you (GTK+) provide for me. I have been told that copywrite is free and

Yes you're right, I just meant to give the base idea.
..I think that gtk_widget_queue_draw_area() enqueues a redraw at the next
frame clock tick,

I should point out that the draw_func may be called by Gtk whenever it
needs,
The best is to have the timer callback change the "current" bitmap and call
gtk_widget_queue_draw_area().
Then on the drawing callback of the drawing area you just paint the
"current" bitmap.

I suggest you use GStreamer, you can build a video by pushing bitmap frames
and it does everything else for you.
Otherwise, you can animate a DrawingArea. Set up a 60hz timer on your own.
The timer callback simply calls
gtk_widget_queue_draw_area()

just a quick note: you don't get to control the refresh rate.
your screen update refresh rate is independent of GTK+. All modern GUI
