How to create fancy buttons in your application |
|
|
This Java Swing tip illustrates a method of creating fancy buttons in your
applications. The code uses JButton as the base and then add a roll over
image on the button. This code may be generally used by game developers
for creating animation in their widgets.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class ButtonTest extends JFrame {
private JButton plainButton, fancyButton;
public ButtonTest()
{
super( "Testing Buttons" );
Container c = getContentPane();
c.setLayout( new FlowLayout() );
// create buttons
plainButton = new JButton( "Plain Button" );
c.add( plainButton );
Icon bug1 = new ImageIcon( "bug1.gif" );
Icon bug2 = new ImageIcon( "bug2.gif" );
fancyButton = new JButton( "Fancy Button", bug1 );
fancyButton.setRolloverIcon( bug2 );
c.add( fancyButton );
// create an instance of inner class ButtonHandler
// to use for button event handling
ButtonHandler handler = new ButtonHandler();
fancyButton.addActionListener( handler );
plainButton.addActionListener( handler );
setSize( 275, 100 );
show();
}
public static void main( String args[] )
{
ButtonTest app = new ButtonTest();
app.addWindowListener(
new WindowAdapter() {
public void windowClosing( WindowEvent e )
{
System.exit( 0 );
}
}
);
}
// inner class for button event handling
private class ButtonHandler implements ActionListener {
public void actionPerformed( ActionEvent e )
{
JOptionPane.showMessageDialog( null,
"You pressed: " + e.getActionCommand() );
}
}
}
