  14 <h1><a name="id1">2.5.4.1</a></h1>
  15 <p>wx.Sizer Add, Insert, and Prepend functions now return a reference to the
  16 wx.SizerItem that was added to the sizer, and the wx.SizerItem has a
  17 GetRect accessor to give the position of the item on the parent window.</p>
  18 <p>Added wx.Sizer.GetItem method which returns the wx.SizerItem for the given
  19 wx.Window, wx.Sizer or position index.</p>
  20 <p>wxMSW: wx.RadioButtons in the same group no longer have to be
  21 consecutive (there may be intervening controls). Without this fix, an
  22 out-of-sync assert is generated when clicking on a radio button and
  23 then calling GetValue().</p>
  24 <dl>
  25 <dt>Some XRC changes: </dt>
  26 <dd><ul class="first last simple">
  27 <li>Added 'icon' property to wxFrame and wxDialog</li>
  28 <li>No longer ignores menu bitmaps on non-MSW platforms</li>
  29 <li>Notebook page bitmaps are now supported</li>
  30 <li>added system colours and fonts support (based on patch #1038207)</li>
  31 </ul>
  32 </dd>
  33 </dl>
  34 <p>wxMSW: fix for [ 1052989 ] TextCtrl.SetBackgroundColour(wx.NullColour)
  35 bug.</p>
  36 <p>Added wx.PasswordEntryDialog analagous to wx.TextEntryDialog, allows
  37 detecting entering an empty string vs. cancel unlike the
  38 wx.GetPasswordFromUser dialog function.</p>
  39 <p>OGL patch from Shane Holloway:</p>
  40 <blockquote>
  41 <p>Two simple problems found in the new python ogl code.  First is
  42 the patch for _canvas.py.  Essentially:</p>
  43 <pre class="literal-block">
  44 dx = abs(dc.LogicalToDeviceX(x - self._firstDragX))
  45 dy = abs(dc.LogicalToDeviceY(y - self._firstDragY))
  46 </pre>
  47 <p>was incorrect because (x,y) and (self._firstDragX,
  48 self._firstDragY) are both already in Logical coordinates.
  49 Therefore the difference between the two is also in logical
  50 coordinates, and the conversion call is an error.  This bug
  51 surfaces when you have OGL on a scrollwin, and you are far from
  52 the origin of the canvas.</p>
  53 <p>The second change in _composit.py basically removes the assumption
  54 that the child is in both self._children and self._divisions.
  55 Causes many problems when it's not.  ;)</p>
  56 </blockquote>
  57 <p>Fixed GetSaveData and SetSaveData in wx.lib.multisash to not depend on
  58 the default way that class objectss are converted to strings.</p>
  59 <p>Fixed problem in StyledTextCtrl.Set[HV]ScrollBar that could leave the
  60 internal scrollbar visible.</p>
  61 <p>Added wx.StandardPaths which provides methods for determining standard
  62 system paths for each platform.</p>
  63 <p>wxMSW: The window background is now only erased by default if the
  64 background colour or background mode has been changed.  This better
  65 allows the default system themed behaviour to show through for
  66 uncustomized windows.  Explicit support added for using the correct
  67 theme texture for wx.Notebook pages and their children.</p>
  68 <p>wx.Image: Added support for alpha channels in interpolated and
  69 non-interpolated image rotation.  Added ConvertAlphaToMask helper
  70 method for turning shades of grey into shades of alpha and a colour.</p>
  71 <p>wxGTK2: Reimplemented DoDrawRotatedText() by way of a rotation of an
  72 alpha blended text bitmap.  It would be better if Pango could draw
  73 directly into an wxImage (as FreeType can,) but that is for later...</p>
  74 <p>Added wrappers and a demo for the wx.MediaCtrl class, which can play
  75 various forms of audio/video media using native codecs install on the
  76 system.  So far it is only implemented for Windows and OSX.</p>
  77 <p>wxGTK: Patch applied for Freeze()/Thaw() for wxTextCtrtl.</p>
  78 <p>Added &quot;gravity&quot; for splitter window (patch 1046105). Gravity is a
  79 floating-point factor between 0.0 and 1.0 which controls position of
  80 sash while resizing the wx.SplitterWindow.  The gravity specifies
  81 how much the left/top window will grow while resizing.</p>
  82 <p>wxMSW: wx.Slider's C++ implementation rewritten to be more
  83 maintainable and hopefully less buggy.  The position of the labels has
  84 also been changed in order to better comply with Microsoft's examples
  85 of how to use the control.</p>
  86 <p>wxMSW:  Fix wx.TreeCtrl to end label editing if the control loses
  87 focus (a slightly modified patch 1084592.)</p>
  88 <p>Added wx.EXEC_NODISABLE flag for wx.Execute, which will prevent all
  89 the app's windows being disabled while a synchronous child process is
  90 running.</p>
  91 <p>wxMSW: Much work to correct painting (or leaving transparent) of
  92 control backgrounds, properly using background themes on XP, etc.</p>
  93 <p>Fixed a circular reference problem with wx.Timer.  It will now
  94 completely cleanup after itself when the last reference to the timer
  95 is removed.  If you were previously using timer.Destroy() to cleanup
  96 your timers it will no longer work.  Instead you should hold a
  97 reference to the timer and then del the reference when you are
  98 finished with the timer.</p>
  99 <p>Updated to 1.3.24 of SWIG.  All of my big patches have been applied to
 100 the main SWIG source tree, but unfortunatly there were also some bugs
 101 added that affected the wxPython build and a few details in my
 102 original patch were changed/removed, so we are still not free of
 103 patches.  A new patch for SWIG is located in the wxPython/SWIG
 104 directory of the wxPython source tree.  SWIG 1.3.24 plus this patch
 105 should be used by anyone who is making custom modifications to
 106 wxPython's .i files, or building their own extension modules or
 107 etc. that need to interact with the wxPython swigged types.  For the
 108 morbidly curious, here are a few more details:</p>
 109 <blockquote>
 110 <ul class="simple">
 111 <li>Since it is now possible easily and simply share the SWIG type
 112 tables across modules I reverted to always using the stock SWIG
 113 runtime instead of my slightly hacked up version of it exported
 114 via the wxPython C API.</li>
 115 <li>The %name directive is now deprecated so I replaced most uses of
 116 it with a custom %Rename macro that uses %rename internally.
 117 These will evetually need to be replaced with a DocDecl macro
 118 when docstrings are added for those items.</li>
 119 <li>The &quot;this&quot; attribute of all SWIGged classes is no longer a
 120 string containing a &quot;swigified pointer&quot;, but rather a custom
 121 built-in type that holds the real C pointer to the object and
 122 the type info.  It can be converted to a string like the old
 123 value using str() or to the long integer value of the pointer
 124 using long().</li>
 125 </ul>
 126 </blockquote>
 127 <p>Added SetDefaultPyEncoding and GetDefaultPyEncoding functions which
 128 will set/get the encoding used by wxPython to convert string or
 129 unicode objects to/from wxString objects.  Previously the default
 130 Python encoding was always used, but unless the user had tweaked their
 131 sitecustomize.py file it is always &quot;ascii&quot;, which would result in
 132 errors if the strings contained character codes &gt;= 128.
 133 SetDefaultPyEncoding will now allow you to control which encoding will
 134 be used to do those conversions.  The default encoding is set to the
 135 value of <cite>locale.getdefaultlocale()[1]</cite> when wxPython is first
 136 imported.  Please see <a class="reference" href="http://www.alanwood.net/demos/charsetdiffs.html">http://www.alanwood.net/demos/charsetdiffs.html</a>
 137 for information on the differences between the common latin/roman
 138 encodings.</p>
 139 <p>Added wxStdDialogButtonSizer, which is a a special sizer that knows
 140 how to order and position standard buttons in order to conform to the
 141 current platform's standards.  You simply need to add each <cite>wx.Button</cite>
 142 to the sizer, and be sure to create the buttons using the standard
 143 ID's.  Then call <cite>Realize</cite> and the sizer will take care of the rest.</p>
 144 <p>wxMSW Toolbar: pass correct tool id (and not always -1) to the
 145 EVT_TOOL_RCLICKED handler</p>
 146 <p>wxGTK: Applied patch for combo box SELECTED events (no longer get
 147 lots of surplus events)</p>
 148 <p>wxGTK: Applied patch for proper menu highlight colour detection in
 149 wx.SystemSettings.</p>
 150 <p>wxGTK: Commited scrollbar patch #1093339 which sends lineup, linedown
 151 events based on intercepting the mouse down events.</p>
 152 <p>wxGTK: Applied patch #1102789 which solved conflicts between wxWidgets
 153 and GTK+'s context menu code.</p>
 154 <p>wxGTK: Applied patch #1100327 for correct feedback from DND actions
 155 (not all actions are allowed).</p>
 156 <p>Fixed memory leak in wxGrid::UpdateAttr[Rows][Or][Cols] (patch 1104355)</p>
 157 <p>For efficiency reasons, text controls no longer set the string for
 158 each text updated event, but rather query for the string value only
 159 when GetString is called from an event handler.</p>
 160 <p>Added wx.SL_INVERSE style which will cause wx.Slider to invert the min
 161 and max ends of the slider.</p>
 162 <p>Several patches applied, such as #1111174, #1110252 and others, that
 163 make the generic wx.TreeCtrl (used on wxGTK and wxMac) be more
 164 conistent with the wxMSW native wx.TreeCtrl.</p>
 165 <dl>
 166 <dt>XRCed:</dt>
 167 <dd><ul class="first last simple">
 168 <li>Edit-&gt;Locate command (Ctrl-L) for quick selection of items.
 169 Works with event-handling controls (buttons, text fields) but
 170 not with labels/sizers.</li>
 171 <li>Some improvements: relative paths for files supplied as command-
 172 line argument work correctly, notebook panels are highlighted
 173 better.</li>
 174 </ul>
 175 </dd>
 176 </dl>
 177 <p>wxMac: Fixed a long-standing issue where wxSlider controls with a
 178 hardcoded size would misplace their labels behind the slider control.</p>
 179 <p>wx.HtmlListBox fixed so calling RefreshLine(s) will cause the data for
 180 that line to be refetched from the overridden methods in the derived
 181 class.</p>
 182 <p>The default DoGetBestSize now includes the difference (if any) between
 183 the client size and total size of the window, (such as the size of
 184 borders.)  Code that sets the client size using the best size, or that
 185 added extra space to sizers to compensate for this bug may need to be
 186 changed.</p>
 187 <p>Can suppress themed notebook pages with the wxNB_NOPAGETHEME style or
 188 setting system option msw.notebook.themed-background to 0.</p>
 189 <p>wxSyledTextCtrl updated to use Scintilla 1.62.</p>
 190 <p>Can now set the msw.window.no-clip-children system option to 1 to
 191 eliminate weird refresh behaviour (delays between a window being
 192 erased and repainted, giving a ghostly gradual-redraw effect). May be
 193 a temporary 'fix' until properly fixed before 2.6.</p>
 194 <p>wxMac:  Toolbar is now more native looking with borderless toolbar
 195 buttons.</p>
 196 <p>wxMac: Switched wx.Bitmap to use newer Quartz object types and APIs
 197 internally.  This results in faster display and better alpha support.</p>
 198 <p>Added wx.DatePickerCtrl.</p>
 199 <p>wx.html.HtmlWindow now supports background images.</p>
 200 <p>Added wx.lib.gestures module from Daniel Pozmanter which supports
 201 using Mouse Gestures in an application.</p>
 202 <p>wxGTK2: ENTER and LEAVE mouse events are now sent for multi-line text
 203 controls.</p>
 204 <p>wxMSW:  &quot;Alt&quot; key (VK_MENU) now results in WXK_ALT keyboard event, not
 205 WXK_MENU</p>
 206 <p>Added modules from Peter Yared and Morgan Hua that implement the wx
 207 Doc/View framework in pure Python code.  See wx.lib.docview for the
 208 base implementation and wx.lib.pydocview for Python-specific
 209 extensions.  There are also a couple sample applications located in
 210 samples/docview.</p>
 211 <p>Added GetBitmap, GetIcon to wx.ImageList.</p>
 212 <p>wxGTK wx.Button.SetLabel no longer invalidates/resets the font.</p>
 213 <p>wx.Sizer.AddWindow, AddSizer, AddSpacer and etc. have now been
 214 undeprecated at the request of Riaan Booysen, the Boa Constructor team
 215 lead.  Boa needs them to help keep track of what kind of item is being
 216 managed by the sizer.  They are now just simple compatibility aliases
 217 for Add, and etc.</p>
 218 <p>The old C++ version of the OGL lib is no longer built by default.  Use
 219 the Python version in the wx.lib.ogl package instead.</p>
 220 <p>The wx.iewin module is no longer built by default.  You can use the
 221 wx.lib.iewin version instead.</p>
 222 <p>Fixed wx.BufferedPaintDC for scrolled windows to work whether the
 223 buffer is covering only the client area or the full virtual area of
 224 the scrolled window.  By default it will assume that only the client
 225 area is covered.  This is different than the old behavior so to
 226 indicate that the entire virtual area is covered simply add a
 227 style=wx.BUFFER_VIRTUAL_AREA parameter.</p>
 228 <p>wx.gizmos.TreeListCtrl:  Add support for the EVT_TREE_ITEM_GETTOOLTIP
 229 event.</p>
 230 <p>Added Resize, SetRGBRect, Size, and GetOrFindMaskColour methods to
 231 wx.Image.</p>
 232 <p>Added wx.Rect.IsEmpty</p>
 233 <dl>
 234 <dt>wxGTK:</dt>
 235 <dd><ul class="first last simple">
 236 <li>Corrected wx.ListBox selection handling</li>
 237 <li>Corrected default button size handling for different themes</li>
 238 <li>Corrected splitter sash size and look for different themes</li>
 239 <li>Fixed keyboard input for dead-keys</li>
 240 </ul>
 241 </dd>
 242 </dl>
 243 </div>
 244 <div class="section" id="id2">
 245 <h1><a name="id2">2.5.3.1</a></h1>
 246 <p>wxMac focus and border refreshes corrected.</p>
 247 <p>Updated internal PNG library.</p>
 248 <p>wxMac fix for metal appearance on wx.ToolBar.</p>
 249 <p>wx.grid.Grid fix allowing DoGetBestSize to be called before CreateGrid
 250 (which means that a min size doesn't need to be specified.)</p>
 251 <p>wxMac fix for not sending a native click to a control if it is not
 252 enabled (does an enable itself)</p>
 253 <p>Added wx.lib.ogl.DrawnShape, and fixed various little bugs in the new
 254 OGL.</p>
 255 <p>Added support to XRC and XRCed for the 3-state checkbox flags and also
 256 for wx.ToggleButton.  Updated the generic window styles supported by
 257 XRCed.</p>
 258 <p>It is now possible to create &quot;stock&quot; buttons.  Basically this means
 259 that you only have to provide one of the stock IDs (and either an
 260 empty label or a label that matches the stock label) when creating the
 261 button and wxWidgets will choose the stock label to go with it
 262 automatically.  Additionally on the platforms that have a native
 263 concept of a stock button (currently only GTK2) then the native stock
 264 button will be used.  For example, the following will result in a
 265 button with &quot;Cancel&quot; as the label and if run on wxGTK2 then there will
 266 also be an image of a red X:</p>
 267 <pre class="literal-block">
 268 b = wx.Button(parent, wx.ID_CANCEL)
 269 </pre>
 270 <p>Added wx.lib.ticker.Ticker class from Chris Mellon.</p>
 271 <p>Fix some incorrect clipping regions in wxSTC on wxGTK.</p>
 272 <p>Added wrapper for wx.grid.Grid.GetOrCreateCellAttr.</p>
 273 <p>Removed my copy of distutils from the wxPython source tree.  Now that
 274 I am no longer doing builds on Python 2.1 the newest distutils is no
 275 longer needed.  (There is still one small bug in Python 2.2 distutils
 276 on win32, but it is easily worked around.) This sovles the problem of
 277 incorrect builds on some systems where the system installed distutils
 278 has been patched to behave slightly differently, for example SuSE on
 279 x86_64 or Chandler's build.</p>
 280 <p>Updated to SWIG 1.3.22 (plus my patch.)  See wxPython/SWIG/README.txt
 281 in the source tree if you need to use SWIG when building your own copy
 282 of wxPython, or other extension modules that need to integrate with
 283 the wxPython modules.</p>
 284 <p>Added wx.Frame.RequestUserAttention which, if the platform suports it,
 285 will do something (such as flash the task bar item) to suggest to the
 286 user that they should look at that window.</p>
 287 <p>&quot;Fixed&quot; wx.grid.Grid.SetDefaultEditor and SetDefaultRenderer by making
 288 them register the editor or renderer for the &quot;string&quot; data type.</p>
 289 <p>Added depth param to wx.Image.ConvertToBitmap.</p>
 290 <p>Extended the wx.calendar.CalendarCtrl class with methods that get/set
 291 a Python datetime or date object.  (These will only work with Python
 292 2.3+) The methods are PySetDate, PyGetDate, PySetLowerDateLimit,
 293 PySetUpperDateLimit, PySetDateRange, PyGetLowerDateLimit, and
 294 PyGetUpperDateLimit.  Also, CalendarEvent was extended with PySetDate
 295 and PyGetDate methods.</p>
 296 <p>wxMSW: SetBackgroundColour on a wx.Choice or a wx.ComboBox will now
 297 also set the colour of the dropdown.</p>
 298 <p>wxMac: MessageDialog now supports wx.NO_DEFAULT style</p>
 299 <p>wxMSW: added AssociateHandle and DissociateHandle to wx.Window</p>
 300 <p>wxMac: fix for toolbar tooltips</p>
 301 <p>wx.Sizer.Show (and Hide) now take an optional parameter specifying if
 302 the item to be shown should be searched for recursivly in subsizers,
 303 and return a boolean value indicating if the item was found.</p>
 304 <p>wxMSW: fixed MaximizeEvent generation in wx.Frame</p>
 305 <p>wxMSW: fixed sending duplicate EVT_COMBOBOX events</p>
 306 <p>Smoother time estimation updates in wx.ProgressDialog (patch 992813)</p>
 307 <p>Made wx.Listbook events more consistent with wx.Notebook ones (patch
 308 1001271)</p>
 309 <p>Fixed rounding errors in variable status bar panes widths computation
 310 (patch 1030021)</p>
 311 <p>Added possibility to specify printer bin (patch 910272)</p>
 312 <p>wxMSW: fixed wx.ListCtrl's SetWindowStyleFlag() to not remove
 313 WS_VISIBLE; also refresh the control automatically (closes bug
 314 1019440)</p>
 315 <p>Added wx.Choicebook, yet another notebook-like control.</p>
 316 <p>wxMSW: Make radiobutton tab behaviour the same on MSW as in standard
 317 MSW app, i.e. tab into the activated, not necessarily the first radio
 318 button.</p>
 319 <p>Added limited support for wxEventLoop (you can't derive from a
 320 wx.PyEventLoop version yet...)  Updated and moved the sample showing
 321 how to replace the MainLoop to samples/mainloop/mainloop.py.</p>
 322 <p>The C++ xrc lib has been moved out of contrib and into the core, so it
 323 is always built by default.  wxPython's build has also changed
 324 accordingly and will build the xrc module as part of the core set of
 325 modules built by default.  If you were axplicitly using BUILD_XRC then
 326 it will no longer be recognized as a build option, otherwise you
 327 should notice no difference.</p>
 328 <p>wxMac: Fixed radio toolbar buttons to correctly untoggle the others
 329 when a new one is selected.</p>
 330 <p>wxMac: Fixed GetLineLength and GetLineText for MLTE text controls</p>
 331 <p>wxMac: wx.TaskBarIcon is implemented by allowing you to change the
 332 app's icon on the Dock and also specifying a menu that should be
 333 merged with the normal dock popup menu.  See the MigrationGuide for
 334 more details and a warning.</p>
 335 <p>Added wx.TopLevelWindow.IsActive() which tells you if the frame or
 336 dialog is or containts the active window with the keyboard focus.</p>
 337 <p>Added ability to create a font based on pixel size rather than point
 338 size via the FontFromPixelSize constructor.</p>
 339 <p>Updated the Scintilla used by StyledTextCtrl to version 1.61</p>
 340 <p>Improved image HitTest for TreeListCtrl.</p>
 341 <p>Added wx.App.IsMainLoopRunning.</p>
 342 <p>wxGTK: Make wxComboBox spit out a bit fewer surplus events when
 343 holding down the mouse button.</p>
 344 <p>wxGTK: Enable key based navigation through notebook tabs as in the
 345 native control with Left and right keys. Support for vetoing.</p>

