WPF 4拖放与视觉元素作为光标 [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，我想启用拖放功能，目前我有一个基本的拖放实现，但我发现如果不是改变鼠标光标，它会好得多over 来表示移动操作，我可以在我的手指下使用一个图像.

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.

我的拖放操作是在自定义用户控件中启动的，因此我需要将可视元素插入可视树并让它跟随我的手指，也许我应该启用 ManipulationDelta我的主窗口上的事件，检查布尔值然后移动项目?

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?

推荐答案

有一个使用自定义拖动光标的例子 在 Jaime Rodriguez msdn 博客.您可以处理 GiveFeedback 事件并更改鼠标光标，但要使用自定义 Visual，作者创建一个新窗口并更新 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.
