wxPython GetMDIParentFrame

Continued from Previous Post:

class MyChildFrame(wx.aui.AuiMDIChildFrame):
  def __init__(self, parent, count):
    wx.aui.AuiMDIChildFrame.__init__(self, parent, -1, title='Child %d'%count)
  def GetMDIParentFrame(self):
    # FIXME
    # wx.aui.AuiMDIChildFrame::GetParent returns
    # AuiMDIChildFrame not MyChildFrame
    return self.GetParent().GetParent()

I don't like this fix though, I do not have an alternative idea.

If it is in C++, I cast a MyChildFrame instance into an AuiMDIChildFrame instance in the GetMDIParentFrame method.
