Basically I have several buttons that all have the same callback. All
the buttons require the same action except two for which some extra
stuff is required. 

I know I could write a seperate callback for those two but I thought
that since the extra stuff was minor I would just use one function -
laziness :)   

Anyway, in the end I got round it by using glade_get_widget_name() to
get the name of the button (that is the name of the element in the UI
file) and then take action depending on the name. 

I think this is cleaner than attaching data to an element (via
g_object_set_data()) by hand as I was doing before using libglade.
