Hello NG, this may seem a stupid (or even impossible) question, but my knowlegde of Python is quite limited. I have basically a simple graphical user interface that contains a Panel, another panel (child of the main panel) and a custom widget (child of the main panel). Basically is something like (only some small code, is in wxPython but the question is more Python-related):
class MainClass(wx.Panel): def __init__(self, *args, **kwds): wx.Panel.__init__(self, *args, **kwds) self.childpanel = wx.Panel(self, -1) self.customwidget = Custom(self, -1) layoutsizer = wx.BoxSizer(wx.VERTICAL) layoutsizer.Add(self.childpanel, 1) layoutsizer.Add(self.customwidget) layoutsizer.Layout() The class "Custom" has a lot of methods (functions), but the user won't call directly this class, he/she will call the MainClass class to construct the GUI app. However, all the methods that the user can call refer to the "Custom" class, not the MainClass class. That is, the methods that the user call should propagate to the "Custom" class. However, I know I can do: # Inside MainClass def SomeMethod(self, param): self.customwidget.SomeMethod(param) But the "Custom" class has *a lot* of methods, so I will end up in rewriting all the "SomeMethods" in the MainClass just to pass the parameters/settings to self.customwidget. Moreover, I know I can do (in the __init__ method of MainClass): def __init__(self, *args, **kwds): wx.Panel.__init__(self, *args, **kwds) Custom.__init__(self, parent, -1) In order to make MainClass knowing about the Custom methods. But the I will not be able (I suppose) to add self.customwidget to a layoutsizer. How can I write: layoutsizer = wx.BoxSizer(wx.VERTICAL) layoutsizer.Add(self.childpanel, 1) layoutsizer.Add(self) # <=== That's impossible layoutsizer.Layout() ? So (and I am very sorry for the long and maybe complex to understand post, english is not my mother tongue and I am still trying to figure out how to solve this problem), how can I let MainClass knowing about the Custom methods without rewriting all the Custom functions inside MainClass and then pass the parameters to Custom? Is there a way to "propagate" the methods to the child class (Custom)? Thanks for every suggestion, and sorry for the long post.
