So you create an OpenGL window using functions from the operating system, and you use FLTK to stitch another window into or next to the OpenGL window? I am not clear how you get both to work together, in particular event delivery is a problem, just like you encounter. Do you have two event loops? The OpenGL one and the FLTK one? How did you create the OpenGL window exactly and when in the process? FLTK expects to receive ALL events from the operating system and then distributes those to the correct windows and widgets. Having a second even delivery systems makes it hard or impossible to know what event is delivered where. Have you considered using Fl_GL_Window in your application? This would make all the window layering and event delivery work correctly. A working and copilable source code file that exhibits the bug would be extremely helpful. - Matthias _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
