A left and right panel.The left panel has two buttons. The right panel has onestatic text. The buttons change the number displayed in thestatic text. The question is, how do we grab the reference tothe static text?If all the widgets are within one class, it is trivial. But whatif those widgets are created in different classes? In suchsituations, we must get the reference via the hierarchy.panel = wx.Panel(self, -1)self.rightPanel = RightPanel(panel, -1)leftPanel = LeftPanel(panel, -1)Notice that the right panel must be defined before the leftpanel. It is because during the construction of the left panel,we are looking for the static text widget, which is defined in7 de 8 27/04/2008 1:01
