  13 <div class="section" id="id1">
  14 <h1><a name="id1">2.5.3.1</a></h1>
  15 <p>wxMac focus and border refreshes corrected.</p>
  16 <p>Updated internal PNG library.</p>
  17 <p>wxMac fix for metal appearance on wx.ToolBar.</p>
  18 <p>wx.grid.Grid fix allowing DoGetBestSize to be called before CreateGrid
  19 (which means that a min size doesn't need to be specified.)</p>
  20 <p>wxMac fix for not sending a native click to a control if it is not
  21 enabled (does an enable itself)</p>
  22 <p>Added wx.lib.ogl.DrawnShape, and fixed various little bugs in the new
  23 OGL.</p>
  24 <p>Added support to XRC and XRCed for the 3-state checkbox flags and also
  25 for wx.ToggleButton.  Updated the generic window styles supported by
  26 XRCed.</p>
  27 <p>It is now possible to create &quot;stock&quot; buttons.  Basically this means
  28 that you only have to provide one of the stock IDs (and either an
  29 empty label or a label that matches the stock label) when creating the
  30 button and wxWidgets will choose the stock label to go with it
  31 automatically.  Additionally on the platforms that have a native
  32 concept of a stock button (currently only GTK2) then the native stock
  33 button will be used.  For example, the following will result in a
  34 button with &quot;Cancel&quot; as the label and an accelerator on the &quot;C&quot;, and
  35 if run on wxGTK2 then there will also be an image of a red X:</p>
  36 <pre class="literal-block">
  37 b = wx.Button(parent, wx.ID_CANCEL)
  38 </pre>
  39 <p>Added wx.lib.ticker.Ticker class from Chris Mellon.</p>
  40 <p>Fix some incorrect clipping regions in wxSTC on wxGTK.</p>
  41 <p>Added wrapper for wx.grid.Grid.GetOrCreateCellAttr.</p>
  42 <p>Removed my copy of distutils from the wxPython source tree.  Now that
  43 I am no longer doing builds on Python 2.1 the newest distutils is no
  44 longer needed.  (There is still one small bug in Python 2.2 distutils
  45 on win32, but it is easily worked around.) This sovles the problem of
  46 incorrect builds on some systems where the system installed distutils
  47 has been patched to behave slightly differently, for example SuSE on
  48 x86_64 or Chandler's build.</p>
  49 <p>Updated to SWIG 1.3.22 (plus my patch.)  See wxPython/SWIG/README.txt
  50 in the source tree if you need to use SWIG when building your own copy
  51 of wxPython, or other extension modules that need to integrate with
  52 the wxPython modules.</p>
  53 <p>Added wx.Frame.RequestUserAttention which, if the platform suports it,
  54 will do something (such as flash the task bar item) to suggest to the
  55 user that they should look at that window.</p>
  56 <p>&quot;Fixed&quot; wx.grid.Grid.SetDefaultEditor and SetDefaultRenderer by making
  57 them register the editor or renderer for the &quot;string&quot; data type.</p>
  58 <p>Added depth param to wx.Image.ConvertToBitmap.</p>
  59 <p>Extended the wx.calendar.CalendarCtrl class with methods that get/set
  60 a Python datetime or date object.  (These will only work with Python
  61 2.3+) The methods are PySetDate, PyGetDate, PySetLowerDateLimit,
  62 PySetUpperDateLimit, PySetDateRange, PyGetLowerDateLimit, and
  63 PyGetUpperDateLimit.  Also, CalendarEvent was extended with PySetDate
  64 and PyGetDate methods.</p>
  65 <p>wxMSW: SetBackgroundColour on a wx.Choice or a wx.ComboBox will now
  66 also set the colour of the dropdown.</p>
  67 <p>wxMac: MessageDialog now supports wx.NO_DEFAULT style</p>
  68 <p>wxMSW: added AssociateHandle and DissociateHandle to wx.Window</p>
  69 <p>wxMac: fix for toolbar tooltips</p>
  70 <p>wx.Sizer.Show (and Hide) now take an optional parameter specifying if
  71 the item to be shown should be searched for recursivly in subsizers,
  72 and return a boolean value indicating if the item was found.</p>
  73 <p>wxMSW: fixed MaximizeEvent generation in wx.Frame</p>
  74 <p>wxMSW: fixed sending duplicate EVT_COMBOBOX events</p>
  75 <p>Smoother time estimation updates in wx.ProgressDialog (patch 992813)</p>
  76 <p>Made wx.Listbook events more consistent with wx.Notebook ones (patch
  77 1001271)</p>
  78 <p>Fixed rounding errors in variable status bar panes widths computation
  79 (patch 1030021)</p>
  80 <p>Added possibility to specify printer bin (patch 910272)</p>
  81 <p>wxMSW: fixed wx.ListCtrl's SetWindowStyleFlag() to not remove
  82 WS_VISIBLE; also refresh the control automatically (closes bug
  83 1019440)</p>
  84 <p>Added wx.Choicebook, yet another notebook-like control.</p>
  85 <p>wxMSW: Make radiobutton tab behaviour the same on MSW as in standard
  86 MSW app, i.e. tab into the activated, not necessarily the first radio
  87 button.</p>
  88 <p>Added limited support for wxEventLoop (you can't derive from a
  89 wx.PyEventLoop version yet...)  Updated and moved the sample showing
  90 how to replace the MainLoop to samples/mainloop/mainloop.py.</p>
  91 <p>The C++ xrc lib has been moved out of contrib and into the core, so it
  92 is always built by default.  wxPython's build has also changed
  93 accordingly and will build the xrc module as part of the core set of
  94 modules built by default.  If you were axplicitly using BUILD_XRC then
  95 it will no longer be recognized as a build option, otherwise you
  96 should notice no difference.</p>
  97 <p>wxMac: Fixed radio toolbar buttons to correctly untoggle the others
  98 when a new one is selected.</p>
  99 <p>wxMac: Fixed GetLineLength and GetLineText for MLTE text controls</p>
 100 <p>wxMac: wx.TaskBarIcon is implemented by allowing you to change the
 101 app's icon on the Dock and also specifying a menu that should be
 102 merged with the normal dock popup menu.  See the MigrationGuide for
 103 more details and a warning.</p>
 104 <p>Added wx.TopLevelWindow.IsActive() which tells you if the frame or
 105 dialog is or containts the active window with the keyboard focus.</p>
 106 <p>Added ability to create a font based on pixel size rather than point
 107 size via the FontFromPixelSize constructor.</p>
 108 <p>Updated the Scintilla used by StyledTextCtrl to version 1.61</p>
 109 <p>Improved image HitTest for TreeListCtrl.</p>
 110 <p>Added wx.App.IsMainLoopRunning.</p>
 111 <p>wxGTK: Make wxComboBox spit out a bit fewer surplus events when
 112 holding down the mouse button.</p>
 113 <p>wxGTK: Enable key based navigation through notebook tabs as in the
 114 native control with Left and right keys. Support for vetoing.</p>

 165 version installs, and comes with an uninstaller script.</p>
 166 </div>
 167 <div class="section" id="id2">

 194 </blockquote>
 195 </div>
 196 <div class="section" id="id3">
 197 <h1><a name="id3">2.5.2.7</a></h1>
 198 <p>wx.ADJUST_MINSIZE is now the default behaviour for window items in
 199 sizers.  This means that the item's GetMinSize and/or GetBestSize will
 200 be called when calculating layout and the return value from that will
 201 be used for the minimum size used by the sizer.  The wx.FIXED_MINSIZE
 202 flag was added that will cause the sizer to use the old behaviour in
 203 that it will <em>not</em> call the window's methods to determine the new best
 204 size, instead the minsize that the window had when added to the sizer
 205 (or the size the window was created with) will always be used.  Please
 206 see the Sizers section in the Migration Guide for more details.</p>
 207 <p>Added new MaskedEditControl code from Will Sadkin.  The modules are
 208 now locaed in their own sub-package, wx.lib.masked.  Demos updated.</p>
 209 <p>The changes that implemented the incompatible wx.DC methods in 2.5.1.5
 210 have been reverted.  The wx.DC methods are now compatible with the 2.4
 211 implemetation.  In addition a set of renamed methods have been added
 212 that take wx.Point and/or wx.Size objects instead of individual
 213 parameters.</p>
 214 <p>Added wx.lib.mixins.listctrl.TextEditMixin, a mixin class that allows
 215 all columns of a wx.ListCtrl in report mode to be edited.</p>
 216 <p>Deprecated the wx.iewin module.</p>
 217 <p>Deprecated the wx.Sizer.AddWindow, AddSizer, AddSpacer methods as well
 218 as their Insert* and Prepend* counterparts.</p>
 219 <p>Added a generic StaticBitmap class in wx.lib.statbmp for the same
 220 reasons that stattext was created, so it could be mouse sensitive on
 221 all platforms like normal windows.  Also updated stattext.py and
 222 buttons.py to handle attribute (font &amp; colour) defaults and
 223 inheritance the new way.  If you have custom controls of your own you
 224 should review stattxt.py or one of the others to see how it is to be
 225 done.</p>
 226 <p>wx.InitAllImageHandlers is now an empty function that does nothing but
 227 exist for backwards compatibility.  The C++ version is now called
 228 automatically when wxPython is initialized.  Since all the handlers
 229 are included in the wxWidgets shared library anyway, this imposes only
 230 a very small amount of overhead and removes several unneccessary
 231 problems.</p>
 232 <p>Replaced wx/lib/pubsub.py with a version that uses weak references to
 233 track the subscribers, plus other fixes/additions.  Thanks go to
 234 Oliver Schoenborn and Robb Shecter.</p>
 235 <p>wxGTK now uses gtk_init_check so wxPython can raise an exception if
 236 there is no DISPLAY available or other initializaion problem.</p>
 237 <p>wx.GetKeyState now has an implementation for wxGTK and is able to
 238 detect the up/down or toggle state of modifier and toggle keys.</p>
 239 <p>The LC_NUMERIC locale is now reset back to &quot;C&quot; (compatibility) when
 240 running on wxGTK to work around the fact that GTK requires the locale
 241 to be set to the system settings but Python depends on LC_NUMERIC
 242 remaining compatible with &quot;C&quot;.</p>
 243 <p>Switched gizmos.TreeListCtrl to the newer version of the code from the
 244 wxCode project.</p>
 245 <p>OGL is dead! LONG LIVE OGL!  (Oops, sorry.  A bit of my dramatic side
 246 leaked out there...)  The wx.ogl module has been deprecated in favor
 247 of the new Python port of the OGL library located at wx.lib.ogl
 248 contributed by Pierre Hjälm.  This will hopefully greatly extend the
 249 life of OGL within wxPython by making it more easily maintainable and
 250 less prone to getting rusty as there seems to be less and less
 251 interest in maintaining the C++ version.  At this point there are just
 252 a couple minor known compatibility differences, please see the
 253 <a class="reference" href="MigrationGuide.html">MigrationGuide</a> file for details.</p>
 254 <p>EVT_STC_POSCHANGED has been removed as it has been deprecated in
 255 Scintilla for several releases now.</p>
 256 <p>All the Window and GDI (pen, bitmap, etc.) class constructors and also
 257 many toplevel functions and static methods will now check that a
 258 wx.App object has already been created and will raise a
 259 wx.PyNoAppError exception if not.</p>
 260 <p>Added more default args as needed to allow most window types to be
 261 constructed with only the parent window arg.  In some cases other args
 262 may be required for normal operation, but they can usually be set
 263 after construction.</p>
 264 <p>Removed the deprecated ErrorDialogs and PythonBitmaps modules.  If you
 265 were using these in your apps then please join wxPython-dev and assist
 266 with a more modern reimplementation.</p>
 267 <p>Added a new version (0.8.3) of FloatCanvas from Chris Barker.  It's now
 268 in a subpackage of wx.lib.</p>
 269 <p>It is now possible to change the tab traversal order of controls on a
 270 panel or dialog.  For details see the new MoveAfterInTabOrder and
 271 MoveBeforeInTabOrder methods of wx.Window.</p>
 272 <p>Applied (and heavily modified) a patch from Eugene
 273 &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
 274 edited and reloaded, all from within the demo.  You can switch back
 275 and forth between the default and your edited version, and any errors
 276 ocurring upon the reload are reported on the Demo tab.</p>
 277 <p>Added a menu item in the demo that will open a PyShell window that has
 278 the app and demo frame preloaded in the namespace.  This is another
 279 good way to explore and play with the objects in the currently running
 280 sample.  For example, load the Button sample and then do the following
 281 in the PyShell:</p>
 282 <pre class="literal-block">
 283 &gt;&gt;&gt; b = frame.demoPage.GetChildren()[0]
 284 &gt;&gt;&gt; for x in range(0, 500, 10):
 285 ...     b.Move((x, 50))
 286 ...     app.Yield(True)
 287 ...     wx.MilliSleep(10)
 288 </pre>

