如何在UIElement下获取按钮 [英] How to get the button under a UIElement

问题描述

我想在鼠标下找到按钮，但是它上面还有另一个UIElement.在我的表单中，它是一个矩形，我需要它，因此无法将其删除.

我可以像这样在鼠标下获得第一个UIElement:

I want to get the button under mouse, but there is another UIElement above it. In my form it''s a Rectangle,I need it,so it couldn''t be remove.

I can just get the first UIElement under mouse like this:

UIElement MyButton = GetElementUnderMouse<UIElement>();
public static T FindVisualParent<T>(UIElement element) where T : UIElement
{
    UIElement parent = element;
 
    while (parent != null)
    {
        var correctlyTyped = parent as T;
        if (correctlyTyped != null)
        {
            return correctlyTyped;
        }
        parent = VisualTreeHelper.GetParent(parent) as UIElement;
    }

    return null;
}

public static T GetElementUnderMouse<T>() where T : UIElement
{
    return FindVisualParent<T>(Mouse.DirectlyOver as UIElement);
}

推荐答案

您要达到什么目的?

如果要处理显示和隐藏按钮，则可以使用以下代码

what are u trying to achieve?

if its to deal with showing and hiding the button u may use below code

button1.Visibility = Visibility.Hidden;// to hide,just as if its under
button1.Visibility = Visibility.Visible;//to show it

如果您想隐藏隐藏按钮的属性，则
鼠标悬停在

if u wanna get the properties of the button with itself hidden then
on mouse over

button1.Visibility = Visibility.Visible;
button1.Opacity=0;