 407 <li>Some tweaks in the demo and samples to correct layout, some
 408 flicker problems, and namespace use.</li>
 409 <li>Add wx.Image.ConvertAlphaToMask</li>
 410 <li>Minor corrections in wx.lib.dialogs</li>
 411 <li>wx.FileHistory constructor now accepts the documented 2nd
 412 parameter.</li>
 413 <li>Corrections for exceptions in the new ogl</li>
 414 <li>Fixed XRCed to not use reparenting of windows to implement caching
 415 of property panels, since Reparent on wxMac is not implemented.</li>
 416 <li>Add support for wxTAB_TRAVERSAL to the XRC handler for
 417 wxScrolledWindow.</li>
 418 <li>Add support for all wxListBox styles to the XRC handler for
 419 wxCheckListBox.</li>
 420 <li>Fix for wx.Listbook.DeleteAllPages to really delete everything.</li>
 421 <li>wxGTK2 now supports alpha blended bitmap drawing</li>
 422 <li>Made wx.grid.Grid play nicer with sizers.</li>
 423 <li>etc.</li>

 428 <h1><a name="id4">2.5.2.7</a></h1>
 429 <p>wx.ADJUST_MINSIZE is now the default behaviour for window items in
 430 sizers.  This means that the item's GetMinSize and/or GetBestSize will
 431 be called when calculating layout and the return value from that will
 432 be used for the minimum size used by the sizer.  The wx.FIXED_MINSIZE
 433 flag was added that will cause the sizer to use the old behaviour in
 434 that it will <em>not</em> call the window's methods to determine the new best
 435 size, instead the minsize that the window had when added to the sizer
 436 (or the size the window was created with) will always be used.  Please
 437 see the Sizers section in the Migration Guide for more details.</p>
 438 <p>Added new MaskedEditControl code from Will Sadkin.  The modules are
 439 now locaed in their own sub-package, wx.lib.masked.  Demos updated.</p>
 440 <p>The changes that implemented the incompatible wx.DC methods in 2.5.1.5
 441 have been reverted.  The wx.DC methods are now compatible with the 2.4
 442 implemetation.  In addition a set of renamed methods have been added
 443 that take wx.Point and/or wx.Size objects instead of individual
 444 parameters.</p>
 445 <p>Added wx.lib.mixins.listctrl.TextEditMixin, a mixin class that allows
 446 all columns of a wx.ListCtrl in report mode to be edited.</p>
 447 <p>Deprecated the wx.iewin module.</p>
 448 <p>Deprecated the wx.Sizer.AddWindow, AddSizer, AddSpacer methods as well
 449 as their Insert* and Prepend* counterparts.</p>
 450 <p>Added a generic StaticBitmap class in wx.lib.statbmp for the same
 451 reasons that stattext was created, so it could be mouse sensitive on
 452 all platforms like normal windows.  Also updated stattext.py and
 453 buttons.py to handle attribute (font &amp; colour) defaults and
 454 inheritance the new way.  If you have custom controls of your own you
 455 should review stattxt.py or one of the others to see how it is to be
 456 done.</p>
 457 <p>wx.InitAllImageHandlers is now an empty function that does nothing but
 458 exist for backwards compatibility.  The C++ version is now called
 459 automatically when wxPython is initialized.  Since all the handlers
 460 are included in the wxWidgets shared library anyway, this imposes only
 461 a very small amount of overhead and removes several unneccessary
 462 problems.</p>
 463 <p>Replaced wx/lib/pubsub.py with a version that uses weak references to
 464 track the subscribers, plus other fixes/additions.  Thanks go to
 465 Oliver Schoenborn and Robb Shecter.</p>
 466 <p>wxGTK now uses gtk_init_check so wxPython can raise an exception if
 467 there is no DISPLAY available or other initializaion problem.</p>
 468 <p>wx.GetKeyState now has an implementation for wxGTK and is able to
 469 detect the up/down or toggle state of modifier and toggle keys.</p>
 470 <p>The LC_NUMERIC locale is now reset back to &quot;C&quot; (compatibility) when
 471 running on wxGTK to work around the fact that GTK requires the locale
 472 to be set to the system settings but Python depends on LC_NUMERIC
 473 remaining compatible with &quot;C&quot;.</p>
 474 <p>Switched gizmos.TreeListCtrl to the newer version of the code from the
 475 wxCode project.</p>
 476 <p>OGL is dead! LONG LIVE OGL!  (Oops, sorry.  A bit of my dramatic side
 477 leaked out there...)  The wx.ogl module has been deprecated in favor
 478 of the new Python port of the OGL library located at wx.lib.ogl
 479 contributed by Pierre Hjälm.  This will hopefully greatly extend the
 480 life of OGL within wxPython by making it more easily maintainable and
 481 less prone to getting rusty as there seems to be less and less
 482 interest in maintaining the C++ version.  At this point there are just
 483 a couple minor known compatibility differences, please see the
 484 <a class="reference" href="MigrationGuide.html">MigrationGuide</a> file for details.</p>
 485 <p>EVT_STC_POSCHANGED has been removed as it has been deprecated in
 486 Scintilla for several releases now.</p>
 487 <p>All the Window and GDI (pen, bitmap, etc.) class constructors and also
 488 many toplevel functions and static methods will now check that a
 489 wx.App object has already been created and will raise a
 490 wx.PyNoAppError exception if not.</p>
 491 <p>Added more default args as needed to allow most window types to be
 492 constructed with only the parent window arg.  In some cases other args
 493 may be required for normal operation, but they can usually be set
 494 after construction.</p>
 495 <p>Removed the deprecated ErrorDialogs and PythonBitmaps modules.  If you
 496 were using these in your apps then please join wxPython-dev and assist
 497 with a more modern reimplementation.</p>
 498 <p>Added a new version (0.8.3) of FloatCanvas from Chris Barker.  It's now
 499 in a subpackage of wx.lib.</p>
 500 <p>It is now possible to change the tab traversal order of controls on a
 501 panel or dialog.  For details see the new MoveAfterInTabOrder and
 502 MoveBeforeInTabOrder methods of wx.Window.</p>
 503 <p>Applied (and heavily modified) a patch from Eugene
 504 &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
 505 edited and reloaded, all from within the demo.  You can switch back
 506 and forth between the default and your edited version, and any errors
 507 ocurring upon the reload are reported on the Demo tab.</p>
 508 <p>Added a menu item in the demo that will open a PyShell window that has
 509 the app and demo frame preloaded in the namespace.  This is another
 510 good way to explore and play with the objects in the currently running
 511 sample.  For example, load the Button sample and then do the following
 512 in the PyShell:</p>
 513 <pre class="literal-block">
 514 &gt;&gt;&gt; b = frame.demoPage.GetChildren()[0]
 515 &gt;&gt;&gt; for x in range(0, 500, 10):
 516 ...     b.Move((x, 50))
 517 ...     app.Yield(True)
 518 ...     wx.MilliSleep(10)
 519 </pre>
 520 <p>wxGTK: Applied wxNO_BORDER patch (#1098374) for text control and combo
 521 box.</p>

 525 <p>(See also the <a class="reference" href="MigrationGuide.html">MigrationGuide</a> file for details about some of the
 526 big changes that have happened in this release and how you should
 527 adapt your code.)</p>
 528 <p>The wxWindows project and library is now known as wxWidgets.  Please
 529 see <a class="reference" href="http://www.wxwindows.org/name.htm">http://www.wxwindows.org/name.htm</a> for more details.  This won't
 530 really affect wxPython all that much, other than the fact that the
 531 wxwindows.org domain name will be changing to wxwidgets.org, so mail
 532 list, CVS, and etc. addresses will be changing.  We're going to try
 533 and smooth the transition as much as possible, but I wanted you all to
 534 be aware of this change if you run into any issues.</p>
 535 <p>Many, many little fixes, changes and additions done as part of the move
 536 to wxWidgets 2.5 that I have forgotten about.</p>
 537 <p>Added wxMirrorDC.</p>
 538 <p>Added wxIconLocation</p>
 539 <p>Added Python wrappers and demos for the new wxVScrolledWindow,
 540 wxVListBox, and wxHtmlListBox classes.</p>
 541 <p>Added wrappers for wxBookCtrl and wxListbook.  wxNotebook now derives
 542 from wxBookCtrl.</p>
 543 <p>Added Gordon Williams' PyPlot module to the library, available as the
 544 wx.lib.plot module.</p>
 545 <p>I made a small but important change in the code that aquires the
 546 Python Global Interpreter Lock to try and prevent deadlocks that can
 547 happen when there are nested attempts to aquire the GIL.</p>
 548 <p>The RPMs will now install menu items on Mandrake Linux in
 549 Applications/Development/Tools for PyCrust, XRCed, etc.  The RPMs are
 550 also installing icons and <tt class="literal"><span class="pre">*.desktop</span></tt> items in the generic KDE and
 551 GNOME locations, but I don't know yet if they are resulting in menu
 552 items on non-Mandrake systems.  (It didn't automatically do it on my
 553 RH-9 build box but I didn't chase it very far...)  If you have ideas
 554 for how to improve the .spec file to work better and/or on more
 555 distros please send me a patch.</p>
 556 <p>The RPMs are now built on a fairly generic RH-9 box, and I have tested
 557 installing them also on my main Mandrake 9.2 box.</p>
 558 <p>There are some big changes in the OS X disk image.  The actual
 559 Installer package now <em>only</em> installs the wxMac dynlibs, wxPython
 560 extension modules and Python packages, and also the command-line tool
 561 scripts. The remaining items (demo, samples, and application bundles
 562 for the Demo, PyCrust and XRCed) are now top-level items in the disk
 563 image (.dmg file) that users can just drag and drop to wherever they
 564 want to put them.</p>
 565 <p>The wxWave class has been renamed to wxSound, and now has a slightly
 566 different API.</p>
 567 <p>Updated the AnalogClockWindow with many enhancements from E. A. Tacão.</p>
 568 <p>wxMac now has wx.ToggleButton!</p>
 569 <p>wx.stc.StyledTextCtrl has been updated to version 1.58 of Scintilla.</p>
 570 <p>To help with the wx.stc.StyledTextCtrl performance issues on wxMac
 571 I've added a SetUseAntiAliasing method (and GetUseAntiAliasing too)
 572 that will turn off the use of antialiased fonts in the wxSTC, allowing
 573 it to bypass the slow text measuring routines and use the fast and
 574 simple one instead.  By default the setting is turned off (on wxMac
 575 only.)  When run on OSX the Py* apps have a new item on the Options
 576 menu for controlling this setting if you would like to experiment with
 577 it.</p>
 578 <p>Updated wx.lib.calendar with many fixes and enhancements from Joerg
 579 &quot;Adi&quot; Sieker.</p>
 580 <p>Added wx.Display and wx.VideoMode.</p>
 581 <p>AppleEvents can be handled by overriding wx.App methods MacOpenFile,
 582 MacPrintFile, MacNewFile, and MacReopenApp.</p>
 583 <p>Added wx.PlatformInfo which is a tuple containing strings that
 584 describe the platform and build options of wxPython.  See the
 585 MigrationGuide for more details.</p>
 586 <p>Created a new extension module &quot;activex&quot; from Lindsay Mathieson's
 587 newest <a class="reference" href="http://members.optusnet.com.au/~blackpaw1/wxactivex.html">wxActiveX</a> class.  (The existing iewin module used an older
 588 version of this code, but only exposed the wxIEHtmlWin class.)  This
 589 new module will (in theory ;-) ) allow you to host arbitrary ActiveX
 590 controls in a wx.Window, <strong>without</strong> requiring the use of the win32com
 591 and other PyWin32 modules!  This should eliminate the cronic problems
 592 that have resulted from minor mismatches in how PyWin32 handles the
 593 GIL and tstate when making callbacks, etc.  The older iewin module
 594 will be left in this release as the new stuff is not fully backwards
 595 compatible, but you should migrate your code to the new IEHtmlWindow
 596 in wx.lib.iewin, so the old one can be eventually removed.
 597 Additionally, I've always considered that the wx.lib.activexwrapper
 598 module is an ugly hack that I only included in the lib because I
 599 couldn't figure out anything better.  Well now we have something that,
 600 if it isn't already, has the potential to be better.  So consider
 601 migrating away from using activexwrapper as well.  Please see the
 602 MigrationGuide for more details on using the new module.</p>
 603 <p>Floats are allowed again as function parameters where ints are expected.</p>
 604 </div>
 605 <div class="section" id="id7">
 606 <h1><a name="id7">2.4.2.4</a></h1>
 607 <p>Use wxSTC in the demo for displaying the soucre code of the samples.</p>
 608 <p>Lots of bug fixes and such from the wxWindows folks.</p>
 609 <p>Added wxPython.lib.newevent from Miki Tebeka.  Its usage is
 610 demonstrated in the Threads sample in the demo.</p>
 611 <p>Updates to wxMaskedEditCtrl.</p>
 612 <p>Added wxMaskedNumCtrl.</p>
 613 <p>Added Chris Barker's FloatCanvas.</p>
 614 </div>
 615 <div class="section" id="id8">
 616 <h1><a name="id8">2.4.1.2</a></h1>
 617 <p>Added wxScrolledPanel from Will Sadkin</p>
 618 <p>Added SetShape method to top level windows (e.g. wxFrame.)</p>
 619 <p>Changed wxSWIG to not generate Python code using apply, (since it will
 620 be deprecated in the future) wxSWIG will use <tt class="literal"><span class="pre">spam(*args,</span> <span class="pre">**kw)</span></tt> syntax
 621 instead.  Also changed the generated __repr__ methods to be a bit more
 622 informative.</p>
 623 <p>Made the version number information more robust and uh, informative.
 624 Also added asserts to check that the major.minor versions of wxPython
 625 and wxWindows match.</p>
 626 <p>Added the new wx &quot;renamer&quot; package that will dynamically import from
 627 the wxPython package and rename wxFooBar --&gt; FooBar.  That means that
 628 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
 629 wx.Frame instead of wx.wxFrame.  This is phase 1 of a full transition
 630 to the new namespace.</p>
 631 <p>Updated Scintilla to 1.52.  I also changed it to use wxListCtrl
 632 instead of wxListBox for the AutoComplete window, added the ability to
 633 use custom bitmaps in the margin and in the AutoComplete windows, and
 634 worked out how to do proper clipping of child windows on wxGTK.</p>
 635 <p>Patrick O'Brien's PyCrust package has been renamed to Py and now
 636 includes several new tools.  As part of the change the location of the
 637 pacakge has changed as well, it is now accessible as &quot;from wxPython
 638 import py&quot; (or &quot;from wx import py&quot; using the new namespace.)  There
 639 are still some transition modules in the wxPython.lib.PyCrust package
 640 that will issue a warning and then import what is needed from the new
 641 package.  These will be removed in a future release.</p>
 642 <p>Added __nonzero__ method to wxTreeItemId, wxBitmap, wxImage, wxFont,
 643 and most other classes that have an Ok or IsOK method.  This allows
 644 code like &quot;if obj: ...&quot; to be the same as &quot;if obj.IsOk(): ...&quot;</p>
 645 <p>Toolbars on wxMac can now have controls on them.</p>
 646 <p>Added wxPython.lib.analogclock module based on samples that were
 647 passed back and forth on wxPython-users a while back.</p>
 648 <p>Added masked edit controls (wxPython.lib.maskededit) by Jeff Childers
 649 and Will Sadkin.  Updated wxTimeCtrl to use MaskedEdit.</p>
 650 <p>When the __class__ of a dead object is replaced with _wxPyDeadObject
 651 the __del__ of the original class is now called first.</p>
 652 <p>Added wxTreeListCtrl.  (Looks like a wxTreeCtrl embedded in a
 653 wxListCtrl, but actually is just giving multiple columns to a
 654 wxTreeCtrl.)</p>
 655 <p>Added wxFutureCall, a subclass of wxTimer that makes it easy to delay
 656 a call to any Python callable object.</p>
 657 <p>Added wxPy versions of wxPrintPreview, wxPreviewFrame, and
 658 wxPreviewControlBar so they can be derived from in Python and be able
 659 to override the C++ virtual methods.</p>
 660 <p>Simplified how the wxSizer methods are wrapped, changed the name of
 661 the &quot;option&quot; parameter to &quot;proportion&quot; to match the docs (&quot;option&quot; is
 662 still accepted for compatibility, but this will go away in a future
 663 release,) SetItemMinSize can now take a wxSize (or 2-tuple) parameter,
 664 and Spacers can be specified with a wxSize (or 2-tuple) parameter</p>
 665 <p>Added wxCursorFromBits.</p>
 666 </div>
 667 <div class="section" id="id9">
 668 <h1><a name="id9">2.4.0.7</a></h1>
 669 <p>Gave up on generating a warning upon the use of the old true/false or
 670 TRUE/FALSE values.</p>
 671 <p>Fixed wxGenericTreeCtrl (used on wxGTK and wxMac for wxTreeCtrl) so
 672 that it can successfully handle lots of nodes instead of overflowing
 673 when the virtual height of the widget overflowed a 16-bit value.</p>
 674 <p>Fixed the typemap that converts strings to wxColours to also accept
 675 unicode.</p>
 676 <p>Fixed problem where the wrong class name could sometimes be used for
 677 OOR.</p>
 678 <p>Fixed an interpreter lock problem in the __eq__ and __ne__ methods in
 679 wxSize and etc.</p>
 680 <p>Updated PyCrust to version 0.9</p>
 681 <p>Instead of always logging C++ assertions, added wxPYAPP_ASSERT_LOG
 682 flag to turn it on.  In most cases turning it into an exception (the
 683 default behavior) is enough.  See below in the 2.3.4.1 notes for more
 684 details.</p>

