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

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

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

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

 800 <p>Gave up on generating a warning upon the use of the old true/false or
 801 TRUE/FALSE values.</p>
 802 <p>Fixed wxGenericTreeCtrl (used on wxGTK and wxMac for wxTreeCtrl) so
 803 that it can successfully handle lots of nodes instead of overflowing
 804 when the virtual height of the widget overflowed a 16-bit value.</p>
 805 <p>Fixed the typemap that converts strings to wxColours to also accept
 806 unicode.</p>
 807 <p>Fixed problem where the wrong class name could sometimes be used for
 808 OOR.</p>
 809 <p>Fixed an interpreter lock problem in the __eq__ and __ne__ methods in
 810 wxSize and etc.</p>
 811 <p>Updated PyCrust to version 0.9</p>
 812 <p>Instead of always logging C++ assertions, added wxPYAPP_ASSERT_LOG
 813 flag to turn it on.  In most cases turning it into an exception (the
 814 default behavior) is enough.  See below in the 2.3.4.1 notes for more
 815 details.</p>

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

 904 <h1><a name="id16">2.3.4.1</a></h1>
 905 <p>Updated XRCed and wxTimeCtrl contribs.</p>
 906 <p>Show a couple new wxGrid features in the demo.</p>
 907 <p>Several bug fixes in wxWindows.</p>
 908 <p>Added wxHtmlFilter.</p>
 909 <p>wxASSERT and related C++ runtime diagnostics are now converted to
 910 Python exceptions.  When an assert happens a wxPyAssertionError
 911 (which derives from AssertionError) exception is created and when
 912 control returns back to the Python code that invoked the C++ API it
 913 will be raised.  The same exception restrictions are in place as
 914 before, namely that exceptions can't cross from one Python layer
 915 through C++ to another Python layer.  That simply means that if you
 916 want to catch wxPyAssertionError or any other exception that you need
 917 to do it before control returns to C++ at the end of your event
 918 handler or callback code.  There is some test code in demo/wxButton.py
 919 you can use to play with this new feature.</p>
 920 <p>Added some methods to wxApp (SetAssertMode and GetAssertMode) that let
 921 you control how C++ assertions are processed.  Valid modes are:
 922 wxPYAPP_ASSERT_SUPPRESS, wxPYAPP_ASSERT_EXCEPTION, and
 923 wxPYAPP_ASSERT_DIALOG.  Using _SUPPRESS will give you behavior like
 924 the old &quot;final&quot; builds and the assert will be ignored, _EXCEPTION is
 925 the new default described above, and _DIALOG is like the default in
 926 2.3.3.1 and prior &quot;hybrid&quot; builds.  You can also combine _EXCEPTION
 927 and _DIALOG if you wish, although I don't know why you would.</p>
 928 <p>You can now overload OnInitGui, OnExit and OnAssert in your classes
 929 derived from wxApp.</p>
 930 <p>Added GetSelectedCells, GetSelectionBlockTopLeft,
 931 GetSelectionBlockBottomRight, GetSelectedRows, GetSelectedCols nethods
 932 to wxGrid.</p>
 933 <p>Added Python == and != operators for some basic classes</p>
 934 <p>Fixed the Python wrappers for wxInputStream so they no longer block
 935 when reading from a wxProcess on wxGTK.  They now work more or less as
 936 they did before 2.3.3.1 but the dual meaning of eof() has been
 937 removed.  There is now a CanRead() method that lets you know if there
 938 is data waiting to be read from the pipe.</p>
 939 <p>Fixed method name clash in wxIEHtmlWin, renamed Refresh to RefreshPage.</p>
 940 <p>Added Throbber from Cliff Wells to the library and the demo.</p>
 941 <p>Windows installer prompts to uninstall old version first.</p>
 942 <p>Added wxPython.lib.evtmgr by Robb Shecter, which is an easier, more
 943 &quot;Pythonic&quot; and more OO method of registering handlers for wxWindows
 944 events using the Publish/Subscribe pattern.</p>
 945 <p>Added wxPython.lib.popupctl by Gerrit van Dyk which is a combobox-like
 946 gizmo for poping up arbitrary controls.  It is currently using
 947 wxDialog because of some issues with wxPopupWindow...</p>
 948 <p>Added wxPython.lib.gridmovers by Gerrit van Dyk which facilitates the
 949 dragging of columns and/or rows in a wxGrid.</p>
 950 <p>Added wxPython.lib.multisash by Gerrit van Dyk which is a nice
 951 implementation of allowing the user to split a window any number of
 952 times either horizontally or vertically, and to close the split off
 953 windows when desired.</p>
 954 <p>Added helpviewer tool that displays HTML books similarly to how MS
 955 HTMLHelp viewer does.  Changed how the wxPythonDocs tarball is built
 956 and added a script to launch the doc viewer.</p>
 957 </div>
 958 <div class="section" id="id17">
 959 <h1><a name="id17">2.3.3.1</a></h1>
 960 <p>Added wxSplashScreen.</p>
 961 <p>Added wxGenericDirCtrl.</p>
 962 <p>Added wxMultiChoiceDialog.</p>
 963 <p>The calltip window and autocomplete window in wxSTC will now use a
 964 wxPopupWindow if available on the platform (and functioning correctly)
 965 so they can extend beyond the client area of the STC if needed.</p>
 966 <p>Finished wrapping and providing typemaps for wxInputStream and also
 967 added the stream ctor and other methods for wxImage so images can now
 968 be loaded from any Python &quot;file-like&quot; object.</p>
 969 <p>Changed the img2py tool to use PNG instead of XPM for embedding image
 970 data in Python source code, and the generated code now uses streams to
 971 convert the image data to wxImage, wxBitmap, or wxIcon.</p>
 972 <p>Added the wxPython.lib.rcsizer module which contains RowColSizer.
 973 This sizer is based on code from Niki Spahiev and lets you specify a
 974 row and column for each item, as well as optional column or row
 975 spanning.  Cells with no item assigned to it are just left blank.
 976 Stretchable rows or columns are specified and work the same as in
 977 wxFlexGridSizer.</p>
 978 <p>Updated XRCed from Roman Rolinsky</p>
 979 <p>Added wxBufferedDC.</p>
 980 <p>Upgraded wxSTC from Scintilla 1.40 to Scintilla 1.45, and then again
 981 to version 1.47, and one more time to 1.48! &lt;wink&gt;</p>
 982 <dl>
 983 <dt>UNICODE!</dt>
 984 <dd><p class="first">wxWindows/wxPython can be compiled with unicode support enabled or
 985 disabled.  Previous to wxPython 2.3.3 non-unicode mode was always
 986 used.  Starting with 2.3.3 either mode is supported, but only if
 987 it is also available in wxWindows on the platform.  Currently
 988 wxWindows only supports unicode on MS Windows platforms, but with
 989 the recent release of GTK+ 2.0 it is only a matter of time until
 990 it can be done on wxGTK (Linux and other unixes) as well.</p>
 991 <p>Unicode works best on platforms in the NT branch of the Windows
 992 family tree (NT, win2k, XP) but it is now also possible to use the
 993 same unicode binaries on win95/98/ME platforms as well!  This is
 994 done by using a special library and DLL with the application
 995 called MSLU, (Microsoft Layer for Unicode).  It simply gets out of
 996 the way if the app is run on an NT box, otherwise if run on a
 997 win9x box it loads a special DLL that provides the unicode
 998 versions of the windows API.  So far I have not been able to get
 999 this to work perfectly on win9x.  Most things work fine but
1000 wxTaskBarIcon for example will cause a crash if used with the
1001 unicode build on win95.</p>
