Packages that use java.awt.dnd
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.

Classes in java.awt.dnd used by java.awt

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.

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.
