Package java.awt.dnd

Interface Summary

Autoscroll During DnD operations it is possible that a user may wish to drop the subject of the operation on a region of a scrollable GUI control that is not currently visible to the user.
DragGestureListener This interface is sourced from a DragGestureRecognizer and is invoked when an object of that (sub)class detects a drag initiating gesture.
DragSourceListener The DragSourceListener defines the event interface for originators of Drag and Drop operations to track the state of the user's gesture, and to provide appropriate "drag over" feedback to the user throughout the Drag and Drop operation.
DragSourceMotionListener A listener interface for receiving mouse motion events during a drag operation.
DropTargetListener The DropTargetListener interface is the callback interface used by the DropTarget class to provide notification of DnD operations that involve the subject DropTarget.

Class Summary

DnDConstants This class contains constant values representing the type of action(s) to be performed by a Drag and Drop operation.
DragGestureEvent A DragGestureEvent is passed to DragGestureListener's dragGestureRecognized() method when a particular DragGestureRecognizer detects that a platform dependent drag initiating gesture has occurred on the Component that it is tracking.
DragGestureRecognizer The DragGestureRecognizer is an abstract base class for the specification of a platform-dependent listener that can be associated with a particular Component in order to identify platform-dependent drag initiating gestures.
DragSource The DragSource is the entity responsible for the initiation of the Drag and Drop operation, and may be used in a number of scenarios:
  • 1 default instance per JVM for the lifetime of that JVM.
DragSourceAdapter An abstract adapter class for receiving drag source events.
DragSourceContext The DragSourceContext class is responsible for managing the initiator side of the Drag and Drop protocol.
DragSourceDragEvent The DragSourceDragEvent is delivered from the DragSourceContextPeer, via the DragSourceContext, to the DragSourceListener registered with that DragSourceContext and with its associated DragSource.
DragSourceDropEvent The DragSourceDropEvent is delivered from the DragSourceContextPeer, via the DragSourceContext, to the dragDropEnd method of DragSourceListeners registered with that DragSourceContext and with its associated DragSource.
DragSourceEvent This class is the base class for DragSourceDragEvent and DragSourceDropEvent.
DropTarget The DropTarget is associated with a Component when that Component wishes to accept drops during Drag and Drop operations.
DropTarget.DropTargetAutoScroller this protected nested class implements autoscrolling
DropTargetAdapter An abstract adapter class for receiving drop target events.
DropTargetContext A DropTargetContext is created whenever the logical cursor associated with a Drag and Drop operation coincides with the visible geometry of a Component associated with a DropTarget.
DropTargetContext.TransferableProxy TransferableProxy is a helper inner class that implements Transferable interface and serves as a proxy for another Transferable object which represents data transfer for a particular drag-n-drop operation.
DropTargetDragEvent The DropTargetDragEvent is delivered to a DropTargetListener via its dragEnter() and dragOver() methods.
DropTargetDropEvent The DropTargetDropEvent is delivered via the DropTargetListener drop() method.
DropTargetEvent The DropTargetEvent is the base class for both the DropTargetDragEvent and the DropTargetDropEvent.
MouseDragGestureRecognizer This abstract subclass of DragGestureRecognizer defines a DragGestureRecognizer for mouse-based gestures.
