java.awt.dnd.MouseDragGestureRecognizer
| MouseDragGestureRecognizer | | abstract public class MouseDragGestureRecognizer extends DragGestureRecognizer implements MouseListener,MouseMotionListener(Code) | | This abstract subclass of DragGestureRecognizer
defines a DragGestureRecognizer
for mouse-based gestures.
Each platform implements its own concrete subclass of this class,
available via the Toolkit.createDragGestureRecognizer() method,
to encapsulate
the recognition of the platform dependent mouse gesture(s) that initiate
a Drag and Drop operation.
Mouse drag gesture recognizers should honor the
drag gesture motion threshold, available through
DragSource.getDragThreshold .
A drag gesture should be recognized only when the distance
in either the horizontal or vertical direction between
the location of the latest mouse dragged event and the
location of the corresponding mouse button pressed event
is greater than the drag gesture motion threshold.
Drag gesture recognizers created with
DragSource.createDefaultDragGestureRecognizer follow this convention.
