JScrollPane 的滚动事件
奇怪的是 JScrollPane 没有方法 addAdjustmentListener().然而，adjustmentListener 据说是与滚动条一起使用的.每当 JScrollPane 以任何一种方式滚动时，我都希望发生一些事情.如何实现这样的事情?
It's strange that JScrollPane doesn't have a method addAdjustmentListener(). Yet adjustmentListener is said to be used with scrollbars. I want something to happen whenever the JScrollPane is scrolled in either way. How to achieve such a thing?
推荐答案
为什么不获取实际的滚动条，然后向它们添加调整侦听器?JScrollBar 有一个名为 addAdjustmentListener() 的方法.
Why don't you get the actual scrollbars, and then add adjustment listeners to them? JScrollBar has a method called addAdjustmentListener().
您可以使用 getVerticalScrollBar() 和 getHorizontalScrollBar() 从 JScrollPane 中获取 JScrollBar
And you can use getVerticalScrollBar() and getHorizontalScrollBar() to get a JScrollBar from a JScrollPane
