Thanks.

When wx windows are destroyed they do __dict__.clear(), so that would
get rid of the reference. And while window is live, a reference is OK
anyway.

Exactly, but relying on wx consistency can be risky. Also, who knows
what workarounds are in work on different platforms? I really hope at
least SetSize followed by an immediate GetClientSize works all of the
time.

Something is odd with them though. Following test prints "maintain" three times.

class Test(trellis.Component):
    @trellis.maintain
    def value(self):
        print 'maintain'

    @value.connector
    def _watch(self, sensor):
       pass

    @value.disconnector
    def _unwatch(self, sensor, key):
        pass


t = Test()
