Package
Description
java.awt
Contains all of the classes for creating user interfaces and for painting graphics and images.
java.awt.dnd
Drag and Drop is a direct manipulation gesture found in many Graphical User Interface systems that provides a mechanism to transfer information between two entities logically associated with presentation elements in the GUI.

  Class
  Description
  DragGestureListener
  The listener interface for receiving drag gesture events.
  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.
  DropTarget
  The `DropTarget` is associated with a `Component` when that `Component` wishes to accept drops during Drag and Drop operations.

  Class
  Description
  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.
  DragGestureListener
  The listener interface for receiving drag gesture events.
  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.
  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 `DragSourceListener`s registered with that `DragSourceContext` and with its associated `DragSource`.
  DragSourceEvent
  This class is the base class for `DragSourceDragEvent` and `DragSourceDropEvent`.
  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.
  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
  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`.
  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`.
  DropTargetListener
  The `DropTargetListener` interface is the callback interface used by the `DropTarget` class to provide notification of DnD operations that involve the subject `DropTarget`.
  InvalidDnDOperationException
  This exception is thrown by various methods in the java.awt.dnd package.
