Hello!

I've created an abstract class that extends from JPanel. If I create any class that extends this first class, that class doesn't show the componentes from the first class.

What can I do for showing the components?

public abstract class AbstractClass extends JPanel {

private JLabel jLabel = null;

public AbstractClass() {
super();
initialize();
}

private void initialize() {
GridBagConstraints gridBagConstraints = new GridBagConstraints();
gridBagConstraints.gridx = 0;
gridBagConstraints.gridy = 0;
jLabel = new JLabel();
jLabel.setText("JLabel");
this.setSize(300, 200);
this.setLayout(new GridBagLayout());
this.add(jLabel, gridBagConstraints);
}

}

public class A extends AbstractClass {

}
