well if anyone cares in the end I used the following for my
ProgressBar, the problem is now in setPos as the skeleton
only seems to have 'pos' in [0,1]. Incidentally is there now any
real reason to keep the defaults separate from their clients?



#proxy class
class ProgressBar(Component):
        state = {
                'text': 'ProgressBar',
                'x': 0,
                'y': 0,
                'width': 100,
                'height': 15,
                'hmove': 0,
                'vmove': 0,
                'hstretch': 0,
                'vstretch': 0,
                'visible': 1,
                'enabled': 1,
                'pos': 0.,
                }
        def setPos(self,pos):
                assert 0<=pos<=1, "pos not in range"
                self.state['pos'] = pos
                self.wrapper.setPos(pos)

        def wrapperFactory(self):
                return backendModule().ProgressBarWrapper(self)


#dwgui implementation (should be easy in msw as well)
class ProgressBarWrapper(ComponentWrapper):
        _wndclass = "msctls_progress32"
        _win_style = WS_VISIBLE | WS_CHILD | PBS_SMOOTH

        def setPos(self,pos):
                if self.noWidget(): return
                #I tried to set range only once, but it didn't work
                user32.SendMessage(self.widget, PBM_SETRANGE, 0, 0xffff0000)
                return user32.SendMessage(self.widget, PBM_SETPOS, int(pos*0xffff), 0)
