[gtkmm] lookup_widget in glademm

[Silviu D Minut <minutsil cse msu edu>]

In building GUIs with glade in C there was this lookup_widget() function
that did the obvious, defined in support.c. In glade-2 with glade-- there
is a window1_glade.hh which defines the main window of the application
(derived from Window). All the widgets contained in the main window
are pointers - only defined locally in the constructor, hence not visible
outside the constructor (e.g. in a callback). Is there a loolup_widget()
analog for glade-- ?

Thanks!
