Constructor Detail

DropTargetDropEvent

public DropTargetDropEvent(DropTargetContext dtc,
                           Point cursorLocn,
                           int dropAction,
                           int srcActions)
Construct a DropTargetDropEvent given the DropTargetContext for this operation, the location of the drag Cursor's hotspot in the Component's coordinates, the currently selected user drop action, and the current set of actions supported by the source. By default, this constructor assumes that the target is not in the same virtual machine as the source; that is, isLocalTransfer() will return false.

Parameters:
dtc - The DropTargetContext for this operation
cursorLocn - The location of the "Drag" Cursor's hotspot in Component coordinates
dropAction - The currently selected user drop action: COPY, MOVE, or LINK constants found in DnDConstants.
srcActions - The current set of actions supported by the source: some combination of COPY, MOVE, or LINK as exposed by the DragSource.

Throws:
NullPointerException - if cursorLocn is null
IllegalArgumentException - if the dropAction or srcActions are illegal values, or if dtc is null.

DropTargetDropEvent

public DropTargetDropEvent(DropTargetContext dtc,
                           Point cursorLocn,
                           int dropAction,
                           int srcActions,
                           boolean isLocal)
Construct a DropTargetEvent given the DropTargetContext for this operation, the location of the drag Cursor's hotspot in the Component's coordinates, the currently selected user drop action, the current set of actions supported by the source, and a boolean indicating if the source is in the same JVM as the target.

Parameters:
dtc - The DropTargetContext for this operation
cursorLocn - The location of the "Drag" Cursor's hotspot in Component's coordinates
dropAction - The currently selected user drop action: COPY, MOVE, or LINK constants found in DnDConstants.
srcActions - The current set of actions supported by the source: some combination of COPY, MOVE, or LINK as exposed by the DragSource.
isLocalTx - True if the source is in the same JVM as the target
Method Detail
