wxWidgets/include/wx/object.h
Vadim Zeitlin 59d3027c0c 1. wxTextCtrl::SetValue() moves the cursor to the end of text (as in GTK)
2. bug in wxThread::Delete() when the thread hadn't been staretd fixed
3. setting font for radiobox now works immediately (you had to invalidate
   the window manually, e.g. by covering it with another one, before)
4. added and documented wxConstCast() and wxStaticCast()
5. attempts to make wxFontEnumeraotr::EnumEncodings() work under MSW
