JLabel的换行符
[英]Newline in JLabel
问题描述
How can I display a newline in JLabel ? 
如何在JLabel显示换行符？
For example, if I wanted: 例如，如果我想：
Hello World!
blahblahblah
This is what I have right now: 这就是我现在所拥有的：
JLabel l = new JLabel("Hello World!\nblahblahblah", SwingConstants.CENTER);
This is what is displayed: 这是显示的内容：
Hello World!blahblahblah
Forgive me if this is a dumb question, I'm just learning some Swing basics... 请原谅我，如果这是一个愚蠢的问题，我只是学习一些Swing基础...

用<html></html>包围字符串并用<br/>打破行。
JLabel l = new JLabel("<html>Hello World!<br/>blahblahblah</html>", SwingConstants.CENTER);

You can try and do this: 你可以尝试这样做：
myLabel.setText("<html>" + myString.replaceAll("<","<").replaceAll(">", ">").replaceAll("\n", "<br/>") + "</html>")
The advantages of doing this are: 这样做的好处是：
- It replaces all newlines with
<br/>, without fail.它取代所有换行符<br/>，没有失败。 - It automatically replaces eventual
<and>with<它会自动用<替换最终的<和>and>和>respectively, preventing some render havoc.分别防止一些渲染破坏。
What it does is: 它的作用是：
-
"<html>" +adds an openinghtmltag at the beginning"<html>" +在开头添加一个开头的html标签 -
.replaceAll("<", "<").replaceAll(">", ">")escapes<and>for convenience.replaceAll("<", "<").replaceAll(">", ">")为了方便而逃避<和> -
.replaceAll("\\n", "<br/>")replaces all newlines bybr(HTML line break) tags for what you wanted.replaceAll("\\n", "<br/>")用br（HTML换行符）标签替换所有换行符。 - ... and
+ "</html>"closes ourhtmltag at the end....和+ "</html>"关闭我们的html标签。

Thanks Aakash for recommending JIDE MultilineLabel. 感谢Aakash推荐JIDE MultilineLabel。 JIDE's StyledLabel is also enhanced recently to support multiple line. JIDE的StyledLabel最近也得到了增强，以支持多线。 I would recommend it over the MultilineLabel as it has many other great features. 我会推荐它通过MultilineLabel，因为它有许多其他很棒的功能。 You can check out an article on StyledLabel below. 您可以在下面查看有关StyledLabel的文章。 It is still free and open source. 它仍然是免费和开源的。

JLabel is actually capable of displaying some rudimentary HTML, which is why it is not responding to your use of the newline character (unlike, say, System.out). JLabel实际上能够显示一些基本的HTML，这就是为什么它没有响应你对换行符的使用（不像System.out）。
If you put in the corresponding HTML and used <BR> , you would get your newlines. 如果您输入相应的HTML并使用<BR> ，您将获得新行。
