Fixed Cut command, added support for MenuBar inside Frame/Dialog.

Recent Changes for wxPython
=====================================================================

2.7.0.0
-------

The following deprecated items have been removed:

    * wx.Bitmap SetQuality and GetQuality methods

    * The wx.GetNumberFromUser function

    * wx.EVT_LIST_GET_INFO and wx.EVT_LIST_SET_INFO

    * wx.BookCtrlSizer and wx.NotebookSizer

    * The PostScript-specific methods of wx.PrintData

    * wx.PrintDialogData SetSetupDialog and GetSetupDialog methods

    * wx.FontMapper SetConfig method

    * wx.html.HtmlSearchStatus.GetContentsItem method

    * wx.html.HtmlHelpData.GetContents, GetContentsCnt, GetIndex, and
      GetIndexCnt methods


wx.EventLoop is now implemented for wxMac.

Added wxPython wrappers for the new wx.Treebook and wx.Toolbook
classes. 

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.

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 "base_" 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::

    def OnBeginDocument(self, start, end):
	# do something here
	return self.base_OnBeginDocument(start, end)

You can now call the base class method the normal way, like this::

    def OnBeginDocument(self, start, end):
	# do something here
	return Printout.OnBeginDocument(self, start, end)

Or like this with super()::

    def OnBeginDocument(self, start, end):
	# do something here
	return super(MyPrintout, self).OnBeginDocument(start, end)


Note that the old way with the "base_" function still works, but you
will get a DeprecationWarning from calling base_OnBeginDocument.  The
classes affected by this are:

    * wx.DropSource
    * wx.DropTarget
    * wx.TextDropTarget
    * wx.FileDropTarget
    * wx.PyLog   (also added the ability to override Flush)
    * wx.PyApp   (also added the ability to override ExitMainLoop)
    * wx.Printout
    * wx.PyPrintPreview
    * wx.PyPreviewFrame
    * wx.PreviewControlBar
    * wx.Process
    * wx.PyControl
    * wx.PyPanel
    * wx.PyScrolledWindow
    * wx.PyWindow
    * wx.Timer
    * wx.grid.PyGridCellRenderer
    * wx.grid.PyGridCellEditor
    * wx.grid.PyGridCellAttrProvider
    * wx.grid.PyGridTableBase
    * wx.html.HtmlWindow
    * wx.wizard.PyWizardPage


Added the wx.DC.GradientFillConcentric and wx.DC.GradientFillLinear
methods.




2.6.3.0
-------

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.

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.




2.6.2.1
-------
* 10-Jan-2006

wxMSW: Fix for bug #1211907, popup menu indenting inconsistent with
bitmaps.

wxMac: Don't send an event for wx.RadioButton deselections, just the
selections.  This was done to make it consistent with the other
platforms.

wxMSW: Always set flat toolbar style, even under XP with themes: this
is necessary or separators aren't shown at all.

Fixes for bug #1217872, pydocview.DocService not correctly initialized.

Fix for bug #1217874, Error in parameter name in DocManager.CreateView.

Added wrappers for the wx.RendererNative class.

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.

Docview and IDE patch from Morgan Hua with fix for bug #1217890
"Closing view crashes Python" plus some new features::

    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 "Notepad" extension (under windows) that
    will exec Notepad on the currently open file.  A new "Notepad"
    menu item will appear under the Tools menu.

Some fixes to XRCed to make encoding errors a bit more user friendly.

XRCed changes from Roman Rolinsky:

    * 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).

    * Use system clipboard for Copy/Paste.

    * Improved some dialogs (window styles, growable cols). Changed
      the range for wxSpinCtrl min/max to all integers (default 0/100
      is not always good).

Updates for wx.lib.foldpanelbar and wx.lib.hyperlink from Andrea
Gavana.

Fix for Bug #1283496: wxPython TheClipboard class causes problems for
pychecker.  Ensure the app has been created before initializing
wx.TheClipboard.

Fix for Bug #1352602: FileBrowseButtonWithHistory can't type in Value.

wxHTML: Added space after list item number.

wx.lib.printout:  Applied patch #1384440.

wxMSW:  Fix for Bug #1293225 Window_FromHWND crashes if parent is
None.

