Q:

MONO GTK#: Event when a window is focused on

I am trying to get a ComboBox to update in Window 1, when I close Window2. 
Is there an easy way in how I can fire an event when Window 1 gets focused on again, so the combo updates?? 
Since the combo is in Window1, I cannot use the event when Window2 closes to update the Combo unless I make it public.

A:

You can use Gtk's FocusIn event to get notified when a window becomes focused.
