So drawing area is my choice. I really need some dynamics.

Well. I understand. But is the return value of my_idle function the only
mechanism to stop calling it? Can I set some timer to call idle function one
time per call_period?

Yes this works. Thank you very much! This really helped. For now I can
program, but Are there better ways to do such drawings?
Just to understand what I am doing: The gdk_draw function used instead of
gtk_* because the drawing area is the X window. And so we need some X lib
functions (gdk wrapers) to draw on it. Am I right?
Thank you in advance,

P.S. Is this mailing list the right place for questions about gtk+
programming, or there are better lists to ask? Sorry If I was wrong.
