看看 wxPython 的 demo:

类似：

class MyEvtHandler(ogl.ShapeEvtHandler):
    ...
    def OnMovePost(self, dc, x, y, oldX, oldY, display):
        ogl.ShapeEvtHandler.OnMovePost(self, dc, x, y, oldX, oldY, display)
        self.UpdateStatusBar(self.GetShape())

OGL 在 Python 2.5.5以后就不是Official的组件了。好像也没人维护了。是不是考虑找别的Module替代？
