Hey Cesar
nice idea
in recent hours i found a way in one module that is like your idea but with
list:
callbacks = []
def do_something():
print "anything"
def main():
global callbacks
idx = OpenMaya.MEventMessage.addEventCallback("timeChanged", get_sec)
callbacks.append(idx)
def remove_callbacks():
for call in callbacks:
OpenMaya.MMessage.removeCallback(call)
it works fine for me
thanks man
thanks to marcus
