problem: open a frame in a thread

[kalar]

I want to have a thread and in this thread i want to make a JFrame window
i try this but i think it doesn't work correct:

public class AboutWindow  implements Runnable
{
        Thread hello ;
        public AboutWindow()
        {
        	hello = new Thread();
        	hello.start();

        }
    
    public static void main(String[] args)
    {
    	AboutWindow hd = new AboutWindow();
    	
    }

        public void run( )
        {
        JFrame tes = new JFrame();
        tes.setVisible(true);
    	tes.setSize(400,330); //300,200
    	tes.setLocation(450,200);
    	Container contentPane = tes.getContentPane();
    	tes.setLayout(new BorderLayout());
    	tes.setResizable(false);
    	tes.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    	contentPane.setBackground(Color.CYAN);
    	
    	JLabel th = new JLabel("heloo");
    	contentPane.add(th,BorderLayout.CENTER);   
        } 
}

It only opens a JFrame without the label tha i add on lines:29-30 and also i can't close it from x in the window.( it only dissapear the window, but back it still running).Where is the problem?

Your AboutWindow is a Runnable that should be passed the Thread constructor.
The Thread will run it when it is started itself (read the API documentation for
the Thread class). So your constructor should look like this:

[code=java]
public AboutWindow() {
hello = new Thread(this);
hello.start();
}
[/code]

kind regards,

Opening a window in a non-EDT is a bad idea. Please study this:
