function getNextEvent(obj, cb, statenow) %GETNEXTEVENT Add a callback to the next button-up event % % GETNEXTEVENT(OBJ, CB) adds a callback that will fire when the next % button-up event is captured by the object. It will then be discarded. % % GETNEXTEVENT(OBJ, CB, STATENOW) optionally specifies what the expected % current button state is: false for up, true for pressed. If the manager % thinks the button is up but the specified current state is down, % callbacks are immediately fired as this indicates an event ordering % problem that should not be allowed to happen. % Copyright 2000-2004 The MathWorks, Inc. and Ford Global Technologies, Inc. if isempty(obj.OneTimeCallbacks) obj.OneTimeCallbacks = {cb}; else obj.OneTimeCallbacks(end+1) = {cb}; end if (nargin>2 && statenow && ~obj.mouseButtonState); % Immediately flush events obj.pFireCallbacks; end
