如何在 JTextArea 中换行

Question

I have a JTextArea in Java. When I place a large amount of text in it, the text area provides horizontal scrolling.

How can I make my text area wrap instead?

Answer 1

Use the JTextArea#setLineWrap method. This is also illustrated in the Swing JTextArea tutorial

Answer 2

查看 JTextArea 可用方法的 API，特别是setWrapStyleWord和setLineWrap 。

Answer 3

尝试这个 ：

jTextArea.setLineWrap(true);

Answer 4

In a Swing GUI Designer Like Netbeans IDE,

you could just 'check' the lineWrap in jTextArea property window.

if property window is hidden:

Goto WINDOW -> IDE TOOLS -> Properties

or press

CTRL + SHIFT + 7

In Swing GUI

add the line

jTextArea.setLineWrap(true);

Answer 5

您将需要使用它来包装带有多个单词的文本。

JTextArea.setWrapStyleWord(true);
