Or continue to use -1 and then use one of these approaches:

* save the auto-generated ID using something like "self.btn1id = 
btn1.GetId()" and then test if the event id is equal to self.btn1id.

* just test it in the handler, like "if evt.GetId() == 
self.btn1.GetId():..."

* or you can get the object that sent the event with 
evt.GetEventObject() and test if it is the button object in question.
