticBitmap class in wx.lib.statbmp for the same
 592 reasons that stattext was created, so it could be mouse sensitive on
 593 all platforms like normal windows.  Also updated stattext.py and
 594 buttons.py to handle attribute (font &amp; colour) defaults and
 595 inheritance the new way.  If you have custom controls of your own you
 596 should review stattxt.py or one of the others to see how it is to be
 597 done.</p>
 598 <p>wx.InitAllImageHandlers is now an empty function that does nothing but
 599 exist for backwards compatibility.  The C++ version is now called
 600 automatically when wxPython is initialized.  Since all the handlers
 601 are included in the wxWidgets shared library anyway, this imposes only
 602 a very small amount of overhead and removes several unneccessary
 603 problems.</p>
 604 <p>Replaced wx/lib/pubsub.py with a version that uses weak references to
 605 track the subscribers, plus other fixes/additions.  Thanks go to
 606 Oliver Schoenborn and Robb Shecter.</p>
 607 <p>wxGTK now uses gtk_init_check so wxPython can raise an exception if
 608 there is no DISPLAY available or other initializaion problem.</p>
 609 <p>wx.GetKeyState now has an implementation for wxGTK and is able to
 610 detect the up/down or toggle state of modifier and toggle keys.</p>
 611 <p>The LC_NUMERIC locale is now reset back to &quot;C&quot; (compatibility) when
 612 running on wxGTK to work around the fact that GTK requires the locale
 613 to be set to the system settings but Python depends on LC_NUMERIC
 614 remaining compatible with &quot;C&quot;.</p>
 615 <p>Switched gizmos.TreeListCtrl to the newer version of the code from the
 616 wxCode project.</p>
 617 <p>OGL is dead! LONG LIVE OGL!  (Oops, sorry.  A bit of my dramatic side
 618 leaked out there...)  The wx.ogl module has been deprecated in favor
 619 of the new Python port of the OGL library located at wx.lib.ogl
 620 contributed by Pierre Hjälm.  This will hopefully greatly extend the
 621 life of OGL within wxPython by making it more easily maintainable and
 622 less prone to getting rusty as there seems to be less and less
 623 interest in maintaining the C++ version.  At this point there are just
 624 a couple minor known compatibility differences, please see the
 625 <a class="reference" href="MigrationGuide.html">MigrationGuide</a> file for details.</p>
 626 <p>EVT_STC_POSCHANGED has been removed as it has been deprecated in
 627 Scintilla for several releases now.</p>
 628 <p>All the Window and GDI (pen, bitmap, etc.) class constructors and also
 629 many toplevel functions and static methods will now check that a
 630 wx.App object has already been created and will raise a
 631 wx.PyNoAppError exception if not.</p>
 632 <p>Added more default args as needed to allow most window types to be
 633 constructed with only the parent window arg.  In some cases other args
 634 may be required for normal operation, but they can usually be set
 635 after construction.</p>
 636 <p>Removed the deprecated ErrorDialogs and PythonBitmaps modules.  If you
 637 were using these in your apps then please join wxPython-dev and assist
 638 with a more modern reimplementation.</p>
 639 <p>Added a new version (0.8.3) of FloatCanvas from Chris Barker.  It's now
 640 in a subpackage of wx.lib.</p>
 641 <p>It is now possible to change the tab traversal order of controls on a
 642 panel or dialog.  For details see the new MoveAfterInTabOrder and
 643 MoveBeforeInTabOrder methods of wx.Window.</p>
 644 <p>Applied (and heavily modified) a patch from Eugene
 645 &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
 646 edited and reloaded, all from within the demo.  You can switch back
 647 and forth between the default and your edited version, and any errors
 648 ocurring upon the reload are reported on the Demo tab.</p>
 649 <p>Added a menu item in the demo that will open a PyShell window that has
 650 the app and demo frame preloaded in the namespace.  This is another
 651 good way to explore and play with the objects in the currently running
 652 sample.  For example, load the Button sample and then do the following
 653 in the PyShell:</p>
 654 <pre class="literal-block">
 655 &gt;&gt;&gt; b = frame.demoPage.GetChildren()[0]
 656 &gt;&gt;&gt; for x in range(0, 500, 10):
 657 ...     b.Move((x, 50))
 658 ...     app.Yield(True)
 659 ...     wx.MilliSleep(10)
 660 </pre>
 661 <p>wxGTK: Applied wxNO_BORDER patch (#1098374) for text control and combo
 662 box.</p>

