FUI 3D

Blitz3D Forums/Blitz3D Programming/FUI 3D

I've just gotten said library working (strange errors before) and its pretty cool but I probably don't need all of it and I want to *understand* the things included in my programs. I'm locking at the code of window_resizable.bb and fui_3d.bb (main file, always included) and the .decls file but I can't figure out what exactly that enables resizable (and multiple, I suppose?) windows in Blitz3D.

Is it something with the Win API?
