Use the same pushbutton in a GUI as Start and Pause button for an animated loop

I'm creating a GUI that starts an animation with a pushbutton. I want to:

- start the animation at the first button press - pause the animation at the second button press - resume the animation at the third button press

and so on...

I refresh my plot in the animation is by doing:

for ii:length(X)
     set('XData',...,'YData',...)
end

I know how to do this with 2 separate buttons:

function start_button_callback

if get(hObject,'value')
     for ii:length(X)
         if get(hObject,'value') %checks if changed by pause button
            set('XData',...,'YData',...)
            ....
         else
           break;
         end
     end
  end

    function pause_button_callback 
    if get(hObject,'Value')
        set(handles.start_button,'Value',0);
    end

What I want is to use a single pushbutton to start&pause&resume, but I can't get to interrupt the for loop when pushing the start button the second time, even when using a 'handles.counter'. The value of the counter isn't updated at every push button if the loop isn't finished. Any ideas?

Using toggle button instead of a push button would be better in this case.

You're right, it's more appropriate for my purpose, thanks!

Setting 'Interruptible' to 'off' is enough and works fine. I had understood this property the other way round. Thanks!

Did you insert a drawnow to give Matlab the chance to process events?

Did you set the 'Interruptible' property of the button to 'off'?
