Hey, me too!; only we use glade under linux to generate
the xml and write our gtkrc's by hand. (only our objects
dont "drag" and cant be moved.)

If this really works; (to my great surprise) I would look
at gtkfixed.c and check out the "expose" event handlers.

gtk_container_add(GTK_CONTAINER(fixed), widget);

or consequently gtk_fixed_put(...)

will add the new widget to a GList * and then
refer to this GList * to draw the children
in the expose event handler.

Hmm; usually in gtk we call that "inside" as opposed to "on top"

You can have a button with a child label; but a label on top
of a button is another story.


Good luck!,
