This code does not always work as expected. This is due to the
new_window_state and changed_mask possibly having more than one flag
attached. The event.new_window_state and event.changed_mask are
enumerated data types.
Here is an example of the event.new_window_state passed to the callback
function: (actual debug print of event.new_window_state)
<flags GDK_WINDOW_STATE_ICONIFIED | GDK_WINDOW_STATE_MAXIMIZED of type
GdkWindowState>
So far I have not found out how to properly look for a specific flag
when there are more than one. I have found this doc
http://www.python.org/workshops/1994-11/BuiltInClasses/BuiltInClasses_5.html
which describes how to integrate CType structures into python. It is seems too
terse for my understanding though.
I have got some code working (so far) using the change_mask which so far
is only passing one flag, but in the docs it states that it too can have
combinations of flags.

working code:
def new_window_state(self, widget, event):
"""set the minimized variable to change the title to the same as the
statusbar text"""
dprint(event.new_window_state) # debug print statements
dprint(event.changed_mask)
if event.changed_mask == gtk.gdk.WINDOW_STATE_ICONIFIED:
if not self.minimized:
dprint("TERMINAL: new_window_state; event = minimized")
self.minimized = True
self.window.set_title(self.status_text)
else: # self.minimized:
dprint("TERMINAL: new_window_state; event = unminimized")
self.minimized = False
self.window.set_title(self.title)
return False
A potential problem with this code is if the self.minimized variable
gets out of sync with the actual window state.
Anyone know how to do correctly?
