Debugging ActiveX Control Events in wxPython/PythonWin

[Charles Medcoff]

I am attemping to create a window (wxWindow) that hosts an ActiveX
control.  I have not had any problems getting through the
window/control creation process but my control subclass event handlers
are never called.  I've stepped (debugged) all the way thought wxPython
and into the Control.HookOleEvent() method in the PythonWin activeX.py
module. I have observed the successful search for event handler methods
in my subclass.  Where do I go from here to debug the problem?  Here is
the code

##import win32com.client
from wxPython.wx import *

g_rslinx = None

if wxPlatform == '__WXMSW__':
    from wxPython.lib.activexwrapper import MakeActiveXClass
    import win32com.client.gencache

    try:
        rsWhoLibModule = win32com.client.gencache.EnsureModule
('{172C823C-7624-11D0-A1BF-0060B01A661C}', 0, 1, 0)
    except:
        raise ImportError("Can't load RSWho Type Library")

# Class for event handling
class PyRsWho(wxWindow):
    def OnEnter(self, Selection):
        print "OnEnter"
    def OnSelChanged(self, Selection):
        print "OnSelChangled"
    def OnClientMenuItemSelected(self, Path, MenuID):
        print "OnClientMenuItemSelected(self, Path, MenuID):"
    def OnRightClick(self, Path, ClientMenu):
        print "OnRightClick(self, Path, ClientMenu):"
    def OnDoubleClick(self, Selection):
        print "OnDoubleClick(self, Selection):"

class App(wxApp):
    def OnInit(self):
        self.frame = wxFrame(NULL, -1, "Py RsPath", wxPoint(200,200),
wxSize(400,400))
        self.frame.Show(true)
        self.SetTopWindow(self.frame)

        rsWhoClass = MakeActiveXClass(rsWhoLibModule.RSWho, PyRsWho)
        self.rsWho = rsWhoClass(self.frame, -1, wxPoint(0,0),
self.frame.GetClientSize())
        return 1


app = App(0)
app.MainLoop()


I know the control works becase I've hosted it in C++ and VB.  I've
written nearly identical python code for hosting another control and
have had no problems there.  Suggestions?

Regards,
Chuck
