WPF 4拖放视觉元素作为光标 [英] WPF 4 Drag and Drop with visual element as cursor

问题描述

我有一个WPF 4应用程序，我想启用拖放使用，目前我有一个基本的拖放工作拖放实现，但是我发现，这将是如果更好，而不是鼠标光标改变在重新present移动操作，我可以用一个形象我的手指下面。

I have a WPF 4 app which I want to enable drag and drop with, currently I have it working with a basic drag and drop implementation, but I have found that it would be much better if, instead of the mouse cursor changing over to represent the move operation, I could use an image underneath my finger.

我似乎无法找到任何样品或DOCO具有此工作开箱即用，所以林假设我要去必须建立它的自定义...任何想法？

I cannot seem to find any samples or doco that has this working out of the box, so Im assuming Im going to have to build it custom... any ideas?

我拖放一个自定义用户控件内开始运作，所以我需要插入一个视觉元素插入可视化树，让它跟着我的手指周围，也许我应该让 ManipulationDelta 事件对我的主窗口中，选中一个布尔然后将项目周围？

My drag and drop operation is initiated inside a custom user control, so I will need to insert a visual element into the visual tree and have it follow my finger around, perhaps I should enable the ManipulationDelta event on my main window, check for a boolean then move the item around?

我只是抛出的想法，在这一点上各地，任何帮助或想法将不胜AP preciated。

Im just throwing ideas around at this point, any help or ideas would be greatly appreciated.

干杯， 马克

有使用自定义的拖动光标的在海梅·罗德里格斯MSDN博客。您可以处理的<一个href="http://msdn.microsoft.com/en-us/library/system.windows.uielement.givefeedback%28v=vs.85%29.aspx"相对=nofollow> GiveFeedback在 事件，改变鼠标光标，而是使用自定义视觉笔者创建了一个新的窗口和更新<一个位置href="http://msdn.microsoft.com/en-us/library/system.windows.uielement.querycontinuedrag%28v=vs.85%29.aspx"相对=nofollow> QueryContinueDrag 。

There is an example of using a custom drag cursor at Jaime Rodriguez msdn blog. You can handle the GiveFeedback event and change the mouse cursor, but to use a custom Visual the author creates a new Window and updates the position on QueryContinueDrag.
