Detailed Description

This interface is the callback interface used by the drop target object to provide notification of Drag and Drop operations that involve the subject drop target.

Methods of this interface may be implemented to provide "drag under" visual feedback to the user throughout the Drag and Drop operation.

Member Function Documentation

dragEnter()

void dragEnter

(

[in] DropTargetDragEnterEvent

dtdee

)

Called when a drag operation has encountered the drop target.

Parameters

dtdee

The DropTargetDragEvent.

dragExit()

void dragExit

(

[in] DropTargetEvent

dte

)

The drag operation has departed the drop target without dropping.

Parameters

dte	The DropTargetEvent.

dragOver()

void dragOver

(

[in] DropTargetDragEvent

dtde

)

Called when a drag operation is ongoing on the drop target.

Parameters

dtde	The DropTargetEvent.

drop()

void drop

(

[in] DropTargetDropEvent

dtde

)

The drag operation has terminated with a drop on this drop target.

NOTE: The implementation has to wait until the method XDropTargetDropContext::dropComplete() is called before releasing the data for the drop operation. This should occur before returning from drop in a normal flow of operation. Also, the implementor of XDropTargetListener should not assume the DropTargetDropEvent to be meaningful after returning from the XDropTargetListener::drop() method.

Parameters

dtde	The DropTargetDropEvent.

dropActionChanged()

void dropActionChanged

(

[in] DropTargetDragEvent

dtde

)

Called when the user has modified the drop gesture.

Parameters

dtde	The DropTargetEvent.