 291 <h1><a name="id4">2.5.1.5</a></h1>
 292 <p>(See also the <a class="reference" href="MigrationGuide.html">MigrationGuide</a> file for details about some of the
 293 big changes that have happened in this release and how you should
 294 adapt your code.)</p>
 295 <p>The wxWindows project and library is now known as wxWidgets.  Please
 296 see <a class="reference" href="http://www.wxwindows.org/name.htm">http://www.wxwindows.org/name.htm</a> for more details.  This won't
 297 really affect wxPython all that much, other than the fact that the
 298 wxwindows.org domain name will be changing to wxwidgets.org, so mail
 299 list, CVS, and etc. addresses will be changing.  We're going to try
 300 and smooth the transition as much as possible, but I wanted you all to
 301 be aware of this change if you run into any issues.</p>
 302 <p>Many, many little fixes, changes and additions done as part of the move
 303 to wxWidgets 2.5 that I have forgotten about.</p>
 304 <p>Added wxMirrorDC.</p>
 305 <p>Added wxIconLocation</p>
 306 <p>Added Python wrappers and demos for the new wxVScrolledWindow,
 307 wxVListBox, and wxHtmlListBox classes.</p>
 308 <p>Added wrappers for wxBookCtrl and wxListbook.  wxNotebook now derives
 309 from wxBookCtrl.</p>
 310 <p>Added Gordon Williams' PyPlot module to the library, available as the
 311 wx.lib.plot module.</p>
 312 <p>I made a small but important change in the code that aquires the
 313 Python Global Interpreter Lock to try and prevent deadlocks that can
 314 happen when there are nested attempts to aquire the GIL.</p>
 315 <p>The RPMs will now install menu items on Mandrake Linux in
 316 Applications/Development/Tools for PyCrust, XRCed, etc.  The RPMs are
 317 also installing icons and <tt class="literal"><span class="pre">*.desktop</span></tt> items in the generic KDE and
 318 GNOME locations, but I don't know yet if they are resulting in menu
 319 items on non-Mandrake systems.  (It didn't automatically do it on my
 320 RH-9 build box but I didn't chase it very far...)  If you have ideas
 321 for how to improve the .spec file to work better and/or on more
 322 distros please send me a patch.</p>
 323 <p>The RPMs are now built on a fairly generic RH-9 box, and I have tested
 324 installing them also on my main Mandrake 9.2 box.</p>
 325 <p>There are some big changes in the OS X disk image.  The actual
 326 Installer package now <em>only</em> installs the wxMac dynlibs, wxPython
 327 extension modules and Python packages, and also the command-line tool
 328 scripts. The remaining items (demo, samples, and application bundles
 329 for the Demo, PyCrust and XRCed) are now top-level items in the disk
 330 image (.dmg file) that users can just drag and drop to wherever they
 331 want to put them.</p>
 332 <p>The wxWave class has been renamed to wxSound, and now has a slightly
 333 different API.</p>
 334 <p>Updated the AnalogClockWindow with many enhancements from E. A. Tacão.</p>
 335 <p>wxMac now has wx.ToggleButton!</p>
 336 <p>wx.stc.StyledTextCtrl has been updated to version 1.58 of Scintilla.</p>
 337 <p>To help with the wx.stc.StyledTextCtrl performance issues on wxMac
 338 I've added a SetUseAntiAliasing method (and GetUseAntiAliasing too)
 339 that will turn off the use of antialiased fonts in the wxSTC, allowing
 340 it to bypass the slow text measuring routines and use the fast and
 341 simple one instead.  By default the setting is turned off (on wxMac
 342 only.)  When run on OSX the Py* apps have a new item on the Options
 343 menu for controlling this setting if you would like to experiment with
 344 it.</p>
 345 <p>Updated wx.lib.calendar with many fixes and enhancements from Joerg
 346 &quot;Adi&quot; Sieker.</p>
 347 <p>Added wx.Display and wx.VideoMode.</p>
 348 <p>AppleEvents can be handled by overriding wx.App methods MacOpenFile,
 349 MacPrintFile, MacNewFile, and MacReopenApp.</p>
 350 <p>Added wx.PlatformInfo which is a tuple containing strings that
 351 describe the platform and build options of wxPython.  See the
 352 MigrationGuide for more details.</p>
 353 <p>Created a new extension module &quot;activex&quot; from Lindsay Mathieson's
 354 newest <a class="reference" href="http://members.optusnet.com.au/~blackpaw1/wxactivex.html">wxActiveX</a> class.  (The existing iewin module used an older
 355 version of this code, but only exposed the wxIEHtmlWin class.)  This
 356 new module will (in theory ;-) ) allow you to host arbitrary ActiveX
 357 controls in a wx.Window, <strong>without</strong> requiring the use of the win32com
 358 and other PyWin32 modules!  This should eliminate the cronic problems
 359 that have resulted from minor mismatches in how PyWin32 handles the
 360 GIL and tstate when making callbacks, etc.  The older iewin module
 361 will be left in this release as the new stuff is not fully backwards
 362 compatible, but you should migrate your code to the new IEHtmlWindow
 363 in wx.lib.iewin, so the old one can be eventually removed.
 364 Additionally, I've always considered that the wx.lib.activexwrapper
 365 module is an ugly hack that I only included in the lib because I
 366 couldn't figure out anything better.  Well now we have something that,
 367 if it isn't already, has the potential to be better.  So consider
 368 migrating away from using activexwrapper as well.  Please see the
 369 MigrationGuide for more details on using the new module.</p>
 370 <p>Floats are allowed again as function parameters where ints are expected.</p>
 371 </div>
 372 <div class="section" id="id6">
 373 <h1><a name="id6">2.4.2.4</a></h1>
 374 <p>Use wxSTC in the demo for displaying the soucre code of the samples.</p>
 375 <p>Lots of bug fixes and such from the wxWindows folks.</p>
 376 <p>Added wxPython.lib.newevent from Miki Tebeka.  Its usage is
 377 demonstrated in the Threads sample in the demo.</p>
 378 <p>Updates to wxMaskedEditCtrl.</p>
 379 <p>Added wxMaskedNumCtrl.</p>
 380 <p>Added Chris Barker's FloatCanvas.</p>
 381 </div>
 382 <div class="section" id="id7">
 383 <h1><a name="id7">2.4.1.2</a></h1>
 384 <p>Added wxScrolledPanel from Will Sadkin</p>
 385 <p>Added SetShape method to top level windows (e.g. wxFrame.)</p>
 386 <p>Changed wxSWIG to not generate Python code using apply, (since it will
 387 be deprecated in the future) wxSWIG will use <tt class="literal"><span class="pre">spam(*args,</span> <span class="pre">**kw)</span></tt> syntax
 388 instead.  Also changed the generated __repr__ methods to be a bit more
 389 informative.</p>
 390 <p>Made the version number information more robust and uh, informative.
 391 Also added asserts to check that the major.minor versions of wxPython
 392 and wxWindows match.</p>
 393 <p>Added the new wx &quot;renamer&quot; package that will dynamically import from
 394 the wxPython package and rename wxFooBar --&gt; FooBar.  That means that
 395 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
 396 wx.Frame instead of wx.wxFrame.  This is phase 1 of a full transition
 397 to the new namespace.</p>
 398 <p>Updated Scintilla to 1.52.  I also changed it to use wxListCtrl
 399 instead of wxListBox for the AutoComplete window, added the ability to
 400 use custom bitmaps in the margin and in the AutoComplete windows, and
 401 worked out how to do proper clipping of child windows on wxGTK.</p>
 402 <p>Patrick O'Brien's PyCrust package has been renamed to Py and now
 403 includes several new tools.  As part of the change the location of the
 404 pacakge has changed as well, it is now accessible as &quot;from wxPython
 405 import py&quot; (or &quot;from wx import py&quot; using the new namespace.)  There
 406 are still some transition modules in the wxPython.lib.PyCrust package
 407 that will issue a warning and then import what is needed from the new
 408 package.  These will be removed in a future release.</p>
 409 <p>Added __nonzero__ method to wxTreeItemId, wxBitmap, wxImage, wxFont,
 410 and most other classes that have an Ok or IsOK method.  This allows
 411 code like &quot;if obj: ...&quot; to be the same as &quot;if obj.IsOk(): ...&quot;</p>
 412 <p>Toolbars on wxMac can now have controls on them.</p>
 413 <p>Added wxPython.lib.analogclock module based on samples that were
 414 passed back and forth on wxPython-users a while back.</p>
 415 <p>Added masked edit controls (wxPython.lib.maskededit) by Jeff Childers
 416 and Will Sadkin.  Updated wxTimeCtrl to use MaskedEdit.</p>
 417 <p>When the __class__ of a dead object is replaced with _wxPyDeadObject
 418 the __del__ of the original class is now called first.</p>
 419 <p>Added wxTreeListCtrl.  (Looks like a wxTreeCtrl embedded in a
 420 wxListCtrl, but actually is just giving multiple columns to a
 421 wxTreeCtrl.)</p>
 422 <p>Added wxFutureCall, a subclass of wxTimer that makes it easy to delay
 423 a call to any Python callable object.</p>
 424 <p>Added wxPy versions of wxPrintPreview, wxPreviewFrame, and
 425 wxPreviewControlBar so they can be derived from in Python and be able
 426 to override the C++ virtual methods.</p>
 427 <p>Simplified how the wxSizer methods are wrapped, changed the name of
 428 the &quot;option&quot; parameter to &quot;proportion&quot; to match the docs (&quot;option&quot; is
 429 still accepted for compatibility, but this will go away in a future
 430 release,) SetItemMinSize can now take a wxSize (or 2-tuple) parameter,
 431 and Spacers can be specified with a wxSize (or 2-tuple) parameter</p>
 432 <p>Added wxCursorFromBits.</p>
 433 </div>
 434 <div class="section" id="id8">
 435 <h1><a name="id8">2.4.0.7</a></h1>
 436 <p>Gave up on generating a warning upon the use of the old true/false or
 437 TRUE/FALSE values.</p>
 438 <p>Fixed wxGenericTreeCtrl (used on wxGTK and wxMac for wxTreeCtrl) so
 439 that it can successfully handle lots of nodes instead of overflowing
 440 when the virtual height of the widget overflowed a 16-bit value.</p>
 441 <p>Fixed the typemap that converts strings to wxColours to also accept
 442 unicode.</p>
 443 <p>Fixed problem where the wrong class name could sometimes be used for
 444 OOR.</p>
 445 <p>Fixed an interpreter lock problem in the __eq__ and __ne__ methods in
 446 wxSize and etc.</p>
 447 <p>Updated PyCrust to version 0.9</p>
 448 <p>Instead of always logging C++ assertions, added wxPYAPP_ASSERT_LOG
 449 flag to turn it on.  In most cases turning it into an exception (the
 450 default behavior) is enough.  See below in the 2.3.4.1 notes for more
 451 details.</p>