 698 <div class="section" id="id10">
 699 <h1><a name="id10">2.4.0.4</a></h1>
 700 <p>Added missing wxRect methods</p>
 701 <p>Add OOR support for wxApp objects too.</p>
 702 <p>Added wxCursorFromImage, which works on wxMSW and wxGTK so far.</p>
 703 <p>All platforms now send EVT_DESTROY_WINDOW.  Be warned that at the time
 704 the event is sent the window is in the process of being deconstructed,
 705 and so calling some (most?) methods of the window itself may cause
 706 problems.</p>
 707 <p>Fixed SF Bug #689481, a method in the OGL wrappers was using the wrong
 708 return type.</p>
 709 <p>Fixed SF Bug #689958, an endless loop in printout.py.</p>
 710 <p>Added EVT_WINDOW_CREATE_ID and EVT_WINDOW_DESTROY_ID so these events
 711 can be associated with a specific window ID and more easily caught by
 712 the parent window.</p>
 713 <p>Fixed copy-paste error in wxListCtrl.GetFirstSelected.</p>
 714 <p>Added missing Init method (and an overloading wrapper) to wxLocale
 715 wrapper.</p>
 716 <p>Added a wxBitmap.SetMaskColour convenience method.</p>
 717 <p>Changed how the dynamic event tables (used for all Python wx classes,
 718 C++ wx classes typically use static event tables) are searched such
 719 that they behave from a Python perspective more like the static tables
 720 in C++.  Namely that if there are identical event bindings in a base
 721 Python class and a derived Python class that the one in the derived
 722 class will be found first and that if Skip is called that the one in
 723 the base class will still be found instead of skipping directly to the
 724 static stable in the C++ class.</p>
 725 <p>Switched to using True/False in the wxPython lib and demo instead of
 726 true/false or TRUE/FALSE to prepare for the new boolean type and
 727 constants being added to Python.  Added code to wx.py to test for the
 728 existence of the new constants and to create suitable values if not
 729 present.</p>
 730 <p>Added some static wxApp functions that help with integration with the
 731 Mac UI.  They are no-ops on other platforms so it doesn't hurt to
 732 always call them.  The functions are:</p>
 733 <blockquote>
 734 wxApp_GetMacDefaultEncodingIsPC
 735 wxApp_GetMacSupportPCMenuShortcuts
 736 wxApp_GetMacAboutMenuItemId
 737 wxApp_GetMacPreferencesMenuItemId
 738 wxApp_GetMacExitMenuItemId
 739 wxApp_GetMacHelpMenuTitleName
 740 wxApp_SetMacDefaultEncodingIsPC
 741 wxApp_SetMacSupportPCMenuShortcuts
 742 wxApp_SetMacAboutMenuItemId
 743 wxApp_SetMacPreferencesMenuItemId
 744 wxApp_SetMacExitMenuItemId
 745 wxApp_SetMacHelpMenuTitleName</blockquote>
 746 <p>Refactored, enhanced and added capabilities for the DrawXXXList
 747 functions, inspired by code from Chris Barker.</p>
 748 <p>The wxWindows .mo language catalog files are now installed in a
 749 subdirectory of the wxPython package dir on MSW since that platform
 750 doesn't have a standard place for them.</p>
 751 <p>Added missing deselect methods for wxGrid.</p>
 752 <p>Fixed typemaps for wxGridCellCoordsArray.</p>
 753 <p>Updated to the 0.9a version of PyCrust</p>
 754 </div>
 755 <div class="section" id="id11">
 756 <h1><a name="id11">2.4.0.2</a></h1>

