i have a simple program, and i would like to add splash screen to it to make it look "cool". But i really don't know where/how to start..

public class myprogram extends JFrame{

  public myprogram(){//code}

  public void static main(String[] args){
    myprogram a = new myprogram();
    a.show();
  }
}

where should i add the splashscreen? i'm thinking of creating another JFrame and show it first, and then myprogram, but i failed, the splash screen only appears for 0.000000001 second i guess..

please help
tks

Hi,

You can put a progress bar with a fixed time for completion. We have done that for about 3-5 seconds and it also looks as if it is loading some files.

Adding a Progress bar is pretty straight forward.

class SplashWindow1 extends JWindow
{
    public SplashWindow1(String filename, Frame f)
    {
        super(f);
        JLabel l = new JLabel(new ImageIcon(filename));
        getContentPane().add(l, BorderLayout.CENTER);
        pack();
        Dimension screenSize =
          Toolkit.getDefaultToolkit().getScreenSize();
        Dimension labelSize = l.getPreferredSize();
        setLocation(screenSize.width/2 - (labelSize.width/2),
                    screenSize.height/2 - (labelSize.height/2));
        setVisible(true);
        screenSize = null;
        labelSize = null;
    }

Don't use a ProgressBar when there is nothing progressing, don't fool your customer.
Just set a time limit in the right code.

First create a JFrame, the mainframe of your program, that owns almost all visible things.
Then give that JFrame instance to the code you found.

maybe a bit better:

public void static main(String[] args){

  myprogram a = new myprogram();

  final SplashScreen splashScreen = new SplashScreen( "pic.jpg", a);
  SwingUtilities.invokeLater( new Runnable()
  {
    public void run()
    {
       splashScreen.setVisible( true );
    }
   } );

  a.setVisible(true);
}

Also class names should start with an uppercase letter, so it should be MyProgram and not myprogram.

// Insert your picture here :

  JLabel l1 = new JLabel(new ImageIcon("Images/Splash1.jpg"));

  Dimension sd = java.awt.Toolkit.getDefaultToolkit().getScreenSize();

  setLocation(sd.width / 2 - 310 / 2,
  sd.height / 2 - 265 / 2);

  setSize(310, 265);
  setVisible(true);
   }

  public static void main( String args[] )
   {
   Splash app = new Splash();
   }
