Is there any MultiLine JLabel exist?
提问by Jame
I want to display some text in JLabel at runtime. I just want to know that is there anyway through which the text is dispalyed on multiple line e.g i want my text to be displayed in following format:
我想在运行时在 JLabel 中显示一些文本。我只是想知道无论如何都可以通过它在多行上显示文本，例如我希望我的文本以以下格式显示：
Line 1
Line 2
Line 3
String sText = "Line1 \n Line2 \n Line3";
jLabel1.setText (sText);
I tried the above code but its not working. Am i doning some thing wrong or JLabel doesn't support above said feature?
我尝试了上面的代码，但它不起作用。是我做错了什么还是 JLabel 不支持上述功能？
In case if i am unable to achieve the above functionality then please guide me how do i add multiple labels (one for each line) in JPanel at runtime
如果我无法实现上述功能，请指导我如何在运行时在 JPanel 中添加多个标签（每行一个）

JLabelsupports HTML. You can write:
JLabel支持 HTML。你可以写：
String sText = "<html>Line1 <br/> Line2 <br/> Line3</html>";
jLabel1.setText (sText);
Edit: I added back slashes with br tag in order to make code working
编辑：我用 br 标签添加了反斜杠以使代码工作

use <br>instead of using \n
and prefix it by <html>like this
使用<br>而不是使用 \n 并<html>像这样添加前缀
"<html>Line1 <br> Line2 <br> Line3</html>";

A better option for HTML formatted text in this case, is to drop the hard line breaks (except at the end of paragraphs) and set the width of the HTML using CSS.
在这种情况下，HTML 格式文本的更好选择是删除硬换行符（段落末尾除外）并使用 CSS 设置 HTML 的宽度。
As seen in the 2nd example (LabelRenderTest.java) shown here.
如所看到的在第二实施例（LabelRenderTest.java）中示出在这里。
