Currently, some parts of the proprietary implementation of Cafu OS-specific code come with several problems: - Current use of DirectX7 under Windows for mouse input - prevents successful linking under 64-bit Windows, - doesn't work with touch or pen tablet input, - is worse(!) in performance than using the Win32 message queue (see below for reference). - Has no support for Mac OS X yet.
Modifying Cafu to employ the wxWidgets library (just like the editor CaWE) for display, main window and event handling would resolve these problems, plus yield (or at least make available for future use) all the other benefits of wxWidgets as well.
Regarding mouse input accuracy and performance, ''not'' using DirectInput seems to be favorable as well, see [http://msdn.microsoft.com/en-us/library/ee418864.aspx Taking Advantage of High-Definition Mouse Movement] for details. So nothing is lost by replacing DirectInput under Windows, and if the need arises, it can still be re-added besides wxWidgets later.
This ticket is a (recommended) prerequisite for ticket #19.
