def MakeActiveXClass(CoClass, eventClass=None, eventObj=None):
    """
    Dynamically construct a new class that derives from wxWindow, the
    ActiveX control and the appropriate COM classes.  This new class
    can be used just like the wxWindow class, but will also respond
    appropriately to the methods and properties of the COM object.  If
    this class, a derived class or a mix-in class has method names
    that match the COM object's event names, they will be called
    automatically.

    CoClass -- A COM control class from a module generated by
            makepy.py from a COM TypeLibrary.  Can also accept a
            CLSID.

    eventClass -- If given, this class will be added to the set of
            base classes that the new class is drived from.  It is
            good for mix-in classes for catching events.

    eventObj -- If given, this object will be searched for attributes
            by the new class's __getattr__ method, (like a mix-in
            object.)  This is useful if you want to catch COM
            callbacks in an existing object, (such as the parent
            window.)