 666 <p>(See also the <a class="reference" href="MigrationGuide.html">MigrationGuide</a> file for details about some of the
 667 big changes that have happened in this release and how you should
 668 adapt your code.)</p>
 669 <p>The wxWindows project and library is now known as wxWidgets.  Please
 670 see <a class="reference" href="http://www.wxwindows.org/name.htm">http://www.wxwindows.org/name.htm</a> for more details.  This won't
 671 really affect wxPython all that much, other than the fact that the
 672 wxwindows.org domain name will be changing to wxwidgets.org, so mail
 673 list, CVS, and etc. addresses will be changing.  We're going to try
 674 and smooth the transition as much as possible, but I wanted you all to
 675 be aware of this change if you run into any issues.</p>
 676 <p>Many, many little fixes, changes and additions done as part of the move
 677 to wxWidgets 2.5 that I have forgotten about.</p>
 678 <p>Added wxMirrorDC.</p>
 679 <p>Added wxIconLocation</p>
 680 <p>Added Python wrappers and demos for the new wxVScrolledWindow,
 681 wxVListBox, and wxHtmlListBox classes.</p>
 682 <p>Added wrappers for wxBookCtrl and wxListbook.  wxNotebook now derives
 683 from wxBookCtrl.</p>
 684 <p>Added Gordon Williams' PyPlot module to the library, available as the
 685 wx.lib.plot module.</p>
 686 <p>I made a small but important change in the code that aquires the
 687 Python Global Interpreter Lock to try and prevent deadlocks that can
 688 happen when there are nested attempts to aquire the GIL.</p>
 689 <p>The RPMs will now install menu items on Mandrake Linux in
 690 Applications/Development/Tools for PyCrust, XRCed, etc.  The RPMs are
 691 also installing icons and <tt class="literal"><span class="pre">*.desktop</span></tt> items in the generic KDE and
 692 GNOME locations, but I don't know yet if they are resulting in menu
 693 items on non-Mandrake systems.  (It didn't automatically do it on my
 694 RH-9 build box but I didn't chase it very far...)  If you have ideas
 695 for how to improve the .spec file to work better and/or on more
 696 distros please send me a patch.</p>
 697 <p>The RPMs are now built on a fairly generic RH-9 box, and I have tested
 698 installing them also on my main Mandrake 9.2 box.</p>
 699 <p>There are some big changes in the OS X disk image.  The actual
 700 Installer package now <em>only</em> installs the wxMac dynlibs, wxPython
 701 extension modules and Python packages, and also the command-line tool
 702 scripts. The remaining items (demo, samples, and application bundles
 703 for the Demo, PyCrust and XRCed) are now top-level items in the disk
 704 image (.dmg file) that users can just drag and drop to wherever they
 705 want to put them.</p>
 706 <p>The wxWave class has been renamed to wxSound, and now has a slightly
 707 different API.</p>
 708 <p>Updated the AnalogClockWindow with many enhancements from E. A. Tacão.</p>
 709 <p>wxMac now has wx.ToggleButton!</p>
 710 <p>wx.stc.StyledTextCtrl has been updated to version 1.58 of Scintilla.</p>
 711 <p>To help with the wx.stc.StyledTextCtrl performance issues on wxMac
 712 I've added a SetUseAntiAliasing method (and GetUseAntiAliasing too)
 713 that will turn off the use of antialiased fonts in the wxSTC, allowing
 714 it to bypass the slow text measuring routines and use the fast and
 715 simple one instead.  By default the setting is turned off (on wxMac
 716 only.)  When run on OSX the Py* apps have a new item on the Options
 717 menu for controlling this setting if you would like to experiment with
 718 it.</p>
 719 <p>Updated wx.lib.calendar with many fixes and enhancements from Joerg
 720 &quot;Adi&quot; Sieker.</p>
 721 <p>Added wx.Display and wx.VideoMode.</p>
 722 <p>AppleEvents can be handled by overriding wx.App methods MacOpenFile,
 723 MacPrintFile, MacNewFile, and MacReopenApp.</p>
 724 <p>Added wx.PlatformInfo which is a tuple containing strings that
 725 describe the platform and build options of wxPython.  See the
 726 MigrationGuide for more details.</p>
 727 <p>Created a new extension module &quot;activex&quot; from Lindsay Mathieson's
 728 newest <a class="reference" href="http://members.optusnet.com.au/~blackpaw1/wxactivex.html">wxActiveX</a> class.  (The existing iewin module used an older
 729 version of this code, but only exposed the wxIEHtmlWin class.)  This
 730 new module will (in theory ;-) ) allow you to host arbitrary ActiveX
 731 controls in a wx.Window, <strong>without</strong> requiring the use of the win32com
 732 and other PyWin32 modules!  This should eliminate the cronic problems
 733 that have resulted from minor mismatches in how PyWin32 handles the
 734 GIL and tstate when making callbacks, etc.  The older iewin module
 735 will be left in this release as the new stuff is not fully backwards
 736 compatible, but you should migrate your code to the new IEHtmlWindow
 737 in wx.lib.iewin, so the old one can be eventually removed.
 738 Additionally, I've always considered that the wx.lib.activexwrapper
 739 module is an ugly hack that I only included in the lib because I
 740 couldn't figure out anything better.  Well now we have something that,
 741 if it isn't already, has the potential to be better.  So consider
 742 migrating away from using activexwrapper as well.  Please see the
 743 MigrationGuide for more details on using the new module.</p>
 744 <p>Floats are allowed again as function parameters where ints are expected.</p>
 745 </div>
 746 <div class="section" id="id9">
 747 <h1><a name="id9">2.4.2.4</a></h1>
 748 <p>Use wxSTC in the demo for displaying the soucre code of the samples.</p>
 749 <p>Lots of bug fixes and such from the wxWindows folks.</p>
 750 <p>Added wxPython.lib.newevent from Miki Tebeka.  Its usage is
 751 demonstrated in the Threads sample in the demo.</p>
 752 <p>Updates to wxMaskedEditCtrl.</p>
 753 <p>Added wxMaskedNumCtrl.</p>
 754 <p>Added Chris Barker's FloatCanvas.</p>
 755 </div>
 756 <div class="section" id="id10">
 757 <h1><a name="id10">2.4.1.2</a></h1>
 758 <p>Added wxScrolledPanel from Will Sadkin</p>
 759 <p>Added SetShape method to top level windows (e.g. wxFrame.)</p>
 760 <p>Changed wxSWIG to not generate Python code using apply, (since it will
 761 be deprecated in the future) wxSWIG will use <tt class="literal"><span class="pre">spam(*args,</span> <span class="pre">**kw)</span></tt> syntax
 762 instead.  Also changed the generated __repr__ methods to be a bit more
 763 informative.</p>
 764 <p>Made the version number information more robust and uh, informative.
 765 Also added asserts to check that the major.minor versions of wxPython
 766 and wxWindows match.</p>
 767 <p>Added the new wx &quot;renamer&quot; package that will dynamically import from
 768 the wxPython package and rename wxFooBar --&gt; FooBar.  That means that
 769 people can do imports without <tt class="literal"><span class="pre">&quot;import</span> <span class="pre">*&quot;</span></tt> and can use names like
 770 wx.Frame instead of wx.wxFrame.  This is phase 1 of a full transition
 771 to the new namespace.</p>
 772 <p>Updated Scintilla to 1.52.  I also changed it to use wxListCtrl
 773 instead of wxListBox for the AutoComplete window, added the ability to
 774 use custom bitmaps in the margin and in the AutoComplete windows, and
 775 worked out how to do proper clipping of child windows on wxGTK.</p>
 776 <p>Patrick O'Brien's PyCrust package has been renamed to Py and now
 777 includes several new tools.  As part of the change the location of the
 778 pacakge has changed as well, it is now accessible as &quot;from wxPython
 779 import py&quot; (or &quot;from wx import py&quot; using the new namespace.)  There
 780 are still some transition modules in the wxPython.lib.PyCrust package
 781 that will issue a warning and then import what is needed from the new
 782 package.  These will be removed in a future release.</p>
 783 <p>Added __nonzero__ method to wxTreeItemId, wxBitmap, wxImage, wxFont,
 784 and most other classes that have an Ok or IsOK method.  This allows
 785 code like &quot;if obj: ...&quot; to be the same as &quot;if obj.IsOk(): ...&quot;</p>
 786 <p>Toolbars on wxMac can now have controls on them.</p>
 787 <p>Added wxPython.lib.analogclock module based on samples that were
 788 passed back and forth on wxPython-users a while back.</p>
 789 <p>Added masked edit controls (wxPython.lib.maskededit) by Jeff Childers
 790 and Will Sadkin.  Updated wxTimeCtrl to use MaskedEdit.</p>
 791 <p>When the __class__ of a dead object is replaced with _wxPyDeadObject
 792 the __del__ of the original class is now called first.</p>
 793 <p>Added wxTreeListCtrl.  (Looks like a wxTreeCtrl embedded in a
 794 wxListCtrl, but actually is just giving multiple columns to a
 795 wxTreeCtrl.)</p>
 796 <p>Added wxFutureCall, a subclass of wxTimer that makes it easy to delay
 797 a call to any Python callable object.</p>
 798 <p>Added wxPy versions of wxPrintPreview, wxPreviewFrame, and
 799 wxPreviewControlBar so they can be derived from in Python and be able
 800 to override the C++ virtual methods.</p>
 801 <p>Simplified how the wxSizer methods are wrapped, changed the name of
 802 the &quot;option&quot; parameter to &quot;proportion&quot; to match the docs (&quot;option&quot; is
 803 still accepted for compatibility, but this will go away in a future
 804 release,) SetItemMinSize can now take a wxSize (or 2-tuple) parameter,
 805 and Spacers can be specified with a wxSize (or 2-tuple) parameter</p>
 806 <p>Added wxCursorFromBits.</p>
 807 </div>
 808 <div class="section" id="id11">
 809 <h1><a name="id11">2.4.0.7</a></h1>
 810 <p>Gave up on generating a warning upon the use of the old true/false or
 811 TRUE/FALSE values.</p>
 812 <p>Fixed wxGenericTreeCtrl (used on wxGTK and wxMac for wxTreeCtrl) so
 813 that it can successfully handle lots of nodes instead of overflowing
 814 when the virtual height of the widget overflowed a 16-bit value.</p>
 815 <p>Fixed the typemap that converts strings to wxColours to also accept
 816 unicode.</p>
 817 <p>Fixed problem where the wrong class name could sometimes be used for
 818 OOR.</p>
 819 <p>Fixed an interpreter lock problem in the __eq__ and __ne__ methods in
 820 wxSize and etc.</p>
 821 <p>Updated PyCrust to version 0.9</p>
 822 <p>Instead of always logging C++ assertions, added wxPYAPP_ASSERT_LOG
 823 flag to turn it on.  In most cases turning it into an exception (the
 824 default behavior) is enough.  See below in the 2.3.4.1 notes for more
 825 details.</p>

 838 </div>
 839 <div class="section" id="id12">
 840 <h1><a name="id12">2.4.0.4</a></h1>
 841 <p>Added missing wxRect methods</p>
 842 <p>Add OOR support for wxApp objects too.</p>
 843 <p>Added wxCursorFromImage, which works on wxMSW and wxGTK so far.</p>
 844 <p>All platforms now send EVT_DESTROY_WINDOW.  Be warned that at the time
 845 the event is sent the window is in the process of being deconstructed,
 846 and so calling some (most?) methods of the window itself may cause
 847 problems.</p>
 848 <p>Fixed SF Bug #689481, a method in the OGL wrappers was using the wrong
 849 return type.</p>
 850 <p>Fixed SF Bug #689958, an endless loop in printout.py.</p>
 851 <p>Added EVT_WINDOW_CREATE_ID and EVT_WINDOW_DESTROY_ID so these events
 852 can be associated with a specific window ID and more easily caught by
 853 the parent window.</p>
 854 <p>Fixed copy-paste error in wxListCtrl.GetFirstSelected.</p>
 855 <p>Added missing Init method (and an overloading wrapper) to wxLocale
 856 wrapper.</p>
 857 <p>Added a wxBitmap.SetMaskColour convenience method.</p>
 858 <p>Changed how the dynamic event tables (used for all Python wx classes,
 859 C++ wx classes typically use static event tables) are searched such
 860 that they behave from a Python perspective more like the static tables
 861 in C++.  Namely that if there are identical event bindings in a base
 862 Python class and a derived Python class that the one in the derived
 863 class will be found first and that if Skip is called that the one in
 864 the base class will still be found instead of skipping directly to the
 865 static stable in the C++ class.</p>
 866 <p>Switched to using True/False in the wxPython lib and demo instead of
 867 true/false or TRUE/FALSE to prepare for the new boolean type and
 868 constants being added to Python.  Added code to wx.py to test for the
 869 existence of the new constants and to create suitable values if not
 870 present.</p>
 871 <p>Added some static wxApp functions that help with integration with the
 872 Mac UI.  They are no-ops on other platforms so it doesn't hurt to
 873 always call them.  The functions are:</p>
 874 <blockquote>
 875 wxApp_GetMacDefaultEncodingIsPC
 876 wxApp_GetMacSupportPCMenuShortcuts
 877 wxApp_GetMacAboutMenuItemId
 878 wxApp_GetMacPreferencesMenuItemId
 879 wxApp_GetMacExitMenuItemId
 880 wxApp_GetMacHelpMenuTitleName
 881 wxApp_SetMacDefaultEncodingIsPC
 882 wxApp_SetMacSupportPCMenuShortcuts
 883 wxApp_SetMacAboutMenuItemId
 884 wxApp_SetMacPreferencesMenuItemId
 885 wxApp_SetMacExitMenuItemId
 886 wxApp_SetMacHelpMenuTitleName</blockquote>
 887 <p>Refactored, enhanced and added capabilities for the DrawXXXList
 888 functions, inspired by code from Chris Barker.</p>
 889 <p>The wxWindows .mo language catalog files are now installed in a
 890 subdirectory of the wxPython package dir on MSW since that platform
 891 doesn't have a standard place for them.</p>
 892 <p>Added missing deselect methods for wxGrid.</p>
 893 <p>Fixed typemaps for wxGridCellCoordsArray.</p>
 894 <p>Updated to the 0.9a version of PyCrust</p>

