How can i change a GUI toggle state using values from a separate function?

I am creating a flight simulator GUI and I would like to change the state of a toggle switch based off of the status of a joystick button. If the joystick button is depressed (returns a value of '1'), I would like the toggle switch to also represent that state ('Value', 'Max'). How would I go about retrieving the joystick value within the toggle button call back function(tb1_Callback)? Any help would be greatly appreciated. Thanks!!

In hind sight this was a bit of a naive question and a little bit of playing around got me the desired result. I had to place the code within the 'while' loop which read in joystick data. In my case b7 corresponds with button 7 on the joystick.

 if (b7 == 1);
    set(handles.tb7, 'Value', 1);
    set(handles.tb7, 'BackgroundColor', 'y');
    else (b7 == 0); 
    set(handles.tb7, 'Value', 0);
    set(handles.tb7, 'BackgroundColor', [.94 .94 .94]);
    end

Hope this helps anyone facing a similar situation.
