如何在没有HTML的情况下获得多线JLabel（或看起来完全相同的JTextArea） [英] How to get a multilined JLabel (or a JTextArea looking totally the same) without HTML
问题描述
我不能相信多线JLabel的最快解决方案是以下一个（文本来自var，所以我不想每个x字符手动放置HTML代码，它太丑了）：
I cant believe fastest solution for a multilined JLabel is the following one (text comes from a var, and so I dont want to put HTML code manually every x chars, its so ugly):
public class JMultilineLabel extends JTextArea{
private static final long serialVersionUID = 1L;
public JMultilineLabel(String text){
super(text);
setEditable(false);
setCursor(null);
setOpaque(false);
setFocusable(false);
setFont(UIManager.getFont("Label.font"));
setWrapStyleWord(true);
setLineWrap(true);
}
}
...确定它不是更好的处理方式这个????
... sure it isnt a better way to handle this????
推荐答案
如果你想要一个multilne标签，那么你只需使用 HTML 在其文本中，因为它们支持其使用。因此，使用线制动器标签< / br> 来打破行或在< p>< / p> 段落标记。
If you want a multilne label then you simply use HTML in its text, as they support its use. Therefore, use line brake tag </br> to break lines or put separate lines in <p></p> paragraph tags.
不要忘记标记您要将HTML用于 JLabel by使用< html> 标记开始发送文字。
Do not forget to mark that you want to use HTML for a JLabel by starting its text with the <html> tag.
顺便说一句我忘了检查是否有关于 JLabel 使用的其他相关问题并且至少有一些，请检查这个或这个。 :)
BTW I forgot to check if there were other related questions about JLabel use and there were at least a few, check this or this. :)
编辑：
对于工作样本，显示不同的方法，不设置样式并使用段落和标签占用可用空间，请参见下文：
For a working sample, showing a different approach, without setting a style and with use of paragraph and label taking available space, please see below:
import java.awt.BorderLayout;
import java.awt.Color;
import javax.swing.*;
public class LabelHTMLAutoResize {
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
JFrame f = new JFrame();
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel p = new JPanel(new BorderLayout());
JLabel l = new JLabel("<html><p> Some verrrry long text Some verrrry long Some verrrry long text dsa ads oiosi o</p>");
l.setVerticalAlignment(SwingConstants.TOP);
l.setOpaque(true);
l.setBackground(Color.green);
p.add(l);
f.setContentPane(p);
/* good practice is to use f.pack(); and let the size be automatically calculated but we want to show line wrapping thus frame size is set */
f.setSize(200, 200);
f.setVisible(true);
}
});
}
}