 916 <p>Show a couple new wxGrid features in the demo.</p>
 917 <p>Several bug fixes in wxWindows.</p>
 918 <p>Added wxHtmlFilter.</p>
 919 <p>wxASSERT and related C++ runtime diagnostics are now converted to
 920 Python exceptions.  When an assert happens a wxPyAssertionError
 921 (which derives from AssertionError) exception is created and when
 922 control returns back to the Python code that invoked the C++ API it
 923 will be raised.  The same exception restrictions are in place as
 924 before, namely that exceptions can't cross from one Python layer
 925 through C++ to another Python layer.  That simply means that if you
 926 want to catch wxPyAssertionError or any other exception that you need
 927 to do it before control returns to C++ at the end of your event
 928 handler or callback code.  There is some test code in demo/wxButton.py
 929 you can use to play with this new feature.</p>
 930 <p>Added some methods to wxApp (SetAssertMode and GetAssertMode) that let
 931 you control how C++ assertions are processed.  Valid modes are:
 932 wxPYAPP_ASSERT_SUPPRESS, wxPYAPP_ASSERT_EXCEPTION, and
 933 wxPYAPP_ASSERT_DIALOG.  Using _SUPPRESS will give you behavior like
 934 the old &quot;final&quot; builds and the assert will be ignored, _EXCEPTION is
 935 the new default described above, and _DIALOG is like the default in
 936 2.3.3.1 and prior &quot;hybrid&quot; builds.  You can also combine _EXCEPTION
 937 and _DIALOG if you wish, although I don't know why you would.</p>
 938 <p>You can now overload OnInitGui, OnExit and OnAssert in your classes
 939 derived from wxApp.</p>
 940 <p>Added GetSelectedCells, GetSelectionBlockTopLeft,
 941 GetSelectionBlockBottomRight, GetSelectedRows, GetSelectedCols nethods
 942 to wxGrid.</p>
 943 <p>Added Python == and != operators for some basic classes</p>
 944 <p>Fixed the Python wrappers for wxInputStream so they no longer block
 945 when reading from a wxProcess on wxGTK.  They now work more or less as
 946 they did before 2.3.3.1 but the dual meaning of eof() has been
 947 removed.  There is now a CanRead() method that lets you know if there
 948 is data waiting to be read from the pipe.</p>
 949 <p>Fixed method name clash in wxIEHtmlWin, renamed Refresh to RefreshPage.</p>
 950 <p>Added Throbber from Cliff Wells to the library and the demo.</p>
 951 <p>Windows installer prompts to uninstall old version first.</p>
 952 <p>Added wxPython.lib.evtmgr by Robb Shecter, which is an easier, more
 953 &quot;Pythonic&quot; and more OO method of registering handlers for wxWindows
 954 events using the Publish/Subscribe pattern.</p>
 955 <p>Added wxPython.lib.popupctl by Gerrit van Dyk which is a combobox-like
 956 gizmo for poping up arbitrary controls.  It is currently using
 957 wxDialog because of some issues with wxPopupWindow...</p>
 958 <p>Added wxPython.lib.gridmovers by Gerrit van Dyk which facilitates the
 959 dragging of columns and/or rows in a wxGrid.</p>
 960 <p>Added wxPython.lib.multisash by Gerrit van Dyk which is a nice
 961 implementation of allowing the user to split a window any number of
 962 times either horizontally or vertically, and to close the split off
 963 windows when desired.</p>
 964 <p>Added helpviewer tool that displays HTML books similarly to how MS
 965 HTMLHelp viewer does.  Changed how the wxPythonDocs tarball is built
 966 and added a script to launch the doc viewer.</p>
 967 </div>
 968 <div class="section" id="id17">
 969 <h1><a name="id17">2.3.3.1</a></h1>
 970 <p>Added wxSplashScreen.</p>
 971 <p>Added wxGenericDirCtrl.</p>
 972 <p>Added wxMultiChoiceDialog.</p>
 973 <p>The calltip window and autocomplete window in wxSTC will now use a
 974 wxPopupWindow if available on the platform (and functioning correctly)
 975 so they can extend beyond the client area of the STC if needed.</p>
 976 <p>Finished wrapping and providing typemaps for wxInputStream and also
 977 added the stream ctor and other methods for wxImage so images can now
 978 be loaded from any Python &quot;file-like&quot; object.</p>
 979 <p>Changed the img2py tool to use PNG instead of XPM for embedding image
 980 data in Python source code, and the generated code now uses streams to
 981 convert the image data to wxImage, wxBitmap, or wxIcon.</p>
 982 <p>Added the wxPython.lib.rcsizer module which contains RowColSizer.
 983 This sizer is based on code from Niki Spahiev and lets you specify a
 984 row and column for each item, as well as optional column or row
 985 spanning.  Cells with no item assigned to it are just left blank.
 986 Stretchable rows or columns are specified and work the same as in
 987 wxFlexGridSizer.</p>
 988 <p>Updated XRCed from Roman Rolinsky</p>
 989 <p>Added wxBufferedDC.</p>
 990 <p>Upgraded wxSTC from Scintilla 1.40 to Scintilla 1.45, and then again
 991 to version 1.47, and one more time to 1.48! &lt;wink&gt;</p>
 992 <dl>
 993 <dt>UNICODE!</dt>
 994 <dd><p class="first">wxWindows/wxPython can be compiled with unicode support enabled or
 995 disabled.  Previous to wxPython 2.3.3 non-unicode mode was always
 996 used.  Starting with 2.3.3 either mode is supported, but only if
 997 it is also available in wxWindows on the platform.  Currently
 998 wxWindows only supports unicode on MS Windows platforms, but with
 999 the recent release of GTK+ 2.0 it is only a matter of time until
1000 it can be done on wxGTK (Linux and other unixes) as well.</p>
1001 <p>Unicode works best on platforms in the NT branch of the Windows
1002 family tree (NT, win2k, XP) but it is now also possible to use the
1003 same unicode binaries on win95/98/ME platforms as well!  This is
1004 done by using a special library and DLL with the application
1005 called MSLU, (Microsoft Layer for Unicode).  It simply gets out of
1006 the way if the app is run on an NT box, otherwise if run on a
1007 win9x box it loads a special DLL that provides the unicode
1008 versions of the windows API.  So far I have not been able to get
1009 this to work perfectly on win9x.  Most things work fine but
1010 wxTaskBarIcon for example will cause a crash if used with the
1011 unicode build on win95.</p>
1012 <p class="last">So how do you use it?  It's very simple.  When unicode is enabled,
1013 then all functions and methods in wxPython that return a wxString
1014 from the C++ function will return a Python unicode object, and
1015 parameters to C++ functions/methods that expect a wxString can
1016 accept either a Python string or unicode object.  If a string
1017 object is passed then it will be decoded into unicode using the
1018 converter pointed to by wxConvCurrent, which will use the default
1019 system encoding.  If you need to use a string in some other
1020 encoding then you should convert it to unicode using the Python
1021 codecs first and then pass the unicode string to the wxPython
1022 method.</p>
1023 </dd>
1024 </dl>
1025 <p>Added wxListCtrlAutoWidthMixin from Erik Westra.</p>
1026 <p>Added wxIconBundle and wxTopLevelWindow.SetIcons.</p>
1027 <p>Added wxLocale and wxEncodingConverter.</p>
1028 <p>A little black magic...  When the C++ object (for a window or
1029 whatever) is deleted there is no way to force the Python shadow object
1030 to also be destroyed and clean up all references to it.  This leads to
1031 crashes if the shadow object tries to call a method with the old C++
1032 pointer.  The black magic I've done is to replace the __class__ in the
1033 Python instance object with a class that raises an exception whenever
1034 a method call (or other attribute access) is attempted.  This works
1035 for any class that is OOR aware.</p>
1036 <p>Added OOR support for wxGridCellRenderer, wxGridCellEditor,
1037 wxGridCellAttr, wxGridCellAttrProvider, wxGridTableBase and their
1038 derived classes.</p>
1039 <p>Added wxImage.GetDataBuffer which returns an in-place edit buffer of
1040 the image data.  (Patch #546009)</p>
1041 <p>Added a sample that shows how to embed wxPython in a wxWindows C++
1042 application.</p>
1043 <p>Added wxPyWindow, wxPyPanel and wxPyControl which are just like their
1044 wx counterparts except they allow some of the more common C++ virtual
1045 methods to be overridden in Python derived classes.  The methods
1046 supported are:</p>
1047 <blockquote>
1048 <p>DoMoveWindow
1049 DoSetSize
1050 DoSetClientSize
1051 DoSetVirtualSize
1052 DoGetSize
1053 DoGetClientSize
1054 DoGetPosition
1055 DoGetVirtualSize
1056 DoGetBestSize
1057 InitDialog
