wxWindows. What is it?

wxWindows is perhaps the ultimate open source, cross platform GUI C/C++, development library there is.

It currently supports Win32, Gtk and Motif on Unix (many flavors including Linux, HPUX, DecAlpha, Sun Solaris, AIX), MAC OS10. Ports are in development including QT, BeOS, FreeBSD, Windows CE, and of course, OS/2.

I have been working on wxOS2 for about 3 years now, part time, at night and on the weekends. It is about 2/3rds done. SciTech currently is using it as a foundation for their eventual OS/2 port of wxMGL and will probably eventually take over all work on wxOS2. As it sits the GUI framework is pretty complete and I am working on the GDI (Gpi), mostly bitmap processing and such. Still need to add the more exotic controls and toolbars (already has a Windows style status bar).

WxWindows is not only a GUI toolkit, but basically the kitchen sink including full support for multithreading, full Unicode support including font encoding, TCPIP sockets, full featured stl-like container support without needing stl.

With wxOS2 reaching a near usable state developers can truly code once and compile to target platforms. I already do this for Linux and Windows and it REALLY WORKS! While support VisualAge 3.0 Fixpack 8, SciTech folks have built it using Watcom's latest open source compiler and EMX and VisualAge 3.6. VA4.0 is NOT supported although at one time I did have version that built using it. Maybe some other developers could come online and help finish the thing up.
