Hi all,
is there a way to change all fontsizes within a Java Swing Application.

Something like

UIManager.setGlobalFontsize(+3) ; // +3 means that all default fonts are increased in size by 3 ?

needs testing

import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
import java.util.Enumeration;
class Testing extends JFrame
  public Testing()
    JComboBox cbo = new JComboBox(new String[]{"abc","123"});
    JButton btn = new JButton("OK");
    JPanel p = new JPanel();
    getContentPane().add(new JLabel("I'm a label"),BorderLayout.NORTH);
  public void setApplicationFont(float increment)
    Enumeration enumer = UIManager.getDefaults().keys();
      Object key = enumer.nextElement();
      Object value = UIManager.get(key);
      if (value instanceof Font)
        UIManager.put(key, new
  public static void main(String[] args){new Testing().setVisible(true);}
