实现IDropTarget

问题描述

我想将文件从Windows资源管理器拖放到我正在Codegear RAD studio 2009中构建的应用程序中。然后，我希望能够从拖放对象中访问数据。我相信我必须实现IDropTarget。有人可以提供一个我如何实现IDropTarget来实现这个的例子？

解决方案

有一个好的例子，由Michael Dunn在codeproject.com上编写，显示如何实现 IDropTarget ，并从拖放操作中用于存储数据的 IDataObject 内访问数据。

I would like to drag and drop files from windows explorer onto my application which is being built in Codegear RAD studio 2009. Then I would like to be able to access data from the object I am dragging and dropping. I believe I have to implement IDropTarget. Can someone please provide an example of how I might implement IDropTarget to achieve this?

解决方案

There is a nice example written by Michael Dunn over at codeproject.com which shows how to implement IDropTarget and access data from inside a IDataObject which is used to store data during the drag and drop operation.
