How to change mouse cursor with specific icons or widgets when the cursor enters a particular range


#1

Could someone who is proffesional teaches me how to replace the mouse cursor with an icon or a widget when the cursor enters a particular range.
I found a share which has the effect that I want, but I don’t have the tutorial or .rp file of it.
