I'm not aware of any convention for trailing underscores other than
the one described in PEP8.

If you use a different name in the subclass then whatever code calls
the method will continue to call the base class version instead of
your subclassed version.  Is there a reason you don't just use super()
to chain the call to the base method?

    def OnLeftDClick(self, event):
        event.Skip()
        super(MyClassName, self).OnLeftDClick(event)