1058 TransferDataFromWindow
1059 TransferDataToWindow
1060 Validate
1061 AcceptsFocus
1062 AcceptsFocusFromKeyboard
1063 GetMaxSize
1064 AddChild
1065 RemoveChild</p>
1066 <p>If there are other methods that you think should be supported
1067 please let me know.</p>
1068 </blockquote>
1069 <p>Changed wxGenButton to derive from wxPyControl and overload
1070 DoGetBestSize and AcceptsFocus.</p>
1071 <p>Added wxArtProvider.</p>
1072 <p>Added wxCallAfter which is a helper function that registers a function
1073 (or any callable Python object) to be called once the next time there
1074 are no pending events.  This is useful for when you need to do
1075 something but it can't be done during the current event handler.  The
1076 implementation is very simple, see wxPython/wx.py.</p>
1077 <p>Fixed a boatload of reference leaks.</p>
1078 <p>Added a demo of using a sizer in a wxScrolledWindow, in effect
1079 creating a ScrolledPanel.</p>
1080 <p>Added a sample to the demo that shows how to use radio menu items, and
1081 other menu stuff.</p>
1082 <p>Added wxIEHtmlWin.  This is essentially the same as using IE with the
1083 ActiveXWrapper already in the library, but it is implemented all in
1084 C++ and therefore does not need any of the modules from win32all and
1085 so it is less fragile in the face of changes.</p>
1086 <p>Fixed the ActiveXWrapper problem.  Looks like when the win32com
1087 modules make a &quot;callback&quot; that they (incorrectly, IMHO) allocate a
1088 transient thread state structure.  Since wxPython is now saving
1089 tstates for it's own callbacks it ended up using garbage after
1090 win32com got rid of the temporary tstate...</p>
1091 <p>Added a generic static text control to wxPython.lib.stattext.  This is
1092 so things like Boa and PythonCard can have a static text that can
1093 respond to mouse events and etc.</p>
1094 <p>Changed the wxDateTime.Parse* methods to return an int that will be -1
1095 on failure, and the index where parsing stopped otherwise.</p>
1096 <p>Moved tools to be a Python package in wxPython.tools, added scripts to
1097 import and launch each tool.  This will let you import and use the
1098 tools in your own scripts or apps as needed.  On Linux and OS X the
1099 tool scripts are installed to {prefix}/bin so you should be able to
1100 easily launch them from the command line.  For example, PyCrust can be
1101 started with just the &quot;pycrust&quot; command.</p>
1102 <p>Added a sample to the demo that catches various key events and
1103 displays the details of the event.</p>
1104 <p>Added wxWizard, wxWizardPage, wxWizardPageSimple and wxPyWizardPage.</p>
1105 <p>Added wxXmlResourceHandler which allows you to create custom handlers
1106 for nonstandard class types in XRC resources.  See the demo for an
1107 example.</p>
1108 <p>Added wxPython.lib.mixins.rubberband module from Robb Shecter.</p>
1109 <p>Added wxTimeCtrl from Will Sadkin.</p>
1110 </div>
1111 <div class="section" id="id18">
1112 <h1><a name="id18">2.3.2.1</a></h1>
1113 <p>Changed (again) how the Python global interpreter lock is handled as
1114 well as the Python thread state.  This time it works on SMP machines
1115 without barfing and is also still compatible with Python debuggers.</p>
1116 <p>Added some patches from library contributors.</p>
1117 </div>
1118 <div class="section" id="id19">
1119 <h1><a name="id19">2.3.2</a></h1>
1120 <p>Added EVT_HELP, EVT_HELP_RANGE, EVT_DETAILED_HELP,
1121 EVT_DETAILED_HELP_RANGE, EVT_CONTEXT_MENU, wxHelpEvent,
1122 wxContextMenuEvent, wxContextHelp, wxContextHelpButton, wxTipWindow,
1123 and a demo to show them in action.</p>
1124 <p>Deprecated PyShell and PyShellWindow, added a snapshot of PyCrust (see
1125 <a class="reference" href="http://sourceforge.net/projects/pycrust/">http://sourceforge.net/projects/pycrust/</a>. )</p>
1126 <p>Added the new virtual list capabilities to wxListCtrl.</p>
1127 <p>Added a wxSTC style editor from Riaan Booysen to the sample apps.</p>
1128 <p>Added XRCed to the wxPython Tools directory, contributed by Roman
1129 Rolinsky.</p>
1130 <p>Added a new &quot;constructor&quot; to most of the window classes that calls the
1131 default C++ constructor, (the one with no parameters) and also added the
1132 corresponding  Create(...) method.  This allows you to do a 2-step
1133 creation of windows which is sometimes required for doing things such
1134 as setting extended style flags before the window is created, or for
1135 passing the object to the XRC resource system to be created from the
1136 resource.  The name of the new &quot;constructor&quot; is the original name of
1137 the class with a &quot;Pre&quot; in it.  For example, wxPreWindow, wxPreFrame,
1138 etc.</p>
1139 <p>Updated to version 1.40 of Scintilla and updated wxStyledTextCtrl
1140 accordingly.  While doing this update I dropped the wxLB_SORT style
1141 from the wxListBox created for the AutoComplete functionality.  This
1142 means that you will have to sort the keyword lists yourself, but you
1143 are free to do case sensitive or case insensitive sorts and set the
1144 wxSTC flag accordingly.</p>
1145 <p>Updated wxColumnSorterMixin to also be able to place sort icons on the
1146 column headers, and updated the wxListCtrl demo to show it off by
1147 using wxColumnSorterMixin.</p>
1148 <p>Added wxGenBitmapTextButton, TablePrint, etc. contribs from Lorne White.</p>
1149 <p>Added wxNativeFontInfo and wxFontMapper.</p>
1150 <p>Added pySketch to the samples.</p>
1151 <p>Significantly changed how the Python interpreter lock and thread state
1152 are managed, which should fix the problem of running on a
1153 multi-processor machine.</p>
1154 <p>Added wxPyLog so log targets can be created in Python to handle log
1155 messages however is wished.  See demo/Main.py for an example.</p>
1156 <p>Added wxFindReplaceDialog.</p>
1157 <p>The second phase of OOR is implemented for wxEvtHandler, wxSizer,
1158 wxShape and derived classes.  This means that functions and methods
1159 that return an object derived from wxEvtHandler that was originally
1160 created in Python, will return the original Python object (if it still
1161 exists) instead of letting SWIG wrap a new shadow object around the
1162 original C++ pointer.</p>
1163 <p>Added some optimization methods to wxDC: GetBoundingBox, DrawLineList,
1164 DrawPointList.</p>
1165 <p>Added a set of sophisticated Error Dialogs from Chris Fama.</p>
1166 <p>Added wxRightTextCtrl from Josu Oyanguren to wxPython.lib for aligning
1167 text in a wxTextCtrl to the right side.</p>
1168 <p>Added wxURLDataObject and an example showing drag and drop of URLs to
1169 and from web browsers.  It's still not 100% bullet-proof for all types
1170 of browsers, but it works for the majority of cases with the popular
1171 browsers on Windows.  On wxGTK it seems that only Netscape 4.x works,
1172 if anybody has any suggestions about this please bring it up on the
1173 wx-dev list.</p>
1174 <p>Added wxStopWatch.</p>
1175 <p>Added wxMimeTypesManager and wxFileType.</p>
1176 <p>Passing None for the handler parameter to one of the EVT_** functions
1177 will now Disconnect the event.</p>
1178 <p>Added wxPopupWindow and wxPopupTransientWindow.</p>
1179 <p>Added wxFileHistory.</p>
1180 <p>Added wxDynamicSashWindow, which allows you to endlessly split windows
1181 by dragging a little tab next to the scrollbars.  Added a demo to show
1182 this and also the ability of multiple wxStyledTextCtrls to share the
1183 same document.</p>
1184 <p>Added wxEditableListBox gizmo.</p>
1185 <p>Updated wxEditor with lots of enhancements from Steve Howell and Adam
1186 Feuer.</p>
1187 <p>Added the &quot;SplitTree gizmos&quot; which are a collection of classes that
1188 were designed to operate together and provide a tree control with
1189 additional columns for each item.  The classes are
1190 wxRemotelyScrolledTreeCtrl, wxTreeCompanionWindow,
1191 wxThinSplitterWindow, and wxSplitterScrolledWindow, some of which may
1192 also be useful by themselves.</p>
1193 <p>Added wxDllWidget from Vaclav Slavik which allows wx widgets derived
1194 from wxWindow to be loaded from a C++ .dll (or .so) and be used in a
1195 wxPython program, without the widget having to be SWIGged first.  The
1196 visible API of the widget is limited to wxWindow methods plus a
1197 SendCommand method, but it is still quite powerful.  See
1198 wxPython/contrib/dllwidget and wxPython/demo/dllwidget for more
1199 details.</p>