 454 <h1><a name="a-k-a-the-i-m-so-stupid-release">2.4.0.6 (a.k.a. the I'm so stupid release)</a></h1>
 455 <p>The new deprecation class for the old true/false symbols can now be
 456 returned from OnInit.  And I promise to be sure I am testing what I
 457 think I am testing in the future...</p>

 462 <p>Updated pycolourchooser.</p>
 463 <p>Updated to 0.9b of PyCrust.</p>
 464 </div>
 465 <div class="section" id="id9">
 466 <h1><a name="id9">2.4.0.4</a></h1>
 467 <p>Added missing wxRect methods</p>
 468 <p>Add OOR support for wxApp objects too.</p>
 469 <p>Added wxCursorFromImage, which works on wxMSW and wxGTK so far.</p>
 470 <p>All platforms now send EVT_DESTROY_WINDOW.  Be warned that at the time
 471 the event is sent the window is in the process of being deconstructed,
 472 and so calling some (most?) methods of the window itself may cause
 473 problems.</p>
 474 <p>Fixed SF Bug #689481, a method in the OGL wrappers was using the wrong
 475 return type.</p>
 476 <p>Fixed SF Bug #689958, an endless loop in printout.py.</p>
 477 <p>Added EVT_WINDOW_CREATE_ID and EVT_WINDOW_DESTROY_ID so these events
 478 can be associated with a specific window ID and more easily caught by
 479 the parent window.</p>
 480 <p>Fixed copy-paste error in wxListCtrl.GetFirstSelected.</p>
 481 <p>Added missing Init method (and an overloading wrapper) to wxLocale
 482 wrapper.</p>
 483 <p>Added a wxBitmap.SetMaskColour convenience method.</p>
 484 <p>Changed how the dynamic event tables (used for all Python wx classes,
 485 C++ wx classes typically use static event tables) are searched such
 486 that they behave from a Python perspective more like the static tables
 487 in C++.  Namely that if there are identical event bindings in a base
 488 Python class and a derived Python class that the one in the derived
 489 class will be found first and that if Skip is called that the one in
 490 the base class will still be found instead of skipping directly to the
 491 static stable in the C++ class.</p>
 492 <p>Switched to using True/False in the wxPython lib and demo instead of
 493 true/false or TRUE/FALSE to prepare for the new boolean type and
 494 constants being added to Python.  Added code to wx.py to test for the
 495 existence of the new constants and to create suitable values if not
 496 present.</p>
 497 <p>Added some static wxApp functions that help with integration with the
 498 Mac UI.  They are no-ops on other platforms so it doesn't hurt to
 499 always call them.  The functions are:</p>
 500 <blockquote>
 501 wxApp_GetMacDefaultEncodingIsPC
 502 wxApp_GetMacSupportPCMenuShortcuts
 503 wxApp_GetMacAboutMenuItemId
 504 wxApp_GetMacPreferencesMenuItemId
 505 wxApp_GetMacExitMenuItemId
 506 wxApp_GetMacHelpMenuTitleName
 507 wxApp_SetMacDefaultEncodingIsPC
 508 wxApp_SetMacSupportPCMenuShortcuts
 509 wxApp_SetMacAboutMenuItemId
 510 wxApp_SetMacPreferencesMenuItemId
 511 wxApp_SetMacExitMenuItemId
 512 wxApp_SetMacHelpMenuTitleName</blockquote>
 513 <p>Refactored, enhanced and added capabilities for the DrawXXXList
 514 functions, inspired by code from Chris Barker.</p>
 515 <p>The wxWindows .mo language catalog files are now installed in a
 516 subdirectory of the wxPython package dir on MSW since that platform
 517 doesn't have a standard place for them.</p>
 518 <p>Added missing deselect methods for wxGrid.</p>
 519 <p>Fixed typemaps for wxGridCellCoordsArray.</p>
 520 <p>Updated to the 0.9a version of PyCrust</p>
 521 </div>

