Java Foundation Classes in a Nutshell

You can create a DragSource object by calling the constructor, but because the DragSource

object does not hold any state, you can continually reuse a single object. Call the static

getDefaultDragSource() method to obtain a refer ence to a shared default DragSource object.

Once you have obtained a DragSource object, call createDefaultDragGestureRecognizer() to

cr eate and register a DragGestureRecognizer object that detects user gestures that should

initiate drags. If you want to drag an image that repr esents the dragged data along with

the drag cursor, you may also call the isDragImageSuppor ted() method to find out whether

that option is supported on the native platform.

After you have called these two methods, you typically never need to use the Drag-

Source again. The star tDrag() method of the DragSource is responsible for initiating a drag

action, but it is easier to invoke it through the star tDrag() utility method of the DragGes-

tureEvent class instead.
