show is a pseudo-event, it doesn't affect anything real.
no, expose events are sent whenever some part of the window needs to
be redrawn. thats quite different.

by contrast, expose_event is emitted for any necessary redraw.
you generally don't need map_event - its useful for obscure hacks

no. it is emitted once per mapping-onto-screen. this
mapping-onto-screen occurs after it has been realized+shown, and then
might
So to put it in plain words what you said was that map_event is emittted
if the window was first minimized and then brought back to the screen.
Right?
its hard to explain this to you without getting into a lot of X Window
concepts. what you have to keep in mind is that a window is a software

Thank you. So if I want to understand the deeper functions and events
of GTK, I need to study how the GTK API was created from the X Window
functions, right?
you will get a deeper appreciation, if only because there are
relatively complete docs on X available. however, GTK does not rely on

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.
