I need to show an icon on mouseEnter and hide the same on mouseLeave in the tree node. When I scroll using mouse wheel (on Windows) inside the tree view, the tree view scrolls keeping the mouse at the same position while the tree scrolls behind the mouse pointer, practically making the mouse enter and leave nodes. However, I don’t get any mouseEnter or mouseLeave message.
Is there a way to handle this? Or can it be considered as a bug in InDesign?
