使用UIManager
定义JLabel的默认字体:
import java.awt.FlowLayout;
import java.awt.Font;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.UIManager;
public class LabelFont {
public static void main(String[] args) {
Font oldLabelFont = UIManager.getFont("Label.font");
UIManager.put("Label.font", oldLabelFont.deriveFont(Font.PLAIN));
JFrame f = new JFrame("LabelFont Test");
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.getContentPane().setLayout(new FlowLayout());
JLabel df = new JLabel("Default JLabel font");
f.getContentPane().add(df);
JLabel ef = new JLabel("Font explicitly set");
ef.setFont(oldLabelFont);
f.getContentPane().add(ef);
f.pack();
f.setVisible(true);
}
}

这是你在找什么?
import java.awt.FlowLayout;
import java.awt.Font;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.UIManager;
public class LabelFont {
public static void main(String[] args) {
Font oldLabelFont = UIManager.getFont("Label.font");
UIManager.put("Label.font", oldLabelFont.deriveFont(Font.PLAIN));
JFrame f = new JFrame("LabelFont Test");
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.getContentPane().setLayout(new FlowLayout());
JLabel df = new JLabel("Default JLabel font");
f.getContentPane().add(df);
JLabel ef = new JLabel("Font explicitly set");
ef.setFont(oldLabelFont);
f.getContentPane().add(ef);
f.pack();
f.setVisible(true);
}
}
