I’m not satisfied with GLUT’s menu system, but I don’t want to deal with the complexity of something like GTK and the GTK OpenGL extension. I also would prefer not to make my code operating system-dependent. Is there a nice middle ground solution to this? How much work would it be to provide an integrated drop-down menu system that acts like a windows toolbar, maybe as a transparent overlay in the viewport? Does anyone know of an open-source program that does something like this? I’m open to any suggestions for making menus within my programs. Thanks.
Try fltk from www.fltk.org. It’s really stable free software, and it’s cross platform. Version 1.1 is the stable version. 2.0 is more current but subject to changes since is still being developed.
The original GLUT came with mui but there are other and probably better alternatives. Here is one http://plib.sourceforge.net/pui/
