<h1 class="title">Recent Changes for wxPython</h1>
<div class="section">
<h1><a id="id1" name="id1">2.7.1.2</a></h1>
<ul class="simple">
<li>21-Oct-2006</li>
</ul>
<p>Fixed a bug in the MaskedEdit controls caused by conflicting IsEmpty
methods.</p>
<p>Patch #1579280: Some mimetype optimizations on unix-like systems.</p>
<p>wxMac: Several wx.webkit.WebKitCtrl enhancements/fixes, including:</p>
<blockquote>
<ul class="simple">
<li>new methods for increasing/decreasing text size, getting
selection, getting/setting scroll position, printing, enabling
editing, and running JavaScripts on the page.</li>
<li>added new event (wx.webkit.WebKitBeforeLoadEvent) for catching, and
possibly vetoing, load events before they occur.</li>
<li>wx.webkit.WebKitCtrl now fires mouse events for certain events
that it was eating before. This improves wxSplitterWindow
resizing behavior.</li>
<li>refactoring of the sizing logic to move the Cocoa view.  Tested
with splitter windows, panels, notebooks and all position
correctly with this.</li>
</ul>
</blockquote>
<p>Some improvements to the drawing code in CustomTreeCtrl.</p>
<p>Fixed refcount leak in wx.Window.GetChildren.</p>
</div>
<div class="section">
<h1><a id="id2" name="id2">2.7.1.1</a></h1>
<ul class="simple">
<li>18-Oct-2006</li>
</ul>
<p>The following deprecated items have been removed:</p>
<blockquote>
<ul class="simple">
<li>wx.Bitmap SetQuality and GetQuality methods</li>
<li>The wx.GetNumberFromUser function</li>
<li>wx.EVT_LIST_GET_INFO and wx.EVT_LIST_SET_INFO</li>
<li>wx.BookCtrlSizer and wx.NotebookSizer</li>
<li>The PostScript-specific methods of wx.PrintData</li>
<li>wx.PrintDialogData SetSetupDialog and GetSetupDialog methods</li>
<li>wx.FontMapper SetConfig method</li>
<li>wx.html.HtmlSearchStatus.GetContentsItem method</li>
<li>wx.html.HtmlHelpData.GetContents, GetContentsCnt, GetIndex, and
GetIndexCnt methods</li>
</ul>
</blockquote>
<p>wx.EventLoop is now implemented for wxMac.</p>
<p>Added wxPython wrappers for the new wx.Treebook and wx.Toolbook
classes.</p>
<p>wx.DC.BeginDrawing and EndDrawing have been deprecated in the C++
code, so since they never really did anything before they are now just
empty stubs in wxPython.</p>
<p>Solved a problem that has been around for a very long time in how C++
methods are virtualized for overriding in derived Python classes.
Previously we couldn't do it for methods that needed to also exist in
the base class wrappers such that they could be called normally.  (The
reasons are long and complex, but suffice it to say that it was due to
mixing C++'s dynamic dispatch, and Python's runtime lookup of the
method attributes resulting in endless recursion of function calls.)
Because of this problem I used a hack that I have always hated, and
that is renaming the base class methods with a &quot;base_*&quot; prefix, for
example wx.Printout.base_OnBeginDocument.  Now that the problem has
finally been solved I have replaced all the base_Whatever() methods
with the real Whatever() method as well as a simple wrapper named
base_Whatever that is marked as deprecated.  So now instead of writing
your overridden methods like this:</p>
<pre class="literal-block">
def OnBeginDocument(self, start, end):
    # do something here
    return self.base_OnBeginDocument(start, end)
</pre>
<p>You can now call the base class method the normal way, like this:</p>
<pre class="literal-block">
def OnBeginDocument(self, start, end):
    # do something here
    return Printout.OnBeginDocument(self, start, end)
</pre>
<p>Or like this with super():</p>
<pre class="literal-block">
def OnBeginDocument(self, start, end):
    # do something here
    return super(MyPrintout, self).OnBeginDocument(start, end)
</pre>
<p>Note that the old way with the &quot;base_*&quot; function still works, but you
will get a DeprecationWarning from calling base_OnBeginDocument.  The
classes affected by this are:</p>
<blockquote>
<ul class="simple">
<li>wx.DropSource</li>
<li>wx.DropTarget</li>
<li>wx.TextDropTarget</li>
<li>wx.FileDropTarget</li>
<li>wx.PyLog   (also added the ability to override Flush)</li>
<li>wx.PyApp   (also added the ability to override ExitMainLoop)</li>
<li>wx.Printout</li>
<li>wx.PyPrintPreview</li>
<li>wx.PyPreviewFrame</li>
<li>wx.PreviewControlBar</li>
<li>wx.Process</li>
<li>wx.PyControl</li>
<li>wx.PyPanel</li>
<li>wx.PyScrolledWindow</li>
<li>wx.PyWindow</li>
<li>wx.Timer</li>
<li>wx.grid.PyGridCellRenderer</li>
<li>wx.grid.PyGridCellEditor</li>
<li>wx.grid.PyGridCellAttrProvider</li>
<li>wx.grid.PyGridTableBase</li>
<li>wx.html.HtmlWindow</li>
<li>wx.wizard.PyWizardPage</li>
</ul>
</blockquote>
<p>Added the wx.DC.GradientFillConcentric and wx.DC.GradientFillLinear
methods.</p>
<p>wxGTK: wx.ListBox and wx.CheckListBox are now using native GTK2
widgets.</p>
<p>Added wx.ListBox.HitTest() from patch 1446207</p>
<p>Bumped up to SWIG 1.3.29.  This provides some more runtime performance
boosts, gets rid of the dreaded Ptr classes, and some other nice new
things.</p>
<p>Added wx.Window.GetScreenPosition and GetScreenRect which returns the
position of the window in screen coordinates, even if the window is
not a top-level window.</p>
<p>Added GetResourcesDir and GetLocalizedResourcesDir to
wx.StandardPaths.</p>
<p>Added a GetReceivedFormat method to wx.DataObjectComposite.  You can
use this to find out what format of data object was recieved from the
source of the clipboard or DnD operation, and then you'll know which
of the component data objects to use to access the data.</p>
<p>Changed how the stock objects (wx.RED, wx.RED_PEN, wx.RED_BRUSH, etc.)
are initialized.  They are now created as uninitialized instances
using __new__.  Then after the wx.App has been created, but before
OnInit is called, the .this attribute of each object is initialized.
This was needed because of some delayed initialization functionality
that was implemented in wxWidgets, but the end result is cleaner for
wxPython as well, and allowed me to remove some ugly code previously
hidden under the covers.</p>
<p>Added wx.StandardPaths.GetDocumentsDir.</p>
<p>Added wx.RendererNative.DrawCheckButton.</p>
<p>wx.ProgressDialog.Update now returns a tuple of two values.  The first
is a continue flag (what was returned before) and the second is a skip
flag.  If the dialog has the wx.PD_CAN_SKIP flag and if the Skip
button is clicked, then the skip flag is set to True the next time
Update is called.</p>
<p>A DeprecationWarning is now issued when the old wxPython package is
imported.  If you are still using the old namespace please convert
your code to use the new wx package instead.</p>
<p>Added wrappers for Julian's new wxRichTextCtrl class, visible in
wxPython as wx.richtext.RichTextCtrl window.  It still needs some more
work, but it is a great start.</p>
<p>wx.lib.mixins.listctrl.TextEditMixin: Fixed the double END_LABEL_EDIT
event problem in TextEditMixin by checking if the editor was already
hidden before continuing with the CloseEditor method.  Also added code
to OpenEditor to send the BEGIN_LABEL_EDIT event and to not allow the
opening of the editor to continue if the event handler doesn't allow
it.</p>
<p>wx.StaticBoxSizer now keeps better track of the wx.StaticBox, and it
will destroy it if the sizer is destroyed before the parent window is.</p>
<p>Added wx.HyperlinkCtrl.</p>
<p>Added battery and power related functions and events (wxMSW only so
far.)  See wx.PowerEvent, wx.GetPowerType and wx.GetBatteryState.</p>
<p>Added wx.ListCtrl.HitTestSubItem which returns the sub-item (i.e. the
column in report mode) that was hit (if any) in addition to the item
