Using waitfor for non Handle Graphics Object

Hi,

I'm trying to implement a code which should wait for timer timeout or change of a specific value befor futher code's execution. I've found the following code on the web. It's exactly what I'm looking for but it doesn't work with simple matlab handle object. Do someone know what to do?

% Wait for data updates to complete (isDone = false if timeout, true if data ok)
function isDone = waitForDone(object,timeout)
    % Initialize: timeout flag = false
    object.setDone(false);

      % Create and start the separate timeout timer thread
      hTimer = timer('TimerFcn',@(h,e)object.setDone(true), 'StartDelay',timeout);
      start(hTimer);

      % Wait for the object property to change or for timeout, whichever comes first
      waitfor(object,'Done',true);

      % waitfor is over - either because of timeout or because the data changed
      % To determine which, check whether the timer callback was activated
      isDone = (hTimer.TasksExecuted == 0);

      % Delete the time object
      try stop(hTimer);   catch, end
      try delete(hTimer); catch, end

      % Return the flag indicating whether or not timeout was reached
  end  % waitForDone

thanks for your support!
