With libglade, if you specify an object... it is like reffering to prehistoric
gtk_signal_connect_object(), which swaps your instance/user-data arguments
free-of-charge, allowing for direct hooking up of function calls from
within Glade.

i.e. connect to button1 "clicked", specify "window1" as the object, and then
just put "gtk_widget_hide" as the callback... you just wrote a button that
closes the window without any code...

Yeah its a little awkard an unclear... just forget about it ;-)
