You can use _get_allocation() to get the size and position of a widget
within it's parent:

http://library.gnome.org/devel/gtk/stable/GtkWidget.html#gtk-widget-get-allocation

There's also a more general thing that will translate between any two
widgets which share a common ancestor:

http://library.gnome.org/devel/gtk/stable/GtkWidget.html#gtk-widget-translate-coordinates

If you're trying to turn mouse x/y into widget x/y, I think that
should be done for you, as far as I know.
