To create this callback automatically in GUIDE see picture below. For more information, type 'help simplot' at the MATLAB command window prompt. You can find some more information on mouse pointer modification in MATLAB here. This will generate a MATLAB figure that will allow you to change the figure properties.

This code was based on this post on UndocumentedMatlab. Please note that instead of an if, this could be a switch-case type of selection (in case you want your cursor to change differently for different UI elements).

Setptr(gcf, 'fleur') %//otherwise (re)change to default Setptr(gcf, 'hand') %// Change to this cursor if pointer is inside

For example see my attached code where I changed the 0,0,0 to 1,1,1 (white).
