how to fake mouse event

Posted by Shay Gaghe on October 22, 2001 at 6:22 PM

Im using Java 1.3 for developing a Swing interface that contains a label and a button. The label associate with ToolTip. I need to perform a simple task , I want the ToolTip to be displayed when I press on the button (instead of mouse over on the label).

I know that I have to fake a mouse event on the label to get this trick to work. I did it with the following code but its not work:
[code]
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class NewToolTipTest extends JFrame
{
private JLabel l;
private JButton showTip;

public NewToolTipTest()
{
Image i = Toolkit.getDefaultToolkit().getImage( "images/miri.gif" );
ImageIcon ii = new ImageIcon( i );
l = new JLabel( ii );
l.setToolTipText( "Look, it's a ToolTip!" );
getContentPane().add( l, BorderLayout.CENTER );

showTip = new JButton( "Show Tip" );
// Don't give the button a tooltip! It will replace the
// tooltip you want to show!
//showTip.setToolTipText( "Push Me!" );
showTip.addActionListener( new TipActivate() );
getContentPane().add( showTip, BorderLayout.SOUTH );

addWindowListener( new ExitHandler() );
}

public static void main( String[] args )
{
NewToolTipTest nttt = new NewToolTipTest();
nttt.pack();
nttt.setVisible( true );
}

private class ExitHandler extends WindowAdapter
{
public void windowClosing( WindowEvent event )
{
System.exit( 0 );
}
}

private class TipActivate implements ActionListener
{
public void actionPerformed( ActionEvent event )
{
ToolTipManager theManager = ToolTipManager.sharedInstance();
MouseEvent toolTipEvent = new MouseEvent( l, MouseEvent.MOUSE_MOVED,
System.currentTimeMillis(), 0, 0, 0, 0, false );
theManager.mouseMoved( toolTipEvent );

System.out.println( "ActionEvent launched!");
}
}
}
[/code]
whats wrong?

Any replies will be best appreciated