and flags.</p>
<p>Added wrappers for wx.ColourPickerCtrl, wx.DirPickerCtrl,
wx.FilePickerCtrl, and wx.FontPickerCtrl.</p>
<p>Patch #1502016 wx.Image.ConvertToGreyscale now retains the alpha
channel.</p>
<p>Added wrappers for the wxAUI classes, in the wx.aui module.</p>
<p>Added the PseudoDC class from Paul Lanier.  It provides a way to
record operations on a DC and then play them back later.</p>
<p>Upgraded to Scintilla 1.70 for wx.stc.StyledTextCtrl.</p>
<p>Added CanSetTransparent and SetTransparent methods to the
wx.TopLevelWindow class, with implementations (so far) for wxMSW and
wxMac.</p>
<p>SetDefaultItem() and GetDefaultItem() are now members of
wx.TopLevelWindow, not wx.Panel.</p>
<p>wxGTK: Stock items (icons) will be used for menu items with stock
IDs.</p>
<p>Added wx.lib.combotreebox from Frank Niessink</p>
<p>Added wx.ImageFromBuffer, wx.BitmapFromBuffer and
wx.BitmapFromBufferRGBA factory functions.  They enable loading of an
image or bitmap directly from a Python object that implements the
buffer interface, such as strings, arrays, etc.</p>
<p>Added wx.App.IsDisplayAvailable() which can be used to determine if a
GUI can be created in the current environment.  (Still need an
implementation for wxMSW...)</p>
<p>The wx.html.HTML_FONT_SIZE_x constants are no longer available as the
default sizes are now calculated at runtime based on the size of the
normal GUI font.</p>
<p>wx.Colour now includes an alpha component, which defaults to
wx.ALPHA_OPAQUE.  This is in preparation for allowing various new
alpha blening functionality using wx.Colour objects, such as drawing
with pens and brushes on a wx.DC.</p>
<p>Added wx.NativePixelBuffer, wx.AlphPixelBuffer and related iterator
and accessor classes.  They allow platform independent direct access
to the platform specific pixel buffer inside of a wx.Bitmap object.</p>
<p>The beginnings of support for RTL languages has been added, thanks to
a Google SoC project.</p>
<p>Added wx.lib.dragscroller from Riaan Booysen.  It provides a helper
class that can used to scroll a wx.ScrolledWindow in response to a
mouse drag.</p>
<p>Applied patch 1551409: Adds support for indeterminate mode gauges.</p>
<p>wxMac: I've turned on the compile option for using the native toolbar
on the Mac now that it supports hosting of controls.  If the toolbar
is managed by the frame via either CreateToolBar() or SetToolBar()
then the native toolbar will be used.  Additional toolbars, or
toolbars that are not children of the frame, are managed by sizers or
what-not will still use the emulated toolbar because of platform
restrictions in how/where the native toolbar can be used.</p>
<p>Added Python properties for many of the getter/setter methods of wx
classes.  In order for the names to be predicatble for somebody
already familiar with wxPython the property names are simply the name
of the getter with the &quot;Get&quot; dropped.  For example, wx.Window has a
property named &quot;Size&quot; that maps to GetSize and SetSize.  So far there
is only one known name conflict using this naming convention, and that
is wx.KeyEvent.KeyCode, however since KeyCode was formerly a
compatibility alias for GetKeyCode (and has been for a long time) it
was decided to just switch it to a property.  If you want to use the
method then change your calls to event.KeyCode() to
event.GetKeyCode(), otherwise you can use it as a property just by
dropping the parentheses.</p>
<p>Updated the C++ code for wx.gizmos.TreeListCtrl from the wxCode
project.  This has resulted in some minor API changes, most of which
were worked around in the wrapper code.</p>
<p>Added wx.lib.delayedresult from Oliver Schoenborn.</p>
<p>Added wx.lib.expando, a multi-line textctrl that exands as more lines
are needed.</p>
<p>wx.Image.Scale and Rescale methods now take an extra parameter
specifying type of method to use for resampling the image.  It
defaults to the current behavior of just replicating pixels, if
wx.IMAGE_QUALITY_HIGH is passed then it uses bicubic and box averaging
resampling methods for upsampling and downsampling respectively.</p>
<p>Added the wx.lib.buttonpanel module, which is a tweaked version of
Andrea Gavana's FancyButtonPanel module.</p>
<p>Added the wx.lib.flatnotebook module, from Andrea Gavana.</p>
<p>Renamed wx.FutureCall to wx.CallLater so it is named more like
wx.CallAfter.  wx.FutureCall is now an empty subclass of wx.CallLater
for compatibility of older code.</p>
<p>Added the wx.lib.customtreectrl module from Andrea Gavana.</p>
<p>Added ChangeSelection to wx.BookCtrl (the base class for wx.Notebook
and other book controls) that is the same as SetSelection but doesn't
send the change events.</p>
<p>Added wx.TextCtrl.ChangeValue() which is the same as SetValue() but
doesn't send the text changed event.</p>
<p>For consistency, all classes having an Ok() method now also have
IsOk(), use of the latter form is preferred although the former hasn't
been deprecated yet</p>
<p>Added the wx.AboutBox() function and wx.AboutDialogInfo class.  They
provide a way to show a standard About box for the application, which
will either be a native dialog or a generic one depending on what info
is provided and if it can all be shown with the native dialog.</p>
<p>The code in the animate contrib has been moved into the code wxWidgets
library, and refactored a bit along the way.  For wxPython it still
exists in the wx.animate module, but has basically been reduced to two
classes, wx.animate.Animation, and wx.animate.AnimationCtrl.  You load
the animated GIF (and hopefully there will be other supported formats
in the near future) in the Animation object, and then give that to the
AnimatedCtrl for display.  See the demo for an example.  There is also
still a GIFAnimationCtrl class that provides some level of backwards
compatibility with the old implementation.</p>
<p>wxMac: The compile option that turns on the use of CoreGraphics (a.k.a
Quartz) for wxDC is now turned on by default.  This means that all
drawing via wxDC is done using the new APIs from apple, instead of the
old Quick Draw API.  There are, however, a few places where Quartz and
wxDC don't fit together very well, mainly the lack of support for
logical drawing operations such as XOR, but there is work in progress
to provide other ways to do the same sort of thing that will work with
Quartz and also on the other platforms.</p>
<p>The first parts of a new 2D drawing API has been added with the
wx.GraphicsPath and wx.GraphicsContext classes.  They wrap GDI+ on
Windows, Cairo on wxGTK and CoreGraphics on OS X.  They allow path-based
drawing with alpha-blending and anti-aliasing, and use a floating
point cooridnate system.  Currently they can only target drawing to
windows, but other wx.DC backends are forthcoming.  The APIs may
evolve a bit more before they are finalaized with the 2.8 release, but
there is enough there now to get a good feel for how things will work.
There is also a transitional wx.GCDC class that provides the wx.DC API
on top of wx.GraphicsContext.  Docs and a demo are still MIA.</p>
<p>Added a wx.AutoBufferedPaintDC that is a subclass of wx.PaintDC on
platforms that do double buffering by default, and a subclass of
wx.BufferedPaintDC on the platforms that don't.  You can use this
class to help avoid the overhead of buffering when it is not
needed. There is also a wx.AutoBufferedPaintDCFactory function that
does a little more and actually tests if the window has
double-buffering enabled and then decides whether to return a
wx.PaintDC or wx.BufferedPaintDC.  This uses the new
wx.Window.IsDoubleBuffered method.</p>