 775 <p>Show a couple new wxGrid features in the demo.</p>
 776 <p>Several bug fixes in wxWindows.</p>
 777 <p>Added wxHtmlFilter.</p>
 778 <p>wxASSERT and related C++ runtime diagnostics are now converted to
 779 Python exceptions.  When an assert happens a wxPyAssertionError
 780 (which derives from AssertionError) exception is created and when
 781 control returns back to the Python code that invoked the C++ API it
 782 will be raised.  The same exception restrictions are in place as
 783 before, namely that exceptions can't cross from one Python layer
 784 through C++ to another Python layer.  That simply means that if you
 785 want to catch wxPyAssertionError or any other exception that you need
 786 to do it before control returns to C++ at the end of your event
 787 handler or callback code.  There is some test code in demo/wxButton.py
 788 you can use to play with this new feature.</p>
 789 <p>Added some methods to wxApp (SetAssertMode and GetAssertMode) that let
 790 you control how C++ assertions are processed.  Valid modes are:
 791 wxPYAPP_ASSERT_SUPPRESS, wxPYAPP_ASSERT_EXCEPTION, and
 792 wxPYAPP_ASSERT_DIALOG.  Using _SUPPRESS will give you behavior like
 793 the old &quot;final&quot; builds and the assert will be ignored, _EXCEPTION is
 794 the new default described above, and _DIALOG is like the default in
 795 2.3.3.1 and prior &quot;hybrid&quot; builds.  You can also combine _EXCEPTION
 796 and _DIALOG if you wish, although I don't know why you would.</p>
 797 <p>You can now overload OnInitGui, OnExit and OnAssert in your classes
 798 derived from wxApp.</p>
 799 <p>Added GetSelectedCells, GetSelectionBlockTopLeft,
 800 GetSelectionBlockBottomRight, GetSelectedRows, GetSelectedCols nethods
 801 to wxGrid.</p>
 802 <p>Added Python == and != operators for some basic classes</p>
 803 <p>Fixed the Python wrappers for wxInputStream so they no longer block
 804 when reading from a wxProcess on wxGTK.  They now work more or less as
 805 they did before 2.3.3.1 but the dual meaning of eof() has been
 806 removed.  There is now a CanRead() method that lets you know if there
 807 is data waiting to be read from the pipe.</p>
 808 <p>Fixed method name clash in wxIEHtmlWin, renamed Refresh to RefreshPage.</p>
 809 <p>Added Throbber from Cliff Wells to the library and the demo.</p>
 810 <p>Windows installer prompts to uninstall old version first.</p>
 811 <p>Added wxPython.lib.evtmgr by Robb Shecter, which is an easier, more
 812 &quot;Pythonic&quot; and more OO method of registering handlers for wxWindows
 813 events using the Publish/Subscribe pattern.</p>
 814 <p>Added wxPython.lib.popupctl by Gerrit van Dyk which is a combobox-like
 815 gizmo for poping up arbitrary controls.  It is currently using
 816 wxDialog because of some issues with wxPopupWindow...</p>
 817 <p>Added wxPython.lib.gridmovers by Gerrit van Dyk which facilitates the
 818 dragging of columns and/or rows in a wxGrid.</p>
 819 <p>Added wxPython.lib.multisash by Gerrit van Dyk which is a nice
 820 implementation of allowing the user to split a window any number of
 821 times either horizontally or vertically, and to close the split off
 822 windows when desired.</p>
 823 <p>Added helpviewer tool that displays HTML books similarly to how MS
 824 HTMLHelp viewer does.  Changed how the wxPythonDocs tarball is built
 825 and added a script to launch the doc viewer.</p>
 826 </div>
 827 <div class="section" id="id15">
 828 <h1><a name="id15">2.3.3.1</a></h1>
 829 <p>Added wxSplashScreen.</p>
 830 <p>Added wxGenericDirCtrl.</p>
 831 <p>Added wxMultiChoiceDialog.</p>
 832 <p>The calltip window and autocomplete window in wxSTC will now use a
 833 wxPopupWindow if available on the platform (and functioning correctly)
 834 so they can extend beyond the client area of the STC if needed.</p>
 835 <p>Finished wrapping and providing typemaps for wxInputStream and also
 836 added the stream ctor and other methods for wxImage so images can now
 837 be loaded from any Python &quot;file-like&quot; object.</p>
 838 <p>Changed the img2py tool to use PNG instead of XPM for embedding image
 839 data in Python source code, and the generated code now uses streams to
 840 convert the image data to wxImage, wxBitmap, or wxIcon.</p>
 841 <p>Added the wxPython.lib.rcsizer module which contains RowColSizer.
 842 This sizer is based on code from Niki Spahiev and lets you specify a
 843 row and column for each item, as well as optional column or row
 844 spanning.  Cells with no item assigned to it are just left blank.
 845 Stretchable rows or columns are specified and work the same as in
 846 wxFlexGridSizer.</p>
 847 <p>Updated XRCed from Roman Rolinsky</p>
 848 <p>Added wxBufferedDC.</p>
 849 <p>Upgraded wxSTC from Scintilla 1.40 to Scintilla 1.45, and then again
 850 to version 1.47, and one more time to 1.48! &lt;wink&gt;</p>
 851 <dl>
 852 <dt>UNICODE!</dt>
 853 <dd><p class="first">wxWindows/wxPython can be compiled with unicode support enabled or
 854 disabled.  Previous to wxPython 2.3.3 non-unicode mode was always
 855 used.  Starting with 2.3.3 either mode is supported, but only if
 856 it is also available in wxWindows on the platform.  Currently
 857 wxWindows only supports unicode on MS Windows platforms, but with
 858 the recent release of GTK+ 2.0 it is only a matter of time until
 859 it can be done on wxGTK (Linux and other unixes) as well.</p>
 860 <p>Unicode works best on platforms in the NT branch of the Windows
 861 family tree (NT, win2k, XP) but it is now also possible to use the
 862 same unicode binaries on win95/98/ME platforms as well!  This is
 863 done by using a special library and DLL with the application
 864 called MSLU, (Microsoft Layer for Unicode).  It simply gets out of
 865 the way if the app is run on an NT box, otherwise if run on a
 866 win9x box it loads a special DLL that provides the unicode
 867 versions of the windows API.  So far I have not been able to get
 868 this to work perfectly on win9x.  Most things work fine but
 869 wxTaskBarIcon for example will cause a crash if used with the
 870 unicode build on win95.</p>
 871 <p class="last">So how do you use it?  It's very simple.  When unicode is enabled,
 872 then all functions and methods in wxPython that return a wxString
 873 from the C++ function will return a Python unicode object, and
 874 parameters to C++ functions/methods that expect a wxString can
 875 accept either a Python string or unicode object.  If a string
 876 object is passed then it will be decoded into unicode using the
 877 converter pointed to by wxConvCurrent, which will use the default
 878 system encoding.  If you need to use a string in some other
 879 encoding then you should convert it to unicode using the Python
 880 codecs first and then pass the unicode string to the wxPython
 881 method.</p>
 882 </dd>
 883 </dl>
 884 <p>Added wxListCtrlAutoWidthMixin from Erik Westra.</p>
 885 <p>Added wxIconBundle and wxTopLevelWindow.SetIcons.</p>
 886 <p>Added wxLocale and wxEncodingConverter.</p>
 887 <p>A little black magic...  When the C++ object (for a window or
 888 whatever) is deleted there is no way to force the Python shadow object
 889 to also be destroyed and clean up all references to it.  This leads to
 890 crashes if the shadow object tries to call a method with the old C++
 891 pointer.  The black magic I've done is to replace the __class__ in the
 892 Python instance object with a class that raises an exception whenever
 893 a method call (or other attribute access) is attempted.  This works
 894 for any class that is OOR aware.</p>
 895 <p>Added OOR support for wxGridCellRenderer, wxGridCellEditor,
 896 wxGridCellAttr, wxGridCellAttrProvider, wxGridTableBase and their
 897 derived classes.</p>
 898 <p>Added wxImage.GetDataBuffer which returns an in-place edit buffer of
 899 the image data.  (Patch #546009)</p>
 900 <p>Added a sample that shows how to embed wxPython in a wxWindows C++
 901 application.</p>
 902 <p>Added wxPyWindow, wxPyPanel and wxPyControl which are just like their
 903 wx counterparts except they allow some of the more common C++ virtual
 904 methods to be overridden in Python derived classes.  The methods
 905 supported are:</p>
 906 <blockquote>
 907 <p>DoMoveWindow
 908 DoSetSize
 909 DoSetClientSize
 910 DoSetVirtualSize
 911 DoGetSize
 912 DoGetClientSize
 913 DoGetPosition
 914 DoGetVirtualSize
 915 DoGetBestSize
 916 InitDialog
 917 TransferDataFromWindow
 918 TransferDataToWindow
 919 Validate
 920 AcceptsFocus
 921 AcceptsFocusFromKeyboard
 922 GetMaxSize
 923 AddChild
 924 RemoveChild</p>
 925 <p>If there are other methods that you think should be supported
 926 please let me know.</p>
 927 </blockquote>
 928 <p>Changed wxGenButton to derive from wxPyControl and overload
 929 DoGetBestSize and AcceptsFocus.</p>
 930 <p>Added wxArtProvider.</p>
 931 <p>Added wxCallAfter which is a helper function that registers a function
 932 (or any callable Python object) to be called once the next time there
 933 are no pending events.  This is useful for when you need to do
 934 something but it can't be done during the current event handler.  The
 935 implementation is very simple, see wxPython/wx.py.</p>
 936 <p>Fixed a boatload of reference leaks.</p>
 937 <p>Added a demo of using a sizer in a wxScrolledWindow, in effect
 938 creating a ScrolledPanel.</p>
 939 <p>Added a sample to the demo that shows how to use radio menu items, and
 940 other menu stuff.</p>
 941 <p>Added wxIEHtmlWin.  This is essentially the same as using IE with the
 942 ActiveXWrapper already in the library, but it is implemented all in
 943 C++ and therefore does not need any of the modules from win32all and
 944 so it is less fragile in the face of changes.</p>
 945 <p>Fixed the ActiveXWrapper problem.  Looks like when the win32com
 946 modules make a &quot;callback&quot; that they (incorrectly, IMHO) allocate a
 947 transient thread state structure.  Since wxPython is now saving
 948 tstates for it's own callbacks it ended up using garbage after
 949 win32com got rid of the temporary tstate...</p>
 950 <p>Added a generic static text control to wxPython.lib.stattext.  This is
 951 so things like Boa and PythonCard can have a static text that can
 952 respond to mouse events and etc.</p>
 953 <p>Changed the wxDateTime.Parse* methods to return an int that will be -1
 954 on failure, and the index where parsing stopped otherwise.</p>
 955 <p>Moved tools to be a Python package in wxPython.tools, added scripts to
 956 import and launch each tool.  This will let you import and use the
 957 tools in your own scripts or apps as needed.  On Linux and OS X the
 958 tool scripts are installed to {prefix}/bin so you should be able to
 959 easily launch them from the command line.  For example, PyCrust can be
 960 started with just the &quot;pycrust&quot; command.</p>
 961 <p>Added a sample to the demo that catches various key events and
 962 displays the details of the event.</p>
 963 <p>Added wxWizard, wxWizardPage, wxWizardPageSimple and wxPyWizardPage.</p>
 964 <p>Added wxXmlResourceHandler which allows you to create custom handlers
 965 for nonstandard class types in XRC resources.  See the demo for an
 966 example.</p>
 967 <p>Added wxPython.lib.mixins.rubberband module from Robb Shecter.</p>
 968 <p>Added wxTimeCtrl from Will Sadkin.</p>
 969 </div>
 970 <div class="section" id="id16">
 971 <h1><a name="id16">2.3.2.1</a></h1>
 972 <p>Changed (again) how the Python global interpreter lock is handled as
 973 well as the Python thread state.  This time it works on SMP machines
 974 without barfing and is also still compatible with Python debuggers.</p>
 975 <p>Added some patches from library contributors.</p>
 976 </div>
 977 <div class="section" id="id17">
 978 <h1><a name="id17">2.3.2</a></h1>
 979 <p>Added EVT_HELP, EVT_HELP_RANGE, EVT_DETAILED_HELP,
 980 EVT_DETAILED_HELP_RANGE, EVT_CONTEXT_MENU, wxHelpEvent,
 981 wxContextMenuEvent, wxContextHelp, wxContextHelpButton, wxTipWindow,
 982 and a demo to show them in action.</p>
 983 <p>Deprecated PyShell and PyShellWindow, added a snapshot of PyCrust (see
 984 <a class="reference" href="http://sourceforge.net/projects/pycrust/">http://sourceforge.net/projects/pycrust/</a>. )</p>
 985 <p>Added the new virtual list capabilities to wxListCtrl.</p>
 986 <p>Added a wxSTC style editor from Riaan Booysen to the sample apps.</p>
 987 <p>Added XRCed to the wxPython Tools directory, contributed by Roman
 988 Rolinsky.</p>
 989 <p>Added a new &quot;constructor&quot; to most of the window classes that calls the
 990 default C++ constructor, (the one with no parameters) and also added the
 991 corresponding  Create(...) method.  This allows you to do a 2-step
 992 creation of windows which is sometimes required for doing things such
 993 as setting extended style flags before the window is created, or for
