realize is called when the dialog is first created.
map is called each time show() is called.
I believe the widget.show() method generates a map-event which
generates a map signal. You can see that if you connect both 'map' and
'map-event' to the dialog.
I use the map signal, not map-event, for dialogs to populate
themselves then use this function instead of widget.show():
def showDialog(self, dialogName, title = None):
d = self.wtree.get_widget(dialogName)
if title:
d.set_title(title)
if d.flags(gtk.MAPPED) == 0:
d.show()
else:
d.get_window()._raise()
# call map again so dialogs will refresh their contents
return d.emit('map', d)
