Canceling events from COM Objects

[Oliver Nelson]

I have MapPoint working in Python, and I'm trying to cancel events on
the map, but I can't seem to make that happen. I'm responding to the
events successfully in my panel object. My code is like this:

global MapPointMod
MapPointMod =
win32com.client.gencache.EnsureModule("{51C0A9CA-F7B7-4F5A-96F4-43927C6FA50F}",
0, 1, 0)

class MyPanel(wx.Panel):
def __init__(self, *args, **kwds):
# begin wxGlade: MyPanel.__init__
kwds["style"] = wx.TAB_TRAVERSAL
wx.Panel.__init__(self, *args, **kwds)
self.frame = args[0]

MyMap = MakeActiveXClass(MapPointMod.MappointControl,
eventObj=self)
self.window_1 = MyMap(self, -1)
self.window_1.OpenMap("C:\\TEMP\\GPS_ON.ptt")
....
....
def OnBeforeClick(self, Button, Shift, X, Y, Cancel):
print "tada"
My event fires just fine, but I can't seem to figure out how to cancel
the event so that mappoint doesn't do its stuff with it...I've tried
setting Cancel based on the mappoint specs, but it doesn't seem to get
sent back anywhere...

Any ideas please?

Thanx,
