Hi!

Just add listener of type LoginForm.LoginListener to LoginForm. JavaDocs are there so it should be pretty easy to figure out how it works.

cheers,

        loginBox.addListener(new LoginForm.LoginListener() {
            public void onLogin(LoginForm.LoginEvent event) {
                String pw = event.getLoginParameter("password");
                String username = event.getLoginParameter("username");
                if (pw.equals("1234")) {
                    setUser(username);
                    currentUser.setValue(username);
                    currentUser.getWindow().showNotification(
                            "Logged in user: " + username);
                    getMainWindow().getLayout().replaceComponent(loginBox,
                            mainPanel);
                    el.expand(mainPanel);
                } else {
                    getMainWindow().showNotification(
                            "Wrong password. Hint, try '1234' ",
                            Notification.TYPE_WARNING_MESSAGE);
                }
            }
        });
