Swing, Pluggable Look & Feel

With Swing, you can easily change the Look & Feel (L&F) at run time to match one of the L&F implementations in your system. This program contains strings identifying three different L&F implementations contained in Swing 1.0.3 for Win95. Compile and run the program to see PL&F in action. The key statements are:
 
plafClassName = motif;//or metal or windows  
UIManager.setLookAndFeel(plafClassName);
SwingUtilities.updateComponentTreeUI(thisPlafPanel);  
To change the L&F, assign a different L&F string to plafClassName and recompile the program. To upgrade the program to change the L&F at run time, assign a different L&F sting to plafClassName and execute the other two key statements. This code was tested using JDK1.1.6 and Swing 1.0.3 under Win95.
 
import java.awt.event.*;
import java.awt.*;
import com.sun.java.swing.*;
import java.util.*;

public class PlafStandalone01 extends JFrame {

	//Three L&F implementations contained in Swing 1.0.3
	// for Win95 follow.
	String metal = 
		"com.sun.java.swing.plaf.metal.MetalLookAndFeel";
	String motif = 
			"com.sun.java.swing.plaf.motif.MotifLookAndFeel";
	String windows = 
		"com.sun.java.swing.plaf.windows.WindowsLookAndFeel";

	String plafClassName;//store the L&F string here
	PlafStandalone01 thisPlafPanel = this;//ref to this obj
	//-----------------------------------------------------//
  
	public PlafStandalone01(){//constructor
		getContentPane().setLayout(new FlowLayout());
		getContentPane().add(new JButton("JButton"));
		getContentPane().add(new JToggleButton(
				"JToggleButton"));
		setTitle("Pluggable Look & Feel");
		setBounds(30,300,350,150);
    
		//Set the Look and Feel by enabling one of these
		//plafClassName = motif;
		//plafClassName = metal;
		plafClassName = windows;
		try{
			UIManager.setLookAndFeel(plafClassName);
		}catch(Exception ex){System.out.println(ex);}
      
		//Cause the L&F to become visible.
		SwingUtilities.updateComponentTreeUI(thisPlafPanel);
		this.setVisible(true);
	}//end constructor
	//=====================================================//

	public static void main(String[] args){
		new PlafStandalone01();
	}//end main()
}//end class PlafStandalone01