Fix for Bug #1261669, use a wx.TE_RICH2 style for the Process demo so
it doesn't fill up too soon.

Applied Patch #1354389: wxPython MenuItem SetBitmaps fix.

Applied Patch #1239456: wxPython wx.DataObject.GetAllFormats fix.

Applied Patch # #1230107 which allows image handlers to be written in
Python by deriving from wx.PyImageHandler.

Applied patch #1072210: generalize printout.py to allow text printing.

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() &
SetCurrent(). Very handy if you have multiple throbbers that you want
to synchronize with a single timer.

Fix for bug #1336711: wx.lib.calendar.CalenDlg can yield incorrect
result.

Applied patch from Morgan Hua for updates to ActiveGrid code
(pydocview, ActiveGrid IDE, etc.)

Applied patch #1326241: Supporting "setup.py install --install-headers=path"

Applied patch from Morgan Hua to fix bug #1219423: CommandManager
should not repeat old commands after a branch.

Applied patch #1238825 adding search backward capabilities to the
demo.  Modified to use the up/down options in the wx.FindReplaceDialog
instead of a separate menu item.

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!

wxMSW: wx.lib.iewin.IEHtmlWindow now properly handles tabbing, return
and other special keys properly.

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:

    * The Autocomplete and Calltip windows can now be opened manually
      with Ctrl-Space and Ctrl-Shift-Space.

    * In the stand alone PyCrust app the various option settings,
      window size and position, and etc. are saved and restored at the
      next run.

    * Added a help dialog bound to the F1 key that shows the key
      bindings.

    * Added a new text completion function that suggests words from
      the history.  Bound to Shift-Return.

    * F11 will toggle the maximized state of the frame.

    * switched to Bind() from wx.EVT_*().

    * Display of line numbers can be toggled.

    * F12 toggles a "free edit" 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.

    * Ctrl-Shift-F will fold/unfold (hide/show) the selected lines.

    * General code cleanup and fixes.

    * Use wx.StandardPaths to determine the location of the config
      files.

    * Use wx.SP_LIVE_UPDATE on crust and filling windows.

    * 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.

    * 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.

    * 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.

    * Added an option to skip the running of the startup code when
      PyShell or PyCrust starts.

    * 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.

    * Added an option for whether to insert text for function
      parameters when popping up the call tip.

    * Added Find and Find-Next functions that use the
      wx.FindReplaceDialog.


Applied patches from Will Sadkin for wx.lib.masked modules:

    * Now ignores kill focus events when being destroyed.

    * Added missing call to set insertion point on changing fields.

    * Modified SetKeyHandler() to accept None as means of removing
      one.

    * Fixed keyhandler processing for group and decimal character
      changes.

    * Fixed a problem that prevented input into the integer digit of a
      integerwidth=1 numctrl, if the current value was 0.

    * Fixed logic involving processing of "_signOk" flag, to remove
      default sign key handlers if false, so that
      SetAllowNegative(False) in the NumCtrl works properly.

    * 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.

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.

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.

Added wx.SizerItem.SetUserData

A variety of updates to wx.lib.floatcanvas, including Added
DrawObjects, including a ScaledTextBox, with auto-wrapping, etc, and
Scaled and Unscaled Bitmap Objects.

       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, ...) --->  (...(x,y), ...) 




2.6.1.0
-------
* 4-June-2005

wx.ListCtrl: patch #1210352, fixes editing in generic wx.ListCtrl with
wx.LC_EDIT_LABELS.

Applied patch #208286, MediaCtrl DirectShow rewrite.

DocView patches from Morgan Hua: bug fixes, and additional SVN
commands, also added a default template that uses the text editor for
any unknown file type.

wxMSW: Use the system IDC_HAND cursor for wx.CURSOR_HAND and only fallback
to the strange wxWidgets version if the system one is not available.

wx.grid.Grid: Merge the cell size attribute the same way that other
attributes are merged, e.g., if it is already set to a non-default
value in the current GridCellAttr object then don't merge from the
other.

wx.lib.evtmgr: Fixed to use wx._core._wxPyDeadObject

wx.lib.gridmovers: Don't scroll when the mouse is dragged outside of
the grid, unless the mouse is kept in motion.

wxMSW:  Applied patch #1213290 incorrect logic in
wx.TopLevelWindow.ShowFullScreen.

