Greetings,
I am developping a gui application. In my toolbar I would like to have a menu button which opens a frame which prompts user for various "account settings" values and then return them to the main window.
What is the best way to approach this?
I have the following code, but my getter methods are always returning null for some reason
Thanks.
// SAMPLE FROM MAIN CLASS .......
private String username = "";
private String password = "";
JMenuItem miAccountSettings = new JMenuItem("Account Info");
miAccountSettings.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
AccountSettings accountSettings = new AccountSettings();
username = accountSettings.getUsername();
password = accountSettings.getPassword();
}
});
optionsMenu.add(miAccountSettings);
// AccountSettings CLASS
public class AccountSettings implements ActionListener {
private String username;
private String password;
private JTextField txtUser;
private JPasswordField txtPass;
private JButton btnSave;
private JButton btnCancel;
private JFrame f;
public AccountSettings() {
f = new JFrame();
f.setTitle("Account Info");
Toolkit kit = f.getToolkit();
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice[] gs = ge.getScreenDevices();
Insets in = kit.getScreenInsets(gs[0].getDefaultConfiguration());
Dimension d = kit.getScreenSize();
int max_width = (d.width - in.left - in.right);
int max_height = (d.height - in.top - in.bottom);
f.setSize(Math.min(max_width, 400), Math.min(max_height, 250));
f.setLocation((int) (max_width - f.getWidth()) / 2, (int) (max_height - f.getHeight() ) / 2);
