I now have a need to hide() a Fl_Gl_Window and then later show() it again.
The documentation appears to say that the OpenGL context is destroyed when the Fl_Gl_Window is hide()'ed.
When I try to show() the Fl_Gl_Window, I get a segfault in my draw() code that is called from Fl_Gl_Window::flush().
I think it is because I have not re-established the OpenGL context that was destroyed during the hide().
What kind of special care needs to be taken to be able to hide() / show() a Fl_Gl_Window?
Thanks for any help,
Rob