<h1><a id="id3" name="id3">2.6.3.3</a></h1>
<ul class="simple">

<dl class="docutils">
<dt>wx.lib.pubsub updates from Oliver Schoenborn:</dt>
<dd><ul class="first last simple">
<li>fixed the hash problem with non-hashable objects</li>
<li>now supports listeners that use *args as an argument
(listener(*args) was not passing the validity test)</li>
<li>corrected some mistakes in documentation</li>
<li>added some clarifications (hopefully useful for first time
users)</li>
<li>changed the way singleton is implemented since old way prevented
pydoc etc from extracting docs for Publisher</li>
</ul>
</dd>
<dt>DocView and ActiveGrid IDE updates from Morgan Hua:</dt>
<dd>New Features: In Tab-View mode, Ctrl-number will take the user to
the numbered tab view.  Modified files now show an '*' astrisk in
the view title.  Debugger framework can now support PHP debugging.
Not important for python development, but at least that means the
debugger framework is more generalized.</dd>
</dl>
<p>wx.lib.mixins.listctrl.TextEditMixin: Fixed the double END_LABEL_EDIT
event problem in TextEditMixin by checking if the editor was already
hidden before continuing with the CloseEditor method.  Also added code
to OpenEditor to send the BEGIN_LABEL_EDIT event and to not allow the
opening of the editor to continue if the event handler doesn't allow
it.</p>
<p>Undeprecated wx.GetNumberFromUser and added wx.NumberEntryDialog.</p>
<p>Made necessaary changes for building wxPython for Python 2.5.  There
may still be some issues related to the new Py_ssize_t type and 64-bit
machines, but at least all compile errors and warnings related to it
have been resolved.</p>
</div>
<div class="section">
<h1><a id="id4" name="id4">2.6.3.2</a></h1>
<ul class="simple">
<li>3-April-2006</li>
</ul>
<p>Fixed reference leak in wx.gizmos.TreeListCtrl.GetSelections.</p>
<p>wxMSW: Fixed sizing issue with wx.Choice and wx.ComboBox.  This change
was implemented by reverting a prior fix for a different problem
(contiuous painting/resizing when a combobox is used as a widget in a
wx.html.HtmlWindow) so a method to fix both problems is still being
investigated.</p>
<p>wxGTK: Fixed potential buffer overrun when pasting from the
clipboard.</p>
<p>Fixed problem in wx.lib.splitter when used on 64-bit platforms.  Used
the current length of the list for specifying an append instead of
sys.maxint.</p>
<p>wxMSW: Support added for XP themed owner drawn buttons and bitmap
buttons.  For example, if you change the foreground color of a button
it will now be drawn with the XP themed style rather than an ugly
generic button style.</p>
<p>XRCed: Fix for Copy/Paste objects with international characters.</p>
<p>Fixed the equality and inequality operators for some of the basic
data types (wx.Point, wx.Size, wx.Colour, etc.) to no longer raise a
TypeError if the compared object is not compatible, but to just return
a boolean as expected.  For example:</p>
<pre class="literal-block">
wx.Colour(64,0,64) == 123      ==&gt; False
</pre>
<p>wxMSW: Fixed (again) sizing/positioning issues of calling Realize on
a wx.ToolBar that is not manaaged directly by a frame and that is
already shown.</p>
<p>wxMSW: Fixed wx.Choice/wx.ComboBox so they send events when a new item
is selected only with the keyboard.</p>
</div>
<div class="section">
<h1><a id="id5" name="id5">2.6.3.0</a></h1>
<ul class="simple">
<li>27-March-2006</li>
</ul>
<p>Change the wx.ListCtrl InsertStringItem wrapper to use the form that
takes an imageIndex, and set the default to -1.  This ensures that on
wxMSW that if there is an image list but they don't specify an image,
the native control doesn't use one anyway.</p>
<p>wxMSW: wx.ListCtrl in report mode is now able to support images in
other columns besides the first one.  Simply pass an image index to
SetStringItem.  For virtual list controls you can specify the image to
use on the extra columns by overriding OnGetItemColumnImage in your
derived class.  It is passed the item number and the column number as
parameters, and the default version simply calls OnGetItemImage for
column zero, or returns -1 for other columns.</p>
<p>Switched to using SWIG 1.3.27 for generating the wrapper code.  There
are some small changes needed to SWIG to work around some bugs that
wxPython exposes, and to be able to generate code that matches that
which wxPython is using.  If you are building wxPython yourself and
need to modify any of the *.i files or to add your own, then you will
want to be sure to use a matching SWIG.  See wxPython/SWIG/README.txt
in the source tarball for details.</p>
<p>wx.Image.Copy, Mirror, and GetSubImage now also do the right thing
with  the alpha channel.</p>
<p>wxMSW: Fixed problem in wx.TextCtrl where using SetValue and
wx.TE_RICH2 would cause the control to be shown if it was hidden.</p>
<p>wxMSW: Numpad special keys are now distinguished from normal keys in
key events.</p>
<p>wxMSW: Multiline notebook tab label change now resizes the control
correctly if an extra row is removed or added.</p>
<p>wxMSW: On XP fall back to unthemed wxNotebook if specified orientation
not available in the themed version.</p>
<p>Added wx.Toolbar.GetToolsCount.</p>
<p>Added wx.GridSizer.CalcRowsCols.</p>
<p>Added wx.OutputStream.LastWrite.</p>
<p>wxGTK: EVT_SET_CURSOR is now sent.</p>
<p>wxGTK: Fix RequestMore for idle events.</p>
<p>wxGTK: Implement user dashes for PS and GNOME printing.</p>
<p>wxGTK: Correct update region code. Don't always invalidate the whole
window upon resize. Reenable support for thewx.NO_FULL_REPAINT_ON_RESIZE
flag.  Also disable refreshing custom controls when focusing in and out.</p>
<p>wx.lib.pubsub: Publisher is now able to parse a dotted notation string
into a topic tuple.  For example: subscribing to &quot;timer.clock.seconds&quot;
is the same as subscribing to (&quot;timer&quot;, &quot;clock&quot;, &quot;seconds&quot;).</p>
<p>Applied patch #1441370: lib.plot - allow passing in wx.Colour()</p>
<p>Added wx.CommandEvent.GetClientData.</p>
<p>Updated wxStyledTextCtrl to use version 1.67 of Scintilla.
NOTE: The STC_LEX_ASP and STC_LEX_PHP lexers have been deprecated,
you should use STC_LEX_HTML instead.</p>
<p>wxSTC: Implemented Fix for SF Bug #1436503.  Delay the start of the
DnD operation in case the user just intended to click, not drag.</p>
<p>Updated the analogclock.py module to the new analogclock package from
E. A. Tacao.</p>
<p>Added the wx.lib.mixins.listctrl.CheckListCtrlMixin class from Bruce
Who, which makes it easy to put checkboxes on list control items.</p>
<p>Applied a patch from Christian Kristukat to wx.lib.plot that adds
scrollbars when the plot is zoomed in, and also the ability to grab a
zoomed plot and move it around with a mouse drag.</p>
<p>XRCed updated to allow wxMenuBar to be created inside a wxFrame.</p>
<p>Added wx.StandardPaths.GetDocumentsDir() (patch 1214360)</p>

