Add mouseListener to Labels in Array Loop

Question

I want to add mouseListener to all labels in the array. Every label should show an other card of the layout. If I use below code, all labels show card6. What is wrong?

sorry this is correct code..

    panList = new JPanel();
    panList.setBounds(0, 0, 206, 517);
    panList.setLayout(null);
    cs.add(panList);

    CreateCards();

    int y = 0;  

        for(i = 0 ; i < 6; i++) {
        String lblName = getString("lbl"+String.valueOf(i));
        lblSettingTitle[i] = new JLabel("  "+lblName);
        lblSettingTitle[i].setBounds(0, y+10, 206, 26);
        lblSettingTitle[i].addMouseListener(new MouseListener() {

            public void mouseClicked(MouseEvent e) {

                CardLayout cardLayout = (CardLayout) cards.getLayout();
                cardLayout.show(cards, "card"+String.valueOf(i));
            }
        });
        panList.add(lblSettingTitle[i]);
        y+=26;
        }
}

private void CreateCards() {
    card1 = new JPanel();
    card2 = new JPanel();
    cards = new JPanel(new CardLayout());
    cards.setBounds(206, 35, 814-206, 546-120);
    cs.add(cards);
    cards.add(card1, "card1");
    cards.add(card2, "card2");

}

Answer 1

the problem is when mouse-event fire value of i have value 6 or last value of for-loop

for (i = 0; i < 6; i++){}

you can create a jlable class and give a instance variable like lableindex so when mouse-event occurs you first get the lable index and then show corresponding card.

or

you can getname of the jlable and get index by removing lbl part of the jlable name and show corresponding card.for example if jlable name is lb12 then take 2 out and show card named card + 2 or card2

for example consider this example

public void mouseClicked(java.awt.event.MouseEvent e) {

        String index = ((JLabel)e.getSource()).getText().substring(xx,yy); // here xx , yy  depend on how you are naming jlables .this should return 2 if your lable is lbl2
        CardLayout cardLayout = (CardLayout) cards.getLayout();
        cardLayout.show(cards, "card" + index);
        System.out.println("card" + index);
}
