you should not be using 'active' in this case: 'active' has a very
precise meaning in gtk+ (see gtk_widget_activate()).

a widget that is not on screen will not receive the expose event, and it
will not be drawn (otherwise you'd have to draw every single widget,
even hidden ones).

with gtk+ 2.14 you can use gtk_widget_get_snapshot() to retrieve a
GdkPixmap of any widget - including obscured ones. read the
documentation.

before gtk+ 2.14 you can't really do anything to obtain a snapshot of a
partially onscreen or obscured widget.
