public abstract class MouseDragGestureRecognizer extends DragGestureRecognizer implements MouseListener, MouseMotionListener
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(java.awt.Component, int, java.awt.dnd.DragGestureListener) follow this convention.