<p>wxMSW: Fix for bug #1211907, popup menu indenting inconsistent with
bitmaps.</p>
<p>wxMac: Don't send an event for wx.RadioButton deselections, just the

platforms.</p>
<p>wxMSW: Always set flat toolbar style, even under XP with themes: this

<p>Fixes for bug #1217872, pydocview.DocService not correctly initialized.</p>
<p>Fix for bug #1217874, Error in parameter name in DocManager.CreateView.</p>
<p>Added wrappers for the wx.RendererNative class.</p>
<p>Added the wx.lib.splitter module, which contains the
MultiSplitterWindow class.  This class is much like the standard
wx.SplitterWindow class, except it allows more than one split, so it
can manage more than two child windows.</p>
<p>Docview and IDE patch from Morgan Hua with fix for bug #1217890
&quot;Closing view crashes Python&quot; plus some new features:</p>
<blockquote>
New feature added to the IDE is 'Extensions'.  Under
Tools|Options|Extensions, you can add calls to external programs.
For example you can add a &quot;Notepad&quot; extension (under windows) that
will exec Notepad on the currently open file.  A new &quot;Notepad&quot;
menu item will appear under the Tools menu.</blockquote>
<p>Some fixes to XRCed to make encoding errors a bit more user friendly.</p>
<p>XRCed changes from Roman Rolinsky:</p>
<blockquote>
<ul class="simple">
<li>Added new controls (Choicebook, Listbook, StatusBar,
DatePicker), and completed style flags. Test window is opened
for an available parent control if no specific view
defined. Better handling of exceptions (highlighting does not
'stick' anymore).</li>
<li>Use system clipboard for Copy/Paste.</li>
<li>Improved some dialogs (window styles, growable cols). Changed
the range for wxSpinCtrl min/max to all integers (default 0/100
is not always good).</li>
</ul>
</blockquote>
<p>Updates for wx.lib.foldpanelbar and wx.lib.hyperlink from Andrea
Gavana.</p>
<p>Fix for Bug #1283496: wxPython TheClipboard class causes problems for
pychecker.  Ensure the app has been created before initializing
wx.TheClipboard.</p>
<p>Fix for Bug #1352602: FileBrowseButtonWithHistory can't type in Value.</p>
<p>wxHTML: Added space after list item number.</p>
<p>wx.lib.printout:  Applied patch #1384440.</p>
<p>wxMSW:  Fix for Bug #1293225 Window_FromHWND crashes if parent is
None.</p>
<p>Fix for Bug #1261669, use a wx.TE_RICH2 style for the Process demo so
it doesn't fill up too soon.</p>
<p>Applied Patch #1354389: wxPython MenuItem SetBitmaps fix.</p>
<p>Applied Patch #1239456: wxPython wx.DataObject.GetAllFormats fix.</p>
<p>Applied Patch # #1230107 which allows image handlers to be written in
Python by deriving from wx.PyImageHandler.</p>
<p>Applied patch #1072210: generalize printout.py to allow text printing.</p>
<p>Applied patch #1243907: Give Throbber much more flexibility by
allowing the user to set the rest image, the direction, the current
index, custom sequence.  Allows user to manually step through the
sequence with Next(), Previous(), Increment(), Decrement() &amp;
SetCurrent(). Very handy if you have multiple throbbers that you want
to synchronize with a single timer.</p>
<p>Fix for bug #1336711: wx.lib.calendar.CalenDlg can yield incorrect

<p>Applied patch #1326241: Supporting &quot;setup.py install --install-headers=path&quot;</p>
<p>Applied patch from Morgan Hua to fix bug #1219423: CommandManager

instead of a separate menu item.</p>
<p>Fix for bug #1266745 and #1387725 in the wx.FindReplaceDialog on MSW.
Actually check we are using MSLU before doing the hack designed to
workaround a bug in MSLU!</p>
<p>wxMSW: wx.lib.iewin.IEHtmlWindow now properly handles tabbing, return
and other special keys properly.</p>
<p>Lots of PyCrust enhancments started by Franz Steinaeusler, Adi Sieker,
and Sebastian Haase, and which in turn were further enhanced, fixed
tweaked and finished up by me.  The changes include the following:</p>
<blockquote>
<ul class="simple">
<li>The Autocomplete and Calltip windows can now be opened manually
with Ctrl-Space and Ctrl-Shift-Space.</li>
<li>In the stand alone PyCrust app the various option settings,
window size and position, and etc. are saved and restored at the
next run.</li>
<li>Added a help dialog bound to the F1 key that shows the key
bindings.</li>
<li>Added a new text completion function that suggests words from
the history.  Bound to Shift-Return.</li>
<li>F11 will toggle the maximized state of the frame.</li>
<li>switched to Bind() from wx.EVT_*().</li>
<li>Display of line numbers can be toggled.</li>
<li>F12 toggles a &quot;free edit&quot; mode of the shell buffer.  This mode
is useful, for example, if you would like to remove some output
or errors or etc. from the buffer before doing a copy/paste.
The free edit mode is designated by the use of a red,
non-flashing caret.</li>
<li>Ctrl-Shift-F will fold/unfold (hide/show) the selected lines.</li>
<li>General code cleanup and fixes.</li>
<li>Use wx.StandardPaths to determine the location of the config
files.</li>
<li>Use wx.SP_LIVE_UPDATE on crust and filling windows.</li>
<li>Extended the saving of the config info and other new features to
the PyShell app too.  Additionally, other apps that embed a
PyCrust or a PyShell can pass their own wx.Config object and
have the Py code save/restore its settings to/from there.</li>
<li>All of the classes with config info get an opportunity to
save/load their own settings instead of putting all the
save/load code in one place that then has to reach all over the
place to do anything.</li>
<li>Enable editing of the startup python code, which will either be
the file pointed to by PYTHONSTARTUP or a file in the config dir
if PYTHONSTARTUP is not set in the environment.</li>
<li>Added an option to skip the running of the startup code when
PyShell or PyCrust starts.</li>
<li>PyCrust adds a pp(item) function to the shell's namespace that
pretty prints the item in the Display tab of the notebook.
Added code to raise that tab when pp() is called.</li>
<li>Added an option for whether to insert text for function
parameters when popping up the call tip.</li>
<li>Added Find and Find-Next functions that use the
wx.FindReplaceDialog.</li>
</ul>
</blockquote>
<p>Applied patches from Will Sadkin for wx.lib.masked modules:</p>
<blockquote>
<ul class="simple">
<li>Now ignores kill focus events when being destroyed.</li>
<li>Added missing call to set insertion point on changing fields.</li>
<li>Modified SetKeyHandler() to accept None as means of removing
one.</li>
<li>Fixed keyhandler processing for group and decimal character
changes.</li>
<li>Fixed a problem that prevented input into the integer digit of a
integerwidth=1 numctrl, if the current value was 0.</li>
<li>Fixed logic involving processing of &quot;_signOk&quot; flag, to remove
default sign key handlers if false, so that
SetAllowNegative(False) in the NumCtrl works properly.</li>
<li>Fixed selection logic for numeric controls so that if
selectOnFieldEntry is true, and the integer portion of an
integer format control is selected and the sign position is
selected, the sign keys will always result in a negative value,
rather than toggling the previous sign.</li>
</ul>
</blockquote>
<p>wx.FontMapper.SetConfig is deprecated.  You should instead just set an
application-wide config object with wx.Config.Set, which wx.FontMapper
will use by default.</p>
<p>Added wx.GetMouseState which returns the current state of the mouse.
It returns an instance of a wx.MouseState object that contains the
current position of the mouse pointer in screen coordinants, as well
as boolean values indicating the up/down status of the mouse buttons
and the modifier keys.</p>
<p>Added wx.SizerItem.SetUserData</p>
<p>A variety of updates to wx.lib.floatcanvas, including Added
DrawObjects, including a ScaledTextBox, with auto-wrapping, etc, and
Scaled and Unscaled Bitmap Objects.</p>
<blockquote>
WARNING: Changed all DrawObjects to take an (x,y) pair rather
than individual x,y parameters. Also changed rectangles and
ellipses to take (w,h) pair. This is an API change, but should
be easy to accommodate, all you need to do is add a parenthesis
pair:  (...x, y, ...) ---&gt;  (...(x,y), ...)</blockquote>

