如何使包裹在JScrollPane中的JTextPane缩小以适合文本 [英] How to make JTextPane wrapped in JScrollPane shrink to fit the text

问题描述

我有一个带有HTML文本的JTextPane.

I have a JTextPane with HTML text.

我使用了GroupLayout(使用WindowBuilder).

I used GroupLayout (using WindowBuilder).

我将JFrame的最小尺寸设置为800x600，因此用户不能使其小于此尺寸.

I've set the minimum size of my JFrame to 800x600 so the user cannot make it smaller than that.

该应用程序滚动很大JPanel整个窗口的大小.面板的顶部由包裹在JScrollPane中的JTextPane占据.我禁用了滚动条，并设置了JScrollPane的大小以使整个文本可见.

The app has a big scrolling JPanel the size of the entire window. The top part of the panel is taken up by a JTextPane wrapped in JScrollPane. I have disabled the scroll bars and sized the JScrollPane to make the entire text visible.

在组布局中，JScrollPane设置为在垂直方向上保持恒定，但在水平方向上保持不变.

In group layout the JScrollPane is set to stay constant vertically, but size horizontally.

我的问题是，当用户使窗口变大时，JScrollPane也会展开，但是现在在文本窗格的底部留有很大的空白.有没有一种方法可以使JTextPane缩小以适合其内容.

My issue is that when the user makes the window larger the JScrollPane also expands, but now there is a big white space left at the bottom of the text pane. Is there a way that I can make JTextPane shrink to fit its contents.

如果您建议使用其他布局，我也愿意尝试.

Also if you suggest a different layout, I would be willing to try it.
