Redraw OpenGL window at 60 fps (Vsync On)

[FOSS Dev]

Hi i am new to FLTK but i want to know how can i make a render loop that automatically redraw OpenGL window at a constant frame rate.

Thanks

#include <FL/Fl_Gl_Window.H>
#include <FL/Fl.H>

Fl_Gl_Window *my_gl_window = ....

my_gl_window->show();

while (1) {
  Fl::wait(1./60); // that would give 60 redraws per second
  my_gl_window->redraw();
  }

I think, if I were doing it like this, I might look at using the
Fl::add_timeout() mechanism to trigger the redraw of the GL window
(though I'm certain Manolo knows that!)