1002 <p class="last">So how do you use it?  It's very simple.  When unicode is enabled,
1003 then all functions and methods in wxPython that return a wxString
1004 from the C++ function will return a Python unicode object, and
1005 parameters to C++ functions/methods that expect a wxString can
1006 accept either a Python string or unicode object.  If a string
1007 object is passed then it will be decoded into unicode using the
1008 converter pointed to by wxConvCurrent, which will use the default
1009 system encoding.  If you need to use a string in some other
1010 encoding then you should convert it to unicode using the Python
1011 codecs first and then pass the unicode string to the wxPython
1012 method.</p>
1013 </dd>
1014 </dl>
1015 <p>Added wxListCtrlAutoWidthMixin from Erik Westra.</p>
1016 <p>Added wxIconBundle and wxTopLevelWindow.SetIcons.</p>
1017 <p>Added wxLocale and wxEncodingConverter.</p>
1018 <p>A little black magic...  When the C++ object (for a window or
1019 whatever) is deleted there is no way to force the Python shadow object
1020 to also be destroyed and clean up all references to it.  This leads to
1021 crashes if the shadow object tries to call a method with the old C++
1022 pointer.  The black magic I've done is to replace the __class__ in the
1023 Python instance object with a class that raises an exception whenever
1024 a method call (or other attribute access) is attempted.  This works
1025 for any class that is OOR aware.</p>
1026 <p>Added OOR support for wxGridCellRenderer, wxGridCellEditor,
1027 wxGridCellAttr, wxGridCellAttrProvider, wxGridTableBase and their
1028 derived classes.</p>
1029 <p>Added wxImage.GetDataBuffer which returns an in-place edit buffer of
1030 the image data.  (Patch #546009)</p>
1031 <p>Added a sample that shows how to embed wxPython in a wxWindows C++
1032 application.</p>
1033 <p>Added wxPyWindow, wxPyPanel and wxPyControl which are just like their
1034 wx counterparts except they allow some of the more common C++ virtual
1035 methods to be overridden in Python derived classes.  The methods
1036 supported are:</p>
1037 <blockquote>
1038 <p>DoMoveWindow
1039 DoSetSize
1040 DoSetClientSize
1041 DoSetVirtualSize
1042 DoGetSize
1043 DoGetClientSize
1044 DoGetPosition
1045 DoGetVirtualSize
1046 DoGetBestSize
1047 InitDialog
1048 TransferDataFromWindow
1049 TransferDataToWindow
1050 Validate
1051 AcceptsFocus
1052 AcceptsFocusFromKeyboard
1053 GetMaxSize
1054 AddChild
1055 RemoveChild</p>
1056 <p>If there are other methods that you think should be supported
1057 please let me know.</p>
1058 </blockquote>
1059 <p>Changed wxGenButton to derive from wxPyControl and overload
1060 DoGetBestSize and AcceptsFocus.</p>
1061 <p>Added wxArtProvider.</p>
1062 <p>Added wxCallAfter which is a helper function that registers a function
1063 (or any callable Python object) to be called once the next time there
1064 are no pending events.  This is useful for when you need to do
1065 something but it can't be done during the current event handler.  The
1066 implementation is very simple, see wxPython/wx.py.</p>
1067 <p>Fixed a boatload of reference leaks.</p>
1068 <p>Added a demo of using a sizer in a wxScrolledWindow, in effect
1069 creating a ScrolledPanel.</p>
1070 <p>Added a sample to the demo that shows how to use radio menu items, and
1071 other menu stuff.</p>
1072 <p>Added wxIEHtmlWin.  This is essentially the same as using IE with the
1073 ActiveXWrapper already in the library, but it is implemented all in
1074 C++ and therefore does not need any of the modules from win32all and
1075 so it is less fragile in the face of changes.</p>
1076 <p>Fixed the ActiveXWrapper problem.  Looks like when the win32com
1077 modules make a &quot;callback&quot; that they (incorrectly, IMHO) allocate a
1078 transient thread state structure.  Since wxPython is now saving
1079 tstates for it's own callbacks it ended up using garbage after
1080 win32com got rid of the temporary tstate...</p>
1081 <p>Added a generic static text control to wxPython.lib.stattext.  This is
1082 so things like Boa and PythonCard can have a static text that can
1083 respond to mouse events and etc.</p>
1084 <p>Changed the wxDateTime.Parse* methods to return an int that will be -1
1085 on failure, and the index where parsing stopped otherwise.</p>
1086 <p>Moved tools to be a Python package in wxPython.tools, added scripts to
1087 import and launch each tool.  This will let you import and use the
1088 tools in your own scripts or apps as needed.  On Linux and OS X the
1089 tool scripts are installed to {prefix}/bin so you should be able to
1090 easily launch them from the command line.  For example, PyCrust can be
1091 started with just the &quot;pycrust&quot; command.</p>
1092 <p>Added a sample to the demo that catches various key events and
1093 displays the details of the event.</p>
1094 <p>Added wxWizard, wxWizardPage, wxWizardPageSimple and wxPyWizardPage.</p>
1095 <p>Added wxXmlResourceHandler which allows you to create custom handlers
1096 for nonstandard class types in XRC resources.  See the demo for an
1097 example.</p>
1098 <p>Added wxPython.lib.mixins.rubberband module from Robb Shecter.</p>
1099 <p>Added wxTimeCtrl from Will Sadkin.</p>
1100 </div>
1101 <div class="section" id="id18">
1102 <h1><a name="id18">2.3.2.1</a></h1>
1103 <p>Changed (again) how the Python global interpreter lock is handled as
1104 well as the Python thread state.  This time it works on SMP machines
1105 without barfing and is also still compatible with Python debuggers.</p>
1106 <p>Added some patches from library contributors.</p>
1107 </div>
1108 <div class="section" id="id19">
1109 <h1><a name="id19">2.3.2</a></h1>
1110 <p>Added EVT_HELP, EVT_HELP_RANGE, EVT_DETAILED_HELP,
1111 EVT_DETAILED_HELP_RANGE, EVT_CONTEXT_MENU, wxHelpEvent,
1112 wxContextMenuEvent, wxContextHelp, wxContextHelpButton, wxTipWindow,
1113 and a demo to show them in action.</p>
1114 <p>Deprecated PyShell and PyShellWindow, added a snapshot of PyCrust (see
1115 <a class="reference" href="http://sourceforge.net/projects/pycrust/">http://sourceforge.net/projects/pycrust/</a>. )</p>
1116 <p>Added the new virtual list capabilities to wxListCtrl.</p>
1117 <p>Added a wxSTC style editor from Riaan Booysen to the sample apps.</p>
1118 <p>Added XRCed to the wxPython Tools directory, contributed by Roman
1119 Rolinsky.</p>
1120 <p>Added a new &quot;constructor&quot; to most of the window classes that calls the
1121 default C++ constructor, (the one with no parameters) and also added the
1122 corresponding  Create(...) method.  This allows you to do a 2-step
1123 creation of windows which is sometimes required for doing things such
1124 as setting extended style flags before the window is created, or for
1125 passing the object to the XRC resource system to be created from the
1126 resource.  The name of the new &quot;constructor&quot; is the original name of
1127 the class with a &quot;Pre&quot; in it.  For example, wxPreWindow, wxPreFrame,
1128 etc.</p>
1129 <p>Updated to version 1.40 of Scintilla and updated wxStyledTextCtrl
1130 accordingly.  While doing this update I dropped the wxLB_SORT style
1131 from the wxListBox created for the AutoComplete functionality.  This
1132 means that you will have to sort the keyword lists yourself, but you
1133 are free to do case sensitive or case insensitive sorts and set the