1203 <p>Added EVT_GRID_EDITOR_CREATED and wxGridEditorCreatedEvent so the user
1204 code can get access to the edit control when it is created, (to push
1205 on a custom event handler for example.)</p>
1206 <p>Added wxTextAttr class and SetStyle, SetDefaultStyle and
1207 GetDefaultStyle methods to wxTextCtrl.</p>
1208 <p>Added ability to use xml resource files.  Still need to add ability to
1209 subclass wxXmlResourceHandler, etc...</p>
1210 <p>Added wxGridAutoEditMixin to the mixins library package.</p>
1211 <p>Made ColourSelect be derived from wxButton.</p>
1212 <p>Fixed img2py to work correctly with Python 2.1.</p>
1213 <p>Added enhanced wxVTKRenderWindow by Prabhu Ramachandran</p>
1214 </div>
1215 <div class="section" id="id21">
1216 <h1><a name="id21">2.3.0</a></h1>
1217 <p>Removed initial startup dependency on the OpenGL DLLs so only the
1218 glcanvasc.pyd depends on them, (on wxMSW.)</p>
1219 <p>Changed wxFont, wxPen, wxBrush to not implicitly use the
1220 wxThe[Font|Pen|Brush]List objects behind the scenes, but to use normal
1221 ctor and dtors.</p>
1222 <p>Exposed the wxThe[Font|Pen|Brush]List to wxPython.</p>
1223 <p>Also added wxTheColourDatabase and added a library module (in the
1224 wxPython.lib.colourdb module) to load LOTS more colour names into the
1225 colour database.</p>
1226 <p>Added wxWakeUpMainThread, wxMutexGuiEnter, wxMutexGuiLeave,
1227 wxMutexGuiLocker and wxThread_IsMain to assist with dealing with GUI
1228 access from non-GUI threads.</p>
1229 <p>wxPyOnDemandOutputWindow is now (more) thread safe if non-GUI threads
1230 use print, sys.stdout.write, etc.</p>
1231 <p>Added CreateTextSizer and CreateButtonSizer to wxDialog</p>
1232 <p>Added wxPython/lib/infoframe.py from Chris Fama.  It contains a class
1233 that can be used in place of wxPyOnDemandOutputWindow.</p>
1234 <p>Added colourselect.py, imagebrowser.py and an updated calendar.py to
1235 wxPython/lib from Lorne White.</p>
1236 <p>Added patch to wxPoint_LIST_helper from Tim Hochberg that should make
1237 it gobs faster in certain situations.</p>
1238 <p>Added tools that will take an image file in a wx supported format and
1239 convert it to data embedded in a Python source file.  The image is
1240 converted to XPM format which is essentially a list of strings
1241 containing info about each pixel.  The image's transparency mask is
1242 included, if there is one, or a mask can be added if a mask colour is
1243 specified on the command line.  It is then pickled and optionally
1244 compressed and written to a Python source file along with functions to
1245 convert it to either a wxBitmap or a wxImage.  See
1246 wxPython/demo/images.py for examples, and wxPython/Tools/img2py.py for
1247 the implementation.</p>
1248 <p>Fixed wxStyledTextCtrl to be much faster on wxGTK.  There was some
1249 experimental code that got left in place that ended up causing way too
1250 many refreshes.</p>
1251 <p>A couple more hacks in my_distutils.py so wxPython can be built with
1252 the distutils that comes with Python 2.1.</p>
1253 <p>Added a ton of missing methods for wxPrintData.</p>
1254 <p>Switched to InnoSetup for MSW distributions.</p>
1255 <p>Added wxToggleButton.</p>
1256 <p>Fixed bug that prevented wxTreeCtrl.OnCompareItems from being called.</p>
1257 <dl>
1258 <dt>Added some methods to wxGrid:</dt>
1259 <dd>GetCellHighlightPenWidth
1260 GetCellHighlightROPenWidth
1261 SetCellHighlightPenWidth
1262 SetCellHighlightROPenWidth
1263 GetGridWindow
1264 GetGridRowLabelWindow
1265 GetGridColLabelWindow
1266 GetGridCornerLabelWindow</dd>
1267 </dl>
1268 <p>Added wxGetClientDisplayRect which on wxMSW returns a wxRect
1269 representing the area on screen not occupied by the taskbar and such.
1270 On other platforms it is equivallent to wxGetDisplaySize.</p>
1271 <dl>
1272 <dt>OOR:</dt>
1273 <dd><p class="first">Implemented the first phase of OOR (Original Object Return).  See
1274 the text in the demo for more details of what this means, but in a
1275 nutshell methods such as wxWindow.GetParent or FindWindowById will
1276 now return a shadow object of the proper type if it can.  By
1277 &quot;proper type&quot; I mean that if the wxWindow pointer returned from
1278 FindWindowById really points to a wxButton then the Python object
1279 constructed will be of a wxButtonPtr class instead of wxWindowPtr
1280 as before.  This should reduce or eliminiate the need for
1281 wxPyTypeCast.  (Woo Hoo!)  The objects returned are still not the
1282 original Python object, but that is the next step.  (Although it
1283 will probably only work on Python 2.1 and beyond because it will
1284 use weak references.)</p>
1285 <p class="last">This first phase of the OOR plan is fairly significant and has
1286 required a lot of changes all over wxPython, most of which should
1287 be transparent to you, however I'm not 100% sure that it didn't
1288 introduce any new bugs that are hiding somewhere and didn't get
1289 stomped on during my testing.  So please be sure to test everything
1290 thoroughly when you install this version and be sure to report any
1291 object-type related oddities to me.</p>
1292 </dd>
1293 </dl>
1294 <p>There is now a wxObject class that most other classes derive from like
1295 in C++, but the methods provided don't really match but are wxPython
1296 specific.  It could have been added long ago but OOR required it so it
1297 finally got done.</p>
1298 <p>Finally added wxPyLineShape.GetLineControlPoints, which has been on my
1299 list for a while.  The above OOR modification made this easier.</p>
1300 <p>Fixed the __cmp__ methods for wxPoint and others.</p>
1301 <p>Added wxWave.</p>
1302 <p>Added the wxPython.lib.mixins package to the library, it is where
1303 useful mix-in classes can be placed.  Currently there is one to help
1304 make the columns in a wxListCtrl sortable, and the MagicIMageList from
1305 Mike Fletcher.  If you have any custom code that can be factored out
1306 of existing classes into a mix-in that would be useful to others
1307 please send it to me for inclusion in this package.</p>
1308 <p>Added a few little sample applications to help newbies to get started
1309 by having smaller functional apps to play with.  They can be found in
1310 wxPython/samples.</p>