wx.STIPPLE_MASK_OPAQUE.</p>
<p>wxMSW: Fix for default control colours when the system text fg colour
is not black.</p>
<p>wxGTK: Patch #1171754, It is now possible to have a menu item that
both has an icon and is a submenu.</p>
<p>wxMSW: Patch #1197009, better refreshes when windows are moved and
resized.</p>
<p>wxMSW: Patch #1197468.  Keeps track of pending size/position changes
in case there is more than one adjustment for a window in a single
DeferWindowPos set, then the pending values can be used for defaults
instead of current values.</p>
<p>Fixed the typemap that converts a Python list of strings to a
wxArrayString so it uses the wxPython default encoding.</p>
<p>Several docstrings added and updated.  Lots more to go.</p>
<p>wxMac: Strings added to the clipboard or used in DnD no longer have an
extra null character at the end.</p>
<p>Added wx.GetXDisplay that returns a raw swigified pointer for the X11
Display, or None for the non-X11 platforms.</p>
<p>wxMenu: Don't send an event when selecting an already selected radio
item.</p>
<p>Added wx.LaunchDefaultBrowser.</p>
<p>wxMSW: Fixed erroneous selection of content in wx.ComboBox when within
a wx.StaticBox.</p>
<p>wxMSW: Fixed alpha blitting to take into account source position.</p>
<p>Ensure that Python is still in an initialized state before doing any
locking or unlocking in wxPyBeginBlockThreads and wxPyEndBlockThreads
as these can be triggered after Python has been finalized in embedding
situations.</p>
<p>Added alternate constructors for wx.Font: wx.FontFromPixelSize,
wx.FFont, wx.FFontFromPixelSize.  See the docstrings or new api docs
for details.</p>
<p>Added wx.lib.hyperlink from Andrea Gavana.  It is a control like
static text that acts like a hyper-link, launching the system's
default browser in response to the clicks.</p>
<p>Added an optional parameter to wxversion.select that allows you to
specify that the extra components specified in the version string are
required.  For example, if you ask for &quot;2.6-unicode&quot; but only the ansi
version is installed then by default the ansi version will be selected
as it considered close enough since the version numbers match.  If you
want to force the options to be required then you can just add a True
parameter, like this:</p>
<pre class="literal-block">
import wxversion
wxversion.select(&quot;2.6-unicode&quot;, True)
import wx
</pre>
<p>Tweaked wx.lib.buttons such that flat buttons (e.g. have no bevel and
a wx.BORDER_NONE style flag) paint themed backgrounds if there are
transparent areas and the parent is displaying a theme.</p>
<p>wxMSW:  Fix for wrong sash colour of wx.SplitterWindow in the silver
theme on XP.</p>
<p>Added a wx.xrc.XmlResourceHandler for the Ticker class.  See
wx/lib/ticker_xrc.py</p>
<p>wxSTC: Fixed CmdKeyAssign key bindings for Ctrl-Backspace.</p>
<p>wxMSW: Fixed a bug in wx.TextCtrl where all the lines were being used
to calculate the best size, instead of using a reasonable limit.</p>
<p>XRCed: Use wx.GetDefaultPyEncoding/wx.SetDefaultPyEncoding for
changing active encoding.  Fixed pasting siblings (Ctrl key pressed
while pasting).</p>
<p>wx.lib.filebrowsebutton: Bug fix from Chad Netzer for when
self.history is None.</p>
<p>wx.ogl: Patch from Davide Salomoni that adds an optional point
parameter to LineShape.InsertLineControlPoint allowing one to
optionally specify where the new control point has to be drawn.</p>
<p>wxMSW: setting foreground colour for wx.CheckBox now works when using
XP themes.</p>
<p>More updates to the docview library modules and sample apps from the
ActiveGrid folks.  Their sample IDE is now able to integrate with
Subversion.</p>
<p>wx.grid.Grid:  Ensure that the grid gets the focus when it is
left-clicked.  Note that if you have custom widgets that handle the
EVT_LEFT_DOWN event but do not call event.Skip() then you will
probably want to add a call to self.SetFocus in the event handler.</p>
<p>wxGTK:  Add wxSTAY_ON_TOP support [Patch 1206023]</p>
<p>wx.TreeCtrl:  wx.EVT_TREE_ITEM_MENU event made consistent on all
platforms.  The location of the click or the item is included in the
event as well.</p>
<p>wxGTK: Setting background colour of a window now only affects the
window itself, not the borders, scrollbars, etc.  (Bug #1204069)</p>
<p>Print framework:  Add more paper sizes and code to fallback to an
explicit paper size if a known paper size is not found for the
printer.</p>
<p>wxMac: Applied patch for bug #1206181 Option-key decodes are wrong,
also applied patch for bug #1205691 Modified Fn keys don't work.</p>
<p>wx.Image: Fixed to preserve alpha channel in Rotate90 method.</p>
<p>wxMSW: Fixed incorrect background colour on wx.CheckListBox.</p>
<p>wxMSW: Fixed drawing of owner drawn buttons with multiline labels</p>
<p>Removed a bunch of unnecessary files, and removed or replaced images
that we're not sure of their origin or license.</p>
<p>The default DoGetBestSize is updated to not always return the current
size if the window has no sizer, children, or minsize set.  Instead
the current size is set as the minsize.  This solves the occasional
problem where a sizer may cause a childless panel to grow but never
shrink.</p>
<p>wxMSW: When converting a wx.Icon to a bitmap check if the icon has an
alpha channel and set the bitmap to use it.</p>
<p>Fixed the wrong class name used in wx.PyScrolledWindow's call to
_setCallbackInfo.</p>
<p>wxMSW: patch #1207202, Fixes GDI leak when using stock cursors.</p>
<p>wx.calendar.CalendarCtrl: Patch #1207531, Keeps the CalendarCtrl wide
enough even when the weekday names for the locale are shorter than
usual.</p>
<p>Made GridCellNumberEditor.StartingKey also insert the typed char when
there is a range of allowed values (so a wx.SpinCtrl is used instead
of a wx.TextCtrl.)</p>

