@anchor{XREFscatterbusyaction}
@prindex scatter busyaction
@item @code{busyaction}: @qcode{"cancel"} | @{@qcode{"queue"}@}
Define how Octave handles the execution of this object's callback properties when it is unable to interrupt another object's executing callback.  This is only relevant when the currently executing callback object has its @code{interruptible} property set to @qcode{"off"}.  The @code{busyaction} property of the interrupting callback object indicates whether the interrupting callback is queued (@qcode{"queue"} (default)) or discarded (@qcode{"cancel"}).

@anchor{XREFscatterinterruptible}
@prindex scatter interruptible
@item @code{interruptible}: @qcode{"off"} | @{@qcode{"on"}@}
Specify whether this object's callback functions may be interrupted by other callbacks.  By default @code{interruptible} is @qcode{"on"} and callbacks that make use of @code{drawnow}, @code{figure}, @code{waitfor}, @code{getframe} or @code{pause} functions are eventually interrupted.
