I wan to add it in the "yes or no" command there. It's a pop up window that prompt users whether they are sure with their answers anot.

the window will show "ARe you confirm with this decision?" and there's a yes/no button to click on. but i dunno how to add in the cancel button in there.

Mick Barry

Use YES_NO_CANCEL_OPTION in showOptionDialog().

i tried adding the cancel button at the submit button there. but there's an error.

private JPanel createSimpleDialogBox()

{

final int numButtons = 3;
JRadioButton[] radioButtons = new JRadioButton[numButtons];

final ButtonGroup group = new ButtonGroup();

final String yesNoCommand = "yesno";

radioButtons [0]= new JRadioButton("<html>Good</html>");
 radioButtons[0].setActionCommand(yesNoCommand);

 radioButtons [1]= new JRadioButton("<html>Average</html>");
 radioButtons[1].setActionCommand(yesNoCommand);

 radioButtons [2]= new JRadioButton("<html>Bad</html>");
 radioButtons[2].setActionCommand(yesNoCommand);


 for (int i = 0; i < numButtons; i++) {
group.add(radioButtons[i]);
}

//select 1st button as default
radioButtons[0].setSelected(true);

JButton voteButton = new JButton("Submit");
JButton cancelButton = new JButton("Cancel");

cancelButton.addActionListener(new ActionListener()
{
 public void actionPerformed(ActionEvent e) {
 System.exit(0);
 return;
 }

});

voteButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
String command = group.getSelection().getActionCommand();

//yesnocommand
if (command == yesNoCommand) {
int n = JOptionPane.showConfirmDialog(
frame, "Are you confirm with this decision?",
"A Follow-up Question",
JOptionPane.YES_NO_OPTION);

if (n == JOptionPane.YES_OPTION) {
setLabel("Thanks for your Feedback.We will try our best to improve our services");
} else if (n == JOptionPane.NO_OPTION) {
setLabel("OK please try again");
}

 }
return;
}
});

 System.out.println("calling createPane");
return createPane(simpleDialogDesc + ":",
radioButtons,
cancelButton,voteButton);
}

private JPanel createPane(String description,
JRadioButton[] radioButtons,
JButton cancelButton,voteButton) {
int numChoices = radioButtons.length;
JPanel box = new JPanel();
JLabel label = new JLabel(description);

box.setLayout(new BoxLayout(box, BoxLayout.Y_AXIS));
box.add(label);

for (int i = 0; i < numChoices; i++) {
box.add(radioButtons[i]);
}

JPanel pane = new JPanel();
pane.setLayout(new BorderLayout());
pane.add(box, BorderLayout.NORTH);
pane.add(cancelButton, BorderLayout.SOUTH);
pane.add(voteButton, BorderLayout.SOUTH);
System.out.println("returning pane");
return pane;
}

JButton cancelButton,voteButton) {

you're missing the voteButton type, should be:

private JPanel createPane(String description,
JRadioButton[] radioButtons,
JButton cancelButton, JButton voteButton) {
