Hello everyone,

I try to show a ( Logged in ) message when a user is succefully connected but nothing happen when a do a repaint(). you can take a look to the code :

public class MainFrame extends JFrame implements ActionListener{

private static final long serialVersionUID = 1L;
private static final int FRAME_HEIGHT = 400;
private static final int FRAME_WIDTH = 250;
private static final String TITLE = new String("TweeX");
private static String TWITTERID = new String();
private static String TWITTERPW = new String();
private boolean logged = false;
private JTextField loginField = new JTextField(10);
private JPasswordField passField = new JPasswordField(10);
private JButton login = new JButton("Connect");
private GridBagConstraints c = new GridBagConstraints();
private String UserStatus = new String("Please login...");

/*
 * Constructor ! 
 */
MainFrame() {

    setSize(FRAME_WIDTH, FRAME_HEIGHT);
    setTitle(TITLE);
    setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
    setResizable(false);
    loginUser();    
}

/*
 * Login Forms
 */
protected void loginUser(){

    this.setLayout(new GridBagLayout());

    //add Login Fiels + Label
    c.fill = GridBagConstraints.HORIZONTAL;
    c.gridx = 0;
    c.insets = new Insets(5,5,5,20);
    c.gridy = 0;
    add(new JLabel("Username:"),c);

    c.fill = GridBagConstraints.HORIZONTAL;
    c.gridx = 1;
    c.gridy = 0;
    add(loginField,c);

    //add Password Fiels + Label
    c.fill = GridBagConstraints.HORIZONTAL;
    c.gridx = 0;
    c.gridy = 1;
    add(new JLabel("Password:"),c);

    c.fill = GridBagConstraints.HORIZONTAL;
    c.gridx = 1;
    c.gridy = 1;
    add(passField,c);   

    //add Login button
    c.fill = GridBagConstraints.HORIZONTAL;
    c.gridx = 1;
    c.gridy = 2;
    add(login,c);

    //add listener to login button
    login.addActionListener((ActionListener) this);
    c.fill = GridBagConstraints.HORIZONTAL;
    c.gridx = 1;
    c.gridy = 3;
    add(new JLabel(UserStatus),c);
    setVisible(true);
}

@Override
public void actionPerformed(ActionEvent e) {

    TWITTERID = loginField.getText();
    TWITTERPW = passField.getText();
    Twitter twitter = new TwitterFactory().getInstance(TWITTERID,TWITTERPW);
    logged = true;

    try {
        twitter.verifyCredentials();

    } catch (TwitterException e1) {
        logged = false;
    }

} 
protected void connect(){
    if(logged){
        UserStatus = "Loged In :)";
        repaint();
    }
}

static public void main(String[] argv)
{
      new MainFrame();
}

}
