-// $Log$
-// Revision 1.19 1999/02/20 09:02:59 RD
-// Added wxWindow_FromHWND(hWnd) for wxMSW to construct a wxWindow from a
-// window handle. If you can get the window handle into the python code,
-// it should just work... More news on this later.
-//
-// Added wxImageList, wxToolTip.
-//
-// Re-enabled wxConfig.DeleteAll() since it is reportedly fixed for the
-// wxRegConfig class.
-//
-// As usual, some bug fixes, tweaks, etc.
-//
-// Revision 1.18 1999/01/30 08:17:27 RD
-//
-// Added wxSashWindow, wxSashEvent, wxLayoutAlgorithm, etc.
-//
-// Various cleanup, tweaks, minor additions, etc. to maintain
-// compatibility with the current wxWindows.
-//
-// Revision 1.17 1999/01/30 07:30:12 RD
-//
-// Added wxSashWindow, wxSashEvent, wxLayoutAlgorithm, etc.

-// Various cleanup, tweaks, minor additions, etc. to maintain
-// compatibility with the current wxWindows.
-//
-// Revision 1.16 1998/12/17 14:07:39 RR
-//
-// Removed minor differences between wxMSW and wxGTK
-//
-// Revision 1.15 1998/12/15 20:41:19 RD
-// Changed the import semantics from "from wxPython import *" to "from
-// wxPython.wx import *" This is for people who are worried about
-// namespace pollution, they can use "from wxPython import wx" and then
-// prefix all the wxPython identifiers with "wx."
-//
-// Added wxTaskbarIcon for wxMSW.
-//
-// Made the events work for wxGrid.
-//
-// Added wxConfig.
-//
-// Added wxMiniFrame for wxGTK, (untested.)
-//
-// Changed many of the args and return values that were pointers to gdi
-// objects to references to reflect changes in the wxWindows API.
-//
-// Other assorted fixes and additions.
-//
-// Revision 1.14 1998/11/25 08:45:25 RD
-//
-// Added wxPalette, wxRegion, wxRegionIterator, wxTaskbarIcon
-// Added events for wxGrid
-// Other various fixes and additions
-//
-// Revision 1.13 1998/11/15 23:03:45 RD
-// Removing some ifdef's for wxGTK
-//
-// Revision 1.12 1998/11/03 09:21:08 RD

-//
-// Version 0.4 of wxPython for MSW.
-//
-// Revision 1.9 1998/09/25 13:28:52 VZ
-//
-// USE_xxx constants renamed to wxUSE_xxx. This is an incompatible change, you
-// must recompile everything after upgrading!
-//
-// Revision 1.8 1998/08/27 21:59:08 RD
-// Some chicken-and-egg problems solved for wxPython on wxGTK
-//
-// Revision 1.7 1998/08/27 00:00:26 RD
-// - more tweaks
-// - have discovered some problems but not yet discovered solutions...
-//
-// Revision 1.6 1998/08/18 21:54:12 RD
-//
-// ifdef out some wxGTK specific code
-//
-// Revision 1.5 1998/08/18 19:48:17 RD
-// more wxGTK compatibility things.
-//
-// It builds now but there are serious runtime problems...
-//
-// Revision 1.4 1998/08/16 04:31:06 RD
-// More wxGTK work.
-//
-// Revision 1.3 1998/08/15 07:36:36 RD
-// - Moved the header in the .i files out of the code that gets put into
-// the .cpp files. It caused CVS conflicts because of the RCS ID being
-// different each time.
-//
-// - A few minor fixes.
-//
-// Revision 1.2 1998/08/14 23:36:36 RD
-// Beginings of wxGTK compatibility
