abstract public class: MouseDragGestureRecognizer [javadoc | source]
java.lang.Object
   java.awt.dnd.DragGestureRecognizer
      java.awt.dnd.MouseDragGestureRecognizer

All Implemented Interfaces:
    MouseListener, MouseMotionListener, java$io$Serializable

Direct Known Subclasses:
    DefaultMouseDragGestureRecognizer

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.

Fields inherited from java.awt.dnd.DragGestureRecognizer:
dragSource,  component,  dragGestureListener,  sourceActions,  events
Constructor:
 protected MouseDragGestureRecognizer(DragSource ds) 
    Construct a new MouseDragGestureRecognizer given the DragSource for the Component.

    Parameters:
    ds - The DragSource for the Component
 protected MouseDragGestureRecognizer(DragSource ds,
    Component c) 
    Construct a new MouseDragGestureRecognizer given the DragSource for the Component c, and the Component to observe.

    Parameters:
    ds - The DragSource for the Component c
    c - The Component to observe
 protected MouseDragGestureRecognizer(DragSource ds,
    Component c,
    int act) 
    Construct a new MouseDragGestureRecognizer given the DragSource for the Component c, the Component to observe, and the action(s) permitted for this drag operation.

    Parameters:
    ds - The DragSource for the Component c
    c - The Component to observe
    act - The actions permitted for this drag
 protected MouseDragGestureRecognizer(DragSource ds,
    Component c,
    int act,
    DragGestureListener dgl) 
    Construct a new MouseDragGestureRecognizer given the DragSource for the Component c, the Component to observe, the action(s) permitted for this drag operation, and the DragGestureListener to notify when a drag gesture is detected.

    Parameters:
    ds - The DragSource for the Component c
    c - The Component to observe
    act - The actions permitted for this Drag
    dgl - The DragGestureListener to notify when a gesture is detected