1134 wxSTC flag accordingly.</p>
1135 <p>Updated wxColumnSorterMixin to also be able to place sort icons on the
1136 column headers, and updated the wxListCtrl demo to show it off by
1137 using wxColumnSorterMixin.</p>
1138 <p>Added wxGenBitmapTextButton, TablePrint, etc. contribs from Lorne White.</p>
1139 <p>Added wxNativeFontInfo and wxFontMapper.</p>
1140 <p>Added pySketch to the samples.</p>
1141 <p>Significantly changed how the Python interpreter lock and thread state
1142 are managed, which should fix the problem of running on a
1143 multi-processor machine.</p>
1144 <p>Added wxPyLog so log targets can be created in Python to handle log
1145 messages however is wished.  See demo/Main.py for an example.</p>
1146 <p>Added wxFindReplaceDialog.</p>
1147 <p>The second phase of OOR is implemented for wxEvtHandler, wxSizer,
1148 wxShape and derived classes.  This means that functions and methods
1149 that return an object derived from wxEvtHandler that was originally
1150 created in Python, will return the original Python object (if it still
1151 exists) instead of letting SWIG wrap a new shadow object around the
1152 original C++ pointer.</p>
1153 <p>Added some optimization methods to wxDC: GetBoundingBox, DrawLineList,
1154 DrawPointList.</p>
1155 <p>Added a set of sophisticated Error Dialogs from Chris Fama.</p>
1156 <p>Added wxRightTextCtrl from Josu Oyanguren to wxPython.lib for aligning
1157 text in a wxTextCtrl to the right side.</p>
1158 <p>Added wxURLDataObject and an example showing drag and drop of URLs to
1159 and from web browsers.  It's still not 100% bullet-proof for all types
1160 of browsers, but it works for the majority of cases with the popular
1161 browsers on Windows.  On wxGTK it seems that only Netscape 4.x works,
1162 if anybody has any suggestions about this please bring it up on the
1163 wx-dev list.</p>
1164 <p>Added wxStopWatch.</p>
1165 <p>Added wxMimeTypesManager and wxFileType.</p>
1166 <p>Passing None for the handler parameter to one of the EVT_** functions
1167 will now Disconnect the event.</p>
1168 <p>Added wxPopupWindow and wxPopupTransientWindow.</p>
1169 <p>Added wxFileHistory.</p>
1170 <p>Added wxDynamicSashWindow, which allows you to endlessly split windows
1171 by dragging a little tab next to the scrollbars.  Added a demo to show
1172 this and also the ability of multiple wxStyledTextCtrls to share the
1173 same document.</p>
1174 <p>Added wxEditableListBox gizmo.</p>
1175 <p>Updated wxEditor with lots of enhancements from Steve Howell and Adam
1176 Feuer.</p>
1177 <p>Added the &quot;SplitTree gizmos&quot; which are a collection of classes that
1178 were designed to operate together and provide a tree control with
1179 additional columns for each item.  The classes are
1180 wxRemotelyScrolledTreeCtrl, wxTreeCompanionWindow,
1181 wxThinSplitterWindow, and wxSplitterScrolledWindow, some of which may
1182 also be useful by themselves.</p>
1183 <p>Added wxDllWidget from Vaclav Slavik which allows wx widgets derived
1184 from wxWindow to be loaded from a C++ .dll (or .so) and be used in a
1185 wxPython program, without the widget having to be SWIGged first.  The
1186 visible API of the widget is limited to wxWindow methods plus a
1187 SendCommand method, but it is still quite powerful.  See
1188 wxPython/contrib/dllwidget and wxPython/demo/dllwidget for more
1189 details.</p>
1190 </div>
1191 <div class="section" id="id20">
1192 <h1><a name="id20">2.3.1</a></h1>
1193 <p>Added EVT_GRID_EDITOR_CREATED and wxGridEditorCreatedEvent so the user
1194 code can get access to the edit control when it is created, (to push
1195 on a custom event handler for example.)</p>
1196 <p>Added wxTextAttr class and SetStyle, SetDefaultStyle and
1197 GetDefaultStyle methods to wxTextCtrl.</p>
1198 <p>Added ability to use xml resource files.  Still need to add ability to
1199 subclass wxXmlResourceHandler, etc...</p>
1200 <p>Added wxGridAutoEditMixin to the mixins library package.</p>
1201 <p>Made ColourSelect be derived from wxButton.</p>
1202 <p>Fixed img2py to work correctly with Python 2.1.</p>
1203 <p>Added enhanced wxVTKRenderWindow by Prabhu Ramachandran</p>
1204 </div>
1205 <div class="section" id="id21">
1206 <h1><a name="id21">2.3.0</a></h1>
1207 <p>Removed initial startup dependency on the OpenGL DLLs so only the
1208 glcanvasc.pyd depends on them, (on wxMSW.)</p>
1209 <p>Changed wxFont, wxPen, wxBrush to not implicitly use the
1210 wxThe[Font|Pen|Brush]List objects behind the scenes, but to use normal
1211 ctor and dtors.</p>
1212 <p>Exposed the wxThe[Font|Pen|Brush]List to wxPython.</p>
1213 <p>Also added wxTheColourDatabase and added a library module (in the
1214 wxPython.lib.colourdb module) to load LOTS more colour names into the
1215 colour database.</p>
1216 <p>Added wxWakeUpMainThread, wxMutexGuiEnter, wxMutexGuiLeave,
1217 wxMutexGuiLocker and wxThread_IsMain to assist with dealing with GUI
1218 access from non-GUI threads.</p>
1219 <p>wxPyOnDemandOutputWindow is now (more) thread safe if non-GUI threads
1220 use print, sys.stdout.write, etc.</p>
1221 <p>Added CreateTextSizer and CreateButtonSizer to wxDialog</p>
1222 <p>Added wxPython/lib/infoframe.py from Chris Fama.  It contains a class
1223 that can be used in place of wxPyOnDemandOutputWindow.</p>
1224 <p>Added colourselect.py, imagebrowser.py and an updated calendar.py to
1225 wxPython/lib from Lorne White.</p>
1226 <p>Added patch to wxPoint_LIST_helper from Tim Hochberg that should make
1227 it gobs faster in certain situations.</p>
1228 <p>Added tools that will take an image file in a wx supported format and
1229 convert it to data embedded in a Python source file.  The image is
1230 converted to XPM format which is essentially a list of strings
1231 containing info about each pixel.  The image's transparency mask is
1232 included, if there is one, or a mask can be added if a mask colour is
1233 specified on the command line.  It is then pickled and optionally
1234 compressed and written to a Python source file along with functions to
1235 convert it to either a wxBitmap or a wxImage.  See
1236 wxPython/demo/images.py for examples, and wxPython/Tools/img2py.py for
1237 the implementation.</p>
1238 <p>Fixed wxStyledTextCtrl to be much faster on wxGTK.  There was some
1239 experimental code that got left in place that ended up causing way too
1240 many refreshes.</p>
1241 <p>A couple more hacks in my_distutils.py so wxPython can be built with
1242 the distutils that comes with Python 2.1.</p>
1243 <p>Added a ton of missing methods for wxPrintData.</p>
1244 <p>Switched to InnoSetup for MSW distributions.</p>
1245 <p>Added wxToggleButton.</p>
1246 <p>Fixed bug that prevented wxTreeCtrl.OnCompareItems from being called.</p>
1247 <dl>
1248 <dt>Added some methods to wxGrid:</dt>
1249 <dd>GetCellHighlightPenWidth
1250 GetCellHighlightROPenWidth
1251 SetCellHighlightPenWidth
1252 SetCellHighlightROPenWidth
1253 GetGridWindow
1254 GetGridRowLabelWindow
1255 GetGridColLabelWindow
1256 GetGridCornerLabelWindow</dd>
1257 </dl>
1258 <p>Added wxGetClientDisplayRect which on wxMSW returns a wxRect
1259 representing the area on screen not occupied by the taskbar and such.
1260 On other platforms it is equivallent to wxGetDisplaySize.</p>
1261 <dl>
1262 <dt>OOR:</dt>
1263 <dd><p class="first">Implemented the first phase of OOR (Original Object Return).  See
