Swapping static gifs with animated gifs

Question

Hi
I am currently developing a large application. I created a toolbar with many button functions. The buttons are created as image icons. I created the gifs using Fireworks for the toolbar. A couple are animated as I would like to have the static image swapped with the animated image when the button is passed over with the mouse. Currently the animation will loop no matter where the mouse is which can be quite annoying to the user. Separate sample code follows:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class AnimationTest extends JFrame
     JToolBar toolbar;
     JButton btnSave, btnRestore;
     public AnimationTest()
          toolbar = new JToolBar();
          btnSave = new JButton(new ImageIcon("btnSaveAnim.gif"));
          toolbar.add( btnSave );
          btnRestore = new JButton( new ImageIcon( "btnRestoreAnim.gif" ));
          toolbar.add( btnRestore );
          getContentPane().add( toolbar, BorderLayout.NORTH );
          addWindowListener( new WinClosing() );
          setBounds( 100, 100, 100, 100 );
          setVisible( true );
     public static void main( String args[] )
          AnimationTest at = new AnimationTest();
class WinClosing extends WindowAdapter
     public void windowClosing( WindowEvent we )
          System.exit(0);
}How can I create a rollover event when the static gif is passed over with the mouse?
Any suggestion would be greatly appreciated. Thanks.

Answer 1

I had the same problem and the setRolloverEnabled(true) and setRollOverIcon(Icon) methods did nothing. The problem is solved by simply adding mouse listeners to each button and using mouseEntered(MouseEvent e) and mouseExited(MouseEvent E) methods within th elistener.
It was the only way I could get it working.
Good luck.
