JScrollPane单词换行 [英] JScrollPane words wrap
本文介绍了JScrollPane单词换行的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有问题。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（特殊于html标签）时，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的大小并设置必要的大小内部JPanel。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）。
如何解决这个问题？需要滚动垂直和水平单词换行。提前致谢。对不起，我的英文）。
I have a problem. In the JScrollPane I use inheritor of the JPanel as viewPort. The inheritor can contain labels, radio buttons, check boxes and other elements (depending on the implementation). In the JScrollPane set HORIZONTAL_SCROLLBAR_NEVER. It is necessary that contents in the inheritor of the JPanel scrolling in the vertical and horizontal words wrap. When displaying long texts in the labels (special in html tags) there is no word wrap, despite HORIZONTAL_SCROLLBAR_NEVER. If don't use JScrollPane (inheritor of the JPanel has concrete size) words to be wrapped, but I need a vertical scrolling.
Tried set listeners for resize JScrollPane and set necessary size for internal JPanel. Did not work. Set listeners for resize internal JPanel yet. After setting the width is happening another change back to (obviously of great importance).
How can I solve this problem? Requires scrolling in the vertical and horizontal words wrap. Thanks in advance. Sorry, for my English).
