Constructor Summary

DropDragShapeComponent(Shape shape, boolean filled, Color color)

Method Summary

boolean	acceptDrop(Object dropped) You should override this method in subclass to get drag/drop to work with your shapes.
void	addDragListener() Allows this Shape to listen for Drag & Drop
void	addKeyboardListener() Allows this Shape to Listen for Arrow Keys Note: Only one shape will listen for key strokes at a time to obtain the focus for this shape, you need to call the Shape's getFocus() method.
void	addMouseListener() Allows this Shape to listen for Mouse Events.
void	dragDropEnd(DragSourceDropEvent dsde) You should not need to use this method
void	dragEnter(DragSourceDragEvent dsde) You should not need to use this method
void	dragExit(DragSourceEvent dse) You should not need to use this method
void	dragOver(DragSourceDragEvent dsde) You should not need to use this method
void	dropActionChanged(DragSourceDragEvent dsde) You should not need to use this method
Object	getTransferData(DataFlavor flavor) You should not need to use this method
DataFlavor[]	getTransferDataFlavors() You should not need to use this method
boolean	isDataFlavorSupported(DataFlavor flavor) You should not need to use this method
Object	manufactureDroppable() You should override this method in subclass to get drag/drop to work with your shapes.
boolean	okToDrag() Returns whether it's OK to drag this object
void	removeDragListener() Removes this Shape's ability to listen for Drag & Drop
void	removeKeyboardListener() Removes this Shape's ability to Listen for Arrow Keys
void	removeMouseListener() Removes Shape's ability to listen for Mouse Events.
void	resetBorder() You should not need to use this method
void	setInvolvedInDrop(canvas.DragComponent drop)
void	setListener(canvas.DefaultListener newListener) Will set the listener from the default to your subclass of a DefaultListener so you can obtain function from the listeners
