custom events within classes

Hi, is it possible to register more than one function for listing on a custom event? When pressing the 'e'-button the following code should print out 'B' and 'C'. But only 'C' is printed out. When I swap the two *.enableEvent(EVENT) lines then 'B' is printed out.

Therefore I guess only one function can listen to an event at the same time. Am I right?

Code:

import viz



class A(object):

        def __init__(self):

                pass

        

        def enableEvent(self, EventID):

                viz.callback(EventID,self.doit)

                

        def doit(self):

                pass

                

class B(A):

        def __init__(self):

                pass

                

        def doit(self):

                print "B"

                

class C(A):

        def __init__(self):

                pass

                

        def doit(self):

                print "C"



viz.go()



EVENT = viz.getEventID('EVENT')



b = B()

b.enableEvent(EVENT)

c = C()

c.enableEvent(EVENT)





def sendEvent():

        viz.sendEvent(EVENT)



vizact.onkeydown('e',sendEvent)

Yes, have a look in the documentation under the Reference -> Events -> Event basics section. It contains sample code showing how to use the viz.EventClass for registering multiple objects with an event.

the vizact.onevent function is pritty handy for this too

Hm, could you illustrate it on my sample code please? I had a look on the event classes but I don't know how to process my own event in class A respectively B and C.

The vizact.onevent documentation is unfortunately to scarce.

Code:

class A(object):

        def __init__(self):

                pass

        

        def enableEvent(self, EventID):

                vizact.onevent(EventID, lambda : (True,None),self.doit)
