GridBagLayout Problem

[herzberg]

Das ist mir schon klar, dass das bei dir nicht funktioniert. Du erzeugst zwar alles nötige, fügst es aber nie ein. Ich habe dir das mal erweitert.

public class MyFrame extends JFrame{
	JPanel pnPanel0;
	JLabel lbLabel0;
	JLabel lbLabel1;
	JLabel lbLabel2;
	JList lsList0;
	JList lsList1;
	JList lsList2;
	JLabel lbLabel3;
	JLabel lbLabel4;
	JLabel lbLabel5;
	JTextField tfText0;
	JTextField tfText1;
	JTextField tfText2;
	JList lsList3;
	JButton btBut0;
	JButton btBut1;
	JButton btBut2;
	JButton btBut3;
