GUI won't refresh

Question

I'm working on a textbased simple roleplaying game for my exame, but i have ran into some problems with my gui.

When the player registers, he can spend some attribute points in 3 categories. The gui is programmed to show the Raise Strength etc. button, if the player have any attribute points.

And that works cool, but then when the player clicks on a raise button, an attributepoint is taken for him, the problem is, that the gui doesn't seem to update.

if(Controller.player.getAttributePoints() > 0) {
        JLabel attriL = new JLabel("You have " + Controller.player.getAttributePoints() + " unspent Attribute points."); 
        attriL.setBounds(110, 30, 250, 30);
        hPanel.add(attriL);

        JButton setStrB = new JButton("Raise Strength");
        setStrB.setBounds(125, 60, 200, 30);
        setStrB.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
             //   tabbedPane.removeAll();                    
                Controller.player.setAttributePoints(Controller.player.getAttributePoints()-1);
                Controller.player.setStrength(Controller.player.getStrength()+1);

                gameCtn.validate();
                gameCtn.repaint();
                System.out.println(Controller.player.getStrength());                    
            }
        });
        hPanel.add(setStrB);
}

As you can see i have tried using repaint and validate on my container but with no luck, also i have tried on the Frame, and the panel, nothing seems to work? Am i doing something wrong?

Thx

not clear if Controller... didn't invoked long timed and hard taks, basically (if you remove and then add new JComponents) to the GUI then you have to call

revalidate();
repaint();// not required on all cases

simple demonstrations what's happens, what's possible or most completed here

Sorry about that.

You have no code that says to make the button invisible.

public void actionPerformed(ActionEvent evt) {
    ...
    if (whateverIsLeft < 1) {
        JButton src = (JButton)evt.getSource();
        src.setVisible(false);
    }

    attriL.setText("You have " + whateverIsLeft + " attribute points left");
}

Hey Black Panda, no the problem is that the buttons should dissapear when Controller.player.getAttributePoints() is less than 1, but nothing happens. – MartinElvar Dec 11 '11 at 11:27