Applied patch #1213066 correct device names for Joystick in Linux.

wxGTK: Applied patch #1207162 wx.TextCtrl.SetStyle fix for overlapping
calls.

wx.FileConfig: fixed DeleteEntry to set the dirty flag properly so the
change will get written at the next flush.





2.6.0.1
-------
* 30-May-2005

Added wx.BrushFromBitmap to create a stippled brush in a single step.
Also added missing brysh style flags: wx.STIPPLE_MASK
wx.STIPPLE_MASK_OPAQUE.

wxMSW: Fix for default control colours when the system text fg colour
is not black.

wxGTK: Patch #1171754, It is now possible to have a menu item that
both has an icon and is a submenu.

wxMSW: Patch #1197009, better refreshes when windows are moved and
resized.

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.

Fixed the typemap that converts a Python list of strings to a
wxArrayString so it uses the wxPython default encoding.

Several docstrings added and updated.  Lots more to go.

wxMac: Strings added to the clipboard or used in DnD no longer have an
extra null character at the end.

Added wx.GetXDisplay that returns a raw swigified pointer for the X11
Display, or None for the non-X11 platforms.

wxMenu: Don't send an event when selecting an already selected radio
item.

Added wx.LaunchDefaultBrowser.

wxMSW: Fixed erroneous selection of content in wx.ComboBox when within
a wx.StaticBox.

wxMSW: Fixed alpha blitting to take into account source position.

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.

Added alternate constructors for wx.Font: wx.FontFromPixelSize,
wx.FFont, wx.FFontFromPixelSize.  See the docstrings or new api docs
for details.

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.

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 "2.6-unicode" 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::

	 import wxversion
	 wxversion.select("2.6-unicode", True)
	 import wx

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.

wxMSW:  Fix for wrong sash colour of wx.SplitterWindow in the silver
theme on XP.

Added a wx.xrc.XmlResourceHandler for the Ticker class.  See
wx/lib/ticker_xrc.py

wxSTC: Fixed CmdKeyAssign key bindings for Ctrl-Backspace.

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.

XRCed: Use wx.GetDefaultPyEncoding/wx.SetDefaultPyEncoding for
changing active encoding.  Fixed pasting siblings (Ctrl key pressed
while pasting).

wx.lib.filebrowsebutton: Bug fix from Chad Netzer for when
self.history is None.

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.

wxMSW: setting foreground colour for wx.CheckBox now works when using
XP themes.

More updates to the docview library modules and sample apps from the
ActiveGrid folks.  Their sample IDE is now able to integrate with
Subversion.

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.

wxGTK:  Add wxSTAY_ON_TOP support [Patch 1206023]

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.

wxGTK: Setting background colour of a window now only affects the
window itself, not the borders, scrollbars, etc.  (Bug #1204069)

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.

wxMac: Applied patch for bug #1206181 Option-key decodes are wrong,
also applied patch for bug #1205691 Modified Fn keys don't work.

wx.Image: Fixed to preserve alpha channel in Rotate90 method.

wxMSW: Fixed incorrect background colour on wx.CheckListBox.

wxMSW: Fixed drawing of owner drawn buttons with multiline labels

Removed a bunch of unnecessary files, and removed or replaced images
that we're not sure of their origin or license.

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.

wxMSW: When converting a wx.Icon to a bitmap check if the icon has an
alpha channel and set the bitmap to use it.

Fixed the wrong class name used in wx.PyScrolledWindow's call to
_setCallbackInfo.

wxMSW: patch #1207202, Fixes GDI leak when using stock cursors.

wx.calendar.CalendarCtrl: Patch #1207531, Keeps the CalendarCtrl wide
enough even when the weekday names for the locale are shorter than
usual.

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.)





