wxWindows 2 Change Log
----------------------

INCOMPATIBLE CHANGES SINCE 2.2.x
================================

wxBase:

- wxArray<T>::Remove(size_t) has been removed to fix compilation problems
  under 64 bit architectures, please replace it with RemoveAt() in your
  code.

- wxObject::CopyObject() and Clone() methods were removed because they
  simply don't make sense for all objects

- wxEvent now has a pure virtual Clone() method which must be implemented
  by all derived classes, if you have user-defined event classes please
  add "wxEvent *Clone() const { return new MyEvent(*this); }" line to them

All (GUI):

- the event type constants are not constants any more but are dynamically
  allocated during run-time which means that they can't be used as case labels
  in the switch()es, you must rewrite them to use if()s instead

  You may also define WXWIN_COMPATIBILITY_EVENT_TYPES to get the old behaviour
  but this is strongly discouraged, please consider changing your codei
  instead!

- wxDialog does not derive from wxPanel any longer - if you were using it in
  your code, please update it. The quick fix for the most cases is to replace
  the occurences of wxPanel with wxWindow.

- wxYES_NO is now wxYES | wxNO and the manifest values of both wxYES and wxNO
  have changed (to fix some unfortunate clashes), please check your code to
  ensure that no tests for wxYES or wxNO are broken: for example, the following
  will *NOT* work any longer:

        if ( flags & wxYES_NO )
                ... do something ...
        if ( flags & wxYES )
                ... do something else ...

- wxGLCanvas now derives directly from wxWindow, not wxScrolledWindow

- wxGridCellAttrProvider class API changed, you will need to update your code
  if you derived any classes from it

- wxImage::ComputeHistogram()'s signature changed to 
  unsigned long ComputeHistogram(wxImageHistogram&) const

wxMSW:

- build system changed: setup.h is not a static file in include/wx any more
  but is created as part of the build process under lib/<toolkit>/wx/include
  where <toolkit> is of the form (msw|univ)[dll][u][d]. You'll need to update
  the include path in your make/project files appropriately. Furthermore,
  xpm.lib is no longer used by wxMSW, it was superseded by the wxXPMDecoder
  class. You'll need to remove all references to xpm.lib from your 
  make/project files.

- child frames appear in the taskbar by default now, use wxFRAME_NO_TASKBAR
  style to avoid it, wxFRAME_FLOAT_ON_PARENT style is now obsolete and has no
  effect

- all overloads of wxDC::SetClippingRegion() combine the given region with the
  previously selected one instead of replacing it

Unix ports:

- You should use `wx-config --cxxflags` in your makefiles instead of
  `wx-config --cflags` for compiling C++ files. CXXFLAGS contains CFLAGS
  and the compiler flags for C++ files only, CFLAGS should still be used
  to compile pure C files.


OTHER CHANGES
=============

2.3.3
-----

wxBase:

- fixes to the command line parsing error and usage messages
- modified wxFileName::CreateTempFileName() to open the file atomically
  (if possible) and, especially, not to leak the file descriptors under Unix
- memory leak in wxHTTP fixed (Dimitri)
- fixes to AM_PATH_WXCONFIG autoconf macro
- added wxHashMap class that replaces type-unsafe wxHashTable and is modelled
  after STL hash_map

Unix (Base/GUI):

- wxWindows may be built using BSD and Solaris (and possibly other) make
  programs and not only GNU make

All (GUI):

- wxImage::ComputeHistogram() now uses wxImageHistogram instead of type-unsafe
  wxHashTable
- significantly improved native font support
- added IFF image handler
- fixed using custom renderers in wxGrid which was broken in 2.3.2
- support for multiple images in one file added to wxImage (TIFF and ICO formats)
- support for CUR and ANI files in wxImage added (Chris Elliott)
- wxTextCtrl::GetRange() added
- added wxGetFontFromUser() convenience function

wxMSW:

- small appearance fixes for native look under Windows XP
- refresh the buttons properly when the window is resized (Hans Van Leemputten)
- huge (40*) speed up in wxMask::Create()
- changing wxWindows styles also changes the underlying Windows window style
- fixed flicker in wxTreeCtrl::SetItemXXX()
- fixed redraw problems in dynamically resized wxStaticText
- improvements to wxWindows applications behaviour when the system colours
  are changed
- fixed wxProgressDialog for ranges > 65535
- wxFontEnumerator now returns all fonts, not only TrueType ones
- bugs in handling wxFrame styles (border/caption related) fixed
- showing a dialog from EVT_RADIOBUTTON handler doesn't lead to an infinite
  recursion any more
- wxTextCtrl with wxTE_RICH flag scrolls to the end when text is appended to it

wxGTK:

- wxDirDialog now presents the file system in standard Unix way
- wxButton now honours wxBU_EXACTFIT
- wxStaticBox now honours wxALIGN_XXX styles

wxHTML:

- fixed wxHtmlHelpController's cache files handling on big endian machines
- added blocking and redirecting capabilities to wxHtmlWindow via
  wxHtmlWindow::OnOpeningURL()
- fixed alignment handling in tables

2.3.2
-----

New port: wxUniv for Win32/GTK+ is now included in the distribution.

wxBase:

- wxRegEx class added
- wxGetDiskSpace() function added (Jonothan Farr, Markus Fieber)
- wxTextBuffer and wxTextFile(wxStream) added (Morten Hanssen)
- more fixes to wxMBConv classes. Conversion to and from wchar_t now works with
  glibc 2.2 as well as with glibc 2.1. Unix version now checks for iconv()'s
  capabilities at runtime instead of in the configure script.

All (GUI):

- support for virtual list control added
- column images in report mode of the list control
- wxFindReplaceDialog added (based on work of Markus Greither)
- wxTextCtrl::SetMaxLength() added (wxMSW/wxGTK)
- polygon support in wxRegion (Klaas Holwerda)
- wxStreamToTextRedirector to allow easily redirect cout to wxTextCtrl added
- fixed bug with using wxExecute() to capture huge amounts of output