1264 the text in the demo for more details of what this means, but in a
1265 nutshell methods such as wxWindow.GetParent or FindWindowById will
1266 now return a shadow object of the proper type if it can.  By
1267 &quot;proper type&quot; I mean that if the wxWindow pointer returned from
1268 FindWindowById really points to a wxButton then the Python object
1269 constructed will be of a wxButtonPtr class instead of wxWindowPtr
1270 as before.  This should reduce or eliminiate the need for
1271 wxPyTypeCast.  (Woo Hoo!)  The objects returned are still not the
1272 original Python object, but that is the next step.  (Although it
1273 will probably only work on Python 2.1 and beyond because it will
1274 use weak references.)</p>
1275 <p class="last">This first phase of the OOR plan is fairly significant and has
1276 required a lot of changes all over wxPython, most of which should
1277 be transparent to you, however I'm not 100% sure that it didn't
1278 introduce any new bugs that are hiding somewhere and didn't get
1279 stomped on during my testing.  So please be sure to test everything
1280 thoroughly when you install this version and be sure to report any
1281 object-type related oddities to me.</p>
1282 </dd>
1283 </dl>
1284 <p>There is now a wxObject class that most other classes derive from like
1285 in C++, but the methods provided don't really match but are wxPython
1286 specific.  It could have been added long ago but OOR required it so it
1287 finally got done.</p>
1288 <p>Finally added wxPyLineShape.GetLineControlPoints, which has been on my
1289 list for a while.  The above OOR modification made this easier.</p>
1290 <p>Fixed the __cmp__ methods for wxPoint and others.</p>
1291 <p>Added wxWave.</p>
1292 <p>Added the wxPython.lib.mixins package to the library, it is where
1293 useful mix-in classes can be placed.  Currently there is one to help
1294 make the columns in a wxListCtrl sortable, and the MagicIMageList from
1295 Mike Fletcher.  If you have any custom code that can be factored out
1296 of existing classes into a mix-in that would be useful to others
1297 please send it to me for inclusion in this package.</p>
1298 <p>Added a few little sample applications to help newbies to get started
1299 by having smaller functional apps to play with.  They can be found in
1300 wxPython/samples.</p>
1301 </div>
1302 <div class="section" id="id22">
1303 <h1><a name="id22">2.2.6</a></h1>
1304 <p>No changes happened in the Python wrappers for this release, only
1305 changes and fixes in the wxWindows library.</p>
1306 </div>
1307 <div class="section" id="id23">
1308 <h1><a name="id23">2.2.5</a></h1>
1309 <p>New typemaps for wxString when compiling for Python 2.0 and beyond
1310 that allow Unicode objects to be passed as well as String objects.  If
1311 a Unicode object is passed PyString_AsStringAndSize is used to convert
1312 it to a wxString using the default encoding.</p>
1313 <p>Fixed the generic buttons so tool tips work for them.</p>
1314 <p>Fixed a bug in the demo's tree control.</p>
1315 <p>Added a listbox to the listbox demo that shows how to find items with
1316 a matching prefix as keys are typed.</p>
1317 <p>Added code to the wxListCtrl demo to show how to get text from a
1318 column in report mode.</p>
1319 <p>Added code to the toolbar demo to clear the long help from the status
1320 bar after 2 seconds.</p>
1321 <p>Added wxJoystick.</p>
1322 <p>Fixed wxTimer so it can be used as described in the docs, either with
1323 a Notify method in a subclass, or sending an event to a wxEvtHandler
1324 object, (usually a window.)</p>
1325 <p>Added wxNotifyEvent.Allow()</p>
1326 <p>Fixed GOBS of reference leaks.</p>
1327 <p>Massive code changes and cleanup to allow wxPython to be split into
1328 multiple extension modules again.  A Python CObject is used to allow
1329 the &quot;export&quot; of SWIG functions and other common helper functions from
1330 the wxc module to other modules, even if they are in separate shared
1331 libraries.  Should also be usable from 3rd party code, just include
1332 wxPython/src/export.h</p>
1333 <p>Changed the default setup so the following are built as separate
1334 extension modules:  calendar, glcanvas, grid, html, ogl, stc, and
1335 utils.  Will probably add more later.</p>
1336 <p>Changed the wxPrinterDC to use the new constructor taking a
1337 wxPrintData object.  The old ctor is still there using the
1338 wxPrinterDC2 name.</p>
1339 <p>Added wxPython.lib.anchors.py from Riaan Booysen.  It contains a class
1340 that implements Delphi's Anchors with wxLayoutConstraints.</p>
1341 <p>Added wxPython.lib.fancytext from Timothy Hochberg.</p>
1342 <p>Changed the GenericButtons to send their event in idle time, so the
1343 mouse won't be captured when the event handler is called.</p>
1344 <p>Added wxPython.lib.rpcMixin from Greg Landrum, although it's not
1345 integrated with the demo yet.  It allows a wxPython GUI to be an
1346 XML-RPC server.</p>
1347 </div>
1348 <div class="section" id="new-in-2-2-2">
1349 <h1><a name="new-in-2-2-2">New in 2.2.2</a></h1>
1350 <p>Significantly changed how the wxStyledtextCtrl code that wraps
1351 Scintilla is implemented.  Most of it is now automatically generated
1352 from an interface definition file provided by Scintilla.  This means
1353 that it will be much easier to stay in sync with new Scintilla
1354 releases, but also means that some of the method and identifier names
1355 have changed.  See wxPython/demo/data/stc.h for a copy of the C++
1356 interface from which the Python interface is generated.  There is now
1357 some inline documentation in that file that should really help explain
1358 how things work.</p>
1359 <p>I am now using the Python Distutils to build wxPython and to make some
1360 of the distribution files.  (See <a class="reference" href="http://www.python.org/sigs/distutils-sig/">http://www.python.org/sigs/distutils-sig/</a>)
1361 This means no more messing with my kludgy build.py/Makefile hack,
1362 builds will be more consistent with other Python extensions that also
1363 use Distutils, and will hopefully make wxPython easier to build for
1364 platforms where there have been troubles before.  If you are building
1365 wxPython for Python 1.5.2 or for 1.6, then you will need to get and
1366 install version 1.0 of Distutils from the website above.  If you are
1367 using Python 2.0 then you already have it.</p>
1368 <p>Added wxInputStream and the wxFileSystem family of classes,
1369 contributed by Joerg Baumann.</p>
1370 <p>Added wxProcess and support for it to wxExecute.  wxProcess lets you
1371 get notified when an asyncronous child process terminates, and also to
1372 get input/output streams for the child process's stdout, stderr and
1373 stdin.</p>
1374 <p>Removed the old python sizers.</p>
1375 <p>Added __add__, __sub__ and __cmp__ (equality check only) for wxPoint
1376 and wxRealPoint.</p>
1377 <p>Changed the build to make one big extension module instead of one for
1378 the core and each contrib.  This allowed me to do away with the
1379 libwxPyHelpers.so on unix systems.</p>
1380 <p>Lots of little fixes here and there.</p>
1381 <p>Some hacks on wxGTK to try and make the AutoComplete listbox in the
1382 wxStyledTextCtrl to behave better.  It's still not as nice as on
1383 wxMSW, but at least it's a bit more usable now.</p>