2.6.0.0
-------
* 26-Apr-2005

wxMSW: Fixed wx.TransientPopupWindow (and therefore wx.TipWindow) to
auto-dismiss when the mouse is clicked outside of the popup like it is
supposed to.

wxMSW: Fixed bug #1167891 wx.Notebook display problem with wx.NB_MULTILINE.

wxMSW: Fixed bad cliping of hidden windows inside of wx.StaticBox.

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'.

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 <--> wxString conversions.  The "Raw"
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 "UTF8" 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.)

      ===================  ====================
      AddTextRaw           AddTextUTF8
      InsertTextRaw        InsertTextUTF8
      GetCurLineRaw        GetCurLineUTF8
      GetLineRaw           GetLineUTF8
      GetSelectedTextRaw   GetSelectedTextUTF8
      GetTextRangeRaw      GetTextRangeUTF8
      SetTextRaw           SetTextUTF8
      GetTextRaw           GetTextUTF8
      AppendTextRaw        AppendTextUTF8
      ===================  ====================


wx.stc.StyledTextCtrl:  Added the StyleSetFontEncoding(style, enc)
method that allows you to set the encoding to be used by the font for
a particular style.

wxMac: Fixed wx.ComboBox to forward the EVT_CHAR, EVT_KEY_DOWN,
EVT_KEY_UP and EVT_TEXT events from its embedded text control.

wxMac: Corrected refresh bugs in wxGrid.

XRCed: Updated to version 0.1.5.
    * Added wxWizard, wxWizardPageSimple (only from pull-down menu).
    * Hide command for test window.
    * Replacing classes works better.
    * Added Locate tool.




2.5.5.1
-------
* 8-Apr-2005

wxMSW: Fixed bug #1022383, 'several ComboBoxes appear selected'

wx.grid.Grid: Fixed bug #1163384.  Moved the code that handles
activating the cell editors to a EVT_CHAR event handler.  This is done
so the character inserted into the editor will be the "cooked" char
value (including accented or composed keys) rather than the raw code
provided by the EVT_KEY_DOWN event.

Added orient parameter to wx.MDIParentFrame.Tile()

wxMSW: wxTextCtrl with wx.TE_RICH2 style now uses RichEdit 4.1 if
available.

Added GetCount, GetCountRGB, and GetCountColour methods to
wx.ImageHistogram.

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.
This also fixes the Freeze/Thaw problems that some people had with
2.5.4.1.

wx.SplitterWindow: Send EVT_SPLITTER_SASH_POS_CHANGED only once after
end of dragging and not after each CHANGING event (modified patch
#1076226)

wx.glcanvas.GLCanvas: applied patch fixing problems with X server
crash when using nVidia cards (patch 1155132)

wx.lib.mixins.listctrl: Patches from Toni Brkic:
   * Bugfix for TextEditMixin when the view can't be scrolled
   * Enhancement for ListCtrlAutoWidthMixin, allowing it to manage
     the width of any column.

wxMac: removal and reusing toolbar tools like the other platforms is
now possible.

wxMac: Correct radio tool selection after calling Realize a 2nd time.

wxMSW: Applied patch #1166587, removes all flicker from wx.StaticBox

Added wx.lib.foldpanelbar, Andrea Gavana's port of Jorgen Bodde's C++
wxFoldPanelBar classes to Python.

wxGTK: Applied patch #1173802, reimplementation of GtkFileChooser
wxFileDialog by Mart Raudsepp.  Note that this new file dialog is only
used on GTK2 >= 2.4.  For earlier GTK2 versions and GTK1 then the
older generic file dialog is used.

wxMSW: fixes to static box borders calculations (finalizes patch
#1166587)

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.

Added MDI support to XRC

Added wx.animate module and a demo.  The wx.animate module provides a
control that is able to display an animated GIF file.

wx.lib.plot.py: Applied patch from Werner F. Bruhin that allows either
vertical and/or horizontal gridlines.

wxMSW: Extra space given for top border of wx.StaticBoxSizer so the
upper line is not cliped when there is no label.

wxMSW: Restored old behaviour of wx.StaticBox.SetBackgroundColour only
affecting the label.

wxMSW: Fixed missing EVT_RIGHT_DOWN and EVT_TREE_ITEM_RIGHT_CLICK
events in a wx.TreeCtrl.

