Question

How could i go about adding more containers to my Jframe? Heres my line of code, I would like to make a clock in one window that contains other clocks in side of the same jframe, heres my code:

 import java.awt.*;
 import java.awt.event.*;
 import javax.swing.*;
 import java.util.Calendar;  
 public class CopyOftheclock {
public static void main(String[] args) {
    JFrame clock = new TextClockWindow();
    clock.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    clock.setVisible(true);
     }
}


 @SuppressWarnings("serial")
 class TextClockWindow extends JFrame {
 private JTextField timeField;
   public TextClockWindow() {
    timeField = new JTextField(7);
    timeField.setFont(new Font("sansserif", Font.PLAIN, 48));

    Container content = this.getContentPane();
    content.setLayout(new FlowLayout());
    content.add(timeField); 

    this.setTitle("Norway");
    this.pack();
    javax.swing.Timer t = new javax.swing.Timer(1000,
          new ActionListener() {
              public void actionPerformed(ActionEvent e) {
                  String a = "";
                  Calendar now = Calendar.getInstance();
                  int h = now.get(Calendar.HOUR_OF_DAY);
                    if (h==24)
                    {
                        h=8;
                        a = "A.M";
                    }
                    if (h==1)
                    {

          });
    t.start();

 }

If you guys could help me get this to work i would really appreciate it!

Answer 1

1) For displaying non-editable, text use JLabel rather than JTextField.

2) For less code, use the methods of SimpleDateFormat.

3) Use proper LayoutManager; in your case (maybe) GridLayout would let all JComponent have the same Dimension on the screen.

4) All GUI related code in the main public static void main(String[] args) { should be wrapped into invokeLater(); more in Initial Threads.

5) Maybe for the rest this thread could be useful.
