Hi Everyone,

I need to recursively iterate through all the containers in a window to get to the widgets in the window, which are not containers.

I scanned the Gtk2hs docs and I could not find a good way to determine if a widget is a container or not.  I saw that the GObjectClass defines a isA function.  am I going in the right direction here or is there a better way to recurse through containers in Gtk2hs?
