I create a class for each window in the program.
The class has a method called load_glade()
that calls libglade.GladeXML
and contains a list of widgets I want to access:
e.g., widget_list = ('scrolledwindow', 'last')
that correspond to their Glade names
then I do:
for w in widget_list:
setattr(self, w, self.loader.get_widget(w))
So that the class member functions can access those widgets as:
self.scrolledwindow
and
self.last
I then have a signal handler dict like:
signal_handlers = {
'on_scores_select_row': self.on_scores_select_row,
'on_update_clicked': self.on_update_clicked,
'on_exit_clicked': self.on_exit_clicked,
}
self.loader.signal_autoconnect(signal_handlers)
so each callback is a member of the class.
I haven't run into any situations yet where this design strategy didn't
work well for me.
I have a student who is working on a junior/senior project that
involves parsing the glade XML file and create a class that does all
this (grabs the widget_list entries based on the names in the XML
file, sets up the signal_handlers dict, etc.) and makes empty signal
handlers. I know something exists to do this (gladepyc or something
like that), but it didn't seem to work very well when I tried it.
HTH,
Dave