Added wx.GetTopLevelWindows() function which returns a copy of the
list of top-level windows that currently exist in the application.

Updated docview library modules and sample apps from the ActiveGrid
folks.

Added the ActiveGrid IDE as a sample application.




2.5.4.1
-------
* 16-Mar-2005

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.

Added wx.Sizer.GetItem method which returns the wx.SizerItem for the given
wx.Window, wx.Sizer or position index.

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().

Some XRC changes:
    - Added 'icon' property to wxFrame and wxDialog
    - No longer ignores menu bitmaps on non-MSW platforms
    - Notebook page bitmaps are now supported
    - added system colours and fonts support (based on patch #1038207)

wxMSW: fix for [ 1052989 ] TextCtrl.SetBackgroundColour(wx.NullColour)
bug.

Added wx.PasswordEntryDialog analagous to wx.TextEntryDialog, allows
detecting entering an empty string vs. cancel unlike the
wx.GetPasswordFromUser dialog function.

OGL patch from Shane Holloway:

    Two simple problems found in the new python ogl code.  First is
    the patch for _canvas.py.  Essentially::

        dx = abs(dc.LogicalToDeviceX(x - self._firstDragX))
        dy = abs(dc.LogicalToDeviceY(y - self._firstDragY))

    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.

    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.  ;)

Fixed GetSaveData and SetSaveData in wx.lib.multisash to not depend on
the default way that class objectss are converted to strings.

Fixed problem in StyledTextCtrl.Set[HV]ScrollBar that could leave the
internal scrollbar visible.

Added wx.StandardPaths which provides methods for determining standard
system paths for each platform.

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.

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.

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...

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.

wxGTK: Patch applied for Freeze()/Thaw() for wxTextCtrtl.

Added "gravity" 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.

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.

wxMSW:  Fix wx.TreeCtrl to end label editing if the control loses
focus (a slightly modified patch 1084592.)

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.

wxMSW: Much work to correct painting (or leaving transparent) of
control backgrounds, properly using background themes on XP, etc.

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.

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:

    * 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.

    * 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.

    * The "this" attribute of all SWIGged classes is no longer a
      string containing a "swigified pointer", 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().

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 "ascii", which would result in
errors if the strings contained character codes >= 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 `locale.getdefaultlocale()[1]` when wxPython is first
imported.  Please see http://www.alanwood.net/demos/charsetdiffs.html
for information on the differences between the common latin/roman
encodings.

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 `wx.Button`
to the sizer, and be sure to create the buttons using the standard
ID's.  Then call `Realize` and the sizer will take care of the rest.

wxMSW Toolbar: pass correct tool id (and not always -1) to the
EVT_TOOL_RCLICKED handler

wxGTK: Applied patch for combo box SELECTED events (no longer get
lots of surplus events)

wxGTK: Applied patch for proper menu highlight colour detection in
wx.SystemSettings.

wxGTK: Commited scrollbar patch #1093339 which sends lineup, linedown
events based on intercepting the mouse down events.

wxGTK: Applied patch #1102789 which solved conflicts between wxWidgets
and GTK+'s context menu code.

wxGTK: Applied patch #1100327 for correct feedback from DND actions
(not all actions are allowed).

Fixed memory leak in wxGrid::UpdateAttr[Rows][Or][Cols] (patch 1104355)

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.

Added wx.SL_INVERSE style which will cause wx.Slider to invert the min
and max ends of the slider.

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.

XRCed:
    * Edit->Locate command (Ctrl-L) for quick selection of items.
      Works with event-handling controls (buttons, text fields) but
      not with labels/sizers.
    * Some improvements: relative paths for files supplied as command-
      line argument work correctly, notebook panels are highlighted
      better.

wxMac: Fixed a long-standing issue where wxSlider controls with a
hardcoded size would misplace their labels behind the slider control.

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.

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.

Can suppress themed notebook pages with the wxNB_NOPAGETHEME style or
setting system option msw.notebook.themed-background to 0.

wxSyledTextCtrl updated to use Scintilla 1.62.

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.

wxMac:  Toolbar is now more native looking with borderless toolbar
buttons.

wxMac: Switched wx.Bitmap to use newer Quartz object types and APIs
internally.  This results in faster display and better alpha support.

Added wx.DatePickerCtrl.

wx.html.HtmlWindow now supports background images.

Added wx.lib.gestures module from Daniel Pozmanter which supports
using Mouse Gestures in an application.

wxGTK2: ENTER and LEAVE mouse events are now sent for multi-line text
controls.

wxMSW:  "Alt" key (VK_MENU) now results in WXK_ALT keyboard event, not
WXK_MENU

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.

Added GetBitmap, GetIcon to wx.ImageList.

wxGTK wx.Button.SetLabel no longer invalidates/resets the font.

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.

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.

The wx.iewin module is no longer built by default.  You can use the
wx.lib.iewin version instead.

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.

wx.gizmos.TreeListCtrl:  Add support for the EVT_TREE_ITEM_GETTOOLTIP
event.

Added Resize, SetRGBRect, Size, and GetOrFindMaskColour methods to
wx.Image.

Added wx.Rect.IsEmpty

wxGTK:
    - Corrected wx.ListBox selection handling
    - Corrected default button size handling for different themes
    - Corrected splitter sash size and look for different themes
    - Fixed keyboard input for dead-keys




2.5.3.1
-------
* 9-Nov-2004

wxMac focus and border refreshes corrected.

Updated internal PNG library.

wxMac fix for metal appearance on wx.ToolBar.

wx.grid.Grid fix allowing DoGetBestSize to be called before CreateGrid
(which means that a min size doesn't need to be specified.)

wxMac fix for not sending a native click to a control if it is not
enabled (does an enable itself)

Added wx.lib.ogl.DrawnShape, and fixed various little bugs in the new
OGL.

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.

It is now possible to create "stock" 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 "Cancel" as the label and if run on wxGTK2 then there will
also be an image of a red X::

       b = wx.Button(parent, wx.ID_CANCEL)


Added wx.lib.ticker.Ticker class from Chris Mellon.

Fix some incorrect clipping regions in wxSTC on wxGTK.

Added wrapper for wx.grid.Grid.GetOrCreateCellAttr.

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.

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.

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.

"Fixed" wx.grid.Grid.SetDefaultEditor and SetDefaultRenderer by making
them register the editor or renderer for the "string" data type.

Added depth param to wx.Image.ConvertToBitmap.

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.

wxMSW: SetBackgroundColour on a wx.Choice or a wx.ComboBox will now
also set the colour of the dropdown.

wxMac: MessageDialog now supports wx.NO_DEFAULT style

wxMSW: added AssociateHandle and DissociateHandle to wx.Window

wxMac: fix for toolbar tooltips

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.

wxMSW: fixed MaximizeEvent generation in wx.Frame

wxMSW: fixed sending duplicate EVT_COMBOBOX events

Smoother time estimation updates in wx.ProgressDialog (patch 992813)

Made wx.Listbook events more consistent with wx.Notebook ones (patch
1001271)

Fixed rounding errors in variable status bar panes widths computation
(patch 1030021)

Added possibility to specify printer bin (patch 910272)

wxMSW: fixed wx.ListCtrl's SetWindowStyleFlag() to not remove
WS_VISIBLE; also refresh the control automatically (closes bug
1019440)

Added wx.Choicebook, yet another notebook-like control.

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.

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.

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.

wxMac: Fixed radio toolbar buttons to correctly untoggle the others
when a new one is selected.

wxMac: Fixed GetLineLength and GetLineText for MLTE text controls

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.

Added wx.TopLevelWindow.IsActive() which tells you if the frame or
dialog is or containts the active window with the keyboard focus.

Added ability to create a font based on pixel size rather than point
size via the FontFromPixelSize constructor.

Updated the Scintilla used by StyledTextCtrl to version 1.61

Improved image HitTest for TreeListCtrl.

Added wx.App.IsMainLoopRunning.

wxGTK: Make wxComboBox spit out a bit fewer surplus events when
holding down the mouse button.

wxGTK: Enable key based navigation through notebook tabs as in the
native control with Left and right keys. Support for vetoing.

