使用 Java Swing，您可以将 JLabel 大小设置为与默认 − 不同的首选大小
JLabel label.setPreferredSize(new Dimension(250, 100));
以下是更改 JLabel 大小的示例 −
示例
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Font;
import javax.swing.*;
import javax.swing.border.Border;
public class SwingDemo {
public static void main(String args[]) {
JFrame frame = new JFrame("Demo");
JLabel label;
label = new JLabel("This is demo label!",JLabel.RIGHT);
label.setVerticalAlignment(JLabel.TOP);
label.setFont(new Font("Verdana", Font.PLAIN, 15));
label.setPreferredSize(new Dimension(250, 100));
label.setForeground(new Color(120, 90, 40));
label.setBackground(new Color(100, 20, 70));
Border border = BorderFactory.createLineBorder(Color.ORANGE);
label.setBorder(border);
frame.add(label);
frame.setSize(600,300);
frame.setVisible(true);
}
}