 541 <p>Updated XRCed and wxTimeCtrl contribs.</p>
 542 <p>Show a couple new wxGrid features in the demo.</p>
 543 <p>Several bug fixes in wxWindows.</p>
 544 <p>Added wxHtmlFilter.</p>
 545 <p>wxASSERT and related C++ runtime diagnostics are now converted to
 546 Python exceptions.  When an assert happens a wxPyAssertionError
 547 (which derives from AssertionError) exception is created and when
 548 control returns back to the Python code that invoked the C++ API it
 549 will be raised.  The same exception restrictions are in place as
 550 before, namely that exceptions can't cross from one Python layer
 551 through C++ to another Python layer.  That simply means that if you
 552 want to catch wxPyAssertionError or any other exception that you need
 553 to do it before control returns to C++ at the end of your event
 554 handler or callback code.  There is some test code in demo/wxButton.py
 555 you can use to play with this new feature.</p>
 556 <p>Added some methods to wxApp (SetAssertMode and GetAssertMode) that let
 557 you control how C++ assertions are processed.  Valid modes are:
 558 wxPYAPP_ASSERT_SUPPRESS, wxPYAPP_ASSERT_EXCEPTION, and
 559 wxPYAPP_ASSERT_DIALOG.  Using _SUPPRESS will give you behavior like
 560 the old &quot;final&quot; builds and the assert will be ignored, _EXCEPTION is
 561 the new default described above, and _DIALOG is like the default in
 562 2.3.3.1 and prior &quot;hybrid&quot; builds.  You can also combine _EXCEPTION
 563 and _DIALOG if you wish, although I don't know why you would.</p>
 564 <p>You can now overload OnInitGui, OnExit and OnAssert in your classes
 565 derived from wxApp.</p>
 566 <p>Added GetSelectedCells, GetSelectionBlockTopLeft,
 567 GetSelectionBlockBottomRight, GetSelectedRows, GetSelectedCols nethods
 568 to wxGrid.</p>
 569 <p>Added Python == and != operators for some basic classes</p>
 570 <p>Fixed the Python wrappers for wxInputStream so they no longer block
 571 when reading from a wxProcess on wxGTK.  They now work more or less as
 572 they did before 2.3.3.1 but the dual meaning of eof() has been
 573 removed.  There is now a CanRead() method that lets you know if there
 574 is data waiting to be read from the pipe.</p>
 575 <p>Fixed method name clash in wxIEHtmlWin, renamed Refresh to RefreshPage.</p>
 576 <p>Added Throbber from Cliff Wells to the library and the demo.</p>
 577 <p>Windows installer prompts to uninstall old version first.</p>
 578 <p>Added wxPython.lib.evtmgr by Robb Shecter, which is an easier, more
 579 &quot;Pythonic&quot; and more OO method of registering handlers for wxWindows
 580 events using the Publish/Subscribe pattern.</p>
 581 <p>Added wxPython.lib.popupctl by Gerrit van Dyk which is a combobox-like
 582 gizmo for poping up arbitrary controls.  It is currently using
 583 wxDialog because of some issues with wxPopupWindow...</p>
 584 <p>Added wxPython.lib.gridmovers by Gerrit van Dyk which facilitates the
 585 dragging of columns and/or rows in a wxGrid.</p>
 586 <p>Added wxPython.lib.multisash by Gerrit van Dyk which is a nice
 587 implementation of allowing the user to split a window any number of
 588 times either horizontally or vertically, and to close the split off
 589 windows when desired.</p>
 590 <p>Added helpviewer tool that displays HTML books similarly to how MS
 591 HTMLHelp viewer does.  Changed how the wxPythonDocs tarball is built
 592 and added a script to launch the doc viewer.</p>
 593 </div>
 594 <div class="section" id="id14">
 595 <h1><a name="id14">2.3.3.1</a></h1>
 596 <p>Added wxSplashScreen.</p>
 597 <p>Added wxGenericDirCtrl.</p>
 598 <p>Added wxMultiChoiceDialog.</p>
 599 <p>The calltip window and autocomplete window in wxSTC will now use a
 600 wxPopupWindow if available on the platform (and functioning correctly)
 601 so they can extend beyond the client area of the STC if needed.</p>
 602 <p>Finished wrapping and providing typemaps for wxInputStream and also
 603 added the stream ctor and other methods for wxImage so images can now
 604 be loaded from any Python &quot;file-like&quot; object.</p>
 605 <p>Changed the img2py tool to use PNG instead of XPM for embedding image
 606 data in Python source code, and the generated code now uses streams to
 607 convert the image data to wxImage, wxBitmap, or wxIcon.</p>
 608 <p>Added the wxPython.lib.rcsizer module which contains RowColSizer.
 609 This sizer is based on code from Niki Spahiev and lets you specify a
 610 row and column for each item, as well as optional column or row
 611 spanning.  Cells with no item assigned to it are just left blank.
 612 Stretchable rows or columns are specified and work the same as in
 613 wxFlexGridSizer.</p>
 614 <p>Updated XRCed from Roman Rolinsky</p>
 615 <p>Added wxBufferedDC.</p>
 616 <p>Upgraded wxSTC from Scintilla 1.40 to Scintilla 1.45, and then again
 617 to version 1.47, and one more time to 1.48! &lt;wink&gt;</p>
 618 <dl>
 619 <dt>UNICODE!</dt>
 620 <dd><p class="first">wxWindows/wxPython can be compiled with unicode support enabled or
 621 disabled.  Previous to wxPython 2.3.3 non-unicode mode was always
 622 used.  Starting with 2.3.3 either mode is supported, but only if
 623 it is also available in wxWindows on the platform.  Currently
 624 wxWindows only supports unicode on MS Windows platforms, but with
 625 the recent release of GTK+ 2.0 it is only a matter of time until
 626 it can be done on wxGTK (Linux and other unixes) as well.</p>
 627 <p>Unicode works best on platforms in the NT branch of the Windows
 628 family tree (NT, win2k, XP) but it is now also possible to use the
 629 same unicode binaries on win95/98/ME platforms as well!  This is
 630 done by using a special library and DLL with the application
 631 called MSLU, (Microsoft Layer for Unicode).  It simply gets out of
 632 the way if the app is run on an NT box, otherwise if run on a
 633 win9x box it loads a special DLL that provides the unicode
 634 versions of the windows API.  So far I have not been able to get
 635 this to work perfectly on win9x.  Most things work fine but
 636 wxTaskBarIcon for example will cause a crash if used with the
 637 unicode build on win95.</p>
 638 <p class="last">So how do you use it?  It's very simple.  When unicode is enabled,
 639 then all functions and methods in wxPython that return a wxString
 640 from the C++ function will return a Python unicode object, and
 641 parameters to C++ functions/methods that expect a wxString can
 642 accept either a Python string or unicode object.  If a string
 643 object is passed then it will be decoded into unicode using the
 644 converter pointed to by wxConvCurrent, which will use the default
 645 system encoding.  If you need to use a string in some other
 646 encoding then you should convert it to unicode using the Python
 647 codecs first and then pass the unicode string to the wxPython
 648 method.</p>
 649 </dd>
 650 </dl>
 651 <p>Added wxListCtrlAutoWidthMixin from Erik Westra.</p>
 652 <p>Added wxIconBundle and wxTopLevelWindow.SetIcons.</p>
 653 <p>Added wxLocale and wxEncodingConverter.</p>
 654 <p>A little black magic...  When the C++ object (for a window or
 655 whatever) is deleted there is no way to force the Python shadow object
 656 to also be destroyed and clean up all references to it.  This leads to
 657 crashes if the shadow object tries to call a method with the old C++
 658 pointer.  The black magic I've done is to replace the __class__ in the
 659 Python instance object with a class that raises an exception whenever
 660 a method call (or other attribute access) is attempted.  This works
 661 for any class that is OOR aware.</p>
 662 <p>Added OOR support for wxGridCellRenderer, wxGridCellEditor,
 663 wxGridCellAttr, wxGridCellAttrProvider, wxGridTableBase and their
 664 derived classes.</p>
 665 <p>Added wxImage.GetDataBuffer which returns an in-place edit buffer of
 666 the image data.  (Patch #546009)</p>
 667 <p>Added a sample that shows how to embed wxPython in a wxWindows C++
 668 application.</p>
 669 <p>Added wxPyWindow, wxPyPanel and wxPyControl which are just like their
 670 wx counterparts except they allow some of the more common C++ virtual
 671 methods to be overridden in Python derived classes.  The methods
 672 supported are:</p>
 673 <blockquote>
 674 <p>DoMoveWindow
 675 DoSetSize
 676 DoSetClientSize
 677 DoSetVirtualSize
 678 DoGetSize
 679 DoGetClientSize
 680 DoGetPosition
 681 DoGetVirtualSize
 682 DoGetBestSize
 683 InitDialog
 684 TransferDataFromWindow
 685 TransferDataToWindow
 686 Validate
 687 AcceptsFocus
 688 AcceptsFocusFromKeyboard
 689 GetMaxSize
 690 AddChild
 691 RemoveChild</p>
 692 <p>If there are other methods that you think should be supported
 693 please let me know.</p>
 694 </blockquote>
 695 <p>Changed wxGenButton to derive from wxPyControl and overload
 696 DoGetBestSize and AcceptsFocus.</p>
 697 <p>Added wxArtProvider.</p>
 698 <p>Added wxCallAfter which is a helper function that registers a function
 699 (or any callable Python object) to be called once the next time there
 700 are no pending events.  This is useful for when you need to do
 701 something but it can't be done during the current event handler.  The
 702 implementation is very simple, see wxPython/wx.py.</p>
 703 <p>Fixed a boatload of reference leaks.</p>
 704 <p>Added a demo of using a sizer in a wxScrolledWindow, in effect
 705 creating a ScrolledPanel.</p>
 706 <p>Added a sample to the demo that shows how to use radio menu items, and
 707 other menu stuff.</p>
 708 <p>Added wxIEHtmlWin.  This is essentially the same as using IE with the
 709 ActiveXWrapper already in the library, but it is implemented all in
 710 C++ and therefore does not need any of the modules from win32all and
 711 so it is less fragile in the face of changes.</p>
 712 <p>Fixed the ActiveXWrapper problem.  Looks like when the win32com
 713 modules make a &quot;callback&quot; that they (incorrectly, IMHO) allocate a
 714 transient thread state structure.  Since wxPython is now saving
 715 tstates for it's own callbacks it ended up using garbage after
 716 win32com got rid of the temporary tstate...</p>
 717 <p>Added a generic static text control to wxPython.lib.stattext.  This is
 718 so things like Boa and PythonCard can have a static text that can
 719 respond to mouse events and etc.</p>
 720 <p>Changed the wxDateTime.Parse* methods to return an int that will be -1
 721 on failure, and the index where parsing stopped otherwise.</p>
 722 <p>Moved tools to be a Python package in wxPython.tools, added scripts to
 723 import and launch each tool.  This will let you import and use the
 724 tools in your own scripts or apps as needed.  On Linux and OS X the
 725 tool scripts are installed to {prefix}/bin so you should be able to
 726 easily launch them from the command line.  For example, PyCrust can be
 727 started with just the &quot;pycrust&quot; command.</p>
 728 <p>Added a sample to the demo that catches various key events and
 729 displays the details of the event.</p>
 730 <p>Added wxWizard, wxWizardPage, wxWizardPageSimple and wxPyWizardPage.</p>
 731 <p>Added wxXmlResourceHandler which allows you to create custom handlers
 732 for nonstandard class types in XRC resources.  See the demo for an
 733 example.</p>
 734 <p>Added wxPython.lib.mixins.rubberband module from Robb Shecter.</p>
 735 <p>Added wxTimeCtrl from Will Sadkin.</p>
 736 </div>
 737 <div class="section" id="id15">
 738 <h1><a name="id15">2.3.2.1</a></h1>
 739 <p>Changed (again) how the Python global interpreter lock is handled as
 740 well as the Python thread state.  This time it works on SMP machines
 741 without barfing and is also still compatible with Python debuggers.</p>
 742 <p>Added some patches from library contributors.</p>
 743 </div>
 744 <div class="section" id="id16">
 745 <h1><a name="id16">2.3.2</a></h1>
 746 <p>Added EVT_HELP, EVT_HELP_RANGE, EVT_DETAILED_HELP,
 747 EVT_DETAILED_HELP_RANGE, EVT_CONTEXT_MENU, wxHelpEvent,
 748 wxContextMenuEvent, wxContextHelp, wxContextHelpButton, wxTipWindow,
 749 and a demo to show them in action.</p>
 750 <p>Deprecated PyShell and PyShellWindow, added a snapshot of PyCrust (see
 751 <a class="reference" href="http://sourceforge.net/projects/pycrust/">http://sourceforge.net/projects/pycrust/</a>. )</p>
 752 <p>Added the new virtual list capabilities to wxListCtrl.</p>
 753 <p>Added a wxSTC style editor from Riaan Booysen to the sample apps.</p>
 754 <p>Added XRCed to the wxPython Tools directory, contributed by Roman
 755 Rolinsky.</p>
 756 <p>Added a new &quot;constructor&quot; to most of the window classes that calls the
 757 default C++ constructor, (the one with no parameters) and also added the
 758 corresponding  Create(...) method.  This allows you to do a 2-step
 759 creation of windows which is sometimes required for doing things such
 760 as setting extended style flags before the window is created, or for
 761 passing the object to the XRC resource system to be created from the
 762 resource.  The name of the new &quot;constructor&quot; is the original name of
 763 the class with a &quot;Pre&quot; in it.  For example, wxPreWindow, wxPreFrame,
 764 etc.</p>
 765 <p>Updated to version 1.40 of Scintilla and updated wxStyledTextCtrl
 766 accordingly.  While doing this update I dropped the wxLB_SORT style
 767 from the wxListBox created for the AutoComplete functionality.  This
 768 means that you will have to sort the keyword lists yourself, but you
 769 are free to do case sensitive or case insensitive sorts and set the
 770 wxSTC flag accordingly.</p>
 771 <p>Updated wxColumnSorterMixin to also be able to place sort icons on the
 772 column headers, and updated the wxListCtrl demo to show it off by
 773 using wxColumnSorterMixin.</p>
 774 <p>Added wxGenBitmapTextButton, TablePrint, etc. contribs from Lorne White.</p>
 775 <p>Added wxNativeFontInfo and wxFontMapper.</p>
 776 <p>Added pySketch to the samples.</p>
 777 <p>Significantly changed how the Python interpreter lock and thread state
 778 are managed, which should fix the problem of running on a
 779 multi-processor machine.</p>
