im trying to to use cards layout, and i have 2 buttons at the the top that supoose to change the card but for some reason it wont work, the next method works but the show or first\last doesnt, ofcourse i cant use next, cause i want a specific card for every button, here is my code:
cards = new CardLayout();
cardPanel = new JPanel();
cardPanel.setLayout(cards);
cards.show(cardPanel, "gapas");
JPanel firstCard = new JPanel();
firstCard.setBackground(Color.WHITE);;
JPanel secondCard = new JPanel();
secondCard.setBackground(Color.blue);
cardPanel.add(firstCard, "kalam");
cardPanel.add(secondCard, "gapan");
guiFrame.add(tabsPanel,BorderLayout.NORTH);
guiFrame.add(cardPanel,BorderLayout.CENTER);
guiFrame.setVisible(true);
}
ActionListener action = new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
if(e.getActionCommand().matches("kalam")){
cards.show(cardPanel,"kalam");
System.out.println("kalam");
}
else{
cards.show(cardPanel, "gapas");
System.out.println("gapas");
}
}
};
I think you want something like this.
public class TestCard extends JFrame implements ActionListener {
CardLayout cards;
JPanel cardPanel, tabsPanel;
JButton b1, b2;
public TestCard() {
b1= new JButton("kalam");
b2= new JButton("gapas");
tabsPanel = new JPanel();
cards = new CardLayout();
cardPanel = new JPanel();
cardPanel.setLayout(cards);
JPanel firstCard = new JPanel();
firstCard.setBackground(Color.WHITE);
JPanel secondCard = new JPanel();
secondCard.setBackground(Color.blue);
cardPanel.add(firstCard, "kalam");
cardPanel.add(secondCard, "gapas");
tabsPanel.add(b1);
tabsPanel.add(b2);
add(tabsPanel, BorderLayout.NORTH);
add(cardPanel, BorderLayout.CENTER);
b1.addActionListener(this);
b2.addActionListener(this);
setSize(800, 600);
cards.show(cardPanel, "gapas");
setVisible(true);
}
@Override
public void actionPerformed(ActionEvent e) {
if (e.getActionCommand().matches("kalam")) {
cards.show(cardPanel, "kalam");
System.out.println("kalam");
} else {
cards.show(cardPanel, "gapas");
System.out.println("gapas");
}
}
public static void main(String[] args) {
new TestCard();
}
}
