I have this snippet of code that when I step through never goes into:
when I put a break point in the " class SD extends javax.swing.JWindow"
and when i get to the code "m_SplashWindow = new SD( this, imgSplash );"
it doesnt go to the break point at all in the class so its like it bypassing
this class.
Does anyone have any ideas why?
Thanks

public class frmMain extends javax.swing.JFrame


  private void formWindowOpened (java.awt.event.WindowEvent evt) {
    // Add your handling code here:
    SplashScreenFrame m_SplashScreen = new SplashScreenFrame();
    }
}

class SplashScreenFrame extends javax.swing.JFrame
{
  SD m_SplashWindow;
  Image imgSplash;

  SplashScreenFrame()
  {
    super();
    Toolkit toolkit = Toolkit.getDefaultToolkit();
    imgSplash = toolkit.getImage( "splash.gif" );
    m_SplashWindow = new SD( this, imgSplash );
  }

//  public static void main( String[] args )
//  {
//    new SplashScreenFrame().show();
//    SplashScreenFrame m_SplashScreenFrame = new SplashScreenFrame();
//  }
}

class SD extends javax.swing.JWindow
{
  Image imgSplashImg;

  SD( Frame parent, Image imgSplash )
  {
    super( parent );
    imgSplashImg = imgSplash;
    setSize( 518, 312 );

    Dimension m_ScreenDim = Toolkit.getDefaultToolkit().getScreenSize();
    Rectangle m_Rect = getBounds();
    setLocation( ( m_ScreenDim.width - m_Rect.width ) / 2,
                 ( m_ScreenDim.height - m_Rect.height ) / 2 );
    setVisible( true );
  }

  public void paint( Graphics g )
  {
    if( imgSplashImg != null )
      g.drawImage( imgSplashImg, 0, 0, this );
  }
