If "expose event" refers to window system expose events, as in "I, the window system, did not save a copy of the pixels 
behind this portion of your window when some other window was dragged on top of it or came to the front and covered it, 
and that portion of your window is now exposed, so you're going to have to draw it all over again", then whether thing 
work without expose event callbacks may depend on whether the window system saves those copies and redraws the exposed 
part of the window for you or doesn't save them and requires the application to do so.