1312 <div class="section" id="id22">
1313 <h1><a name="id22">2.2.6</a></h1>
1314 <p>No changes happened in the Python wrappers for this release, only

1316 </div>
1317 <div class="section" id="id23">
1318 <h1><a name="id23">2.2.5</a></h1>
1319 <p>New typemaps for wxString when compiling for Python 2.0 and beyond
1320 that allow Unicode objects to be passed as well as String objects.  If
1321 a Unicode object is passed PyString_AsStringAndSize is used to convert
1322 it to a wxString using the default encoding.</p>
1323 <p>Fixed the generic buttons so tool tips work for them.</p>
1324 <p>Fixed a bug in the demo's tree control.</p>
1325 <p>Added a listbox to the listbox demo that shows how to find items with
1326 a matching prefix as keys are typed.</p>
1327 <p>Added code to the wxListCtrl demo to show how to get text from a
1328 column in report mode.</p>
1329 <p>Added code to the toolbar demo to clear the long help from the status
1330 bar after 2 seconds.</p>
1331 <p>Added wxJoystick.</p>
1332 <p>Fixed wxTimer so it can be used as described in the docs, either with
1333 a Notify method in a subclass, or sending an event to a wxEvtHandler
1334 object, (usually a window.)</p>
1335 <p>Added wxNotifyEvent.Allow()</p>
1336 <p>Fixed GOBS of reference leaks.</p>
1337 <p>Massive code changes and cleanup to allow wxPython to be split into
1338 multiple extension modules again.  A Python CObject is used to allow
1339 the &quot;export&quot; of SWIG functions and other common helper functions from
1340 the wxc module to other modules, even if they are in separate shared
1341 libraries.  Should also be usable from 3rd party code, just include
1342 wxPython/src/export.h</p>
1343 <p>Changed the default setup so the following are built as separate
1344 extension modules:  calendar, glcanvas, grid, html, ogl, stc, and
1345 utils.  Will probably add more later.</p>
1346 <p>Changed the wxPrinterDC to use the new constructor taking a
1347 wxPrintData object.  The old ctor is still there using the
1348 wxPrinterDC2 name.</p>
1349 <p>Added wxPython.lib.anchors.py from Riaan Booysen.  It contains a class
1350 that implements Delphi's Anchors with wxLayoutConstraints.</p>
1351 <p>Added wxPython.lib.fancytext from Timothy Hochberg.</p>
1352 <p>Changed the GenericButtons to send their event in idle time, so the
1353 mouse won't be captured when the event handler is called.</p>
1354 <p>Added wxPython.lib.rpcMixin from Greg Landrum, although it's not
1355 integrated with the demo yet.  It allows a wxPython GUI to be an
1356 XML-RPC server.</p>
1357 </div>
1358 <div class="section" id="new-in-2-2-2">
1359 <h1><a name="new-in-2-2-2">New in 2.2.2</a></h1>
1360 <p>Significantly changed how the wxStyledtextCtrl code that wraps
1361 Scintilla is implemented.  Most of it is now automatically generated
1362 from an interface definition file provided by Scintilla.  This means
1363 that it will be much easier to stay in sync with new Scintilla
1364 releases, but also means that some of the method and identifier names
1365 have changed.  See wxPython/demo/data/stc.h for a copy of the C++
1366 interface from which the Python interface is generated.  There is now
1367 some inline documentation in that file that should really help explain
1368 how things work.</p>
1369 <p>I am now using the Python Distutils to build wxPython and to make some
1370 of the distribution files.  (See <a class="reference" href="http://www.python.org/sigs/distutils-sig/">http://www.python.org/sigs/distutils-sig/</a>)
1371 This means no more messing with my kludgy build.py/Makefile hack,
1372 builds will be more consistent with other Python extensions that also
1373 use Distutils, and will hopefully make wxPython easier to build for
1374 platforms where there have been troubles before.  If you are building
1375 wxPython for Python 1.5.2 or for 1.6, then you will need to get and
1376 install version 1.0 of Distutils from the website above.  If you are
1377 using Python 2.0 then you already have it.</p>
1378 <p>Added wxInputStream and the wxFileSystem family of classes,
1379 contributed by Joerg Baumann.</p>
1380 <p>Added wxProcess and support for it to wxExecute.  wxProcess lets you
1381 get notified when an asyncronous child process terminates, and also to
1382 get input/output streams for the child process's stdout, stderr and
1383 stdin.</p>
1384 <p>Removed the old python sizers.</p>
1385 <p>Added __add__, __sub__ and __cmp__ (equality check only) for wxPoint
1386 and wxRealPoint.</p>
1387 <p>Changed the build to make one big extension module instead of one for
1388 the core and each contrib.  This allowed me to do away with the
1389 libwxPyHelpers.so on unix systems.</p>
1390 <p>Lots of little fixes here and there.</p>
1391 <p>Some hacks on wxGTK to try and make the AutoComplete listbox in the
1392 wxStyledTextCtrl to behave better.  It's still not as nice as on
1393 wxMSW, but at least it's a bit more usable now.</p>

1410 depressed state.</p>
1411 <p>Added wxTipProvider and friends.  See the demo for an example.</p>

1417 <p>WARNING: A while back I asked what should be done about the Magic
1418 Method Names.  (Methods that are automatically turned into event
1419 handlers by virtue of their name.)  The consensus was that it is more
1420 confusing to have them than to try and expand them to have greater
1421 coverage.  I am finally getting around to removing the code that
1422 generates the event binding.  This means that if you are using any of
1423 the following method names without a EVT_* call that you need to
1424 modify your code to add the EVT_* to hook the event to the method.</p>
1425 <blockquote>
1426 OnChar
1427 OnSize
1428 OnEraseBackground
1429 OnSysColourChanged
1430 OnInitDialog
1431 OnPaint
1432 OnIdle
1433 OnActivate
1434 OnMenuHighlight
1435 OnCloseWindow

1440 <h1><a name="new-in-2-1-15">New in 2.1.15</a></h1>
1441 <p>Fixed wxTreeCtrl.HitTest to return both the tree item as well as the
1442 flags that clairify where the click was in relation to the item.</p>
1443 <p>Fixed thread state problem in wxTreeCtrl.GetBoundingBox and
1444 GetSelections.</p>
1445 <p>Fixed some problems in OGL.  Also wxShape.SetClientData and
1446 .GetClientData can now deal with Python objects.</p>
1447 <p>Added wxListCtrl.SortItems and changed the demo to show how to use it.</p>
1448 <p>Plugged a memory leak.</p>
1449 <p>Wrapped the new wxGrid and friends.  The old wxGrid class is no longer
1450 available.  There are some incompatibilities, and unfortunately the
1451 new classes are not documented yet, (however the methods are more
1452 consistent with each other now so you may be able to guess pretty
1453 good...)</p>
1454 <p>Updated filebrowsebutton.py and calendar.py with changes from their
1455 authors.  There is now a FileBrowseButtonWithHistory class (what a
1456 mouthful!) and wxCalendar has printing support.</p>
1457 <p>Added ActiveXWrapper to the library, and some good demos of it too.
1458 It works great for embedding a COM (a.k.a OCX, a.k.a ActiveX) control
1459 in a window and calling its methods.  It actually creates a new class
1460 on the fly that derives from wxWindow, the COM CoClass and others
1461 needed to make it all work.  The resulting class can be instantiated
1462 just like wxWindow, used in sizers, etc.  It also responds to all COM
1463 method calls, properties, etc., and if the class or a mix-in has
1464 matching method names, then the COM events will be propogated back to
1465 them.</p>
1466 <p>Created a typemap that allows a string to be used for parameters
1467 expecting a wxColour type.  The string is either a colour name as
1468 defined in the wxColourDatabase, or a colour spec of the form
1469 &quot;#RRGGBB&quot;.  See the wxStyledTextCtrl demo for an example.</p>
1470 <p>I almost forgot to mention the wxStyledTextCtrl!  Yes, the
1471 wxStyledTextCtrl is finally in wxPython!!  (And the crowd goes
1472 wild...)   There's no documentaTion yet (the crowd boos and hisses...)
1473 but I've included a very readable source file in the
1474 wxPython/demo/data directory, a couple fairly good examples, and you
1475 can also refer to the Scintilla documentaion at
1476 <a class="reference" href="http://www.scintilla.org/ScintillaDoc.html">http://www.scintilla.org/ScintillaDoc.html</a> to help fill in the gaps
1477 until the docs are done.  (The croud murmers contentedly as the tool
1478 provider smiles convincingly and removes his flame-proof suit.)</p>

1481 <h1><a name="what-s-new-in-2-1-13">What's new in 2.1.13</a></h1>
1482 <p>Skipped a version number to match what has been released for wxGTK.</p>
1483 <p>Updated wxMVCTree and added a demo for it, also fixed layout on GTK
1484 and some flicker problems.</p>
1485 <p>Added a wrapper class for the Visualization ToolKit (or VTK) in the
1486 wxPython.lib.vtk module.  (<a class="reference" href="http://www.kitware.com/">http://www.kitware.com/</a>)</p>
1487 <p>Fixed wxTreeCtrl.SetItemImage and GetItemImage to recognise the new
1488 &quot;which&quot; parameter.</p>
1489 <p>Added wxPython.lib.spashscreen from Mike Fletcher.</p>
1490 <p>Added wxPython.lib.filebrowsebutton also from Mike Fletcher.</p>
1491 <p>Renamed wxTreeCtrl.GetParent to GetItemParent to avoid a name clash
1492 with wxWindow.GetParent.</p>
1493 <p>Added wxIntersectRect to compute the intersection of two wxRect's.
1494 It is used like this:</p>
1495 <blockquote>
1496 intersect = wxIntersectRect(rect1, rect2)</blockquote>
1497 <p>If r1 and r2 don't intersect then None is returned, otherwise the
1498 rectangle representing the intersection is returned.</p>
1499 <p>Some bug fixes for Clipboard and Drag-n-Drop.</p>
1500 <p>Rotated text!!!  WooHoo!  (See wxDC.DrawRotatedText())</p>
1501 <p>Added a set of Generic Buttons to the library.  These are simple
1502 window classes that look and act like native buttons, but you can have
1503 a bit more control over them.  The bezel width can be set in addition
1504 to colours, fonts, etc.  There is a ToggleButton as well as Bitmap
1505 versions too.  They should also serve as a good example of how to
1506 create your own classes derived from wxControl.</p>
1507 <p>The C++ wxToolBar classes have been redone, and so have the wxPython
1508 wrappers.  There have been slight modifications to some of the methods
1509 but shouldn't impact anybody too much.  I took the opportunity to add
1510 support for setting user data on each toolbar tool.  The new AddTool
1511 methods look like this:</p>
1512 <blockquote>
1513 <dl>
1514 <dt>def AddTool(ID,</dt>
1515 <dd>bitmap,
1516 pushedBitmap = wxNullBitmap,
1517 toggle = FALSE,
1518 clientData = NULL,
1519 shortHelpString = &quot;&quot;,
1520 longHelpString = &quot;&quot;)</dd>
1521 <dt>def AddSimpleTool(ID,</dt>
1522 <dd>bitmap,
1523 shortHelpString = &quot;&quot;,
1524 longHelpString = &quot;&quot;,
1525 toggle=FALSE)</dd>
1526 </dl>
1527 </blockquote>
1528 <p>There are also corresponding InsertTool and InsertSimpleTool methods
1529 that additionally take an integer position as the first parameter.</p>
1530 <p>Added a wrapper for the new PCX and TIFF ImageHandlers.</p>
1531 <p>wxRect now simulates attributes named left, right, top and bottom.</p>
1532 <p>Removed all non wx stuff from the glcanvas module since DA's PyOpenGL
1533 is better and compatible with the wxGLCanvas.  You can get it at
1534 <a class="reference" href="http://starship.python.net:9673/crew/da/Code/PyOpenGL">http://starship.python.net:9673/crew/da/Code/PyOpenGL</a>.</p>
1535 <p>Added some missing EVT functions.</p>
1536 <p>Added Dirk Holtwic's editor classes to the wxPython.lib.editor
1537 package.</p>
1538 <p>Changed all the &quot;LIST&quot; parameter names to &quot;choices&quot; to match the docs.</p>
1539 <p>More fixes for the wxFloatBar, and it now works on wxGTK even better
1540 than wxMSW!  (The feat is accomplished by using the wxTB_DOCKABLE
1541 style flag instead of trying to float it ourselves.)</p>

