its nothing to do with loops.

all GUI applications have this structure:

	main () {

		... do some setup ....
	
	        while (no_reason_to_exit) {

		    GUI_Toolkit_waits_for_events ();
	            GUI_Toolkit_calls_your_event_handlers ();
	            GUI_Toolkit_updates_windows();
	        }


		... do some shutdown stuff ...

	}

as you can hopefully see, nothing that you do inside any code you write
for an event handler (whether its a button press, or an idle handler or
whatever else) will be visible until the *next* iteration of the GUI
toolkit's "update windows" step.
