Fields Summary
private static final long	serialVersionUID
private static final Point	zero
private Point	location The location of the drag cursor's hotspot in Component coordinates.
private int	actions The source drop actions.
private int	dropAction The user drop action.
private boolean	isLocalTx true if the source is in the same JVM as the target.

Constructors Summary
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, {@link #isLocalTransfer()} will return false. param dtc The DropTargetContext for this operation param cursorLocn The location of the "Drag" Cursor's hotspot in Component coordinates param dropAction the user drop action. param srcActions the source drop actions. throws NullPointerException if cursorLocn is null throws IllegalArgumentException if dropAction is not one of DnDConstants. throws IllegalArgumentException if srcActions is not a bitwise mask of DnDConstants. throws IllegalArgumentException if dtc is null. super(dtc); if (cursorLocn == null) throw new NullPointerException("cursorLocn"); if (dropAction != DnDConstants.ACTION_NONE && dropAction != DnDConstants.ACTION_COPY && dropAction != DnDConstants.ACTION_MOVE && dropAction != DnDConstants.ACTION_LINK ) throw new IllegalArgumentException("dropAction = " + dropAction); if ((srcActions & ~(DnDConstants.ACTION_COPY_OR_MOVE | DnDConstants.ACTION_LINK)) != 0) throw new IllegalArgumentException("srcActions"); location = cursorLocn; actions = srcActions; this.dropAction = dropAction;
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. param dtc The DropTargetContext for this operation param cursorLocn The location of the "Drag" Cursor's hotspot in Component's coordinates param dropAction the user drop action. param srcActions the source drop actions. param isLocal True if the source is in the same JVM as the target throws NullPointerException if cursorLocn is null throws IllegalArgumentException if dropAction is not one of DnDConstants. throws IllegalArgumentException if srcActions is not a bitwise mask of DnDConstants. throws IllegalArgumentException if dtc is null. this(dtc, cursorLocn, dropAction, srcActions); isLocalTx = isLocal;

Methods Summary
public void	acceptDrop(int dropAction) accept the drop, using the specified action. param dropAction the specified action getDropTargetContext().acceptDrop(dropAction);
public void	dropComplete(boolean success) This method notifies the DragSource that the drop transfer(s) are completed. param success a boolean indicating that the drop transfer(s) are completed. getDropTargetContext().dropComplete(success);
public java.awt.datatransfer.DataFlavor[]	getCurrentDataFlavors() This method returns the current DataFlavors. return current DataFlavors return getDropTargetContext().getCurrentDataFlavors();
public java.util.List	getCurrentDataFlavorsAsList() This method returns the currently available DataFlavors as a java.util.List. return the currently available DataFlavors as a java.util.List return getDropTargetContext().getCurrentDataFlavorsAsList();
public int	getDropAction() This method returns the user drop action. return the user drop actions. return dropAction;
public java.awt.Point	getLocation() This method returns a Point indicating the Cursor's current location in the Component's coordinates. return the current Cursor location in Component's coords. return location;
public int	getSourceActions() This method returns the source drop actions. return the source drop actions. return actions;
public java.awt.datatransfer.Transferable	getTransferable() This method returns the Transferable object associated with the drop. return the Transferable associated with the drop return getDropTargetContext().getTransferable();
public boolean	isDataFlavorSupported(java.awt.datatransfer.DataFlavor df) This method returns a boolean indicating if the specified DataFlavor is available from the source. param df the DataFlavor to test return if the DataFlavor specified is available from the source return getDropTargetContext().isDataFlavorSupported(df);
public boolean	isLocalTransfer() This method returns an int indicating if the source is in the same JVM as the target. return if the Source is in the same JVM return isLocalTx;
public void	rejectDrop() reject the Drop. getDropTargetContext().rejectDrop();
