source]
java.lang.Object
java.awt.event.MouseAdapter
javax.swing.plaf.basic.BasicSplitPaneDivider$MouseHandler
All Implemented Interfaces:
MouseMotionListener, MouseListener, MouseWheelListener
MouseHandler is responsible for converting mouse events
(released, dragged...) into the appropriate DragController
methods.

If dragger is not null it is messaged with continueDrag. |
public void mouseEntered(MouseEvent e) {

}
} Invoked when the mouse enters a component. |
public void mouseExited(MouseEvent e) {
if (e.getSource() == BasicSplitPaneDivider.this) {
setMouseOver(false);
}
} Invoked when the mouse exits a component. |
public void mouseMoved(MouseEvent e) {
} Resets the cursor based on the orientation. |

} Starts the dragging session by creating the appropriate instance
of DragController. |
