MATLAB: Waiting for a Timer object to compelte a Task

timerwait

Hi,

I have a timer that runs indefinitely in background. It is incrementing a global variable, x, from 0.

Outside of the timer object, on the GUI, the user may press a button, resetting x to 0. I would like the user to wait (hang) until x > 10, at which point a message would pop up.

Is there a way for me to wait until the Timer object completes its task and check if x > 10 after each Timer task execution?

I basically want to wait for the timer to complete 10 times before I execute further code in the callback function the user triggered.

Thanks in advance.

Instead of using a global variable, use the UserData property of the timer object, and use waitfor() to wait until the UserData property has the value you want; see http://www.mathworks.com/help/techdoc/ref/waitfor.html

It is allowed for one handle graphics callback to interrupt another, provided that the Interruptible and BusyAction properties agree.

Note: waitbar() creates a new figure with its own properties.

MATLAB: How to get the timer object from within the timer’s callbacks, such as ‘TimerFcn’ and ‘StopFcn’

By default, the timer function callbacks pass the timer object as the first argument, and the event data associated with the callback as the second argument. Therefore, you always have access to the timer object from within its callback.

For more information and to see an example of how to define a timer callback, refer to the "Creating Callback Functions" section of the following URL:
