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?
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