<p>wxGTK:  The configure flags for selecting GTK+ 1.2.x or 2.x has
changed slightly.  It is now --with-gtk[=VERSION] where VERSION is
either '1', '2' or 'any'.  The default is '2'.</p>
<p>wx.stc.StyledTextCtrl: Added the following methods for alternate ways
to set and fetch text from the document buffer.  They work similarly
to the existing methods of the same name, except that they don't go
through the same string/unicode &lt;--&gt; wxString conversions.  The &quot;Raw&quot;
methods will do no conversions at all and in a unicode build of
wxPython the strings will be in the utf-8 encoding and in an ansi
build no assumption is made about the encoding.  The &quot;UTF8&quot; functions
will attempt to always get/set utf-8 text, which it will always be
able to do in a unicode build, and in an ansi build it will depend on
the content of the utf-8 used being compatible with the current
encoding, (you'll get an exception otherwise.)</p>

<p>wx.grid.Grid: Fixed bug #1163384.  Moved the code that handles
activating the cell editors to a EVT_CHAR event handler.  This is done

<p>Added GetCount, GetCountRGB, and GetCountColour methods to
wx.ImageHistogram.</p>
<p>wxMSW: wx.Window.Refresh changed to explicitly refresh all children as
well as the parent.  Previously it was implicitly done because parents
did not clip their children by default.  Now that they always clip
children then Refresh needed to be fixed to do a recursive refresh.

wxFoldPanelBar classes to Python.</p>
<p>wxGTK: Applied patch #1173802, reimplementation of GtkFileChooser
wxFileDialog by Mart Raudsepp.  Note that this new file dialog is only
used on GTK2 &gt;= 2.4.  For earlier GTK2 versions and GTK1 then the
older generic file dialog is used.</p>
<p>wxMSW: fixes to static box borders calculations (finalizes patch

<p>wx.Image: Use Python's buffer interface API for all image data and
alpha Set/Get methods and the ImageFromData* constructors.  They all
still copy the buffer except for SetDataBuffer and SetAlphaBuffer, but
this gives more flexibility on where the data can come from.</p>

<p>wx.Sizer Add, Insert, and Prepend functions now return a reference to the
wx.SizerItem that was added to the sizer, and the wx.SizerItem has a
GetRect accessor to give the position of the item on the parent window.</p>
<p>Added wx.Sizer.GetItem method which returns the wx.SizerItem for the given
wx.Window, wx.Sizer or position index.</p>
<p>wxMSW: wx.RadioButtons in the same group no longer have to be
consecutive (there may be intervening controls). Without this fix, an
out-of-sync assert is generated when clicking on a radio button and
then calling GetValue().</p>

<dt>Some XRC changes:</dt>
<dd><ul class="first last simple">
<li>Added 'icon' property to wxFrame and wxDialog</li>
<li>No longer ignores menu bitmaps on non-MSW platforms</li>
<li>Notebook page bitmaps are now supported</li>
<li>added system colours and fonts support (based on patch #1038207)</li>

