Probably the best way to do this is to use notify::selected on the
source you're interested in. The 'selected' property is true when the
source is visible, false otherwise.

Since the source object is also the widget container, you could also
pack your widgets directly into the source and avoid the whole
problem, but that may bring other problems with it.
