描述

Problem to solve

I am trying to implement some custom functionality in my program based off what element in the tree I am hovering over. While I can easily tell what item has been selected, I can not seem to find a way to determine what individual element is being hovered over.

Proposed solution

VTreeview has activated which is an array of ids of activated nodes. All that is needed is something like "hovered" which is an array of ids of hovered over node(s). This probably doesn't need to be an array and can just be a single element.

研究方向: Examine the VTreeview component source code to understand how the 'activated' prop is implemented. Then add a new 'hovered' prop that tracks the currently hovered node using mouseenter and mouseleave events. Update the TypeScript types and write unit tests for the new functionality.
