Handle Validity Versus Handle Visibility

All handles remain valid regardless of whether they are visible or not. If you know an object's handle, you can set and get its properties. By default, figure handles are integers that are displayed at the top of the window.

You can provide further protection to figures by setting the IntegerHandle property to off. MATLAB then uses a floating-point number for figure handles.
