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

void dragEnter ( [in] DropTargetDragEnterEvent  dtdee)

Called when a drag operation has encountered the drop target.

Parameters
dtdeeThe DropTargetDragEvent.
void dragExit ( [in] DropTargetEvent  dte)

The drag operation has departed the drop target without dropping.

Parameters
dteThe DropTargetEvent.
void dragOver ( [in] DropTargetDragEvent  dtde)

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

Parameters
dtdeThe DropTargetEvent.
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
dtdeThe DropTargetDropEvent.
void dropActionChanged ( [in] DropTargetDragEvent  dtde)

Called when the user has modified the drop gesture.

Parameters
dtdeThe DropTargetEvent.
