Class providing easy integration of ActiveXControls into
|
||||
wxPython GUI environments. Pass an instantiated control class (one
|
||||
which inherits from pywin.mfc.activex.Control and a particular control
|
||||
class generated by gencache) in the argument "control". Alternatively,
|
||||
pass the instantiated control to the SetControl method to allow for
|
||||
specifying the win32 style, id, etceteras
|
||||
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 objects 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.)
