WPF拖& Drop：如何直接拖动元素？ [英] WPF Drag & Drop: How to literally drag an element?

问题描述

说我有一个 ListBox 有些项目，并说我实现该列表的拖放功能。如果我想从该列表框中拖动一个项目，我该如何实际地移动拖动的项目？

我想实现将列表框项目放在鼠标光标下的效果，并可以在窗口中拖动时移动它。遵循这个示例，我得到的是基于的游标更改， DragDropEffects 枚举选项。

解决方案

这通常是使用adorner完成的。请参阅这里为例。

Say I have a ListBox with some items and say I implement drag and drop functionality for that list. If I want to drag an item from that list box, how can I actually move the dragged item?

I want to achieve the effect of having the list box item under my mouse cursor and to be able to move with it as I drag it on the window. By following this example, all I get is a cursor change based on the DragDropEffects enum choice.

解决方案

This is typically done using an adorner. See here for an example.
