javax.swing.plaf.basic.BasicScrollPaneUI.MouseWheelHandler

所有已实现的接口:

MouseWheelListener, EventListener

封闭类:

BasicScrollPaneUI

       protected class BasicScrollPaneUI.MouseWheelHandler extends Object implements MouseWheelListener
      

MouseWheelHandler是一个内部类，实现了MouseWheelListener接口。MouseWheelHandler通过适当地滚动JScrollPane来响应MouseWheelEvents。如果滚动窗格的isWheelScrollingEnabled方法返回false，则不会发生滚动。
