It appears to work on Mac OS X with any installed L&amp;F.

The updateComponentTreeUI(...) method (referenced in the Changing the LAF After Startup link provided by trashgod) will only work on a FontUIResource, not a Font. This is only relevant if you need to change the Font multiple times after startup. 

<pre><code>import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
import javax.swing.plaf.*;

public class ChangeFont extends JFrame
{
 private int size = 12;
 private JComponent component;

 public ChangeFont()
 {
 JTextArea textArea = new JTextArea();
 textArea.append( "updateComponentTreeUI will only work on a FontUIResource\n\n" );
 textArea.append( "1) click the FontUIResource button as many times as you want\n" );
 textArea.append( "2) after you click the Font button, neither button will work" );
 getContentPane().add(textArea, BorderLayout.NORTH);

 JButton west = new JButton( "FontUIResource" );
 west.addActionListener( new ActionListener()
 {
 public void actionPerformed(ActionEvent e)
 {
 update( new FontUIResource("monospaced", Font.PLAIN, size) );
 }
 });
 getContentPane().add(west, BorderLayout.WEST );

 JButton east = new JButton( "Font" );
 east.addActionListener( new ActionListener()
 {
 public void actionPerformed(ActionEvent e)
 {
 update( new Font("monospaced", Font.PLAIN, size) );
 }
 });
 getContentPane().add(east, BorderLayout.EAST );

 component = new JTable(5, 5);
 getContentPane().add(component, BorderLayout.SOUTH);
 }

 private void update(Font font)
 {
 UIManager.put("Table.font", font);
 UIManager.put("TextArea.font", font);
 SwingUtilities.updateComponentTreeUI( this );
 size += 2;
 pack();
 }

 public static void main(String[] args)
 {

 frame.pack();

I have a java applet and the only look and feel that works properly is the native mac one. I wanted to make the fonts a bit larger and tried using the standard UIManager methods

UIManager.put("Label.font", new Font("Georgia", Font.PLAIN, 18));

This produces no change. It does not throw an exception, of course. 

Does anyone know if the native mac look and feel ignores these?

I know there are specific ways to make controls different sizes on mac but these only seem to make them smaller. You cannot make the controls larger than regular.

Does Java Mac OSX native look and feel respect UIManager font changes?

我有一个java applet，唯一能正常工作的外观是原生的mac。我想把字体做大一点，并尝试使用标准的UIManager方法UIManager.put("Label.font"，新字体(“Label.font”，Font.PLAIN，18))；这不会产生任何变化。当然，它不会抛出异常。有没有人知道原生mac的外观是否...