1400 depressed state.</p>
1401 <p>Added wxTipProvider and friends.  See the demo for an example.</p>

1407 <p>WARNING: A while back I asked what should be done about the Magic
1408 Method Names.  (Methods that are automatically turned into event
1409 handlers by virtue of their name.)  The consensus was that it is more
1410 confusing to have them than to try and expand them to have greater
1411 coverage.  I am finally getting around to removing the code that
1412 generates the event binding.  This means that if you are using any of
1413 the following method names without a EVT_* call that you need to
1414 modify your code to add the EVT_* to hook the event to the method.</p>
1415 <blockquote>
1416 OnChar
1417 OnSize
1418 OnEraseBackground
1419 OnSysColourChanged
1420 OnInitDialog
1421 OnPaint
1422 OnIdle
1423 OnActivate
1424 OnMenuHighlight
1425 OnCloseWindow

1430 <h1><a name="new-in-2-1-15">New in 2.1.15</a></h1>
1431 <p>Fixed wxTreeCtrl.HitTest to return both the tree item as well as the
1432 flags that clairify where the click was in relation to the item.</p>
1433 <p>Fixed thread state problem in wxTreeCtrl.GetBoundingBox and
1434 GetSelections.</p>
1435 <p>Fixed some problems in OGL.  Also wxShape.SetClientData and
1436 .GetClientData can now deal with Python objects.</p>
1437 <p>Added wxListCtrl.SortItems and changed the demo to show how to use it.</p>
1438 <p>Plugged a memory leak.</p>
1439 <p>Wrapped the new wxGrid and friends.  The old wxGrid class is no longer
1440 available.  There are some incompatibilities, and unfortunately the
1441 new classes are not documented yet, (however the methods are more
1442 consistent with each other now so you may be able to guess pretty
1443 good...)</p>
1444 <p>Updated filebrowsebutton.py and calendar.py with changes from their
1445 authors.  There is now a FileBrowseButtonWithHistory class (what a
1446 mouthful!) and wxCalendar has printing support.</p>
1447 <p>Added ActiveXWrapper to the library, and some good demos of it too.
1448 It works great for embedding a COM (a.k.a OCX, a.k.a ActiveX) control
1449 in a window and calling its methods.  It actually creates a new class
1450 on the fly that derives from wxWindow, the COM CoClass and others
1451 needed to make it all work.  The resulting class can be instantiated
1452 just like wxWindow, used in sizers, etc.  It also responds to all COM
1453 method calls, properties, etc., and if the class or a mix-in has
1454 matching method names, then the COM events will be propogated back to
1455 them.</p>
1456 <p>Created a typemap that allows a string to be used for parameters
1457 expecting a wxColour type.  The string is either a colour name as
1458 defined in the wxColourDatabase, or a colour spec of the form
1459 &quot;#RRGGBB&quot;.  See the wxStyledTextCtrl demo for an example.</p>
1460 <p>I almost forgot to mention the wxStyledTextCtrl!  Yes, the
1461 wxStyledTextCtrl is finally in wxPython!!  (And the crowd goes
1462 wild...)   There's no documentaTion yet (the crowd boos and hisses...)
1463 but I've included a very readable source file in the
1464 wxPython/demo/data directory, a couple fairly good examples, and you
1465 can also refer to the Scintilla documentaion at
1466 <a class="reference" href="http://www.scintilla.org/ScintillaDoc.html">http://www.scintilla.org/ScintillaDoc.html</a> to help fill in the gaps
1467 until the docs are done.  (The croud murmers contentedly as the tool
1468 provider smiles convincingly and removes his flame-proof suit.)</p>