 780 <p>Added wxPyLog so log targets can be created in Python to handle log
 781 messages however is wished.  See demo/Main.py for an example.</p>
 782 <p>Added wxFindReplaceDialog.</p>
 783 <p>The second phase of OOR is implemented for wxEvtHandler, wxSizer,
 784 wxShape and derived classes.  This means that functions and methods
 785 that return an object derived from wxEvtHandler that was originally
 786 created in Python, will return the original Python object (if it still
 787 exists) instead of letting SWIG wrap a new shadow object around the
 788 original C++ pointer.</p>
 789 <p>Added some optimization methods to wxDC: GetBoundingBox, DrawLineList,
 790 DrawPointList.</p>
 791 <p>Added a set of sophisticated Error Dialogs from Chris Fama.</p>
 792 <p>Added wxRightTextCtrl from Josu Oyanguren to wxPython.lib for aligning
 793 text in a wxTextCtrl to the right side.</p>
 794 <p>Added wxURLDataObject and an example showing drag and drop of URLs to
 795 and from web browsers.  It's still not 100% bullet-proof for all types
 796 of browsers, but it works for the majority of cases with the popular
 797 browsers on Windows.  On wxGTK it seems that only Netscape 4.x works,
 798 if anybody has any suggestions about this please bring it up on the
 799 wx-dev list.</p>
 800 <p>Added wxStopWatch.</p>
 801 <p>Added wxMimeTypesManager and wxFileType.</p>
 802 <p>Passing None for the handler parameter to one of the EVT_** functions
 803 will now Disconnect the event.</p>
 804 <p>Added wxPopupWindow and wxPopupTransientWindow.</p>
 805 <p>Added wxFileHistory.</p>
 806 <p>Added wxDynamicSashWindow, which allows you to endlessly split windows
 807 by dragging a little tab next to the scrollbars.  Added a demo to show
 808 this and also the ability of multiple wxStyledTextCtrls to share the
 809 same document.</p>
 810 <p>Added wxEditableListBox gizmo.</p>
 811 <p>Updated wxEditor with lots of enhancements from Steve Howell and Adam
 812 Feuer.</p>
 813 <p>Added the &quot;SplitTree gizmos&quot; which are a collection of classes that
 814 were designed to operate together and provide a tree control with
 815 additional columns for each item.  The classes are
 816 wxRemotelyScrolledTreeCtrl, wxTreeCompanionWindow,
 817 wxThinSplitterWindow, and wxSplitterScrolledWindow, some of which may
 818 also be useful by themselves.</p>
 819 <p>Added wxDllWidget from Vaclav Slavik which allows wx widgets derived
 820 from wxWindow to be loaded from a C++ .dll (or .so) and be used in a
 821 wxPython program, without the widget having to be SWIGged first.  The
 822 visible API of the widget is limited to wxWindow methods plus a
 823 SendCommand method, but it is still quite powerful.  See
 824 wxPython/contrib/dllwidget and wxPython/demo/dllwidget for more
 825 details.</p>
 826 </div>
 827 <div class="section" id="id17">
 828 <h1><a name="id17">2.3.1</a></h1>
 829 <p>Added EVT_GRID_EDITOR_CREATED and wxGridEditorCreatedEvent so the user
 830 code can get access to the edit control when it is created, (to push
 831 on a custom event handler for example.)</p>
 832 <p>Added wxTextAttr class and SetStyle, SetDefaultStyle and
 833 GetDefaultStyle methods to wxTextCtrl.</p>
 834 <p>Added ability to use xml resource files.  Still need to add ability to
 835 subclass wxXmlResourceHandler, etc...</p>
 836 <p>Added wxGridAutoEditMixin to the mixins library package.</p>
 837 <p>Made ColourSelect be derived from wxButton.</p>
 838 <p>Fixed img2py to work correctly with Python 2.1.</p>
 839 <p>Added enhanced wxVTKRenderWindow by Prabhu Ramachandran</p>
 840 </div>
 841 <div class="section" id="id18">
 842 <h1><a name="id18">2.3.0</a></h1>
 843 <p>Removed initial startup dependency on the OpenGL DLLs so only the
 844 glcanvasc.pyd depends on them, (on wxMSW.)</p>
 845 <p>Changed wxFont, wxPen, wxBrush to not implicitly use the
 846 wxThe[Font|Pen|Brush]List objects behind the scenes, but to use normal
 847 ctor and dtors.</p>
 848 <p>Exposed the wxThe[Font|Pen|Brush]List to wxPython.</p>
 849 <p>Also added wxTheColourDatabase and added a library module (in the
 850 wxPython.lib.colourdb module) to load LOTS more colour names into the
 851 colour database.</p>
 852 <p>Added wxWakeUpMainThread, wxMutexGuiEnter, wxMutexGuiLeave,
 853 wxMutexGuiLocker and wxThread_IsMain to assist with dealing with GUI
 854 access from non-GUI threads.</p>
 855 <p>wxPyOnDemandOutputWindow is now (more) thread safe if non-GUI threads
 856 use print, sys.stdout.write, etc.</p>
 857 <p>Added CreateTextSizer and CreateButtonSizer to wxDialog</p>
 858 <p>Added wxPython/lib/infoframe.py from Chris Fama.  It contains a class
 859 that can be used in place of wxPyOnDemandOutputWindow.</p>
 860 <p>Added colourselect.py, imagebrowser.py and an updated calendar.py to
 861 wxPython/lib from Lorne White.</p>
 862 <p>Added patch to wxPoint_LIST_helper from Tim Hochberg that should make
 863 it gobs faster in certain situations.</p>
 864 <p>Added tools that will take an image file in a wx supported format and
 865 convert it to data embedded in a Python source file.  The image is
 866 converted to XPM format which is essentially a list of strings
 867 containing info about each pixel.  The image's transparency mask is
 868 included, if there is one, or a mask can be added if a mask colour is
 869 specified on the command line.  It is then pickled and optionally
 870 compressed and written to a Python source file along with functions to
 871 convert it to either a wxBitmap or a wxImage.  See
 872 wxPython/demo/images.py for examples, and wxPython/Tools/img2py.py for
 873 the implementation.</p>
 874 <p>Fixed wxStyledTextCtrl to be much faster on wxGTK.  There was some
 875 experimental code that got left in place that ended up causing way too
 876 many refreshes.</p>
 877 <p>A couple more hacks in my_distutils.py so wxPython can be built with
 878 the distutils that comes with Python 2.1.</p>
 879 <p>Added a ton of missing methods for wxPrintData.</p>
 880 <p>Switched to InnoSetup for MSW distributions.</p>
 881 <p>Added wxToggleButton.</p>
 882 <p>Fixed bug that prevented wxTreeCtrl.OnCompareItems from being called.</p>
 883 <dl>
 884 <dt>Added some methods to wxGrid:</dt>
 885 <dd>GetCellHighlightPenWidth
 886 GetCellHighlightROPenWidth
 887 SetCellHighlightPenWidth
 888 SetCellHighlightROPenWidth
 889 GetGridWindow
 890 GetGridRowLabelWindow
 891 GetGridColLabelWindow
 892 GetGridCornerLabelWindow</dd>
 893 </dl>
 894 <p>Added wxGetClientDisplayRect which on wxMSW returns a wxRect
 895 representing the area on screen not occupied by the taskbar and such.
 896 On other platforms it is equivallent to wxGetDisplaySize.</p>
 897 <dl>
 898 <dt>OOR:</dt>
 899 <dd><p class="first">Implemented the first phase of OOR (Original Object Return).  See
 900 the text in the demo for more details of what this means, but in a
 901 nutshell methods such as wxWindow.GetParent or FindWindowById will
 902 now return a shadow object of the proper type if it can.  By
 903 &quot;proper type&quot; I mean that if the wxWindow pointer returned from
 904 FindWindowById really points to a wxButton then the Python object
 905 constructed will be of a wxButtonPtr class instead of wxWindowPtr
 906 as before.  This should reduce or eliminiate the need for
 907 wxPyTypeCast.  (Woo Hoo!)  The objects returned are still not the
 908 original Python object, but that is the next step.  (Although it
 909 will probably only work on Python 2.1 and beyond because it will
 910 use weak references.)</p>
 911 <p class="last">This first phase of the OOR plan is fairly significant and has
 912 required a lot of changes all over wxPython, most of which should
 913 be transparent to you, however I'm not 100% sure that it didn't
 914 introduce any new bugs that are hiding somewhere and didn't get
 915 stomped on during my testing.  So please be sure to test everything
 916 thoroughly when you install this version and be sure to report any
 917 object-type related oddities to me.</p>
 918 </dd>
 919 </dl>
 920 <p>There is now a wxObject class that most other classes derive from like
 921 in C++, but the methods provided don't really match but are wxPython
 922 specific.  It could have been added long ago but OOR required it so it
 923 finally got done.</p>
 924 <p>Finally added wxPyLineShape.GetLineControlPoints, which has been on my
 925 list for a while.  The above OOR modification made this easier.</p>
 926 <p>Fixed the __cmp__ methods for wxPoint and others.</p>
 927 <p>Added wxWave.</p>
 928 <p>Added the wxPython.lib.mixins package to the library, it is where
 929 useful mix-in classes can be placed.  Currently there is one to help
 930 make the columns in a wxListCtrl sortable, and the MagicIMageList from
 931 Mike Fletcher.  If you have any custom code that can be factored out
 932 of existing classes into a mix-in that would be useful to others
 933 please send it to me for inclusion in this package.</p>
 934 <p>Added a few little sample applications to help newbies to get started
 935 by having smaller functional apps to play with.  They can be found in
 936 wxPython/samples.</p>
 937 </div>
 938 <div class="section" id="id19">
 939 <h1><a name="id19">2.2.6</a></h1>
 940 <p>No changes happened in the Python wrappers for this release, only
 941 changes and fixes in the wxWindows library.</p>
 942 </div>
 943 <div class="section" id="id20">
 944 <h1><a name="id20">2.2.5</a></h1>
 945 <p>New typemaps for wxString when compiling for Python 2.0 and beyond
 946 that allow Unicode objects to be passed as well as String objects.  If
 947 a Unicode object is passed PyString_AsStringAndSize is used to convert
 948 it to a wxString using the default encoding.</p>
 949 <p>Fixed the generic buttons so tool tips work for them.</p>
 950 <p>Fixed a bug in the demo's tree control.</p>
 951 <p>Added a listbox to the listbox demo that shows how to find items with
 952 a matching prefix as keys are typed.</p>
 953 <p>Added code to the wxListCtrl demo to show how to get text from a
 954 column in report mode.</p>
 955 <p>Added code to the toolbar demo to clear the long help from the status
 956 bar after 2 seconds.</p>
 957 <p>Added wxJoystick.</p>
 958 <p>Fixed wxTimer so it can be used as described in the docs, either with
 959 a Notify method in a subclass, or sending an event to a wxEvtHandler
 960 object, (usually a window.)</p>
 961 <p>Added wxNotifyEvent.Allow()</p>
 962 <p>Fixed GOBS of reference leaks.</p>
 963 <p>Massive code changes and cleanup to allow wxPython to be split into
 964 multiple extension modules again.  A Python CObject is used to allow
 965 the &quot;export&quot; of SWIG functions and other common helper functions from
 966 the wxc module to other modules, even if they are in separate shared
 967 libraries.  Should also be usable from 3rd party code, just include
 968 wxPython/src/export.h</p>
 969 <p>Changed the default setup so the following are built as separate
 970 extension modules:  calendar, glcanvas, grid, html, ogl, stc, and
 971 utils.  Will probably add more later.</p>
 972 <p>Changed the wxPrinterDC to use the new constructor taking a
 973 wxPrintData object.  The old ctor is still there using the
 974 wxPrinterDC2 name.</p>
 975 <p>Added wxPython.lib.anchors.py from Riaan Booysen.  It contains a class
 976 that implements Delphi's Anchors with wxLayoutConstraints.</p>
 977 <p>Added wxPython.lib.fancytext from Timothy Hochberg.</p>
 978 <p>Changed the GenericButtons to send their event in idle time, so the
 979 mouse won't be captured when the event handler is called.</p>
 980 <p>Added wxPython.lib.rpcMixin from Greg Landrum, although it's not
 981 integrated with the demo yet.  It allows a wxPython GUI to be an
 982 XML-RPC server.</p>
 983 </div>
 984 <div class="section" id="new-in-2-2-2">
 985 <h1><a name="new-in-2-2-2">New in 2.2.2</a></h1>
 986 <p>Significantly changed how the wxStyledtextCtrl code that wraps
 987 Scintilla is implemented.  Most of it is now automatically generated
 988 from an interface definition file provided by Scintilla.  This means
 989 that it will be much easier to stay in sync with new Scintilla
 990 releases, but also means that some of the method and identifier names
 991 have changed.  See wxPython/demo/data/stc.h for a copy of the C++
 992 interface from which the Python interface is generated.  There is now
 993 some inline documentation in that file that should really help explain
 994 how things work.</p>
 995 <p>I am now using the Python Distutils to build wxPython and to make some
 996 of the distribution files.  (See <a class="reference" href="http://www.python.org/sigs/distutils-sig/">http://www.python.org/sigs/distutils-sig/</a>)
 997 This means no more messing with my kludgy build.py/Makefile hack,
 998 builds will be more consistent with other Python extensions that also
 999 use Distutils, and will hopefully make wxPython easier to build for
1000 platforms where there have been troubles before.  If you are building
1001 wxPython for Python 1.5.2 or for 1.6, then you will need to get and
1002 install version 1.0 of Distutils from the website above.  If you are
1003 using Python 2.0 then you already have it.</p>
1004 <p>Added wxInputStream and the wxFileSystem family of classes,
1005 contributed by Joerg Baumann.</p>
1006 <p>Added wxProcess and support for it to wxExecute.  wxProcess lets you
1007 get notified when an asyncronous child process terminates, and also to
1008 get input/output streams for the child process's stdout, stderr and
1009 stdin.</p>
1010 <p>Removed the old python sizers.</p>
1011 <p>Added __add__, __sub__ and __cmp__ (equality check only) for wxPoint
1012 and wxRealPoint.</p>
1013 <p>Changed the build to make one big extension module instead of one for
1014 the core and each contrib.  This allowed me to do away with the
1015 libwxPyHelpers.so on unix systems.</p>
1016 <p>Lots of little fixes here and there.</p>
1017 <p>Some hacks on wxGTK to try and make the AutoComplete listbox in the
1018 wxStyledTextCtrl to behave better.  It's still not as nice as on
1019 wxMSW, but at least it's a bit more usable now.</p>

