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.)
