I am sorry, i don't understand
i have a container which has a button in it.
i can put instead in the container another container which 
contains the button itself but how could i draw into the container ?

Perhaps you mean that if i put something into the button with
gtk_container_add, this will be displayed on top of the widget ? 
I doubt it. The widget added inside the button would need to
be a windowless widget which draw things on its parent window
(like the label widget) but i doubt there is such a widget...

again, what do you mean, could you be more precise ?
