在 wpf 中获取窗口内元素的绝对位置 [英] Get Absolute Position of element within the window in wpf

问题描述

我想在双击时获取元素相对于窗口/根元素的绝对位置.元素在它的父元素中的相对位置是我所能达到的，而我想要达到的是相对于窗口的点.我已经看到了如何在屏幕上而不是在窗口中获取元素点的解决方案.

I would like to get the absolute position of an element in relation to the window/root element when it is double clicked. The element's relative position within it's parent is all I can seem to get to, and what I'm trying to get to is the point relative to the window. I've seen solutions of how to get a the point of an element on the screen, but not in the window.

推荐答案

我认为 BrandonS 想要的不是 mouse 相对于根元素的位置，而是某个后代元素的位置.

I think what BrandonS wants is not the position of the mouse relative to the root element, but rather the position of some descendant element.

为此，有 TransformToAncestor 方法:

Point relativePoint = myVisual.TransformToAncestor(rootVisual)
                              .Transform(new Point(0, 0));

其中 myVisual 是刚刚被双击的元素，而 rootVisual 是 Application.Current.MainWindow 或任何你想要的相对位置.

Where myVisual is the element that was just double-clicked, and rootVisual is Application.Current.MainWindow or whatever you want the position relative to.