<p>wxMSW: fix for [ 1052989 ] TextCtrl.SetBackgroundColour(wx.NullColour)
bug.</p>
<p>Added wx.PasswordEntryDialog analagous to wx.TextEntryDialog, allows
detecting entering an empty string vs. cancel unlike the
wx.GetPasswordFromUser dialog function.</p>
<p>OGL patch from Shane Holloway:</p>
<blockquote>
<p>Two simple problems found in the new python ogl code.  First is
the patch for _canvas.py.  Essentially:</p>
<pre class="literal-block">
dx = abs(dc.LogicalToDeviceX(x - self._firstDragX))
dy = abs(dc.LogicalToDeviceY(y - self._firstDragY))
</pre>
<p>was incorrect because (x,y) and (self._firstDragX,
self._firstDragY) are both already in Logical coordinates.
Therefore the difference between the two is also in logical
coordinates, and the conversion call is an error.  This bug
surfaces when you have OGL on a scrollwin, and you are far from
the origin of the canvas.</p>
<p>The second change in _composit.py basically removes the assumption
that the child is in both self._children and self._divisions.
Causes many problems when it's not.  ;)</p>
</blockquote>
<p>Fixed GetSaveData and SetSaveData in wx.lib.multisash to not depend on
the default way that class objectss are converted to strings.</p>
<p>Fixed problem in StyledTextCtrl.Set[HV]ScrollBar that could leave the
internal scrollbar visible.</p>
<p>Added wx.StandardPaths which provides methods for determining standard
system paths for each platform.</p>
<p>wxMSW: The window background is now only erased by default if the
background colour or background mode has been changed.  This better
allows the default system themed behaviour to show through for
uncustomized windows.  Explicit support added for using the correct
theme texture for wx.Notebook pages and their children.</p>
<p>wx.Image: Added support for alpha channels in interpolated and
non-interpolated image rotation.  Added ConvertAlphaToMask helper
method for turning shades of grey into shades of alpha and a colour.</p>
<p>wxGTK2: Reimplemented DoDrawRotatedText() by way of a rotation of an
alpha blended text bitmap.  It would be better if Pango could draw
directly into an wxImage (as FreeType can,) but that is for later...</p>
<p>Added wrappers and a demo for the wx.MediaCtrl class, which can play
various forms of audio/video media using native codecs install on the
system.  So far it is only implemented for Windows and OSX.</p>
<p>wxGTK: Patch applied for Freeze()/Thaw() for wxTextCtrtl.</p>
<p>Added &quot;gravity&quot; for splitter window (patch 1046105). Gravity is a
floating-point factor between 0.0 and 1.0 which controls position of
sash while resizing the wx.SplitterWindow.  The gravity specifies
how much the left/top window will grow while resizing.</p>
<p>wxMSW: wx.Slider's C++ implementation rewritten to be more
maintainable and hopefully less buggy.  The position of the labels has
also been changed in order to better comply with Microsoft's examples
of how to use the control.</p>
<p>wxMSW:  Fix wx.TreeCtrl to end label editing if the control loses
focus (a slightly modified patch 1084592.)</p>
<p>Added wx.EXEC_NODISABLE flag for wx.Execute, which will prevent all
the app's windows being disabled while a synchronous child process is
running.</p>
<p>wxMSW: Much work to correct painting (or leaving transparent) of
control backgrounds, properly using background themes on XP, etc.</p>
<p>Fixed a circular reference problem with wx.Timer.  It will now
completely cleanup after itself when the last reference to the timer
is removed.  If you were previously using timer.Destroy() to cleanup
your timers it will no longer work.  Instead you should hold a
reference to the timer and then del the reference when you are
finished with the timer.</p>
<p>Updated to 1.3.24 of SWIG.  All of my big patches have been applied to
the main SWIG source tree, but unfortunatly there were also some bugs
added that affected the wxPython build and a few details in my
original patch were changed/removed, so we are still not free of
patches.  A new patch for SWIG is located in the wxPython/SWIG
directory of the wxPython source tree.  SWIG 1.3.24 plus this patch
should be used by anyone who is making custom modifications to
wxPython's .i files, or building their own extension modules or
etc. that need to interact with the wxPython swigged types.  For the
morbidly curious, here are a few more details:</p>
<blockquote>
<ul class="simple">
<li>Since it is now possible easily and simply share the SWIG type
tables across modules I reverted to always using the stock SWIG
runtime instead of my slightly hacked up version of it exported
via the wxPython C API.</li>
<li>The %name directive is now deprecated so I replaced most uses of
it with a custom %Rename macro that uses %rename internally.
These will evetually need to be replaced with a DocDecl macro
when docstrings are added for those items.</li>
<li>The &quot;this&quot; attribute of all SWIGged classes is no longer a
string containing a &quot;swigified pointer&quot;, but rather a custom
built-in type that holds the real C pointer to the object and
the type info.  It can be converted to a string like the old
value using str() or to the long integer value of the pointer
using long().</li>
</ul>
</blockquote>
<p>Added SetDefaultPyEncoding and GetDefaultPyEncoding functions which
will set/get the encoding used by wxPython to convert string or
unicode objects to/from wxString objects.  Previously the default
Python encoding was always used, but unless the user had tweaked their
sitecustomize.py file it is always &quot;ascii&quot;, which would result in
errors if the strings contained character codes &gt;= 128.
SetDefaultPyEncoding will now allow you to control which encoding will
be used to do those conversions.  The default encoding is set to the
value of <cite>locale.getdefaultlocale()[1]</cite> when wxPython is first
imported.  Please see <a class="reference" href="http://www.alanwood.net/demos/charsetdiffs.html">http://www.alanwood.net/demos/charsetdiffs.html</a>
for information on the differences between the common latin/roman
encodings.</p>
<p>Added wxStdDialogButtonSizer, which is a a special sizer that knows
how to order and position standard buttons in order to conform to the
current platform's standards.  You simply need to add each <cite>wx.Button</cite>
to the sizer, and be sure to create the buttons using the standard
ID's.  Then call <cite>Realize</cite> and the sizer will take care of the rest.</p>
<p>wxMSW Toolbar: pass correct tool id (and not always -1) to the
EVT_TOOL_RCLICKED handler</p>
<p>wxGTK: Applied patch for combo box SELECTED events (no longer get
lots of surplus events)</p>
<p>wxGTK: Applied patch for proper menu highlight colour detection in
wx.SystemSettings.</p>
<p>wxGTK: Commited scrollbar patch #1093339 which sends lineup, linedown
events based on intercepting the mouse down events.</p>
<p>wxGTK: Applied patch #1102789 which solved conflicts between wxWidgets
and GTK+'s context menu code.</p>
<p>wxGTK: Applied patch #1100327 for correct feedback from DND actions
(not all actions are allowed).</p>
<p>Fixed memory leak in wxGrid::UpdateAttr[Rows][Or][Cols] (patch 1104355)</p>
<p>For efficiency reasons, text controls no longer set the string for
each text updated event, but rather query for the string value only
when GetString is called from an event handler.</p>
<p>Added wx.SL_INVERSE style which will cause wx.Slider to invert the min
and max ends of the slider.</p>
<p>Several patches applied, such as #1111174, #1110252 and others, that
make the generic wx.TreeCtrl (used on wxGTK and wxMac) be more
conistent with the wxMSW native wx.TreeCtrl.</p>
<dl class="docutils">
<dt>XRCed:</dt>
<dd><ul class="first last simple">
<li>Edit-&gt;Locate command (Ctrl-L) for quick selection of items.
Works with event-handling controls (buttons, text fields) but
not with labels/sizers.</li>
<li>Some improvements: relative paths for files supplied as command-
line argument work correctly, notebook panels are highlighted
better.</li>
</ul>
</dd>
</dl>
<p>wxMac: Fixed a long-standing issue where wxSlider controls with a
hardcoded size would misplace their labels behind the slider control.</p>
<p>wx.HtmlListBox fixed so calling RefreshLine(s) will cause the data for
that line to be refetched from the overridden methods in the derived
class.</p>
<p>The default DoGetBestSize now includes the difference (if any) between
the client size and total size of the window, (such as the size of
borders.)  Code that sets the client size using the best size, or that
added extra space to sizers to compensate for this bug may need to be
changed.</p>
<p>Can suppress themed notebook pages with the wxNB_NOPAGETHEME style or
setting system option msw.notebook.themed-background to 0.</p>
<p>wxSyledTextCtrl updated to use Scintilla 1.62.</p>
<p>Can now set the msw.window.no-clip-children system option to 1 to
eliminate weird refresh behaviour (delays between a window being
erased and repainted, giving a ghostly gradual-redraw effect). May be
a temporary 'fix' until properly fixed before 2.6.</p>
<p>wxMac:  Toolbar is now more native looking with borderless toolbar
buttons.</p>
<p>wxMac: Switched wx.Bitmap to use newer Quartz object types and APIs
internally.  This results in faster display and better alpha support.</p>
<p>Added wx.DatePickerCtrl.</p>
<p>wx.html.HtmlWindow now supports background images.</p>
<p>Added wx.lib.gestures module from Daniel Pozmanter which supports
using Mouse Gestures in an application.</p>
<p>wxGTK2: ENTER and LEAVE mouse events are now sent for multi-line text
controls.</p>
<p>wxMSW:  &quot;Alt&quot; key (VK_MENU) now results in WXK_ALT keyboard event, not
WXK_MENU</p>
<p>Added modules from Peter Yared and Morgan Hua that implement the wx
Doc/View framework in pure Python code.  See wx.lib.docview for the
base implementation and wx.lib.pydocview for Python-specific
extensions.  There are also a couple sample applications located in
samples/docview.</p>
<p>Added GetBitmap, GetIcon to wx.ImageList.</p>
<p>wxGTK wx.Button.SetLabel no longer invalidates/resets the font.</p>
<p>wx.Sizer.AddWindow, AddSizer, AddSpacer and etc. have now been
undeprecated at the request of Riaan Booysen, the Boa Constructor team
lead.  Boa needs them to help keep track of what kind of item is being
managed by the sizer.  They are now just simple compatibility aliases
for Add, and etc.</p>
<p>The old C++ version of the OGL lib is no longer built by default.  Use
the Python version in the wx.lib.ogl package instead.</p>
<p>The wx.iewin module is no longer built by default.  You can use the
wx.lib.iewin version instead.</p>
<p>Fixed wx.BufferedPaintDC for scrolled windows to work whether the
buffer is covering only the client area or the full virtual area of
the scrolled window.  By default it will assume that only the client
area is covered.  This is different than the old behavior so to
indicate that the entire virtual area is covered simply add a
style=wx.BUFFER_VIRTUAL_AREA parameter.</p>
<p>wx.gizmos.TreeListCtrl:  Add support for the EVT_TREE_ITEM_GETTOOLTIP
event.</p>
<p>Added Resize, SetRGBRect, Size, and GetOrFindMaskColour methods to
wx.Image.</p>

