How to install animation

[Andreas Tille <tille physik uni-halle de>]

Hello,

I'm bussy writing an application which brings a set of images as
fast as possible onto the screen ... lets say a kind of animation.
My first try was a commandline driven version using gdk and gdk_imlib.
Now I want to add a GTK+ interface.  My problem is now, how to install
a routine which runs, say in the background of gtk_main() while
gtk_main() waits for user activities.  The animation should run
even if the user makes inputs in the interface window, exept the
user does something, which has influence to the animation, lets say
the stop button.

Is there any mechanism for this purpose?

Thanks in advance

     Andreas.
