I need to get the curent radius and position of the circle using drawcircle() in GUIDE. Is there an example of how to add a callback? I'm not sure how to use the images.roi.CircleMovingEventData class
Thank you

h = drawcircle('Center', [500, 500], 'Radius', 100, 'StripeColor', 'red'); %adjust parameters as needed
L1 = addlistener(h, 'ROIMoved', @(hObject, event) disp(event.CurrentCenter)) %example callback
