- by Ams
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();
}
}
