You don't need ListControlMeta at all; just inherit from wx.Frame and (new-style) CopyAndPaste directly. > $ python -u ./failover_pickle_demo09.py > Traceback (most recent call last): > File "./failover_pickle_demo09.py", line 324, in <module> > class ListControlMeta(wx.Frame, CopyAndPaste): > TypeError: Error when calling the metaclass bases > metaclass conflict: the metaclass of a derived class must be a > (non-strict) subclass of the metaclasses of all its bases Are you sure you're executing the latest version where CopyAndPaste is a new-style class? The equivalent code works for me: >>> import wx >>> class CopyAndPaste(object): ... pass ... >>> class ListControl(wx.Frame, CopyAndPaste): ... pass ... >>> # no error Could it be that you're using an older version of wx, where wx.Frame itself is an old-style class? -- http://mail.python.org/mailman/listinfo/python-list
