按钮上的发光效果 [英] Glow Effect on Buttons

问题描述

当我将鼠标悬停在按钮上时，我希望有一个发光效果，所以我知道鼠标正在盘旋。当鼠标不再悬停在按钮上时，我希望删除发光效果。

When I hover over a button I would like to have a glow effect in place, so I know that the mouse is hovering. When the mouse is not hovering over the button anymore, I would like to have the glow effect removed.

推荐答案

您好，

按钮控件具有Mouse_Hover（）事件功能。所以你可以在那个事件下编写代码。希望这会对你有所帮助。

Button control has Mouse_Hover() event functionality. So you could write code under that event. Hope this helps you.