 994 passing the object to the XRC resource system to be created from the
 995 resource.  The name of the new &quot;constructor&quot; is the original name of
 996 the class with a &quot;Pre&quot; in it.  For example, wxPreWindow, wxPreFrame,
 997 etc.</p>
 998 <p>Updated to version 1.40 of Scintilla and updated wxStyledTextCtrl
 999 accordingly.  While doing this update I dropped the wxLB_SORT style
1000 from the wxListBox created for the AutoComplete functionality.  This
1001 means that you will have to sort the keyword lists yourself, but you
1002 are free to do case sensitive or case insensitive sorts and set the
1003 wxSTC flag accordingly.</p>
1004 <p>Updated wxColumnSorterMixin to also be able to place sort icons on the
1005 column headers, and updated the wxListCtrl demo to show it off by
1006 using wxColumnSorterMixin.</p>
1007 <p>Added wxGenBitmapTextButton, TablePrint, etc. contribs from Lorne White.</p>
1008 <p>Added wxNativeFontInfo and wxFontMapper.</p>
1009 <p>Added pySketch to the samples.</p>
1010 <p>Significantly changed how the Python interpreter lock and thread state
1011 are managed, which should fix the problem of running on a
1012 multi-processor machine.</p>
1013 <p>Added wxPyLog so log targets can be created in Python to handle log
1014 messages however is wished.  See demo/Main.py for an example.</p>
1015 <p>Added wxFindReplaceDialog.</p>
1016 <p>The second phase of OOR is implemented for wxEvtHandler, wxSizer,
1017 wxShape and derived classes.  This means that functions and methods
1018 that return an object derived from wxEvtHandler that was originally
1019 created in Python, will return the original Python object (if it still
1020 exists) instead of letting SWIG wrap a new shadow object around the
1021 original C++ pointer.</p>
1022 <p>Added some optimization methods to wxDC: GetBoundingBox, DrawLineList,
1023 DrawPointList.</p>
1024 <p>Added a set of sophisticated Error Dialogs from Chris Fama.</p>
1025 <p>Added wxRightTextCtrl from Josu Oyanguren to wxPython.lib for aligning
1026 text in a wxTextCtrl to the right side.</p>
1027 <p>Added wxURLDataObject and an example showing drag and drop of URLs to
1028 and from web browsers.  It's still not 100% bullet-proof for all types
1029 of browsers, but it works for the majority of cases with the popular
1030 browsers on Windows.  On wxGTK it seems that only Netscape 4.x works,
1031 if anybody has any suggestions about this please bring it up on the
1032 wx-dev list.</p>
1033 <p>Added wxStopWatch.</p>
1034 <p>Added wxMimeTypesManager and wxFileType.</p>
1035 <p>Passing None for the handler parameter to one of the EVT_** functions
1036 will now Disconnect the event.</p>
1037 <p>Added wxPopupWindow and wxPopupTransientWindow.</p>
1038 <p>Added wxFileHistory.</p>
1039 <p>Added wxDynamicSashWindow, which allows you to endlessly split windows
1040 by dragging a little tab next to the scrollbars.  Added a demo to show
1041 this and also the ability of multiple wxStyledTextCtrls to share the
1042 same document.</p>
1043 <p>Added wxEditableListBox gizmo.</p>
1044 <p>Updated wxEditor with lots of enhancements from Steve Howell and Adam
1045 Feuer.</p>
1046 <p>Added the &quot;SplitTree gizmos&quot; which are a collection of classes that
1047 were designed to operate together and provide a tree control with
1048 additional columns for each item.  The classes are
1049 wxRemotelyScrolledTreeCtrl, wxTreeCompanionWindow,
1050 wxThinSplitterWindow, and wxSplitterScrolledWindow, some of which may
1051 also be useful by themselves.</p>
1052 <p>Added wxDllWidget from Vaclav Slavik which allows wx widgets derived
1053 from wxWindow to be loaded from a C++ .dll (or .so) and be used in a
1054 wxPython program, without the widget having to be SWIGged first.  The
1055 visible API of the widget is limited to wxWindow methods plus a
1056 SendCommand method, but it is still quite powerful.  See
1057 wxPython/contrib/dllwidget and wxPython/demo/dllwidget for more
1058 details.</p>
1059 </div>
1060 <div class="section" id="id18">
1061 <h1><a name="id18">2.3.1</a></h1>
1062 <p>Added EVT_GRID_EDITOR_CREATED and wxGridEditorCreatedEvent so the user
1063 code can get access to the edit control when it is created, (to push
1064 on a custom event handler for example.)</p>
1065 <p>Added wxTextAttr class and SetStyle, SetDefaultStyle and
1066 GetDefaultStyle methods to wxTextCtrl.</p>
1067 <p>Added ability to use xml resource files.  Still need to add ability to
1068 subclass wxXmlResourceHandler, etc...</p>
1069 <p>Added wxGridAutoEditMixin to the mixins library package.</p>
1070 <p>Made ColourSelect be derived from wxButton.</p>
1071 <p>Fixed img2py to work correctly with Python 2.1.</p>
1072 <p>Added enhanced wxVTKRenderWindow by Prabhu Ramachandran</p>
1073 </div>
1074 <div class="section" id="id19">
1075 <h1><a name="id19">2.3.0</a></h1>
1076 <p>Removed initial startup dependency on the OpenGL DLLs so only the
1077 glcanvasc.pyd depends on them, (on wxMSW.)</p>
1078 <p>Changed wxFont, wxPen, wxBrush to not implicitly use the
1079 wxThe[Font|Pen|Brush]List objects behind the scenes, but to use normal
1080 ctor and dtors.</p>
1081 <p>Exposed the wxThe[Font|Pen|Brush]List to wxPython.</p>
1082 <p>Also added wxTheColourDatabase and added a library module (in the
1083 wxPython.lib.colourdb module) to load LOTS more colour names into the
1084 colour database.</p>
1085 <p>Added wxWakeUpMainThread, wxMutexGuiEnter, wxMutexGuiLeave,
1086 wxMutexGuiLocker and wxThread_IsMain to assist with dealing with GUI
1087 access from non-GUI threads.</p>
1088 <p>wxPyOnDemandOutputWindow is now (more) thread safe if non-GUI threads
1089 use print, sys.stdout.write, etc.</p>
1090 <p>Added CreateTextSizer and CreateButtonSizer to wxDialog</p>
1091 <p>Added wxPython/lib/infoframe.py from Chris Fama.  It contains a class
1092 that can be used in place of wxPyOnDemandOutputWindow.</p>
1093 <p>Added colourselect.py, imagebrowser.py and an updated calendar.py to
1094 wxPython/lib from Lorne White.</p>
1095 <p>Added patch to wxPoint_LIST_helper from Tim Hochberg that should make
1096 it gobs faster in certain situations.</p>
1097 <p>Added tools that will take an image file in a wx supported format and
1098 convert it to data embedded in a Python source file.  The image is
1099 converted to XPM format which is essentially a list of strings
1100 containing info about each pixel.  The image's transparency mask is
1101 included, if there is one, or a mask can be added if a mask colour is
1102 specified on the command line.  It is then pickled and optionally
1103 compressed and written to a Python source file along with functions to
1104 convert it to either a wxBitmap or a wxImage.  See
1105 wxPython/demo/images.py for examples, and wxPython/Tools/img2py.py for
1106 the implementation.</p>
1107 <p>Fixed wxStyledTextCtrl to be much faster on wxGTK.  There was some
1108 experimental code that got left in place that ended up causing way too
1109 many refreshes.</p>
1110 <p>A couple more hacks in my_distutils.py so wxPython can be built with
1111 the distutils that comes with Python 2.1.</p>
1112 <p>Added a ton of missing methods for wxPrintData.</p>
1113 <p>Switched to InnoSetup for MSW distributions.</p>
1114 <p>Added wxToggleButton.</p>
1115 <p>Fixed bug that prevented wxTreeCtrl.OnCompareItems from being called.</p>
1116 <dl>
1117 <dt>Added some methods to wxGrid:</dt>
1118 <dd>GetCellHighlightPenWidth
1119 GetCellHighlightROPenWidth
1120 SetCellHighlightPenWidth
1121 SetCellHighlightROPenWidth
1122 GetGridWindow
1123 GetGridRowLabelWindow
1124 GetGridColLabelWindow
1125 GetGridCornerLabelWindow</dd>
1126 </dl>
1127 <p>Added wxGetClientDisplayRect which on wxMSW returns a wxRect
1128 representing the area on screen not occupied by the taskbar and such.
1129 On other platforms it is equivallent to wxGetDisplaySize.</p>
1130 <dl>
1131 <dt>OOR:</dt>
1132 <dd><p class="first">Implemented the first phase of OOR (Original Object Return).  See
1133 the text in the demo for more details of what this means, but in a
1134 nutshell methods such as wxWindow.GetParent or FindWindowById will
1135 now return a shadow object of the proper type if it can.  By
1136 &quot;proper type&quot; I mean that if the wxWindow pointer returned from
1137 FindWindowById really points to a wxButton then the Python object
1138 constructed will be of a wxButtonPtr class instead of wxWindowPtr
1139 as before.  This should reduce or eliminiate the need for
1140 wxPyTypeCast.  (Woo Hoo!)  The objects returned are still not the
1141 original Python object, but that is the next step.  (Although it
1142 will probably only work on Python 2.1 and beyond because it will
1143 use weak references.)</p>
1144 <p class="last">This first phase of the OOR plan is fairly significant and has
1145 required a lot of changes all over wxPython, most of which should
1146 be transparent to you, however I'm not 100% sure that it didn't
1147 introduce any new bugs that are hiding somewhere and didn't get
1148 stomped on during my testing.  So please be sure to test everything
1149 thoroughly when you install this version and be sure to report any
1150 object-type related oddities to me.</p>
1151 </dd>
1152 </dl>
1153 <p>There is now a wxObject class that most other classes derive from like
1154 in C++, but the methods provided don't really match but are wxPython
1155 specific.  It could have been added long ago but OOR required it so it
1156 finally got done.</p>
1157 <p>Finally added wxPyLineShape.GetLineControlPoints, which has been on my
1158 list for a while.  The above OOR modification made this easier.</p>
1159 <p>Fixed the __cmp__ methods for wxPoint and others.</p>
1160 <p>Added wxWave.</p>
1161 <p>Added the wxPython.lib.mixins package to the library, it is where
1162 useful mix-in classes can be placed.  Currently there is one to help
1163 make the columns in a wxListCtrl sortable, and the MagicIMageList from
1164 Mike Fletcher.  If you have any custom code that can be factored out
1165 of existing classes into a mix-in that would be useful to others
1166 please send it to me for inclusion in this package.</p>
1167 <p>Added a few little sample applications to help newbies to get started
1168 by having smaller functional apps to play with.  They can be found in
1169 wxPython/samples.</p>
1170 </div>
1171 <div class="section" id="id20">
1172 <h1><a name="id20">2.2.6</a></h1>
1173 <p>No changes happened in the Python wrappers for this release, only
1174 changes and fixes in the wxWindows library.</p>
1175 </div>
1176 <div class="section" id="id21">
1177 <h1><a name="id21">2.2.5</a></h1>
1178 <p>New typemaps for wxString when compiling for Python 2.0 and beyond
1179 that allow Unicode objects to be passed as well as String objects.  If
1180 a Unicode object is passed PyString_AsStringAndSize is used to convert
1181 it to a wxString using the default encoding.</p>
1182 <p>Fixed the generic buttons so tool tips work for them.</p>
1183 <p>Fixed a bug in the demo's tree control.</p>
1184 <p>Added a listbox to the listbox demo that shows how to find items with
1185 a matching prefix as keys are typed.</p>
1186 <p>Added code to the wxListCtrl demo to show how to get text from a
1187 column in report mode.</p>
1188 <p>Added code to the toolbar demo to clear the long help from the status
1189 bar after 2 seconds.</p>
1190 <p>Added wxJoystick.</p>
1191 <p>Fixed wxTimer so it can be used as described in the docs, either with
1192 a Notify method in a subclass, or sending an event to a wxEvtHandler
1193 object, (usually a window.)</p>
1194 <p>Added wxNotifyEvent.Allow()</p>
1195 <p>Fixed GOBS of reference leaks.</p>
1196 <p>Massive code changes and cleanup to allow wxPython to be split into
1197 multiple extension modules again.  A Python CObject is used to allow
1198 the &quot;export&quot; of SWIG functions and other common helper functions from
1199 the wxc module to other modules, even if they are in separate shared
1200 libraries.  Should also be usable from 3rd party code, just include
1201 wxPython/src/export.h</p>
1202 <p>Changed the default setup so the following are built as separate
1203 extension modules:  calendar, glcanvas, grid, html, ogl, stc, and
1204 utils.  Will probably add more later.</p>
1205 <p>Changed the wxPrinterDC to use the new constructor taking a
1206 wxPrintData object.  The old ctor is still there using the
1207 wxPrinterDC2 name.</p>
1208 <p>Added wxPython.lib.anchors.py from Riaan Booysen.  It contains a class
1209 that implements Delphi's Anchors with wxLayoutConstraints.</p>
1210 <p>Added wxPython.lib.fancytext from Timothy Hochberg.</p>
1211 <p>Changed the GenericButtons to send their event in idle time, so the
1212 mouse won't be captured when the event handler is called.</p>
1213 <p>Added wxPython.lib.rpcMixin from Greg Landrum, although it's not
1214 integrated with the demo yet.  It allows a wxPython GUI to be an
1215 XML-RPC server.</p>

