Constructors Summary

public DropTargetDragEvent(DropTargetContext dtc, Point cursorLocn, int dropAction, int srcActions) Construct a DropTargetDragEvent given the DropTargetContext for this operation, the location of the "Drag" Cursor's hotspot in the Component's coordinates, the user drop action, and the source drop actions. 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;

Methods Summary
public void	acceptDrag(int dragOperation) Accepts the drag. This method should be called from a DropTargetListeners dragEnter, dragOver, and dropActionChanged methods if the implementation wishes to accept an operation from the srcActions other than the one selected by the user as represented by the dropAction. param dragOperation the operation accepted by the target getDropTargetContext().acceptDrag(dragOperation);
public java.awt.datatransfer.DataFlavor[]	getCurrentDataFlavors() This method returns the current DataFlavors from the DropTargetContext. return current DataFlavors from the DropTargetContext return getDropTargetContext().getCurrentDataFlavors();
public java.util.List	getCurrentDataFlavorsAsList() This method returns the current DataFlavors as a java.util.List return a java.util.List of the Current DataFlavors return getDropTargetContext().getCurrentDataFlavorsAsList();
public int	getDropAction() This method returns the user drop action. return the user drop action return dropAction;
public java.awt.Point	getLocation() This method returns a Point indicating the Cursor's current location within 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 that represents the data associated with the current drag operation. return the Transferable associated with the drag operation throws InvalidDnDOperationException if the data associated with the drag operation is not available since 1.5 return getDropTargetContext().getTransferable();
public boolean	isDataFlavorSupported(java.awt.datatransfer.DataFlavor df) This method returns a boolean indicating if the specified DataFlavor is supported. param df the DataFlavor to test return if a particular DataFlavor is supported return getDropTargetContext().isDataFlavorSupported(df);
public void	rejectDrag() Rejects the drag as a result of examining either the dropAction or the available DataFlavor types. getDropTargetContext().rejectDrag();