1471 <h1><a name="what-s-new-in-2-1-13">What's new in 2.1.13</a></h1>
1472 <p>Skipped a version number to match what has been released for wxGTK.</p>
1473 <p>Updated wxMVCTree and added a demo for it, also fixed layout on GTK
1474 and some flicker problems.</p>
1475 <p>Added a wrapper class for the Visualization ToolKit (or VTK) in the
1476 wxPython.lib.vtk module.  (<a class="reference" href="http://www.kitware.com/">http://www.kitware.com/</a>)</p>
1477 <p>Fixed wxTreeCtrl.SetItemImage and GetItemImage to recognise the new
1478 &quot;which&quot; parameter.</p>
1479 <p>Added wxPython.lib.spashscreen from Mike Fletcher.</p>
1480 <p>Added wxPython.lib.filebrowsebutton also from Mike Fletcher.</p>
1481 <p>Renamed wxTreeCtrl.GetParent to GetItemParent to avoid a name clash
1482 with wxWindow.GetParent.</p>
1483 <p>Added wxIntersectRect to compute the intersection of two wxRect's.
1484 It is used like this:</p>
1485 <blockquote>
1486 intersect = wxIntersectRect(rect1, rect2)</blockquote>
1487 <p>If r1 and r2 don't intersect then None is returned, otherwise the
1488 rectangle representing the intersection is returned.</p>
1489 <p>Some bug fixes for Clipboard and Drag-n-Drop.</p>
1490 <p>Rotated text!!!  WooHoo!  (See wxDC.DrawRotatedText())</p>
1491 <p>Added a set of Generic Buttons to the library.  These are simple
1492 window classes that look and act like native buttons, but you can have
1493 a bit more control over them.  The bezel width can be set in addition
1494 to colours, fonts, etc.  There is a ToggleButton as well as Bitmap
1495 versions too.  They should also serve as a good example of how to
1496 create your own classes derived from wxControl.</p>
1497 <p>The C++ wxToolBar classes have been redone, and so have the wxPython
1498 wrappers.  There have been slight modifications to some of the methods
1499 but shouldn't impact anybody too much.  I took the opportunity to add
1500 support for setting user data on each toolbar tool.  The new AddTool
1501 methods look like this:</p>
1502 <blockquote>
1503 <dl>
1504 <dt>def AddTool(ID,</dt>
1505 <dd>bitmap,
1506 pushedBitmap = wxNullBitmap,
1507 toggle = FALSE,
1508 clientData = NULL,
1509 shortHelpString = &quot;&quot;,
1510 longHelpString = &quot;&quot;)</dd>
1511 <dt>def AddSimpleTool(ID,</dt>
1512 <dd>bitmap,
1513 shortHelpString = &quot;&quot;,
1514 longHelpString = &quot;&quot;,
1515 toggle=FALSE)</dd>
1516 </dl>
1517 </blockquote>
1518 <p>There are also corresponding InsertTool and InsertSimpleTool methods
1519 that additionally take an integer position as the first parameter.</p>
1520 <p>Added a wrapper for the new PCX and TIFF ImageHandlers.</p>
1521 <p>wxRect now simulates attributes named left, right, top and bottom.</p>
1522 <p>Removed all non wx stuff from the glcanvas module since DA's PyOpenGL
1523 is better and compatible with the wxGLCanvas.  You can get it at
1524 <a class="reference" href="http://starship.python.net:9673/crew/da/Code/PyOpenGL">http://starship.python.net:9673/crew/da/Code/PyOpenGL</a>.</p>
1525 <p>Added some missing EVT functions.</p>
1526 <p>Added Dirk Holtwic's editor classes to the wxPython.lib.editor
1527 package.</p>
1528 <p>Changed all the &quot;LIST&quot; parameter names to &quot;choices&quot; to match the docs.</p>
1529 <p>More fixes for the wxFloatBar, and it now works on wxGTK even better
1530 than wxMSW!  (The feat is accomplished by using the wxTB_DOCKABLE
1531 style flag instead of trying to float it ourselves.)</p>

1534 <h1><a name="what-s-new-in-2-1-11">What's new in 2.1.11</a></h1>
1535 <p>Skipped a few version numbers so wxMSW, wxGTK and wxPython are all
1536 syncronized.</p>
1537 <p>wxImage.SetData now makes a copy of the image data before giving it to
1538 wxImage.  I mistakenly thought that wxImage would copy the data
1539 itself.</p>
1540 <p>Fixed wxMSW's notebook so the pages get their size set as they are
1541 being added.  This should remove the need for our
1542 wxNotebook.ResizeChildren hack.</p>
1543 <p>wxPanels now support AutoLayout, and wxNotebooks and wxSplitterWindows
1544 no longer tell their children to Layout() themselves.  This will
1545 probably only effect you if you have a wxWindow with AutoLayout inside
1546 a notebook or splitter.  If so, either change it to a wxPanel or add
1547 an EVT_SIZE handler that calls Layout().</p>
1548 <p>Fixed deadlock problem that happened when using threads.</p>
1549 <p>Added new HTML printing classes.</p>
1550 <p>Added wxWindow.GetHandle</p>
1551 <p>Apparently wxMouseEvent.Position has been deprecated in wxWindows as
1552 it is no longer available by default.  You can use GetPositionTuple
1553 (returning a tuple with x,y) instead, or GetPosition (returning a
1554 wxPoint.)</p>
1555 <p>Added wxPostEvent function that allows events to be posted and then
1556 processed later.  This is a thread-safe way to interact with the GUI
1557 thread from other threads.</p>
1558 <p>Added Clipboard and Drag-and-Drop classes.</p>
1559 <p>Added wxFontEnumerator.</p>
1560 <p>Many updates to wxMenu, wxMenuBar.</p>
1561 <p>wxPyEvent and wxPyCommandEvent derived classes now give you the actual
1562 Python object in the event handler instead of a new shadow.</p>
1563 <p>Added a Calendar widget from Lorne White to the library.</p>
1564 <p>Made some fixes to the wxFloatbar.  It still has some troubles on
1565 wxGTK...</p>

1577 wxMSW.  For MSW this isn't much of a problem since you can get the
1578 binaries from the web site.  For other platforms you'll have to build
1579 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>)