1036 depressed state.</p>
1037 <p>Added wxTipProvider and friends.  See the demo for an example.</p>
1038 <p>wxGrid can now change the cell highlight colour.</p>

1042 <p>Added wxCalendarCtrl.</p>
1043 <p>WARNING: A while back I asked what should be done about the Magic
1044 Method Names.  (Methods that are automatically turned into event
1045 handlers by virtue of their name.)  The consensus was that it is more
1046 confusing to have them than to try and expand them to have greater
1047 coverage.  I am finally getting around to removing the code that
1048 generates the event binding.  This means that if you are using any of
1049 the following method names without a EVT_* call that you need to
1050 modify your code to add the EVT_* to hook the event to the method.</p>
1051 <blockquote>
1052 OnChar
1053 OnSize
1054 OnEraseBackground
1055 OnSysColourChanged
1056 OnInitDialog
1057 OnPaint
1058 OnIdle
1059 OnActivate
1060 OnMenuHighlight
1061 OnCloseWindow
1062 OnScroll</blockquote>
1063 <p>Added wxSpinCtrl.</p>

1065 <div class="section" id="new-in-2-1-15">
1066 <h1><a name="new-in-2-1-15">New in 2.1.15</a></h1>
1067 <p>Fixed wxTreeCtrl.HitTest to return both the tree item as well as the
1068 flags that clairify where the click was in relation to the item.</p>
1069 <p>Fixed thread state problem in wxTreeCtrl.GetBoundingBox and
1070 GetSelections.</p>
1071 <p>Fixed some problems in OGL.  Also wxShape.SetClientData and
1072 .GetClientData can now deal with Python objects.</p>
1073 <p>Added wxListCtrl.SortItems and changed the demo to show how to use it.</p>
1074 <p>Plugged a memory leak.</p>
1075 <p>Wrapped the new wxGrid and friends.  The old wxGrid class is no longer
1076 available.  There are some incompatibilities, and unfortunately the
1077 new classes are not documented yet, (however the methods are more
1078 consistent with each other now so you may be able to guess pretty
1079 good...)</p>
1080 <p>Updated filebrowsebutton.py and calendar.py with changes from their
1081 authors.  There is now a FileBrowseButtonWithHistory class (what a
1082 mouthful!) and wxCalendar has printing support.</p>
1083 <p>Added ActiveXWrapper to the library, and some good demos of it too.
1084 It works great for embedding a COM (a.k.a OCX, a.k.a ActiveX) control
1085 in a window and calling its methods.  It actually creates a new class
1086 on the fly that derives from wxWindow, the COM CoClass and others
1087 needed to make it all work.  The resulting class can be instantiated
1088 just like wxWindow, used in sizers, etc.  It also responds to all COM
1089 method calls, properties, etc., and if the class or a mix-in has
1090 matching method names, then the COM events will be propogated back to
1091 them.</p>
1092 <p>Created a typemap that allows a string to be used for parameters
1093 expecting a wxColour type.  The string is either a colour name as
1094 defined in the wxColourDatabase, or a colour spec of the form
1095 &quot;#RRGGBB&quot;.  See the wxStyledTextCtrl demo for an example.</p>
1096 <p>I almost forgot to mention the wxStyledTextCtrl!  Yes, the
1097 wxStyledTextCtrl is finally in wxPython!!  (And the crowd goes
1098 wild...)   There's no documentaTion yet (the crowd boos and hisses...)
1099 but I've included a very readable source file in the
1100 wxPython/demo/data directory, a couple fairly good examples, and you
1101 can also refer to the Scintilla documentaion at
1102 <a class="reference" href="http://www.scintilla.org/ScintillaDoc.html">http://www.scintilla.org/ScintillaDoc.html</a> to help fill in the gaps
1103 until the docs are done.  (The croud murmers contentedly as the tool
1104 provider smiles convincingly and removes his flame-proof suit.)</p>

