How to stop getting cursor position?

I have a function based on GUI_27 by Matt Fig. The function continuously displays the position of the cursor as the mouse is moved within the axis. I'd like to know: how can I turn off this behavior, so it stops extracting and displaying the cursor location? In my real GUI, the user pushes a pushbutton to start displaying the cursor location, but I don't know how to stop it.

KAE - how have you implemented the function as described in GUI_27? Do you use the same callback like

 set(S.fh,'windowbuttonmotionfcn',{@fh_wbmfcn,S}) % Set the motion detector

If so, you could try clearing this callback as

 set(S.fh,'windowbuttonmotionfcn',[]);

so that the WindowButtonMotionFcn no longer has a callback function to update the cursor position. When you need to know the cursor position then just restore the callback as however you have initialed it before.

This will work with how I have the code implemented, thanks!
