I'm not sure if I understand this correctly. What means "at the
end of my GL viewport widget"? Does this mean at the end of the
constructor?
I read that to mean he's calling Fl_Gl_Window::draw() and the
bottom of his widget's draw()
because he (probably) has FLTK widgets that are children of his
Fl_Gl_Window derived widget.
According to the docs, your draw() is supposed to do all the GL
stuff, then the last thing
you do before return()ing is to call Fl_Gl_Window::draw() so
that the child widgets can
be drawn over your opengl drawing.
