Animiertes Gif unter GTK

[netnobbi]

Hi, I have a problem with keeping an animated gif running while the gtk main loop is blocked.
The gif (called waitImage) is placed on a GtkDialog (waitDialog). The GdkPixbufAnimation "behind" waitImage is called waitImageAnimated.
I tried to do it like this:

while(...) {
  gtk_widget_queue_draw(GTK_WIDGET (GTK_DIALOG (waitDlg)->vbox));
  gdk_window_process_updates (gtk_widget_get_parent_window (GTK_DIALOG
                                              (waitDlg)->vbox), true);
  waitImagePixbuf = gdk_pixbuf_animation_iter_get_pixbuf(
                  gdk_pixbuf_animation_get_iter(waitImageAnimated, NULL));
  gtk_image_set_from_pixbuf(GTK_IMAGE (waitImage),waitImagePixbuf);
}

But this doesn't work. The gif doesn't run.
Does anybody know, how to do it correctly?
A solution without memory leaks would be especially nice

Thank you, dasaspock

Ok: Ich hab's.
So funktionierts:

GdkPixbufAnimationIter *animIter = gdk_pixbuf_animation_get_iter(waitImageAnimated, 
                                   NULL);
while(WaitForSingleObject(hHomeThread,100) == WAIT_TIMEOUT) {
	gtk_widget_queue_draw(GTK_WIDGET (GTK_DIALOG (waitDlg)->vbox));
	gdk_window_process_updates (gtk_widget_get_parent_window (GTK_DIALOG 
                                    (waitDlg)->vbox), true);
	gdk_pixbuf_animation_iter_advance (animIter,NULL);
	waitImagePixbuf = gdk_pixbuf_animation_iter_get_pixbuf(animIter);
	gtk_image_set_from_pixbuf(GTK_IMAGE (waitImage),waitImagePixbuf);
}
g_object_unref(G_OBJECT(animIter));
