I usually use something like (pseudo-code!):

class MyFrame(wxFrame):
    def __init__(self, parent, id):
        wxFrame.__init__(...)
        ...create menu...
        EVT_MENU(self, ID_SAVE, self.Save)
        self.grid = MyGrid(...)
    def Save(self, event):
        # now here you can access the MyGrid instance
        # through self.grid.

I'm not exactly a wxPython expert, so maybe there are
better ways to do it. But this works for me.