1583 <p>Much more support for event-less callbacks and add-on modules.</p>
1584 <p>Created add-on module with wxOGL classes.</p>
1585 <p>Added wxWindow.GetChildren().  Be careful of this.  It returns a <em>copy</em>
1586 of the list of the window's children.  While you are using the list if
1587 anything changes in the real list (a child is deleted, etc.) then the
1588 list you are holding will suddenly have window references to garbage
1589 memory and your app will likely crash.  But if you are careful it works
1590 great!</p>
1591 <p>Added a bunch of new and missing methods to wxTreeCrtl.  The
1592 SortChildren method is now supported, but currently only for the
1593 default sort order.</p>
1594 <p>Added typemaps for wxSize, wxPoint, wxRealPoint, and wxRect that allow
1595 either the actual objects or Python sequence values to be used.  For
1596 example, the following are equivallent:</p>
1597 <blockquote>
1598 win = wxWindow(parent, size = wxSize(100, 100))
1599 win = wxWindow(parent, size = (100, 100))</blockquote>
1600 <p>Super-charged the wxHtml module.  You can now create your own tag
1601 handlers and also have access to the parser and cell classes.  There
1602 is a tag handler in the library at wxPython.lib.wxpTag that
1603 understands the WXP tag and is able to place wxPython windows on HTML
1604 pages.  See the demo for an example.</p>
1605 <p>A bunch of the methods of wxMenuBar were previously ifdef'd out for
1606 wxGTK.  Added them back in since the methods exist now.</p>
1607 <p>Wrapped the wxHtmlHelpController and related classes.</p>
1608 <p>Wrapped the C++ versions of wxSizer and friends.  The Python-only
1609 versions are still in the library, but deprecated.  (You will get a
1610 warning message if you try to use them, but the warning can be
1611 disabled.) The usage of the C++ versions is slightly different, and
1612 the functionality of wxBorderSizer is now part of wxBoxSizer.  I have
1613 added a few methods to wxSizer to try and make the transition as
1614 smooth as possible, I combined all Add methods into a single method
1615 that handles all cases, added an AddMany method, etc.  One step I did
1616 not take was to make the default value of flag in the Add method be
1617 wxGROW.  This would have made it more backward compatible, but less
1618 portable to and from wxWin C++ code.  Please see the docs and demo for
1619 further details.</p>
1620 <p>Added wxPyEvent and wxPyCommandEvent classes, derived from wxEvent and
1621 wxCommandEvent.  Each of them has SetPyData and GetPyData methods that
1622 accept or return a single Python object.  You can use these classes
1623 directly or derive from them to create your own types of event objects
1624 that can pass through the wxWindows event system without loosing their
1625 Python parts (as long as they are stored with SetPyData.)  Stay tuned
1626 for more info and examples in future releases.</p>
1627 <p>Added wxPython.lib.grids as an example of how to derive a new sizer
1628 from the C++ sizers.  In this module you will find wxGridSizer and
1629 wxFlexGridSizer.  wxGridSizer arrainges its items in a grid in which
1630 all the widths and heights are the same.  wxFlexgridSizer allows
1631 different widths and heights, and you can also specify rows and/or
1632 columns that are growable.  See the demo for a couple examples for how
1633 to use them.</p>
1634 <p>Added the wxValidator class, and created a class named wxPyValidator
1635 that should be used for the base class of any Python validators.  See
1636 the demo for an example.  Please note that you MUST implement a Clone
1637 method in your validator classes because of the way some things work
1638 in the underlying C++ library.  I did not add wxTextValidator because
1639 of some issues of how it transfers data to and from a wxString, which
1640 in wxPython is automatically translated to and from Python strings, so
1641 there would never be a concrete wxString that would hang around long
1642 enough for the validator to do its job.  On the other hand, it should
1643 be real easy to duplicate the functionality of wxTextValidator in a
1644 pure Python class derived from wxPyValidator.</p>
1645 <p>I've finally added a feature that has been on my list for close to two
1646 years!  Ever wondered what that zero is for when you create your app
1647 object?  Well now you can leave it out or explicitly set it to a true
1648 value.  This value now controls what is to be done with sys.stdout and
1649 sys.stderr.  A false value leaves them alone, and a true value sets
1650 them to an instance of wxPyOnDemandOutputWindow.  (On windows the
1651 default is true, on unix platforms the default is false.)  This class
1652 creates a frame containing a wxTextCtrl as soon as anything is written
1653 to sys.stdout or sys.stderr.  If you close the window it will come
1654 back again the next time something is written.  (You can call
1655 app.RestoreStdio to turn this off.)  If you would rather that the stdio be
1656 redirected to a file, you can provide a second parameter to your app
1657 object's constructor that is a filename.  If you want to use your own
1658 class instead of wxPyOnDemandOutputWindow you can either implement
1659 RedirectStdio() in you app class or change the value of
1660 wxApp.outputWindowClass like this:</p>
1661 <blockquote>
1662 <dl>
1663 <dt>class MyApp(wxApp):</dt>
1664 <dd><p class="first">outputWindowClass = MyClass</p>
1665 <dl class="last">
1666 <dt>def OnInit(self):</dt>
1667 <dd>frame = MyFrame()
1668 self.SetTopWindow(frame)
1669 return true</dd>
1670 </dl>
1671 </dd>
1672 </dl>
1673 </blockquote>
1674 <p>Please see the implementation of wxPyOnDemandOutputWindow and wxApp in
1675 wx.py for more details.  A few words of caution:  if you are running
1676 your app in a debugger, changing sys.stdout and sys.stderr is likely
1677 to really screw things up.</p>
1678 <p>Added wxCaret.  Unfortunately it's author has still not documented it
1679 in the wxWindows docs...</p>
1680 <p>Some new 3rd party contributions in wxPython.lib.  PyShell, in
1681 shell.py is an interesting implementaion of an interactive Python
1682 shell in wxWindows.  floatbar.py has a class derived from wxToolBar
1683 that can sense mouse drags and then reparent itself into another
1684 frame. Moving the new frame close to where it came from puts the tool
1685 bar back into the original parent.  (Unfortunately there is currently
1686 a bug in wxGTK's wxFrame.SetToolBar so the FloatBar has some
1687 problems...)</p>

1690 <h1><a name="what-s-new-in-2-1b3">What's new in 2.1b3</a></h1>
1691 <p>This release is syncronized with release 2.1 snapshot 9 of wxWindows.</p>
1692 <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>)
1693 for some of the new features and such.  Also they have encorporated my
1694 patches so there is really no reason to stick with the current (very
1695 old) release...  This version of SWIG gives the following new
1696 features:</p>
1697 <blockquote>
1698 <ol class="arabic">
1699 <li><p class="first">Keyword arguments.  You no longer have to specify all the
1700 parameters with defaults to a method just to specify a
1701 non-default value on the end.  You can now do this instead:</p>
1702 <blockquote>
1703 <p>win = wxWindow(parent, -1, style = mystyle)</p>
1704 </blockquote>
1705 </li>
1706 <li><p class="first">There is now an an equivalence between Python's None and C++'s
1707 NULL.  This means that any methods that might return NULL will
1708 now return None and you can use none where wxWindows might be
1709 expecting NULL.  This makes things much more snake-ish.</p>
1710 </li>
1711 </ol>
1712 </blockquote>
1713 <p>There is a new build system based on a new Python program instead of
1714 raw makefiles.  Now wxPython builds are virtually the same on MSW or
1715 Unix systems.  See the end of this file for new build instructions and
1716 see distrib/build.py for more details.</p>
1717 <p>wxDC.Bilt now includes the useMask parameter, and has been split into
1718 two different versions.  wxDC.BlitXY is like what was there before and
1719 takes raw coordinants and sizes, and the new wxDC.Blit is for the new
1720 interface using wxPoints and a wxSize.</p>