1106 <div class="section" id="what-s-new-in-2-1-13">
1107 <h1><a name="what-s-new-in-2-1-13">What's new in 2.1.13</a></h1>
1108 <p>Skipped a version number to match what has been released for wxGTK.</p>
1109 <p>Updated wxMVCTree and added a demo for it, also fixed layout on GTK
1110 and some flicker problems.</p>
1111 <p>Added a wrapper class for the Visualization ToolKit (or VTK) in the
1112 wxPython.lib.vtk module.  (<a class="reference" href="http://www.kitware.com/">http://www.kitware.com/</a>)</p>
1113 <p>Fixed wxTreeCtrl.SetItemImage and GetItemImage to recognise the new
1114 &quot;which&quot; parameter.</p>
1115 <p>Added wxPython.lib.spashscreen from Mike Fletcher.</p>
1116 <p>Added wxPython.lib.filebrowsebutton also from Mike Fletcher.</p>
1117 <p>Renamed wxTreeCtrl.GetParent to GetItemParent to avoid a name clash
1118 with wxWindow.GetParent.</p>
1119 <p>Added wxIntersectRect to compute the intersection of two wxRect's.
1120 It is used like this:</p>
1121 <blockquote>
1122 intersect = wxIntersectRect(rect1, rect2)</blockquote>
1123 <p>If r1 and r2 don't intersect then None is returned, otherwise the
1124 rectangle representing the intersection is returned.</p>
1125 <p>Some bug fixes for Clipboard and Drag-n-Drop.</p>
1126 <p>Rotated text!!!  WooHoo!  (See wxDC.DrawRotatedText())</p>
1127 <p>Added a set of Generic Buttons to the library.  These are simple
1128 window classes that look and act like native buttons, but you can have
1129 a bit more control over them.  The bezel width can be set in addition
1130 to colours, fonts, etc.  There is a ToggleButton as well as Bitmap
1131 versions too.  They should also serve as a good example of how to
1132 create your own classes derived from wxControl.</p>
1133 <p>The C++ wxToolBar classes have been redone, and so have the wxPython
1134 wrappers.  There have been slight modifications to some of the methods
1135 but shouldn't impact anybody too much.  I took the opportunity to add
1136 support for setting user data on each toolbar tool.  The new AddTool
1137 methods look like this:</p>
1138 <blockquote>
1139 <dl>
1140 <dt>def AddTool(ID,</dt>
1141 <dd>bitmap,
1142 pushedBitmap = wxNullBitmap,
1143 toggle = FALSE,
1144 clientData = NULL,
1145 shortHelpString = &quot;&quot;,
1146 longHelpString = &quot;&quot;)</dd>
1147 <dt>def AddSimpleTool(ID,</dt>
1148 <dd>bitmap,
1149 shortHelpString = &quot;&quot;,
1150 longHelpString = &quot;&quot;,
1151 toggle=FALSE)</dd>
1152 </dl>
1153 </blockquote>
1154 <p>There are also corresponding InsertTool and InsertSimpleTool methods
1155 that additionally take an integer position as the first parameter.</p>
1156 <p>Added a wrapper for the new PCX and TIFF ImageHandlers.</p>
1157 <p>wxRect now simulates attributes named left, right, top and bottom.</p>
1158 <p>Removed all non wx stuff from the glcanvas module since DA's PyOpenGL
1159 is better and compatible with the wxGLCanvas.  You can get it at
1160 <a class="reference" href="http://starship.python.net:9673/crew/da/Code/PyOpenGL">http://starship.python.net:9673/crew/da/Code/PyOpenGL</a>.</p>
1161 <p>Added some missing EVT functions.</p>
1162 <p>Added Dirk Holtwic's editor classes to the wxPython.lib.editor
1163 package.</p>
1164 <p>Changed all the &quot;LIST&quot; parameter names to &quot;choices&quot; to match the docs.</p>
1165 <p>More fixes for the wxFloatBar, and it now works on wxGTK even better
1166 than wxMSW!  (The feat is accomplished by using the wxTB_DOCKABLE
1167 style flag instead of trying to float it ourselves.)</p>
1168 </div>
1169 <div class="section" id="what-s-new-in-2-1-11">
1170 <h1><a name="what-s-new-in-2-1-11">What's new in 2.1.11</a></h1>
1171 <p>Skipped a few version numbers so wxMSW, wxGTK and wxPython are all
1172 syncronized.</p>
1173 <p>wxImage.SetData now makes a copy of the image data before giving it to
1174 wxImage.  I mistakenly thought that wxImage would copy the data
1175 itself.</p>
1176 <p>Fixed wxMSW's notebook so the pages get their size set as they are
1177 being added.  This should remove the need for our
1178 wxNotebook.ResizeChildren hack.</p>
1179 <p>wxPanels now support AutoLayout, and wxNotebooks and wxSplitterWindows
1180 no longer tell their children to Layout() themselves.  This will
1181 probably only effect you if you have a wxWindow with AutoLayout inside
1182 a notebook or splitter.  If so, either change it to a wxPanel or add
1183 an EVT_SIZE handler that calls Layout().</p>
1184 <p>Fixed deadlock problem that happened when using threads.</p>
1185 <p>Added new HTML printing classes.</p>
1186 <p>Added wxWindow.GetHandle</p>
1187 <p>Apparently wxMouseEvent.Position has been deprecated in wxWindows as
1188 it is no longer available by default.  You can use GetPositionTuple
1189 (returning a tuple with x,y) instead, or GetPosition (returning a
1190 wxPoint.)</p>
1191 <p>Added wxPostEvent function that allows events to be posted and then
1192 processed later.  This is a thread-safe way to interact with the GUI
1193 thread from other threads.</p>
1194 <p>Added Clipboard and Drag-and-Drop classes.</p>
1195 <p>Added wxFontEnumerator.</p>
1196 <p>Many updates to wxMenu, wxMenuBar.</p>
1197 <p>wxPyEvent and wxPyCommandEvent derived classes now give you the actual
1198 Python object in the event handler instead of a new shadow.</p>
1199 <p>Added a Calendar widget from Lorne White to the library.</p>
1200 <p>Made some fixes to the wxFloatbar.  It still has some troubles on
1201 wxGTK...</p>
1202 <p>Added an MVC tree control from Bryn Keller to the library.</p>

1205 <h1><a name="what-s-new-in-2-1-5">What's new in 2.1.5</a></h1>
1206 <p>This is a quick bug-fix release to take care of a few nasties that
1207 crept in at the last minute before 2.1.4 was called done.  No new
1208 major features.</p>

1212 <p>This release is NOT syncronized with a snapshot release of wxGTK or
1213 wxMSW.  For MSW this isn't much of a problem since you can get the
1214 binaries from the web site.  For other platforms you'll have to build
1215 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>)
1216 To get the same set of sources from CVS that I used, checkout using
1217 the wxPy-2-1-4 tag.</p>
1218 <p>Now back to what's new...</p>
1219 <p>Much more support for event-less callbacks and add-on modules.</p>
1220 <p>Created add-on module with wxOGL classes.</p>
1221 <p>Added wxWindow.GetChildren().  Be careful of this.  It returns a <em>copy</em>
1222 of the list of the window's children.  While you are using the list if
1223 anything changes in the real list (a child is deleted, etc.) then the
1224 list you are holding will suddenly have window references to garbage
1225 memory and your app will likely crash.  But if you are careful it works
1226 great!</p>
1227 <p>Added a bunch of new and missing methods to wxTreeCrtl.  The
1228 SortChildren method is now supported, but currently only for the
1229 default sort order.</p>
1230 <p>Added typemaps for wxSize, wxPoint, wxRealPoint, and wxRect that allow
1231 either the actual objects or Python sequence values to be used.  For
1232 example, the following are equivallent:</p>
1233 <blockquote>
1234 win = wxWindow(parent, size = wxSize(100, 100))
1235 win = wxWindow(parent, size = (100, 100))</blockquote>
1236 <p>Super-charged the wxHtml module.  You can now create your own tag
1237 handlers and also have access to the parser and cell classes.  There
1238 is a tag handler in the library at wxPython.lib.wxpTag that
1239 understands the WXP tag and is able to place wxPython windows on HTML
1240 pages.  See the demo for an example.</p>
1241 <p>A bunch of the methods of wxMenuBar were previously ifdef'd out for
1242 wxGTK.  Added them back in since the methods exist now.</p>
1243 <p>Wrapped the wxHtmlHelpController and related classes.</p>
1244 <p>Wrapped the C++ versions of wxSizer and friends.  The Python-only
1245 versions are still in the library, but deprecated.  (You will get a
1246 warning message if you try to use them, but the warning can be
1247 disabled.) The usage of the C++ versions is slightly different, and
1248 the functionality of wxBorderSizer is now part of wxBoxSizer.  I have
1249 added a few methods to wxSizer to try and make the transition as
1250 smooth as possible, I combined all Add methods into a single method
1251 that handles all cases, added an AddMany method, etc.  One step I did
1252 not take was to make the default value of flag in the Add method be
1253 wxGROW.  This would have made it more backward compatible, but less
1254 portable to and from wxWin C++ code.  Please see the docs and demo for
1255 further details.</p>
1256 <p>Added wxPyEvent and wxPyCommandEvent classes, derived from wxEvent and
1257 wxCommandEvent.  Each of them has SetPyData and GetPyData methods that
1258 accept or return a single Python object.  You can use these classes
1259 directly or derive from them to create your own types of event objects
1260 that can pass through the wxWindows event system without loosing their
1261 Python parts (as long as they are stored with SetPyData.)  Stay tuned
1262 for more info and examples in future releases.</p>
1263 <p>Added wxPython.lib.grids as an example of how to derive a new sizer
1264 from the C++ sizers.  In this module you will find wxGridSizer and
1265 wxFlexGridSizer.  wxGridSizer arrainges its items in a grid in which
1266 all the widths and heights are the same.  wxFlexgridSizer allows
1267 different widths and heights, and you can also specify rows and/or
1268 columns that are growable.  See the demo for a couple examples for how
1269 to use them.</p>
1270 <p>Added the wxValidator class, and created a class named wxPyValidator
1271 that should be used for the base class of any Python validators.  See
1272 the demo for an example.  Please note that you MUST implement a Clone
1273 method in your validator classes because of the way some things work
1274 in the underlying C++ library.  I did not add wxTextValidator because
1275 of some issues of how it transfers data to and from a wxString, which
1276 in wxPython is automatically translated to and from Python strings, so
1277 there would never be a concrete wxString that would hang around long
1278 enough for the validator to do its job.  On the other hand, it should
1279 be real easy to duplicate the functionality of wxTextValidator in a
1280 pure Python class derived from wxPyValidator.</p>
1281 <p>I've finally added a feature that has been on my list for close to two
1282 years!  Ever wondered what that zero is for when you create your app
1283 object?  Well now you can leave it out or explicitly set it to a true
1284 value.  This value now controls what is to be done with sys.stdout and
1285 sys.stderr.  A false value leaves them alone, and a true value sets
1286 them to an instance of wxPyOnDemandOutputWindow.  (On windows the
1287 default is true, on unix platforms the default is false.)  This class
1288 creates a frame containing a wxTextCtrl as soon as anything is written
1289 to sys.stdout or sys.stderr.  If you close the window it will come
1290 back again the next time something is written.  (You can call
1291 app.RestoreStdio to turn this off.)  If you would rather that the stdio be
1292 redirected to a file, you can provide a second parameter to your app
1293 object's constructor that is a filename.  If you want to use your own
1294 class instead of wxPyOnDemandOutputWindow you can either implement
1295 RedirectStdio() in you app class or change the value of
1296 wxApp.outputWindowClass like this:</p>
1297 <blockquote>
1298 <dl>
1299 <dt>class MyApp(wxApp):</dt>
1300 <dd><p class="first">outputWindowClass = MyClass</p>
1301 <dl class="last">
1302 <dt>def OnInit(self):</dt>
1303 <dd>frame = MyFrame()
1304 self.SetTopWindow(frame)
1305 return true</dd>
1306 </dl>
1307 </dd>
1308 </dl>
1309 </blockquote>
1310 <p>Please see the implementation of wxPyOnDemandOutputWindow and wxApp in
1311 wx.py for more details.  A few words of caution:  if you are running
1312 your app in a debugger, changing sys.stdout and sys.stderr is likely
1313 to really screw things up.</p>
1314 <p>Added wxCaret.  Unfortunately it's author has still not documented it
1315 in the wxWindows docs...</p>
1316 <p>Some new 3rd party contributions in wxPython.lib.  PyShell, in
1317 shell.py is an interesting implementaion of an interactive Python
1318 shell in wxWindows.  floatbar.py has a class derived from wxToolBar
1319 that can sense mouse drags and then reparent itself into another
1320 frame. Moving the new frame close to where it came from puts the tool
1321 bar back into the original parent.  (Unfortunately there is currently
1322 a bug in wxGTK's wxFrame.SetToolBar so the FloatBar has some
1323 problems...)</p>

