DropTarget is the target of a Drag&Drop operation; it defines where a UI element moved by Drag&Drop is ultimately positioned. The DropTarget itself is not visualized, it is just an invisible frame or an invisible container around another UI element and prepares an area for the insertion of contents.
A DropTarget requires information about the corresponding DropTargetInfo and the UI element or the UI elements which are visualized.The aggregations below are provided for this purpose.