1544 <h1><a name="what-s-new-in-2-1-11">What's new in 2.1.11</a></h1>
1545 <p>Skipped a few version numbers so wxMSW, wxGTK and wxPython are all
1546 syncronized.</p>
1547 <p>wxImage.SetData now makes a copy of the image data before giving it to
1548 wxImage.  I mistakenly thought that wxImage would copy the data
1549 itself.</p>
1550 <p>Fixed wxMSW's notebook so the pages get their size set as they are
1551 being added.  This should remove the need for our
1552 wxNotebook.ResizeChildren hack.</p>
1553 <p>wxPanels now support AutoLayout, and wxNotebooks and wxSplitterWindows
1554 no longer tell their children to Layout() themselves.  This will
1555 probably only effect you if you have a wxWindow with AutoLayout inside
1556 a notebook or splitter.  If so, either change it to a wxPanel or add
1557 an EVT_SIZE handler that calls Layout().</p>
1558 <p>Fixed deadlock problem that happened when using threads.</p>
1559 <p>Added new HTML printing classes.</p>
1560 <p>Added wxWindow.GetHandle</p>
1561 <p>Apparently wxMouseEvent.Position has been deprecated in wxWindows as
1562 it is no longer available by default.  You can use GetPositionTuple
1563 (returning a tuple with x,y) instead, or GetPosition (returning a
1564 wxPoint.)</p>
1565 <p>Added wxPostEvent function that allows events to be posted and then
1566 processed later.  This is a thread-safe way to interact with the GUI
1567 thread from other threads.</p>
1568 <p>Added Clipboard and Drag-and-Drop classes.</p>
1569 <p>Added wxFontEnumerator.</p>
1570 <p>Many updates to wxMenu, wxMenuBar.</p>
1571 <p>wxPyEvent and wxPyCommandEvent derived classes now give you the actual
1572 Python object in the event handler instead of a new shadow.</p>
1573 <p>Added a Calendar widget from Lorne White to the library.</p>
1574 <p>Made some fixes to the wxFloatbar.  It still has some troubles on
1575 wxGTK...</p>

1586 <p>This release is NOT syncronized with a snapshot release of wxGTK or
1587 wxMSW.  For MSW this isn't much of a problem since you can get the
1588 binaries from the web site.  For other platforms you'll have to build
1589 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>)
1590 To get the same set of sources from CVS that I used, checkout using
1591 the wxPy-2-1-4 tag.</p>
1592 <p>Now back to what's new...</p>
1593 <p>Much more support for event-less callbacks and add-on modules.</p>
1594 <p>Created add-on module with wxOGL classes.</p>
1595 <p>Added wxWindow.GetChildren().  Be careful of this.  It returns a <em>copy</em>
1596 of the list of the window's children.  While you are using the list if
1597 anything changes in the real list (a child is deleted, etc.) then the
1598 list you are holding will suddenly have window references to garbage
1599 memory and your app will likely crash.  But if you are careful it works
1600 great!</p>
1601 <p>Added a bunch of new and missing methods to wxTreeCrtl.  The
1602 SortChildren method is now supported, but currently only for the
1603 default sort order.</p>
1604 <p>Added typemaps for wxSize, wxPoint, wxRealPoint, and wxRect that allow
1605 either the actual objects or Python sequence values to be used.  For
1606 example, the following are equivallent:</p>
1607 <blockquote>
1608 win = wxWindow(parent, size = wxSize(100, 100))
1609 win = wxWindow(parent, size = (100, 100))</blockquote>
1610 <p>Super-charged the wxHtml module.  You can now create your own tag
1611 handlers and also have access to the parser and cell classes.  There
1612 is a tag handler in the library at wxPython.lib.wxpTag that
1613 understands the WXP tag and is able to place wxPython windows on HTML
1614 pages.  See the demo for an example.</p>
1615 <p>A bunch of the methods of wxMenuBar were previously ifdef'd out for
1616 wxGTK.  Added them back in since the methods exist now.</p>
1617 <p>Wrapped the wxHtmlHelpController and related classes.</p>
1618 <p>Wrapped the C++ versions of wxSizer and friends.  The Python-only
1619 versions are still in the library, but deprecated.  (You will get a
1620 warning message if you try to use them, but the warning can be
1621 disabled.) The usage of the C++ versions is slightly different, and
1622 the functionality of wxBorderSizer is now part of wxBoxSizer.  I have
1623 added a few methods to wxSizer to try and make the transition as
1624 smooth as possible, I combined all Add methods into a single method
1625 that handles all cases, added an AddMany method, etc.  One step I did
1626 not take was to make the default value of flag in the Add method be
1627 wxGROW.  This would have made it more backward compatible, but less
1628 portable to and from wxWin C++ code.  Please see the docs and demo for
1629 further details.</p>
1630 <p>Added wxPyEvent and wxPyCommandEvent classes, derived from wxEvent and
1631 wxCommandEvent.  Each of them has SetPyData and GetPyData methods that
1632 accept or return a single Python object.  You can use these classes
1633 directly or derive from them to create your own types of event objects
1634 that can pass through the wxWindows event system without loosing their
1635 Python parts (as long as they are stored with SetPyData.)  Stay tuned
1636 for more info and examples in future releases.</p>
1637 <p>Added wxPython.lib.grids as an example of how to derive a new sizer
1638 from the C++ sizers.  In this module you will find wxGridSizer and
1639 wxFlexGridSizer.  wxGridSizer arrainges its items in a grid in which
1640 all the widths and heights are the same.  wxFlexgridSizer allows
1641 different widths and heights, and you can also specify rows and/or
1642 columns that are growable.  See the demo for a couple examples for how
1643 to use them.</p>
1644 <p>Added the wxValidator class, and created a class named wxPyValidator
1645 that should be used for the base class of any Python validators.  See
1646 the demo for an example.  Please note that you MUST implement a Clone
1647 method in your validator classes because of the way some things work
1648 in the underlying C++ library.  I did not add wxTextValidator because
1649 of some issues of how it transfers data to and from a wxString, which
1650 in wxPython is automatically translated to and from Python strings, so
1651 there would never be a concrete wxString that would hang around long
1652 enough for the validator to do its job.  On the other hand, it should
1653 be real easy to duplicate the functionality of wxTextValidator in a
1654 pure Python class derived from wxPyValidator.</p>
1655 <p>I've finally added a feature that has been on my list for close to two
1656 years!  Ever wondered what that zero is for when you create your app
1657 object?  Well now you can leave it out or explicitly set it to a true
1658 value.  This value now controls what is to be done with sys.stdout and
1659 sys.stderr.  A false value leaves them alone, and a true value sets
1660 them to an instance of wxPyOnDemandOutputWindow.  (On windows the
1661 default is true, on unix platforms the default is false.)  This class
1662 creates a frame containing a wxTextCtrl as soon as anything is written
1663 to sys.stdout or sys.stderr.  If you close the window it will come
1664 back again the next time something is written.  (You can call
1665 app.RestoreStdio to turn this off.)  If you would rather that the stdio be
1666 redirected to a file, you can provide a second parameter to your app
1667 object's constructor that is a filename.  If you want to use your own
1668 class instead of wxPyOnDemandOutputWindow you can either implement
1669 RedirectStdio() in you app class or change the value of
1670 wxApp.outputWindowClass like this:</p>
1671 <blockquote>
1672 <dl>
1673 <dt>class MyApp(wxApp):</dt>
1674 <dd><p class="first">outputWindowClass = MyClass</p>
1675 <dl class="last">
1676 <dt>def OnInit(self):</dt>
1677 <dd>frame = MyFrame()
1678 self.SetTopWindow(frame)
1679 return true</dd>
1680 </dl>
1681 </dd>
1682 </dl>
1683 </blockquote>
1684 <p>Please see the implementation of wxPyOnDemandOutputWindow and wxApp in
1685 wx.py for more details.  A few words of caution:  if you are running
1686 your app in a debugger, changing sys.stdout and sys.stderr is likely
1687 to really screw things up.</p>
1688 <p>Added wxCaret.  Unfortunately it's author has still not documented it
1689 in the wxWindows docs...</p>
1690 <p>Some new 3rd party contributions in wxPython.lib.  PyShell, in
1691 shell.py is an interesting implementaion of an interactive Python
1692 shell in wxWindows.  floatbar.py has a class derived from wxToolBar
1693 that can sense mouse drags and then reparent itself into another
1694 frame. Moving the new frame close to where it came from puts the tool
1695 bar back into the original parent.  (Unfortunately there is currently
1696 a bug in wxGTK's wxFrame.SetToolBar so the FloatBar has some
1697 problems...)</p>

