JScrollPane单词换行

Question

JScrollPane单词换行

我有个问题.在JScrollPane中,我使用JPanel的继承者作为viewPort.继承者可以包含标签,单选按钮,复选框和其他元素(取决于实现).在JScrollPane中设置HORIZONTAL_SCROLLBAR_NEVER.JPanel的继承者中的内容必须在垂直和水平单词中滚动.当在标签中显示长文本时(特殊于html标签),尽管有HORIZONTAL_SCROLLBAR_NEVER,但没有自动换行.如果不使用JScrollPane(JPanel的继承者具有具体大小)的话要包装,但我需要垂直滚动.

尝试设置侦听器以调整JScrollPane的大小,并为内部JPanel设置必要的大小.不工作.设置侦听器以调整内部JPanel的大小.在设定宽度后发生另一个变化(显然非常重要).

我怎么解决这个问题？需要在垂直和水平单词中滚动.提前致谢.对不起我的英语不好).