1723 <h1><a name="what-s-new-in-2-1b2">What's new in 2.1b2</a></h1>
1724 <p>Added the missing wxWindow.GetUpdateRegion() method.</p>
1725 <p>Made a new change in SWIG (update your patches everybody) that
1726 provides a fix for global shadow objects that get an exception in
1727 their __del__ when their extension module has already been deleted.
1728 It was only a 1 line change in .../SWIG/Modules/pycpp.cxx at about
1729 line 496 if you want to do it by hand.</p>
1730 <p>It is now possible to run through MainLoop more than once in any one
1731 process.  The cleanup that used to happen as MainLoop completed (and
1732 prevented it from running again) has been delayed until the wxc module
1733 is being unloaded by Python.</p>
1734 <p>I fixed a bunch of stuff in the C++ version of wxGrid so it wouldn't
1735 make wxPython look bad.</p>
1736 <p>wxWindow.PopupMenu() now takes a wxPoint instead of  x,y.  Added
1737 wxWindow.PopupMenuXY to be consistent with some other methods.</p>
1738 <p>Added wxGrid.SetEditInPlace and wxGrid.GetEditInPlace.</p>
1739 <p>You can now provide your own app.MainLoop method.  See
1740 wxPython/demo/demoMainLoop.py for an example and some explaination.</p>
1741 <p>Got the in-place-edit for the wxTreeCtrl fixed and added some demo
1742 code to show how to use it.</p>
1743 <p>Put the wxIcon constructor back in for GTK as it now has one that
1744 matches MSW's.</p>
1745 <p>Added wxGrid.GetCells</p>
1746 <p>Added wxSystemSettings static methods as functions with names like
1747 wxSystemSettings_GetSystemColour.</p>
1748 <p>Removed wxPyMenu since using menu callbacks have been deprecated in
1749 wxWindows.  Use wxMenu and events instead.</p>
1750 <dl>
1751 <dt>Added alternate wxBitmap constructor (for MSW only) as</dt>
1752 <dd>wxBitmapFromData(data, type, width, height, depth = 1)</dd>
1753 </dl>
1754 <p>Added a helper function named wxPyTypeCast that can convert shadow
1755 objects of one type into shadow objects of another type.  (Like doing
1756 a down-cast.)  See the implementation in wx.py for some docs.</p>
1757 <p>Fixed wxImage GetData and SetData to properly use String objects for
1758 data transfer.</p>
1759 <p>Added access methods to wxGridEvent.</p>
1760 <p>New Makefile/Setup files supporting multiple dynamic extension modules
1761 for unix systems.</p>
1762 <p>Fixes for the wxGLCanvas demo to work around a strange bug in gtk.</p>
1763 <p>SWIG support routines now compiled separately instead of being bundled
1764 in wx.cpp.</p>

1767 <h1><a name="what-s-new-in-2-1b1">What's new in 2.1b1</a></h1>
1768 <p>Fixed wxComboBox.SetSelection so that it actually sets the selected
1769 item.  (Actually just removed it from wxPython and let it default to
1770 wxChoice.SetSelection which was already doing the right thing.)</p>
1771 <p>Added the Printing Framework.</p>
1772 <p>Switched back to using the wxWindows DLL for the pre-built Win32
1773 version.  The problem was needing to reinitialize static class info
1774 data after loading each extension module.</p>
1775 <p>Lots of little tweaks and additions to reflect changes to various
1776 wxWindows classes.</p>
1777 <p>Fixed a bug with attaching objects to tree items.  Actually was a
1778 symptom of a larger problem with not obtaining the interpreter lock
1779 when doing any Py_DECREFs.</p>
1780 <p>wxSizer and friends.  Sizers are layout tools that manage a colection
1781 of windows and sizers.  Different types of sizers apply different
1782 types of layout algorithms.  You saw it here first!  These classes are
1783 not even in the wxWindows C++ library yet!</p>

1788 <p>Bug fix for occassional GPF on Win32 systems upon termination of a
1789 wxPython application.</p>
1790 <p>Added wxListBox.GetSelections returning selections as a Tuple.</p>
1791 <p>Added a wxTreeItemData that is able to hold any Python object and be
1792 associated with items in a wxTreeCtrl.  Added test pytree.py to show
1793 this feature off.</p>
1794 <p>Added wxSafeYield function.</p>
1795 <p>OpenGL Canvas can be optionally compiled in to wxPython.</p>
1796 <p>Awesome new Demo Framework for showing off wxPython and for learning
1797 how it all works.</p>
1798 <p>The pre-built Win32 version is no longer distributing the wxWindows
1799 DLL.  It is statically linked with the wxWindows library instead.</p>
1800 <p>Added a couple missing items from the docs.</p>
1801 <p>Added wxImage, wxImageHandler, wxPNGHandler, wxJPEGHandler,
1802 wxGIFHandler and wxBMPHandler.</p>
1803 <p>Added new methods to wxTextCtrl.</p>

1825 <p>Well obviously the numbering scheme has changed.  I did this to
1826 reflect the fact that this truly is the second major revision of
1827 wxPython, (well the third actually if you count the one I did for
1828 wxWindows 1.68 and then threw away...) and also that it is associated
1829 with the 2.0 version of wxWindows.</p>
1830 <p>I have finally started documenting wxPython.  There are several pages
1831 in the wxWindows documentation tree specifically about wxPython, and I
1832 have added notes within the class references about where and how wxPython
1833 diverges from wxWindows.</p>
1834 <p>Added wxWindow_FromHWND(hWnd) for wxMSW to construct a wxWindow from a
1835 window handle.  If you can get the window handle into the python code,
1836 it should just work...  More news on this later.</p>
1837 <p>Added wxImageList, wxToolTip.</p>
1838 <p>Re-enabled wxConfig.DeleteAll() since it is reportedly fixed for the
1839 wxRegConfig class.</p>

1864 <p>wxPython on wxGTK works!!!  Both dynamic and static on Linux and
1865 static on Solaris have been tested.  Many thanks go to Harm
1866 &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
1867 down a nasty DECREF bug.  Okay so I have to confess that it was just a
1868 DSM (Dumb Stupid Mistake) on my part but it was nasty none the less
1869 because the behavior was so different on different platforms.</p>
1870 <p>The dynamicly loaded module on Solaris is still segfaulting, so it
1871 must have been a different issue all along...</p>

1875 <p>1. Worked on wxGTK compatibility.  It is partially working.  On a
1876 Solaris/Sparc box wxPython is working but only when it is statically
1877 linked with the Python interpreter.  When built as a dyamically loaded
1878 extension module, things start acting weirdly and it soon seg-faults.
1879 And on Linux both the statically linked and the dynamically linked
1880 version segfault shortly after starting up.</p>
