IDropTarget interface (oleidl.h)
The IDropTarget interface is one of the interfaces you implement to provide drag-and-drop operations in your application. It contains methods used in any application that can be a target for data during a drag-and-drop operation. A drop-target application is responsible for:
- Determining the effect of the drop on the target application.
- Incorporating any valid dropped data when the drop occurs.
- Communicating target feedback to the source so the source application can provide appropriate visual feedback such as setting the cursor.
- Implementing drag scrolling.
- Registering and revoking its application windows as drop targets.
Inheritance
The IDropTarget interface inherits from the IUnknown interface. IDropTarget also has these types of members:
Methods
The IDropTarget interface has these methods.
| IDropTarget::DragEnter Indicates whether a drop can be accepted, and, if so, the effect of the drop. |
| IDropTarget::DragLeave Removes target feedback and releases the data object. |
| IDropTarget::DragOver Provides target feedback to the user and communicates the drop's effect to the DoDragDrop function so it can communicate the effect of the drop back to the source. |
| IDropTarget::Drop Incorporates the source data into the target window, removes target feedback, and releases the data object. |