1700 <h1><a name="what-s-new-in-2-1b3">What's new in 2.1b3</a></h1>
1701 <p>This release is syncronized with release 2.1 snapshot 9 of wxWindows.</p>
1702 <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>)
1703 for some of the new features and such.  Also they have encorporated my
1704 patches so there is really no reason to stick with the current (very
1705 old) release...  This version of SWIG gives the following new
1706 features:</p>
1707 <blockquote>
1708 <ol class="arabic">
1709 <li><p class="first">Keyword arguments.  You no longer have to specify all the
1710 parameters with defaults to a method just to specify a
1711 non-default value on the end.  You can now do this instead:</p>
1712 <blockquote>
1713 <p>win = wxWindow(parent, -1, style = mystyle)</p>
1714 </blockquote>
1715 </li>
1716 <li><p class="first">There is now an an equivalence between Python's None and C++'s
1717 NULL.  This means that any methods that might return NULL will
1718 now return None and you can use none where wxWindows might be
1719 expecting NULL.  This makes things much more snake-ish.</p>
1720 </li>
1721 </ol>
1722 </blockquote>
1723 <p>There is a new build system based on a new Python program instead of
1724 raw makefiles.  Now wxPython builds are virtually the same on MSW or
1725 Unix systems.  See the end of this file for new build instructions and
1726 see distrib/build.py for more details.</p>
1727 <p>wxDC.Bilt now includes the useMask parameter, and has been split into
1728 two different versions.  wxDC.BlitXY is like what was there before and
1729 takes raw coordinants and sizes, and the new wxDC.Blit is for the new
1730 interface using wxPoints and a wxSize.</p>
1731 </div>
1732 <div class="section" id="what-s-new-in-2-1b2">
1733 <h1><a name="what-s-new-in-2-1b2">What's new in 2.1b2</a></h1>
1734 <p>Added the missing wxWindow.GetUpdateRegion() method.</p>
1735 <p>Made a new change in SWIG (update your patches everybody) that
1736 provides a fix for global shadow objects that get an exception in
1737 their __del__ when their extension module has already been deleted.
1738 It was only a 1 line change in .../SWIG/Modules/pycpp.cxx at about
1739 line 496 if you want to do it by hand.</p>
1740 <p>It is now possible to run through MainLoop more than once in any one
1741 process.  The cleanup that used to happen as MainLoop completed (and
1742 prevented it from running again) has been delayed until the wxc module
1743 is being unloaded by Python.</p>
1744 <p>I fixed a bunch of stuff in the C++ version of wxGrid so it wouldn't
1745 make wxPython look bad.</p>
1746 <p>wxWindow.PopupMenu() now takes a wxPoint instead of  x,y.  Added
1747 wxWindow.PopupMenuXY to be consistent with some other methods.</p>
1748 <p>Added wxGrid.SetEditInPlace and wxGrid.GetEditInPlace.</p>
1749 <p>You can now provide your own app.MainLoop method.  See
1750 wxPython/demo/demoMainLoop.py for an example and some explaination.</p>
1751 <p>Got the in-place-edit for the wxTreeCtrl fixed and added some demo
1752 code to show how to use it.</p>
1753 <p>Put the wxIcon constructor back in for GTK as it now has one that
1754 matches MSW's.</p>
1755 <p>Added wxGrid.GetCells</p>
1756 <p>Added wxSystemSettings static methods as functions with names like
1757 wxSystemSettings_GetSystemColour.</p>
1758 <p>Removed wxPyMenu since using menu callbacks have been deprecated in
1759 wxWindows.  Use wxMenu and events instead.</p>
1760 <dl>
1761 <dt>Added alternate wxBitmap constructor (for MSW only) as</dt>
1762 <dd>wxBitmapFromData(data, type, width, height, depth = 1)</dd>
1763 </dl>
1764 <p>Added a helper function named wxPyTypeCast that can convert shadow
1765 objects of one type into shadow objects of another type.  (Like doing
1766 a down-cast.)  See the implementation in wx.py for some docs.</p>
1767 <p>Fixed wxImage GetData and SetData to properly use String objects for
1768 data transfer.</p>
1769 <p>Added access methods to wxGridEvent.</p>
1770 <p>New Makefile/Setup files supporting multiple dynamic extension modules
1771 for unix systems.</p>
1772 <p>Fixes for the wxGLCanvas demo to work around a strange bug in gtk.</p>
1773 <p>SWIG support routines now compiled separately instead of being bundled
1774 in wx.cpp.</p>

1777 <h1><a name="what-s-new-in-2-1b1">What's new in 2.1b1</a></h1>
1778 <p>Fixed wxComboBox.SetSelection so that it actually sets the selected
1779 item.  (Actually just removed it from wxPython and let it default to
1780 wxChoice.SetSelection which was already doing the right thing.)</p>
1781 <p>Added the Printing Framework.</p>
1782 <p>Switched back to using the wxWindows DLL for the pre-built Win32
1783 version.  The problem was needing to reinitialize static class info
1784 data after loading each extension module.</p>
1785 <p>Lots of little tweaks and additions to reflect changes to various
1786 wxWindows classes.</p>
1787 <p>Fixed a bug with attaching objects to tree items.  Actually was a
1788 symptom of a larger problem with not obtaining the interpreter lock
1789 when doing any Py_DECREFs.</p>
1790 <p>wxSizer and friends.  Sizers are layout tools that manage a colection
1791 of windows and sizers.  Different types of sizers apply different
1792 types of layout algorithms.  You saw it here first!  These classes are
1793 not even in the wxWindows C++ library yet!</p>

1798 <p>Bug fix for occassional GPF on Win32 systems upon termination of a
1799 wxPython application.</p>
1800 <p>Added wxListBox.GetSelections returning selections as a Tuple.</p>
1801 <p>Added a wxTreeItemData that is able to hold any Python object and be
1802 associated with items in a wxTreeCtrl.  Added test pytree.py to show
1803 this feature off.</p>
1804 <p>Added wxSafeYield function.</p>
1805 <p>OpenGL Canvas can be optionally compiled in to wxPython.</p>
1806 <p>Awesome new Demo Framework for showing off wxPython and for learning
1807 how it all works.</p>
1808 <p>The pre-built Win32 version is no longer distributing the wxWindows
1809 DLL.  It is statically linked with the wxWindows library instead.</p>
1810 <p>Added a couple missing items from the docs.</p>
1811 <p>Added wxImage, wxImageHandler, wxPNGHandler, wxJPEGHandler,
1812 wxGIFHandler and wxBMPHandler.</p>
1813 <p>Added new methods to wxTextCtrl.</p>
1814 <p>Fixed some problems with how SWIG was wrapping some wxTreeCtrl

1835 <p>Well obviously the numbering scheme has changed.  I did this to
1836 reflect the fact that this truly is the second major revision of
1837 wxPython, (well the third actually if you count the one I did for
1838 wxWindows 1.68 and then threw away...) and also that it is associated
1839 with the 2.0 version of wxWindows.</p>
1840 <p>I have finally started documenting wxPython.  There are several pages
1841 in the wxWindows documentation tree specifically about wxPython, and I
1842 have added notes within the class references about where and how wxPython
1843 diverges from wxWindows.</p>
1844 <p>Added wxWindow_FromHWND(hWnd) for wxMSW to construct a wxWindow from a
1845 window handle.  If you can get the window handle into the python code,
1846 it should just work...  More news on this later.</p>
1847 <p>Added wxImageList, wxToolTip.</p>
1848 <p>Re-enabled wxConfig.DeleteAll() since it is reportedly fixed for the
1849 wxRegConfig class.</p>

1874 <p>wxPython on wxGTK works!!!  Both dynamic and static on Linux and
1875 static on Solaris have been tested.  Many thanks go to Harm
1876 &lt;<a class="reference" href="mailto:H.v.d.Heijden&#64;phys.tue.nl">H.v.d.Heijden&#64;phys.tue.nl</a>&gt; for his astute detective work on tracking
1877 down a nasty DECREF bug.  Okay so I have to confess that it was just a
1878 DSM (Dumb Stupid Mistake) on my part but it was nasty none the less
1879 because the behavior was so different on different platforms.</p>
1880 <p>The dynamicly loaded module on Solaris is still segfaulting, so it
1881 must have been a different issue all along...</p>

1885 <p>1. Worked on wxGTK compatibility.  It is partially working.  On a
1886 Solaris/Sparc box wxPython is working but only when it is statically
1887 linked with the Python interpreter.  When built as a dyamically loaded
1888 extension module, things start acting weirdly and it soon seg-faults.
1889 And on Linux both the statically linked and the dynamically linked
1890 version segfault shortly after starting up.</p>
