90 handler A callable object to be invoked when the event
91 is delivered to self. Pass None to disconnect an
92 event handler.
93
94 source Sometimes the event originates from a different window
95 than self, but you still want to catch it in self. (For
96 example, a button event delivered to a frame.) By
97 passing the source of the event, the event handling
98 system is able to differentiate between the same event
99 type from different controls.
