Mouse.DirectlyOver在WPF中返回错误的UIElement [英] Mouse.DirectlyOver returns the wrong UIElement in WPF

问题描述

大家好，

虽然我尝试将鼠标悬停在标签"元素，  Mouse.DirectlyOver，它返回"TextBlock".因此.为什么会这样?

      private void Dynamic_Design_PreviewMouseMove(对象发送方，MouseEventArgs e)
        {
            if(e.LeftButton == MouseButtonState.Pressed)
            {
                  var uiElement = Mouse.DirectlyOver as UIElement;
            }
        }
对此有任何想法吗??


谢谢，

Hi All,

While i try to mouse over on the "Label" element , Mouse.DirectlyOver it returns the "TextBlock" as a result. Why it happen like this?

     private void Dynamic_Design_PreviewMouseMove(object sender, MouseEventArgs e)
        {
            if(e.LeftButton == MouseButtonState.Pressed)
            {
                 var uiElement = Mouse.DirectlyOver as UIElement;
            }
        }
Any idea on this..?


Thanks,
Sowndaiyan

推荐答案

标签几乎是TextBlock的包装，它解释了为什么返回TextBlock.

A label is pretty much a wrapper for a TextBlock which explains why you have TextBlock returned.
