推荐答案
这个例子使用Java的内置CSS渲染能力来做重举的决定什么时候换线。它使用 JLabel ，但相同的原则适用于将呈现HTML的任何组件。
This example uses Java's inbuilt CSS rendering abilities to to do the 'heavy lifting' of determining when to do a line break. It uses a JLabel, but the same principles apply to any component that will render HTML.
import javax.swing.*;
class FixedWidthText {
public static void showLabel(int width, String units) {
String content1 = "<html>" +
"<body style='background-color: white; width: ";
String content2 = "'>" +
"<h1>Fixed Width</h1>" +
"<p>Body width fixed at ";
String content3 =
" using CSS. " +
"Java's HTML" +
" support includes support" +
" for basic CSS.</p>";
final String content =
content1 + width + units + content2 + width + units + content3;
Runnable r = new Runnable() {
public void run() {
JLabel label = new JLabel(content);
JOptionPane.showMessageDialog(null, label);
}
};
SwingUtilities.invokeLater(r);
}
public static void main(String[] args) {
showLabel(160, "px");
showLabel(200, "px");
showLabel(50, "%");
}
}
