Multiple inheritance with Python

[CEXT-Dan]

Using PaletteWithDocReactor as an example. Why can't I do something like

class PalettePanel(wx.Panel,Ap.DocManagerReactor):
    def __init__(self):
        super().__init__()
        Ap.DocManagerReactor.__init__(self)
        self.reactor.addReactor()
        self.Bind(wx.EVT_SHOW, self.OnShow)

error

PyErr metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases ,Traceback -

You need to create a new metaclass that inherits from the metaclass of class A and the metaclass of class B.

class ABMeta(type(A), type(B)):
    pass

class C(A, B, metaclass=ABMeta):
    ...

If something doesn't work properly, it means that you need to implement some code in the metaclass body.

Ok, I’m thinking about ways I can wrap CAcFdUiFieldDialogHook & CAcFdUiFieldOptionDialog into a single wxPanel. I may have to have the event hook as a separate class
