I am trying to make a sign in program with a time clock display. I am having a hard time trying to get the clock into the already made JPanel. It currently pops up 2 seperate JPanels when I run the program. Please help with any suggestions.
CODE:
private static JLabel lblUserName;
private static JTextField txtUserName;
private static JButton btnSignIn;
private static JLabel lblPassword;
private static JPasswordField txtPassword;
private static JButton btnCancel;
private static JTabbedPane tabbedPane;
public static void main(String[] args)
{
UserSignIn frame = new UserSignIn();
JFrame frm = new JFrame();
SimpleDigitalClock clock1 = new SimpleDigitalClock();
frm.add(clock1);
//Pack
frm.pack();
frame.pack();
// Set origional focus on User Name text field
txtUserName.requestFocusInWindow();
// Make Visible
frame.setVisible(true);
frm.setVisible(true);
}
static class SimpleDigitalClock extends JPanel
{
String stringTime;
int hour, minute, second;
String aHour = "";
String bMinute = "";
String cSecond = "";
public void setStringTime(String abc)
{
this.stringTime = abc;
}
public int Number(int a, int b)
{
return (a <= b) ? a : b;
}
SimpleDigitalClock()
{
Timer t = new Timer(1000, new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
repaint();
}
});
t.start();
}
@Override
public void paintComponent(Graphics v)
{
super.paintComponent(v);
Calendar rite = Calendar.getInstance();
hour = rite.get(Calendar.HOUR_OF_DAY);
minute = rite.get(Calendar.MINUTE);
second = rite.get(Calendar.SECOND);
if (hour < 10)
{
this.aHour = "0";
}
if (hour >= 10)
{
this.aHour = "";
}
if (minute < 10)
{
this.bMinute = "0";
}
if (minute >= 10)
{
this.bMinute = "";
}
if (second < 10)
{
this.cSecond = "0";
}
if (second >= 10)
{
this.cSecond = "";
}
setStringTime(aHour + hour + ":" + bMinute+ minute + ":" + cSecond + second);
v.setColor(Color.RED);
int length = Number(this.getWidth(),this.getHeight());
Font Font1 = new Font("Digital", Font.BOLD, length / 5);
v.setFont(Font1);
v.drawString(stringTime, (int) length/6, length/2);
}
@Override
public Dimension getPreferredSize()
{
return new Dimension(200, 200);
}
}
public UserSignIn()
{
initGUI();
}
public void initGUI()
{
setTitle("Login");
JPanel pnlUserSignIn = new JPanel(new GridBagLayout());
this.getContentPane().add(pnlUserSignIn);
//build table for employees signed in
JTable t = new JTable(null);
JLabel label = new JLabel("Employees Currently Signed In");
// ROW 1 BUTTONS
// Username and Sign In buttons
lblUserName = new JLabel("Username: ");
txtUserName = new JTextField("Username");
// Actions
//txtUserName.addMouseListener(this);
// Adding objects to Panel
JPanel pnlLogin = new JPanel();
pnlLogin.add(lblUserName);
pnlLogin.add(txtUserName);
//ROW 2 BUTTONS
//Password and Cancel
btnSignIn = new JButton("Sign In");
btnCancel=new JButton("Cancel");
//Actions
btnSignIn.addActionListener(this);
btnCancel.addActionListener(this);
// Adding objects to Panel
JPanel pnlPassword = new JPanel();
pnlPassword.add(btnSignIn);
pnlPassword.add(btnCancel);
JPanel detailsPanel = new JPanel();
detailsPanel.setBorder(BorderFactory.createLineBorder(Color.BLACK));
GridBagConstraints gbc = new GridBagConstraints();
// Putting Objects into the grid
gbc.gridx = 0;
gbc.gridy = 0;
pnlUserSignIn.add(label, gbc);
gbc.gridx = 0;
gbc.gridy = 1;
pnlUserSignIn.add(new JScrollPane(t), gbc);

this.pack();
this.setVisible(true);

{
System.exit(0);
}
//if(actionEvent.getSource()==txtUserName)

}
PLEASE IGNORE THE COMMENTED CODE, I am working on many things at once.
You don't need another frame. Just add clock to existing one. For example to the SOUTH:

import java.awt.Color;
import java.awt.Dimension;

public class UserSignIn extends JFrame implements ActionListener{
private static JLabel lblUserName;
private static JTextField txtUserName;

private static JPasswordField txtPassword;
private static JButton btnCancel;
private static JTabbedPane tabbedPane;
public static void main(String[] args) {
UserSignIn frame = new UserSignIn();
SimpleDigitalClock clock1 = new SimpleDigitalClock();
frame.add(clock1, BorderLayout.SOUTH);
// Pack
frame.pack();
// Set origional focus on User Name text field
txtUserName.requestFocusInWindow();
// Make Visible
frame.setVisible(true);
}
