评论： KAE 2017-6-23

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.
