java.awt.dnd.DragGestureEvent
| Constructor Summary | |
| public | DragGestureEvent(DragGestureRecognizer dgr, int act, Point ori, List<? extends InputEvent> evs)
Constructs a DragGestureEvent given the
DragGestureRecognizer firing this event,
an int representing
the user's preferred action, a Point
indicating the origin of the drag, and a List
of events that comprise the gesture. |
| Method Summary | |
| public Component | getComponent()
Returns the Component associated
with this DragGestureEvent. | | public int | getDragAction()
Returns an int representing the
action selected by the user. | | public Point | getDragOrigin()
Returns a Point in the coordinates
of the Component over which the drag originated. | | public DragSource | getDragSource()
Returns the DragSource. | | public DragGestureRecognizer | getSourceAsDragGestureRecognizer()
Returns the source as a DragGestureRecognizer. | | public InputEvent | getTriggerEvent()
Returns the initial event that triggered the gesture. | | public Iterator<InputEvent> | iterator()
Returns an Iterator for the events
comprising the gesture. | | public void | startDrag(Cursor dragCursor, Transferable transferable)
Starts the drag operation given the Cursor for this drag
operation and the Transferable representing the source data
for this drag operation.
If a null Cursor is specified no exception will
be thrown and default drag cursors will be used instead.
If a null Transferable is specified
NullPointerException will be thrown.
Parameters:
dragCursor - The initial Cursor for this drag operationor null for the default cursor handling;see DragSourceContextfor more details on the cursor handling mechanismduring drag and drop
Parameters:
transferable - The Transferable representing the sourcedata for this drag operation.
throws:
InvalidDnDOperationException - if the Drag and Dropsystem is unable to initiate a drag operation, or if the user attempts to start a drag while an existing drag operation isstill executing. | | public void | startDrag(Cursor dragCursor, Transferable transferable, DragSourceListener dsl)
Starts the drag given the initial Cursor to display,
the Transferable object,
and the DragSourceListener to use. | | public void | startDrag(Cursor dragCursor, Image dragImage, Point imageOffset, Transferable transferable, DragSourceListener dsl)
Start the drag given the initial Cursor to display,
a drag Image, the offset of
the Image,
the Transferable object, and
the DragSourceListener to use. | | public Object[] | toArray()
Returns an Object array of the
events comprising the drag gesture. | | public Object[] | toArray(Object[] array)
Returns an array of the events comprising the drag gesture. |
| DragGestureEvent | | public DragGestureEvent(DragGestureRecognizer dgr, int act, Point ori, List<? extends InputEvent> evs)(Code) | | Constructs a DragGestureEvent given the
DragGestureRecognizer firing this event,
an int representing
the user's preferred action, a Point
indicating the origin of the drag, and a List
of events that comprise the gesture.
Parameters:
dgr - The DragGestureRecognizer firing this event
Parameters:
act - The the user's preferred action
Parameters:
ori - The origin of the drag
Parameters:
evs - The List of events that comprise the gesture
throws:
IllegalArgumentException - if input parameters are null