<p>wxMac focus and border refreshes corrected.</p>
<p>Updated internal PNG library.</p>
<p>wxMac fix for metal appearance on wx.ToolBar.</p>
<p>wx.grid.Grid fix allowing DoGetBestSize to be called before CreateGrid
(which means that a min size doesn't need to be specified.)</p>
<p>wxMac fix for not sending a native click to a control if it is not
enabled (does an enable itself)</p>
<p>Added wx.lib.ogl.DrawnShape, and fixed various little bugs in the new
OGL.</p>
<p>Added support to XRC and XRCed for the 3-state checkbox flags and also
for wx.ToggleButton.  Updated the generic window styles supported by
XRCed.</p>
<p>It is now possible to create &quot;stock&quot; buttons.  Basically this means
that you only have to provide one of the stock IDs (and either an
empty label or a label that matches the stock label) when creating the
button and wxWidgets will choose the stock label to go with it
automatically.  Additionally on the platforms that have a native
concept of a stock button (currently only GTK2) then the native stock
button will be used.  For example, the following will result in a
button with &quot;Cancel&quot; as the label and if run on wxGTK2 then there will
also be an image of a red X:</p>
<pre class="literal-block">
b = wx.Button(parent, wx.ID_CANCEL)
</pre>
<p>Added wx.lib.ticker.Ticker class from Chris Mellon.</p>
<p>Fix some incorrect clipping regions in wxSTC on wxGTK.</p>
<p>Added wrapper for wx.grid.Grid.GetOrCreateCellAttr.</p>
<p>Removed my copy of distutils from the wxPython source tree.  Now that
I am no longer doing builds on Python 2.1 the newest distutils is no
longer needed.  (There is still one small bug in Python 2.2 distutils
on win32, but it is easily worked around.) This sovles the problem of
incorrect builds on some systems where the system installed distutils
has been patched to behave slightly differently, for example SuSE on
x86_64 or Chandler's build.</p>
<p>Updated to SWIG 1.3.22 (plus my patch.)  See wxPython/SWIG/README.txt
in the source tree if you need to use SWIG when building your own copy
of wxPython, or other extension modules that need to integrate with
the wxPython modules.</p>
<p>Added wx.Frame.RequestUserAttention which, if the platform suports it,
will do something (such as flash the task bar item) to suggest to the
user that they should look at that window.</p>
<p>&quot;Fixed&quot; wx.grid.Grid.SetDefaultEditor and SetDefaultRenderer by making
them register the editor or renderer for the &quot;string&quot; data type.</p>
<p>Added depth param to wx.Image.ConvertToBitmap.</p>
<p>Extended the wx.calendar.CalendarCtrl class with methods that get/set
a Python datetime or date object.  (These will only work with Python
2.3+) The methods are PySetDate, PyGetDate, PySetLowerDateLimit,
PySetUpperDateLimit, PySetDateRange, PyGetLowerDateLimit, and
PyGetUpperDateLimit.  Also, CalendarEvent was extended with PySetDate
and PyGetDate methods.</p>
<p>wxMSW: SetBackgroundColour on a wx.Choice or a wx.ComboBox will now
also set the colour of the dropdown.</p>
<p>wxMac: MessageDialog now supports wx.NO_DEFAULT style</p>
<p>wxMSW: added AssociateHandle and DissociateHandle to wx.Window</p>
<p>wxMac: fix for toolbar tooltips</p>
<p>wx.Sizer.Show (and Hide) now take an optional parameter specifying if
the item to be shown should be searched for recursivly in subsizers,
and return a boolean value indicating if the item was found.</p>
<p>wxMSW: fixed MaximizeEvent generation in wx.Frame</p>
<p>wxMSW: fixed sending duplicate EVT_COMBOBOX events</p>
<p>Smoother time estimation updates in wx.ProgressDialog (patch 992813)</p>
<p>Made wx.Listbook events more consistent with wx.Notebook ones (patch
1001271)</p>
<p>Fixed rounding errors in variable status bar panes widths computation
(patch 1030021)</p>
<p>Added possibility to specify printer bin (patch 910272)</p>
<p>wxMSW: fixed wx.ListCtrl's SetWindowStyleFlag() to not remove
WS_VISIBLE; also refresh the control automatically (closes bug
1019440)</p>
<p>Added wx.Choicebook, yet another notebook-like control.</p>
<p>wxMSW: Make radiobutton tab behaviour the same on MSW as in standard
MSW app, i.e. tab into the activated, not necessarily the first radio
button.</p>
<p>Added limited support for wxEventLoop (you can't derive from a
wx.PyEventLoop version yet...)  Updated and moved the sample showing
how to replace the MainLoop to samples/mainloop/mainloop.py.</p>
<p>The C++ xrc lib has been moved out of contrib and into the core, so it
is always built by default.  wxPython's build has also changed
accordingly and will build the xrc module as part of the core set of
modules built by default.  If you were axplicitly using BUILD_XRC then
it will no longer be recognized as a build option, otherwise you
should notice no difference.</p>
<p>wxMac: Fixed radio toolbar buttons to correctly untoggle the others
when a new one is selected.</p>
<p>wxMac: Fixed GetLineLength and GetLineText for MLTE text controls</p>
<p>wxMac: wx.TaskBarIcon is implemented by allowing you to change the
app's icon on the Dock and also specifying a menu that should be
merged with the normal dock popup menu.  See the MigrationGuide for
more details and a warning.</p>
<p>Added wx.TopLevelWindow.IsActive() which tells you if the frame or
dialog is or containts the active window with the keyboard focus.</p>
<p>Added ability to create a font based on pixel size rather than point
size via the FontFromPixelSize constructor.</p>
<p>Updated the Scintilla used by StyledTextCtrl to version 1.61</p>
<p>Improved image HitTest for TreeListCtrl.</p>
<p>Added wx.App.IsMainLoopRunning.</p>
<p>wxGTK: Make wxComboBox spit out a bit fewer surplus events when

<p>wx.ADJUST_MINSIZE is now the default behaviour for window items in
sizers.  This means that the item's GetMinSize and/or GetBestSize will
be called when calculating layout and the return value from that will
be used for the minimum size used by the sizer.  The wx.FIXED_MINSIZE
flag was added that will cause the sizer to use the old behaviour in
that it will <em>not</em> call the window's methods to determine the new best
size, instead the minsize that the window had when added to the sizer
(or the size the window was created with) will always be used.  Please
see the Sizers section in the Migration Guide for more details.</p>
<p>Added new MaskedEditControl code from Will Sadkin.  The modules are
now locaed in their own sub-package, wx.lib.masked.  Demos updated.</p>
<p>The changes that implemented the incompatible wx.DC methods in 2.5.1.5
have been reverted.  The wx.DC methods are now compatible with the 2.4
implemetation.  In addition a set of renamed methods have been added
that take wx.Point and/or wx.Size objects instead of individual
parameters.</p>
<p>Added wx.lib.mixins.listctrl.TextEditMixin, a mixin class that allows
all columns of a wx.ListCtrl in report mode to be edited.</p>
<p>Deprecated the wx.iewin module.</p>
<p>Deprecated the wx.Sizer.AddWindow, AddSizer, AddSpacer methods as well
as their Insert* and Prepend* counterparts.</p>
<p>Added a generic StaticBitmap class in wx.lib.statbmp for the same
reasons that stattext was created, so it could be mouse sensitive on
all platforms like normal windows.  Also updated stattext.py and
buttons.py to handle attribute (font &amp; colour) defaults and
inheritance the new way.  If you have custom controls of your own you
should review stattxt.py or one of the others to see how it is to be
done.</p>
<p>wx.InitAllImageHandlers is now an empty function that does nothing but
exist for backwards compatibility.  The C++ version is now called
automatically when wxPython is initialized.  Since all the handlers
are included in the wxWidgets shared library anyway, this imposes only
a very small amount of overhead and removes several unneccessary
problems.</p>
<p>Replaced wx/lib/pubsub.py with a version that uses weak references to
track the subscribers, plus other fixes/additions.  Thanks go to
Oliver Schoenborn and Robb Shecter.</p>
<p>wxGTK now uses gtk_init_check so wxPython can raise an exception if
there is no DISPLAY available or other initializaion problem.</p>
<p>wx.GetKeyState now has an implementation for wxGTK and is able to
detect the up/down or toggle state of modifier and toggle keys.</p>
<p>The LC_NUMERIC locale is now reset back to &quot;C&quot; (compatibility) when
running on wxGTK to work around the fact that GTK requires the locale
to be set to the system settings but Python depends on LC_NUMERIC
remaining compatible with &quot;C&quot;.</p>
<p>Switched gizmos.TreeListCtrl to the newer version of the code from the
wxCode project.</p>
<p>OGL is dead! LONG LIVE OGL!  (Oops, sorry.  A bit of my dramatic side
leaked out there...)  The wx.ogl module has been deprecated in favor
of the new Python port of the OGL library located at wx.lib.ogl