1327 <p>This release is syncronized with release 2.1 snapshot 9 of wxWindows.</p>
1328 <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>)
1329 for some of the new features and such.  Also they have encorporated my
1330 patches so there is really no reason to stick with the current (very
1331 old) release...  This version of SWIG gives the following new
1332 features:</p>
1333 <blockquote>
1334 <ol class="arabic">
1335 <li><p class="first">Keyword arguments.  You no longer have to specify all the
1336 parameters with defaults to a method just to specify a
1337 non-default value on the end.  You can now do this instead:</p>
1338 <blockquote>
1339 <p>win = wxWindow(parent, -1, style = mystyle)</p>
1340 </blockquote>
1341 </li>
1342 <li><p class="first">There is now an an equivalence between Python's None and C++'s
1343 NULL.  This means that any methods that might return NULL will
1344 now return None and you can use none where wxWindows might be
1345 expecting NULL.  This makes things much more snake-ish.</p>
1346 </li>
1347 </ol>
1348 </blockquote>
1349 <p>There is a new build system based on a new Python program instead of
1350 raw makefiles.  Now wxPython builds are virtually the same on MSW or
1351 Unix systems.  See the end of this file for new build instructions and
1352 see distrib/build.py for more details.</p>
1353 <p>wxDC.Bilt now includes the useMask parameter, and has been split into
1354 two different versions.  wxDC.BlitXY is like what was there before and
1355 takes raw coordinants and sizes, and the new wxDC.Blit is for the new
1356 interface using wxPoints and a wxSize.</p>

1359 <h1><a name="what-s-new-in-2-1b2">What's new in 2.1b2</a></h1>
1360 <p>Added the missing wxWindow.GetUpdateRegion() method.</p>
1361 <p>Made a new change in SWIG (update your patches everybody) that
1362 provides a fix for global shadow objects that get an exception in
1363 their __del__ when their extension module has already been deleted.
1364 It was only a 1 line change in .../SWIG/Modules/pycpp.cxx at about
1365 line 496 if you want to do it by hand.</p>
1366 <p>It is now possible to run through MainLoop more than once in any one
1367 process.  The cleanup that used to happen as MainLoop completed (and
1368 prevented it from running again) has been delayed until the wxc module
1369 is being unloaded by Python.</p>
1370 <p>I fixed a bunch of stuff in the C++ version of wxGrid so it wouldn't
1371 make wxPython look bad.</p>
1372 <p>wxWindow.PopupMenu() now takes a wxPoint instead of  x,y.  Added
1373 wxWindow.PopupMenuXY to be consistent with some other methods.</p>
1374 <p>Added wxGrid.SetEditInPlace and wxGrid.GetEditInPlace.</p>
1375 <p>You can now provide your own app.MainLoop method.  See
1376 wxPython/demo/demoMainLoop.py for an example and some explaination.</p>
1377 <p>Got the in-place-edit for the wxTreeCtrl fixed and added some demo
1378 code to show how to use it.</p>
1379 <p>Put the wxIcon constructor back in for GTK as it now has one that
1380 matches MSW's.</p>
1381 <p>Added wxGrid.GetCells</p>
1382 <p>Added wxSystemSettings static methods as functions with names like
1383 wxSystemSettings_GetSystemColour.</p>
1384 <p>Removed wxPyMenu since using menu callbacks have been deprecated in
1385 wxWindows.  Use wxMenu and events instead.</p>
1386 <dl>
1387 <dt>Added alternate wxBitmap constructor (for MSW only) as</dt>
1388 <dd>wxBitmapFromData(data, type, width, height, depth = 1)</dd>
1389 </dl>
1390 <p>Added a helper function named wxPyTypeCast that can convert shadow
1391 objects of one type into shadow objects of another type.  (Like doing
1392 a down-cast.)  See the implementation in wx.py for some docs.</p>
1393 <p>Fixed wxImage GetData and SetData to properly use String objects for
1394 data transfer.</p>
1395 <p>Added access methods to wxGridEvent.</p>
1396 <p>New Makefile/Setup files supporting multiple dynamic extension modules
1397 for unix systems.</p>
1398 <p>Fixes for the wxGLCanvas demo to work around a strange bug in gtk.</p>
1399 <p>SWIG support routines now compiled separately instead of being bundled
1400 in wx.cpp.</p>

1404 <p>Fixed wxComboBox.SetSelection so that it actually sets the selected
1405 item.  (Actually just removed it from wxPython and let it default to
1406 wxChoice.SetSelection which was already doing the right thing.)</p>
1407 <p>Added the Printing Framework.</p>
1408 <p>Switched back to using the wxWindows DLL for the pre-built Win32
1409 version.  The problem was needing to reinitialize static class info
1410 data after loading each extension module.</p>
1411 <p>Lots of little tweaks and additions to reflect changes to various
1412 wxWindows classes.</p>
1413 <p>Fixed a bug with attaching objects to tree items.  Actually was a
1414 symptom of a larger problem with not obtaining the interpreter lock
1415 when doing any Py_DECREFs.</p>
1416 <p>wxSizer and friends.  Sizers are layout tools that manage a colection
1417 of windows and sizers.  Different types of sizers apply different
1418 types of layout algorithms.  You saw it here first!  These classes are
1419 not even in the wxWindows C++ library yet!</p>

1424 <p>Bug fix for occassional GPF on Win32 systems upon termination of a
1425 wxPython application.</p>
1426 <p>Added wxListBox.GetSelections returning selections as a Tuple.</p>
1427 <p>Added a wxTreeItemData that is able to hold any Python object and be
1428 associated with items in a wxTreeCtrl.  Added test pytree.py to show
1429 this feature off.</p>
1430 <p>Added wxSafeYield function.</p>
1431 <p>OpenGL Canvas can be optionally compiled in to wxPython.</p>
1432 <p>Awesome new Demo Framework for showing off wxPython and for learning
1433 how it all works.</p>
1434 <p>The pre-built Win32 version is no longer distributing the wxWindows
1435 DLL.  It is statically linked with the wxWindows library instead.</p>
1436 <p>Added a couple missing items from the docs.</p>
1437 <p>Added wxImage, wxImageHandler, wxPNGHandler, wxJPEGHandler,
1438 wxGIFHandler and wxBMPHandler.</p>

1461 <p>Well obviously the numbering scheme has changed.  I did this to
1462 reflect the fact that this truly is the second major revision of
1463 wxPython, (well the third actually if you count the one I did for
1464 wxWindows 1.68 and then threw away...) and also that it is associated
1465 with the 2.0 version of wxWindows.</p>
1466 <p>I have finally started documenting wxPython.  There are several pages
1467 in the wxWindows documentation tree specifically about wxPython, and I
1468 have added notes within the class references about where and how wxPython
1469 diverges from wxWindows.</p>
1470 <p>Added wxWindow_FromHWND(hWnd) for wxMSW to construct a wxWindow from a
1471 window handle.  If you can get the window handle into the python code,
1472 it should just work...  More news on this later.</p>

1500 <p>wxPython on wxGTK works!!!  Both dynamic and static on Linux and

1502 &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
1503 down a nasty DECREF bug.  Okay so I have to confess that it was just a
1504 DSM (Dumb Stupid Mistake) on my part but it was nasty none the less
1505 because the behavior was so different on different platforms.</p>
1506 <p>The dynamicly loaded module on Solaris is still segfaulting, so it

1511 <p>1. Worked on wxGTK compatibility.  It is partially working.  On a
1512 Solaris/Sparc box wxPython is working but only when it is statically
1513 linked with the Python interpreter.  When built as a dyamically loaded
1514 extension module, things start acting weirdly and it soon seg-faults.
1515 And on Linux both the statically linked and the dynamically linked
1516 version segfault shortly after starting up.</p>