1218 <h1><a name="new-in-2-2-2">New in 2.2.2</a></h1>
1219 <p>Significantly changed how the wxStyledtextCtrl code that wraps
1220 Scintilla is implemented.  Most of it is now automatically generated
1221 from an interface definition file provided by Scintilla.  This means
1222 that it will be much easier to stay in sync with new Scintilla
1223 releases, but also means that some of the method and identifier names
1224 have changed.  See wxPython/demo/data/stc.h for a copy of the C++
1225 interface from which the Python interface is generated.  There is now
1226 some inline documentation in that file that should really help explain
1227 how things work.</p>
1228 <p>I am now using the Python Distutils to build wxPython and to make some
1229 of the distribution files.  (See <a class="reference" href="http://www.python.org/sigs/distutils-sig/">http://www.python.org/sigs/distutils-sig/</a>)
1230 This means no more messing with my kludgy build.py/Makefile hack,
1231 builds will be more consistent with other Python extensions that also
1232 use Distutils, and will hopefully make wxPython easier to build for
1233 platforms where there have been troubles before.  If you are building
1234 wxPython for Python 1.5.2 or for 1.6, then you will need to get and
1235 install version 1.0 of Distutils from the website above.  If you are
1236 using Python 2.0 then you already have it.</p>
1237 <p>Added wxInputStream and the wxFileSystem family of classes,
1238 contributed by Joerg Baumann.</p>
1239 <p>Added wxProcess and support for it to wxExecute.  wxProcess lets you
1240 get notified when an asyncronous child process terminates, and also to
1241 get input/output streams for the child process's stdout, stderr and
1242 stdin.</p>
1243 <p>Removed the old python sizers.</p>
1244 <p>Added __add__, __sub__ and __cmp__ (equality check only) for wxPoint
1245 and wxRealPoint.</p>
1246 <p>Changed the build to make one big extension module instead of one for
1247 the core and each contrib.  This allowed me to do away with the
1248 libwxPyHelpers.so on unix systems.</p>
1249 <p>Lots of little fixes here and there.</p>
1250 <p>Some hacks on wxGTK to try and make the AutoComplete listbox in the
1251 wxStyledTextCtrl to behave better.  It's still not as nice as on
1252 wxMSW, but at least it's a bit more usable now.</p>

1276 <p>WARNING: A while back I asked what should be done about the Magic
1277 Method Names.  (Methods that are automatically turned into event
1278 handlers by virtue of their name.)  The consensus was that it is more
1279 confusing to have them than to try and expand them to have greater
1280 coverage.  I am finally getting around to removing the code that
1281 generates the event binding.  This means that if you are using any of
1282 the following method names without a EVT_* call that you need to
1283 modify your code to add the EVT_* to hook the event to the method.</p>
1284 <blockquote>
1285 OnChar
1286 OnSize
1287 OnEraseBackground
1288 OnSysColourChanged
1289 OnInitDialog
1290 OnPaint
1291 OnIdle

