Event Processing During Callback Execution
The following sequence describes how MATLAB processes events while a callback executes:
drawnow
, figure
, getframe
, pause
, or waitfor
command in the callback routine, MATLAB suspends execution and begins processing the event queue.
drawnow
, figure
, getframe
, pause
, or waitfor
command, MATLAB repeats these steps for the remaining events in the queue.
BusyAction
property of the object that generated the event.
BusyAction
is queue
, MATLAB leaves the event in the event queue.
BusyAction
is cancel
, MATLAB discards the event.
This process continues until the callback completes execution. When MATLAB returns the prompt to the command window, all events have been processed.
