If you don’t know how to change mouse cursor in Windows 10, don’t worry at all. Changing mouse pointer size and color is easy if you follow this article.

ishghandle's undocumented input parameter – The built-in function ishghandle accepts a second input argument with the expected handle type. It’s based on the red devilish color of the Umbrella corp.

Setting the mouse pointer shape is normally achieved by modifying the figure’s Pointer property, which is fully documented. If the change has not taken effect, then right-click on the plot once again, and click Select Text Update Function, and select the new callback function you have created 5.

While undocumented Java code is needed for setting component-specific pointer shapes, figure-wide shapes can be set using pure-Matlab. getptr and setptr (%Matlabroot\toolbox\matlab\uitools\getptr.m and setptr.m) access the pointer shape for a figure moveptr (%Matlabroot\toolbox\shared\controllib\moveptr.m) moves the pointer across the screen overobj (%Matlabroot\toolbox\matlab\uitools\overobj.m) determines which figure component is currently beneath the pointer. All these files are pure-Matlab non-Java files, which can be edited and modified. Getptr, setptr, moveptr and overobj are all semi-documented functions (help section available, but online doc and official support not) which are used for internal Matlab purposes and relate to the mouse pointer. However, for some reason, some very-useful functions have remained undocumented and unsupported despite having a very long history (as far back as Matlab 6, a decade ago). Matlab contains several well-documented functions and properties dealing with the mouse pointer.