1299 <h1><a name="new-in-2-1-15">New in 2.1.15</a></h1>
1300 <p>Fixed wxTreeCtrl.HitTest to return both the tree item as well as the
1301 flags that clairify where the click was in relation to the item.</p>
1302 <p>Fixed thread state problem in wxTreeCtrl.GetBoundingBox and
1303 GetSelections.</p>
1304 <p>Fixed some problems in OGL.  Also wxShape.SetClientData and
1305 .GetClientData can now deal with Python objects.</p>
1306 <p>Added wxListCtrl.SortItems and changed the demo to show how to use it.</p>
1307 <p>Plugged a memory leak.</p>
1308 <p>Wrapped the new wxGrid and friends.  The old wxGrid class is no longer
1309 available.  There are some incompatibilities, and unfortunately the
1310 new classes are not documented yet, (however the methods are more
1311 consistent with each other now so you may be able to guess pretty
1312 good...)</p>
1313 <p>Updated filebrowsebutton.py and calendar.py with changes from their
1314 authors.  There is now a FileBrowseButtonWithHistory class (what a
1315 mouthful!) and wxCalendar has printing support.</p>
1316 <p>Added ActiveXWrapper to the library, and some good demos of it too.
1317 It works great for embedding a COM (a.k.a OCX, a.k.a ActiveX) control
1318 in a window and calling its methods.  It actually creates a new class
1319 on the fly that derives from wxWindow, the COM CoClass and others
1320 needed to make it all work.  The resulting class can be instantiated
1321 just like wxWindow, used in sizers, etc.  It also responds to all COM
1322 method calls, properties, etc., and if the class or a mix-in has
1323 matching method names, then the COM events will be propogated back to
1324 them.</p>
1325 <p>Created a typemap that allows a string to be used for parameters
1326 expecting a wxColour type.  The string is either a colour name as
1327 defined in the wxColourDatabase, or a colour spec of the form
1328 &quot;#RRGGBB&quot;.  See the wxStyledTextCtrl demo for an example.</p>
1329 <p>I almost forgot to mention the wxStyledTextCtrl!  Yes, the
1330 wxStyledTextCtrl is finally in wxPython!!  (And the crowd goes
1331 wild...)   There's no documentaTion yet (the crowd boos and hisses...)
1332 but I've included a very readable source file in the
1333 wxPython/demo/data directory, a couple fairly good examples, and you
1334 can also refer to the Scintilla documentaion at
1335 <a class="reference" href="http://www.scintilla.org/ScintillaDoc.html">http://www.scintilla.org/ScintillaDoc.html</a> to help fill in the gaps
1336 until the docs are done.  (The croud murmers contentedly as the tool
1337 provider smiles convincingly and removes his flame-proof suit.)</p>

1340 <h1><a name="what-s-new-in-2-1-13">What's new in 2.1.13</a></h1>
1341 <p>Skipped a version number to match what has been released for wxGTK.</p>
1342 <p>Updated wxMVCTree and added a demo for it, also fixed layout on GTK
1343 and some flicker problems.</p>
1344 <p>Added a wrapper class for the Visualization ToolKit (or VTK) in the
1345 wxPython.lib.vtk module.  (<a class="reference" href="http://www.kitware.com/">http://www.kitware.com/</a>)</p>
1346 <p>Fixed wxTreeCtrl.SetItemImage and GetItemImage to recognise the new
1347 &quot;which&quot; parameter.</p>
1348 <p>Added wxPython.lib.spashscreen from Mike Fletcher.</p>
1349 <p>Added wxPython.lib.filebrowsebutton also from Mike Fletcher.</p>
1350 <p>Renamed wxTreeCtrl.GetParent to GetItemParent to avoid a name clash
1351 with wxWindow.GetParent.</p>
1352 <p>Added wxIntersectRect to compute the intersection of two wxRect's.
1353 It is used like this:</p>
1354 <blockquote>
1355 intersect = wxIntersectRect(rect1, rect2)</blockquote>
1356 <p>If r1 and r2 don't intersect then None is returned, otherwise the
1357 rectangle representing the intersection is returned.</p>
1358 <p>Some bug fixes for Clipboard and Drag-n-Drop.</p>
1359 <p>Rotated text!!!  WooHoo!  (See wxDC.DrawRotatedText())</p>
1360 <p>Added a set of Generic Buttons to the library.  These are simple
1361 window classes that look and act like native buttons, but you can have
1362 a bit more control over them.  The bezel width can be set in addition
1363 to colours, fonts, etc.  There is a ToggleButton as well as Bitmap
1364 versions too.  They should also serve as a good example of how to
1365 create your own classes derived from wxControl.</p>
1366 <p>The C++ wxToolBar classes have been redone, and so have the wxPython
1367 wrappers.  There have been slight modifications to some of the methods
1368 but shouldn't impact anybody too much.  I took the opportunity to add
1369 support for setting user data on each toolbar tool.  The new AddTool
1370 methods look like this:</p>
1371 <blockquote>
1372 <dl>
1373 <dt>def AddTool(ID,</dt>
1374 <dd>bitmap,
1375 pushedBitmap = wxNullBitmap,
1376 toggle = FALSE,
1377 clientData = NULL,
1378 shortHelpString = &quot;&quot;,
1379 longHelpString = &quot;&quot;)</dd>
1380 <dt>def AddSimpleTool(ID,</dt>
1381 <dd>bitmap,
1382 shortHelpString = &quot;&quot;,
1383 longHelpString = &quot;&quot;,
1384 toggle=FALSE)</dd>
1385 </dl>
1386 </blockquote>
1387 <p>There are also corresponding InsertTool and InsertSimpleTool methods
1388 that additionally take an integer position as the first parameter.</p>
1389 <p>Added a wrapper for the new PCX and TIFF ImageHandlers.</p>
1390 <p>wxRect now simulates attributes named left, right, top and bottom.</p>
1391 <p>Removed all non wx stuff from the glcanvas module since DA's PyOpenGL
1392 is better and compatible with the wxGLCanvas.  You can get it at
1393 <a class="reference" href="http://starship.python.net:9673/crew/da/Code/PyOpenGL">http://starship.python.net:9673/crew/da/Code/PyOpenGL</a>.</p>
1394 <p>Added some missing EVT functions.</p>
1395 <p>Added Dirk Holtwic's editor classes to the wxPython.lib.editor
1396 package.</p>
1397 <p>Changed all the &quot;LIST&quot; parameter names to &quot;choices&quot; to match the docs.</p>
1398 <p>More fixes for the wxFloatBar, and it now works on wxGTK even better
1399 than wxMSW!  (The feat is accomplished by using the wxTB_DOCKABLE
1400 style flag instead of trying to float it ourselves.)</p>
1401 </div>
1402 <div class="section" id="what-s-new-in-2-1-11">
1403 <h1><a name="what-s-new-in-2-1-11">What's new in 2.1.11</a></h1>
1404 <p>Skipped a few version numbers so wxMSW, wxGTK and wxPython are all
1405 syncronized.</p>
1406 <p>wxImage.SetData now makes a copy of the image data before giving it to
1407 wxImage.  I mistakenly thought that wxImage would copy the data
1408 itself.</p>
1409 <p>Fixed wxMSW's notebook so the pages get their size set as they are
1410 being added.  This should remove the need for our
1411 wxNotebook.ResizeChildren hack.</p>
1412 <p>wxPanels now support AutoLayout, and wxNotebooks and wxSplitterWindows
1413 no longer tell their children to Layout() themselves.  This will
1414 probably only effect you if you have a wxWindow with AutoLayout inside
1415 a notebook or splitter.  If so, either change it to a wxPanel or add
1416 an EVT_SIZE handler that calls Layout().</p>
1417 <p>Fixed deadlock problem that happened when using threads.</p>
1418 <p>Added new HTML printing classes.</p>
1419 <p>Added wxWindow.GetHandle</p>
1420 <p>Apparently wxMouseEvent.Position has been deprecated in wxWindows as
1421 it is no longer available by default.  You can use GetPositionTuple
1422 (returning a tuple with x,y) instead, or GetPosition (returning a
1423 wxPoint.)</p>
1424 <p>Added wxPostEvent function that allows events to be posted and then
1425 processed later.  This is a thread-safe way to interact with the GUI
1426 thread from other threads.</p>
1427 <p>Added Clipboard and Drag-and-Drop classes.</p>
1428 <p>Added wxFontEnumerator.</p>
1429 <p>Many updates to wxMenu, wxMenuBar.</p>
1430 <p>wxPyEvent and wxPyCommandEvent derived classes now give you the actual
1431 Python object in the event handler instead of a new shadow.</p>
1432 <p>Added a Calendar widget from Lorne White to the library.</p>
1433 <p>Made some fixes to the wxFloatbar.  It still has some troubles on
1434 wxGTK...</p>
1435 <p>Added an MVC tree control from Bryn Keller to the library.</p>

1439 <p>This is a quick bug-fix release to take care of a few nasties that
1440 crept in at the last minute before 2.1.4 was called done.  No new
1441 major features.</p>

