I have already written a small GUI directly in WINAPI for my computational math project. Now I want to go for a more serious interface by adding an extra .cpp file. Ultimately, I want to have a canvas on which to draw straight lines and text, a resizable table to enter numbers (of size varying from 1x2 to at least 4x12) a few buttons, combo boxes and text fields.
I would love if the GUI kit can be used on other platforms (I have a friend to test the code on Macintosh). The main bulk of my code already compiles on Macintosh (my friend just excludes my .cpp GUI file from his project).
I finally found the moral strength to get a toolkit to a basic running position. My first try is with a toolkit named FOX toolkit. http://www.fox-toolkit.org/
It looks relatively simple to use - has anyone ever tried/used it?
The code is only 4.7MB (but the build time took quite some time on my excellent 256MB RAM 1Ghz machine).
