What are map_event and unmap_event?

[Jack Chen <jacks_small_world yahoo com>]

Hi, everyone

     My name is Jack. I am new to the list. My question is what the two
events, map_event and unmap_event, are. I saw them used with the
drawing_area widget but don't know what they are for, and the official
API reference didn't document them.

Thank you in advance for your help.

Jack
