Yeah, that's a good point. In that case, that code really doesn't belong in the Class1 __init__ method, as it depends on the whole hierarchy having already been properly initialized. Instead, I suggest using the wx.CallAfter function to schedule that code for when the event loop has actually been started. For example: class Class1(wx.Panel): def __init__(self, parent, id = -1, dpi = None, **kwargs): # Do all your initialization stuff. Then: wx.CallAfter(self._init_graph_panel) def _init_graph_panel(self): wx.GetApp().frame.graph_panel.plot([1,2,3,4,5],[3,4,3,4,3]) wx.GetApp().frame.graph_panel.figure.canvas.draw() By the way, looking at your object hierarchy more closely, isn't "app.frame.graph_panel" going to end up being the same thing as just "self.figure"? Why not just use the latter and remove the reliance on finding the correct frame? Cheers, Ian -- http://mail.python.org/mailman/listinfo/python-list
