Re: GTK+ Draw a Rectangle over other widgets?

["Matt Hoosier" <mwhoosier gmail com>]

Because some Gtk+ widgets use their own X11 windows while others
render themselves into a parent widget's X11 window, this may be a
harder job than you think. The most consistent solution might be to
allocate another X11 window (perhaps in pop-up mode, so suppress
window decorations), manually position it to occupy the area of the
rectangle you wish to draw, then draw the rectangle in this new
window.

There are a couple of mechanisms you might use to get this second X11
window: a GtkWindow in GTK_WINDOW_POPUP mode, or a dedicated GdkWindow
[probably allocated during a custom realize() method] belonging to
your container, which is rendered as the last step of an
"expose-event" handler executing in run-last position.