FloatCanvas updates from Chris Barker

PyPlot updates from Gordon Williams:
   - Added bar graph demo
   - Modified line end shape from round to square.
   - Removed FloatDCWrapper for conversion to ints and ints in
     arguments
   - Imported modules given leading underscore to name.
   - Added Cursor Line Tracking and User Point Labels.
   - Demo for Cursor Line Tracking and Point Labels.
   - Size of plot preview frame adjusted to show page better.
   - Added helper functions PositionUserToScreen and
     PositionScreenToUser in PlotCanvas.
   - Added functions GetClosestPoints (all curves) and GetClosestPoint
     (only closest curve) can be in either user coords or screen
     coords.

MaskedEdit updates from Will Sadkin:
    - Added '*' mask char that means "all ansii chars" (ords 32-255)
    - Added proper unicode support to masked controls and wx.tools.dbg
    - Fixed two reported missing import bugs introduced by package
      creation
    - Converted masked package doc strings to reST format for better
      epydoc support
    - lots of doc string improvements and function hiding to better
      reflect package's public contents.

Restructured the installer packages slightly to help facilitate having
multiple versions of wxPython installed at the same time.  See the
Migrarion Guide for more information.

Applied patch from Pim Van Heuven that modifies 4 files:
    - wxPython/demo/ListCtrl_edit.py (new demo)
    - wxPython/demo/Main.py (include new demo in demo app)
    - wxPython/wx/lib/mixins/listctrl.py (several improvements to
      TextEditMixin)
    - wxPython/wx/lib/wxpTag.py (some small fixes)

Added (thanks to Kevin Ollivier!) wrappers for wx.WebKitCtrl for the
OSX build.  Other platforms will raise an exception if you try to use
it.

wxPython on OSX can now be built in Unicode mode, can support multiple
version installs, and comes with an uninstaller script.





2.5.2.8
-------
* 27-Aug-2004

Predominantly a bug-fix release.

  * Fixed fatal error due to improper wrapping of wx.FSFile.

  * Fixed return type of EditableListBox.GetListCtrl

  * Give generic tree and list controls a DoGetBestSize so they play
    nicer with sizers when there is no minimal size.

  * Some tweaks in the demo and samples to correct layout, some
    flicker problems, and namespace use.

  * Add wx.Image.ConvertAlphaToMask

  * Minor corrections in wx.lib.dialogs

  * wx.FileHistory constructor now accepts the documented 2nd
    parameter.

  * Corrections for exceptions in the new ogl

  * Fixed XRCed to not use reparenting of windows to implement caching
    of property panels, since Reparent on wxMac is not implemented.

  * Add support for wxTAB_TRAVERSAL to the XRC handler for
    wxScrolledWindow.

  * Add support for all wxListBox styles to the XRC handler for
    wxCheckListBox.

  * Fix for wx.Listbook.DeleteAllPages to really delete everything.

  * wxGTK2 now supports alpha blended bitmap drawing

  * Made wx.grid.Grid play nicer with sizers.

  * etc.




2.5.2.7
-------
* 14-Aug-2004

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 *not* 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.

Added new MaskedEditControl code from Will Sadkin.  The modules are
now locaed in their own sub-package, wx.lib.masked.  Demos updated.

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.

Added wx.lib.mixins.listctrl.TextEditMixin, a mixin class that allows
all columns of a wx.ListCtrl in report mode to be edited.

Deprecated the wx.iewin module.

Deprecated the wx.Sizer.AddWindow, AddSizer, AddSpacer methods as well
as their Insert* and Prepend* counterparts.

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 & 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.

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.

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.

wxGTK now uses gtk_init_check so wxPython can raise an exception if
there is no DISPLAY available or other initializaion problem.

wx.GetKeyState now has an implementation for wxGTK and is able to
detect the up/down or toggle state of modifier and toggle keys.

The LC_NUMERIC locale is now reset back to "C" (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 "C".

Switched gizmos.TreeListCtrl to the newer version of the code from the
wxCode project.

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
