How to close a JFrame in the middle of a program
- by Nick Gibson
public class JFrameWithPanel extends JFrame implements ActionListener, ItemListener
{
int packageIndex;
double price;
double[] prices = {49.99, 39.99, 34.99, 99.99};
DecimalFormat money = new DecimalFormat("$0.00");
JLabel priceLabel = new JLabel("Total Price: "+price);
JButton button = new JButton("Check Price");
JComboBox packageChoice = new JComboBox();
JPanel pane = new JPanel();
TextField text = new TextField(5);
JButton accept = new JButton("Accept");
JButton decline = new JButton("Decline");
JCheckBox serviceTerms = new JCheckBox("I Agree to the Terms of Service.", false);
JTextArea termsOfService = new JTextArea("This is a text area", 5, 10);
public JFrameWithPanel()
{
super("JFrame with Panel");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
pane.add(packageChoice);
setContentPane(pane);
setSize(250,250);
setVisible(true);
packageChoice.addItem("A+ Certification");
packageChoice.addItem("Network+ Certification ");
packageChoice.addItem("Security+ Certifictation");
packageChoice.addItem("CIT Full Test Package");
pane.add(button);
button.addActionListener(this);
pane.add(text);
text.setEditable(false);
text.setBackground(Color.WHITE);
text.addActionListener(this);
pane.add(termsOfService);
termsOfService.setEditable(false);
termsOfService.setBackground(Color.lightGray);
pane.add(serviceTerms);
serviceTerms.addItemListener(this);
pane.add(accept);
accept.addActionListener(this);
pane.add(decline);
decline.addActionListener(this);
}
public void actionPerformed(ActionEvent e)
{
packageIndex = packageChoice.getSelectedIndex();
price = prices[packageIndex];
text.setText("$"+price);
Object source = e.getSource();
if(source == accept)
{
if(serviceTerms.isSelected() == false)
{
JOptionPane.showMessageDialog(null,"Please accept the terms of service.", "Terms of Service", JOptionPane.ERROR_MESSAGE);
}
else
{
JOptionPane.showMessageDialog(null,"Thank you. We will now move on to registering your product.");
pane.dispose();
}
}
else if(source == decline)
{
System.exit(0);
}
}
public void itemStateChanged(ItemEvent e)
{
int select = e.getStateChange();
}
public static void main(String[] args)
{
String value1;
int constant = 1, invalidNum = 0, answerParse, packNum, packPrice;
JOptionPane.showMessageDialog(null,"Hello!"+"\nWelcome to the CIT Test Program.");
JOptionPane.showMessageDialog(null,"IT WORKS!");
}
}//class
How do I get this frame to close so that my JOptionPane Message Dialogs can continue in the program without me exiting the program completely.
EDIT: I tried .dispose() but I get this:
cannot find symbol
symbol : method dispose()
location: class javax.swing.JPanel
pane.dispose();
