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!

- 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

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.

- 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

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.

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

All (GUI):

- 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 files in wxImage added (Chris Elliott)

wxMSW:

- huge (40*) speed up in wxMask::Create() (=> much faster toolbar creation)
- fixed flicker in wxTreeCtrl::SetItemXXX()
- fixed redraw problems in dynamically resized wxStaticText
- fixed wxProgressDialog for ranges > 65535
- wxFontEnumerator now returns all fonts, not only TrueType ones

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
