            Bind an event to an event handler.

              event     One of the EVT_* objects that specifies the
                        type of event to bind,

              handler   A callable object to be invoked when the event
                        is delivered to self.  Pass None to disconnect an
                        event handler.

              source    Sometimes the event originates from a different window
                        than self, but you still want to catch it in self.  (For
                        example, a button event delivered to a frame.)  By
                        passing the source of the event, the event handling
                        system is able to differentiate between the same event
                        type from different controls.

              id,id2    Used for menu IDs or for event types that require a
                        range of IDs
