Thread: My frame wont show anything

My components dont show until I resize the frame.

public class Frame extends JFrame{
 
	private final static int WIDTH=400, HEIGHT=400;
 
    public Frame(){
        super();
        super.setSize(WIDTH,HEIGHT);
		super.setVisible(true);
        super.setDefaultCloseOperation(EXIT_ON_CLOSE);
    }
 
}

	public class Panel extends JPanel{
 
		private JTextField name;
 
 
 
	    public Panel(){
	    	super.setLayout(new BorderLayout());
	        DrinkName = new JTextField(20);
	        this.add(DrinkName, BorderLayout.SOUTH);
 
 
	    }
 
	}

In my main class I am just creating the frame and the panel then adding the panel to the frame.

Please refer to a basic Swing tutorial, like this one. There's also this index to choose from when you're ready to move to the next topic.

I figured out that the problem was in my main. I rearranged the way I created the panel and frame and then put the panel in the frame. It is working now.

One more question... Which class is recommended for button listeners? Are they allowed to go in the main?
