public interface MouseMotionListener
extends EventListener

The listener interface for receiving mouse motion events on a component. (For clicks and other mouse events, use the MouseListener.)

The class that is interested in processing a mouse motion event either implements this interface (and all the methods it contains) or extends the abstract MouseMotionAdapter class (overriding only the methods of interest).

The listener object created from that class is then registered with a component using the component's addMouseMotionListener method. A mouse motion event is generated when the mouse is moved or dragged. (Many such events will be generated). When a mouse motion event occurs, the relevant method in the listener object is invoked, and the MouseEvent is passed to it.

Method Summary

void
mouseDragged(MouseEvent e)
Invoked when a mouse button is pressed on a component and then dragged.
void
mouseMoved(MouseEvent e)
Invoked when the mouse cursor has been moved onto a component but no buttons have been pushed.

Method Details

mouseDragged

public void mouseDragged(MouseEvent e)
Invoked when a mouse button is pressed on a component and then dragged. MOUSE_DRAGGED events will continue to be delivered to the component where the drag originated until the mouse button is released (regardless of whether the mouse position is within the bounds of the component).

Due to platform-dependent Drag&Drop implementations, MOUSE_DRAGGED events may not be delivered during a native Drag&Drop operation.
