    Default Simulate button pressed for a Dialog

    Simulate button pressed for a Dialog


    I have crated a Dialog via MessageBox (prompt method) and added a KeyListener to the TextField.
    How can I simulate the pressed of button OK?
    The onButtonPressed method of Dialog is protected...

    Code:
    public static MessageBox promptMessage(String title, String message,
                                       Listener<MessageBoxEvent> callback) {
    final MessageBox box = MessageBox.prompt(title, message, callback);
    
    final Button okButton = box.getDialog().getButtonById(Dialog.OK);
    okButton.disable();
    
    final TextField<String> textBox = box.getTextBox();
    textBox.addKeyListener(new KeyListener() {
    
        @Override
        public void componentKeyPress(ComponentEvent event) {
            if (okButton.isEnabled()
                    && event.getKeyCode() == KeyCodes.KEY_ENTER) {
                box.close();
            }
        }
    });
    
    box.addListener(Events.OnKeyUp, new Listener<MessageBoxEvent>() {
    
        @Override
        public void handleEvent(MessageBoxEvent be) {
            String value = textBox.getValue();
            if (value == null || value.trim().equals("")) {
                okButton.disable();
            } else {
                okButton.enable();
            }
        }
    });
    return box;
    }

    Why would you like to simulate it? Cannot you use

    box.getDialog().hide(okButton);
