hi all;
strange !!!!
i got answer to the problem posted by me only.
now I have very good control of CANoe tool from python....
if anybody faces any problem wrt automation of CANoe tool using
python; do contact me.
here actual problem lied in analysing and implementing com heirarchy.
( which is really bit cumbersome)
onChange event is associated with App_Event.Environment.GetVariable
("dummy") object.
So we need to associate separate class with this object and then write
onChange function:
class evtClass:
def __init__(self):
print "initializing event class"
def OnChange(self,value):
print "value of environment variable changing"
print "changed value of environment variable is"
print value
see = App_Event.Environment.GetVariable("dummy")
see_temp=DispatchWithEvents(see,evtClass)
this will solve problem.
So we need to create separate classes for events associated with
separate objects.

sirjee
