A quite "ugly" way of doing what you want. It worked for my in the past.

Suppose you have n-different pixmaps to cycle. Then where you are
currently putting your pixmap, put in its place an hbox, and then pack
all
of your pixmaps in this hbox. Then hide all of the pixmaps (but not the
hbox, of course) (with gtk_widget_show, gtk_widget_hide, etc...), and
only
show the first pixmap.
Connect the clicked signal of the button with a signal handler in which,
you hide the last pixmap, and then show the next one (again
gtk_widget_show, gtk_widget_hide).
Even you can make an animation with a gtk_timer_add (or
gtk_iddle_add)...
Hope it helps....