1444 <h1><a name="what-s-new-in-2-1-4">What's new in 2.1.4</a></h1>
1445 <p>This release is NOT syncronized with a snapshot release of wxGTK or
1446 wxMSW.  For MSW this isn't much of a problem since you can get the
1447 binaries from the web site.  For other platforms you'll have to build
1448 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>)
1449 To get the same set of sources from CVS that I used, checkout using
1450 the wxPy-2-1-4 tag.</p>
1451 <p>Now back to what's new...</p>
1452 <p>Much more support for event-less callbacks and add-on modules.</p>
1453 <p>Created add-on module with wxOGL classes.</p>
1454 <p>Added wxWindow.GetChildren().  Be careful of this.  It returns a <em>copy</em>
1455 of the list of the window's children.  While you are using the list if
1456 anything changes in the real list (a child is deleted, etc.) then the
1457 list you are holding will suddenly have window references to garbage
1458 memory and your app will likely crash.  But if you are careful it works
1459 great!</p>
1460 <p>Added a bunch of new and missing methods to wxTreeCrtl.  The
1461 SortChildren method is now supported, but currently only for the
1462 default sort order.</p>
1463 <p>Added typemaps for wxSize, wxPoint, wxRealPoint, and wxRect that allow
1464 either the actual objects or Python sequence values to be used.  For
1465 example, the following are equivallent:</p>
1466 <blockquote>
1467 win = wxWindow(parent, size = wxSize(100, 100))
1468 win = wxWindow(parent, size = (100, 100))</blockquote>
1469 <p>Super-charged the wxHtml module.  You can now create your own tag
1470 handlers and also have access to the parser and cell classes.  There
1471 is a tag handler in the library at wxPython.lib.wxpTag that
1472 understands the WXP tag and is able to place wxPython windows on HTML
1473 pages.  See the demo for an example.</p>
1474 <p>A bunch of the methods of wxMenuBar were previously ifdef'd out for
1475 wxGTK.  Added them back in since the methods exist now.</p>
1476 <p>Wrapped the wxHtmlHelpController and related classes.</p>
1477 <p>Wrapped the C++ versions of wxSizer and friends.  The Python-only
1478 versions are still in the library, but deprecated.  (You will get a
1479 warning message if you try to use them, but the warning can be
1480 disabled.) The usage of the C++ versions is slightly different, and
1481 the functionality of wxBorderSizer is now part of wxBoxSizer.  I have
1482 added a few methods to wxSizer to try and make the transition as
1483 smooth as possible, I combined all Add methods into a single method
1484 that handles all cases, added an AddMany method, etc.  One step I did
1485 not take was to make the default value of flag in the Add method be
1486 wxGROW.  This would have made it more backward compatible, but less
1487 portable to and from wxWin C++ code.  Please see the docs and demo for
1488 further details.</p>
1489 <p>Added wxPyEvent and wxPyCommandEvent classes, derived from wxEvent and
1490 wxCommandEvent.  Each of them has SetPyData and GetPyData methods that
1491 accept or return a single Python object.  You can use these classes
1492 directly or derive from them to create your own types of event objects
1493 that can pass through the wxWindows event system without loosing their
1494 Python parts (as long as they are stored with SetPyData.)  Stay tuned
1495 for more info and examples in future releases.</p>
1496 <p>Added wxPython.lib.grids as an example of how to derive a new sizer
1497 from the C++ sizers.  In this module you will find wxGridSizer and
1498 wxFlexGridSizer.  wxGridSizer arrainges its items in a grid in which
1499 all the widths and heights are the same.  wxFlexgridSizer allows
1500 different widths and heights, and you can also specify rows and/or
1501 columns that are growable.  See the demo for a couple examples for how
1502 to use them.</p>
1503 <p>Added the wxValidator class, and created a class named wxPyValidator
1504 that should be used for the base class of any Python validators.  See
1505 the demo for an example.  Please note that you MUST implement a Clone
1506 method in your validator classes because of the way some things work
1507 in the underlying C++ library.  I did not add wxTextValidator because
1508 of some issues of how it transfers data to and from a wxString, which
1509 in wxPython is automatically translated to and from Python strings, so
1510 there would never be a concrete wxString that would hang around long
1511 enough for the validator to do its job.  On the other hand, it should
1512 be real easy to duplicate the functionality of wxTextValidator in a
1513 pure Python class derived from wxPyValidator.</p>
1514 <p>I've finally added a feature that has been on my list for close to two
1515 years!  Ever wondered what that zero is for when you create your app
1516 object?  Well now you can leave it out or explicitly set it to a true
1517 value.  This value now controls what is to be done with sys.stdout and
1518 sys.stderr.  A false value leaves them alone, and a true value sets
1519 them to an instance of wxPyOnDemandOutputWindow.  (On windows the
1520 default is true, on unix platforms the default is false.)  This class
1521 creates a frame containing a wxTextCtrl as soon as anything is written
1522 to sys.stdout or sys.stderr.  If you close the window it will come
1523 back again the next time something is written.  (You can call
1524 app.RestoreStdio to turn this off.)  If you would rather that the stdio be
1525 redirected to a file, you can provide a second parameter to your app
1526 object's constructor that is a filename.  If you want to use your own
1527 class instead of wxPyOnDemandOutputWindow you can either implement
1528 RedirectStdio() in you app class or change the value of
1529 wxApp.outputWindowClass like this:</p>
1530 <blockquote>
1531 <dl>
1532 <dt>class MyApp(wxApp):</dt>
1533 <dd><p class="first">outputWindowClass = MyClass</p>
1534 <dl class="last">
1535 <dt>def OnInit(self):</dt>
1536 <dd>frame = MyFrame()
1537 self.SetTopWindow(frame)
1538 return true</dd>
1539 </dl>
1540 </dd>
1541 </dl>
1542 </blockquote>
1543 <p>Please see the implementation of wxPyOnDemandOutputWindow and wxApp in
1544 wx.py for more details.  A few words of caution:  if you are running
1545 your app in a debugger, changing sys.stdout and sys.stderr is likely
1546 to really screw things up.</p>
1547 <p>Added wxCaret.  Unfortunately it's author has still not documented it
1548 in the wxWindows docs...</p>
1549 <p>Some new 3rd party contributions in wxPython.lib.  PyShell, in
1550 shell.py is an interesting implementaion of an interactive Python
1551 shell in wxWindows.  floatbar.py has a class derived from wxToolBar
1552 that can sense mouse drags and then reparent itself into another
1553 frame. Moving the new frame close to where it came from puts the tool
1554 bar back into the original parent.  (Unfortunately there is currently
1555 a bug in wxGTK's wxFrame.SetToolBar so the FloatBar has some
1556 problems...)</p>

1575 <li><p class="first">There is now an an equivalence between Python's None and C++'s
1576 NULL.  This means that any methods that might return NULL will
1577 now return None and you can use none where wxWindows might be
1578 expecting NULL.  This makes things much more snake-ish.</p>

1582 <p>There is a new build system based on a new Python program instead of
1583 raw makefiles.  Now wxPython builds are virtually the same on MSW or
1584 Unix systems.  See the end of this file for new build instructions and
1585 see distrib/build.py for more details.</p>
1586 <p>wxDC.Bilt now includes the useMask parameter, and has been split into
1587 two different versions.  wxDC.BlitXY is like what was there before and
1588 takes raw coordinants and sizes, and the new wxDC.Blit is for the new
1589 interface using wxPoints and a wxSize.</p>

1592 <h1><a name="what-s-new-in-2-1b2">What's new in 2.1b2</a></h1>
1593 <p>Added the missing wxWindow.GetUpdateRegion() method.</p>
1594 <p>Made a new change in SWIG (update your patches everybody) that
1595 provides a fix for global shadow objects that get an exception in
1596 their __del__ when their extension module has already been deleted.
1597 It was only a 1 line change in .../SWIG/Modules/pycpp.cxx at about
1598 line 496 if you want to do it by hand.</p>
1599 <p>It is now possible to run through MainLoop more than once in any one
1600 process.  The cleanup that used to happen as MainLoop completed (and
1601 prevented it from running again) has been delayed until the wxc module
1602 is being unloaded by Python.</p>
1603 <p>I fixed a bunch of stuff in the C++ version of wxGrid so it wouldn't
1604 make wxPython look bad.</p>
1605 <p>wxWindow.PopupMenu() now takes a wxPoint instead of  x,y.  Added
1606 wxWindow.PopupMenuXY to be consistent with some other methods.</p>
1607 <p>Added wxGrid.SetEditInPlace and wxGrid.GetEditInPlace.</p>
1608 <p>You can now provide your own app.MainLoop method.  See
1609 wxPython/demo/demoMainLoop.py for an example and some explaination.</p>
1610 <p>Got the in-place-edit for the wxTreeCtrl fixed and added some demo
1611 code to show how to use it.</p>
1612 <p>Put the wxIcon constructor back in for GTK as it now has one that
1613 matches MSW's.</p>
1614 <p>Added wxGrid.GetCells</p>
1615 <p>Added wxSystemSettings static methods as functions with names like
1616 wxSystemSettings_GetSystemColour.</p>
1617 <p>Removed wxPyMenu since using menu callbacks have been deprecated in
1618 wxWindows.  Use wxMenu and events instead.</p>
1619 <dl>
1620 <dt>Added alternate wxBitmap constructor (for MSW only) as</dt>
1621 <dd>wxBitmapFromData(data, type, width, height, depth = 1)</dd>
1622 </dl>
1623 <p>Added a helper function named wxPyTypeCast that can convert shadow
1624 objects of one type into shadow objects of another type.  (Like doing
1625 a down-cast.)  See the implementation in wx.py for some docs.</p>
1626 <p>Fixed wxImage GetData and SetData to properly use String objects for
1627 data transfer.</p>
1628 <p>Added access methods to wxGridEvent.</p>
1629 <p>New Makefile/Setup files supporting multiple dynamic extension modules
1630 for unix systems.</p>
1631 <p>Fixes for the wxGLCanvas demo to work around a strange bug in gtk.</p>
1632 <p>SWIG support routines now compiled separately instead of being bundled
1633 in wx.cpp.</p>

1637 <p>Fixed wxComboBox.SetSelection so that it actually sets the selected
1638 item.  (Actually just removed it from wxPython and let it default to
1639 wxChoice.SetSelection which was already doing the right thing.)</p>
1640 <p>Added the Printing Framework.</p>
1641 <p>Switched back to using the wxWindows DLL for the pre-built Win32
1642 version.  The problem was needing to reinitialize static class info
1643 data after loading each extension module.</p>
1644 <p>Lots of little tweaks and additions to reflect changes to various
1645 wxWindows classes.</p>
1646 <p>Fixed a bug with attaching objects to tree items.  Actually was a
1647 symptom of a larger problem with not obtaining the interpreter lock
1648 when doing any Py_DECREFs.</p>
1649 <p>wxSizer and friends.  Sizers are layout tools that manage a colection
1650 of windows and sizers.  Different types of sizers apply different
1651 types of layout algorithms.  You saw it here first!  These classes are
1652 not even in the wxWindows C++ library yet!</p>

1657 <p>Bug fix for occassional GPF on Win32 systems upon termination of a
1658 wxPython application.</p>
1659 <p>Added wxListBox.GetSelections returning selections as a Tuple.</p>
1660 <p>Added a wxTreeItemData that is able to hold any Python object and be
1661 associated with items in a wxTreeCtrl.  Added test pytree.py to show
1662 this feature off.</p>
1663 <p>Added wxSafeYield function.</p>
1664 <p>OpenGL Canvas can be optionally compiled in to wxPython.</p>
1665 <p>Awesome new Demo Framework for showing off wxPython and for learning
1666 how it all works.</p>
1667 <p>The pre-built Win32 version is no longer distributing the wxWindows
1668 DLL.  It is statically linked with the wxWindows library instead.</p>
1669 <p>Added a couple missing items from the docs.</p>
1670 <p>Added wxImage, wxImageHandler, wxPNGHandler, wxJPEGHandler,
1671 wxGIFHandler and wxBMPHandler.</p>
1672 <p>Added new methods to wxTextCtrl.</p>

1694 <p>Well obviously the numbering scheme has changed.  I did this to
1695 reflect the fact that this truly is the second major revision of
1696 wxPython, (well the third actually if you count the one I did for
1697 wxWindows 1.68 and then threw away...) and also that it is associated
1698 with the 2.0 version of wxWindows.</p>
1699 <p>I have finally started documenting wxPython.  There are several pages
1700 in the wxWindows documentation tree specifically about wxPython, and I
1701 have added notes within the class references about where and how wxPython
1702 diverges from wxWindows.</p>
1703 <p>Added wxWindow_FromHWND(hWnd) for wxMSW to construct a wxWindow from a
1704 window handle.  If you can get the window handle into the python code,
1705 it should just work...  More news on this later.</p>
1706 <p>Added wxImageList, wxToolTip.</p>
1707 <p>Re-enabled wxConfig.DeleteAll() since it is reportedly fixed for the
1708 wxRegConfig class.</p>

1720 <tt class="literal"><span class="pre">&quot;from</span> <span class="pre">wxPython.wx</span> <span class="pre">import</span> <span class="pre">*&quot;</span></tt>  This is for people who are worried about
1721 namespace pollution, they can use &quot;from wxPython import wx&quot; and then
1722 prefix all the wxPython identifiers with &quot;wx.&quot;</p>
1723 <p>Added wxTaskbarIcon for wxMSW.</p>
1724 <p>Made the events work for wxGrid.</p>
1725 <p>Added wxConfig.</p>
1726 <p>Added wxMiniFrame for wxGTK.</p>
1727 <p>Changed many of the args and return values that were pointers to gdi
1728 objects to references to reflect changes in the wxWindows API.</p>

1733 <p>wxPython on wxGTK works!!!  Both dynamic and static on Linux and
1734 static on Solaris have been tested.  Many thanks go to Harm
1735 &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
1736 down a nasty DECREF bug.  Okay so I have to confess that it was just a
1737 DSM (Dumb Stupid Mistake) on my part but it was nasty none the less
1738 because the behavior was so different on different platforms.</p>
1739 <p>The dynamicly loaded module on Solaris is still segfaulting, so it
1740 must have been a different issue all along...</p>

1744 <p>1. Worked on wxGTK compatibility.  It is partially working.  On a
1745 Solaris/Sparc box wxPython is working but only when it is statically
1746 linked with the Python interpreter.  When built as a dyamically loaded
1747 extension module, things start acting weirdly and it soon seg-faults.
1748 And on Linux both the statically linked and the dynamically linked
1749 version segfault shortly after starting up.</p>
