Re: Help with GUI

Here is something I slapped together very quickly, maybe it'll help you get started. As you can see I just used a normal JTextField for the password, but you'll easily be able to replace this with a proper password box. Anyway here it is, good luck.
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
public class guiExample extends JFrame
{
JButton closeBtn, submitBtn, clearBtn;
JTextField unameTxt, passTxt;
public static void main(String[] args)
{
new guiExample().entryGUI();
}
public void entryGUI()
{
Container frmContent = getContentPane();
frmContent.setLayout(new BorderLayout());
//Create the username label and textfield
JPanel userPanel = new JPanel();
JLabel unameLbl = new JLabel("User name");
unameTxt = new JTextField(15);
userPanel.add(unameLbl);
userPanel.add(unameTxt);
//Create the password label and textfield
JPanel passPanel = new JPanel();
JLabel passLbl = new JLabel("Password");
passTxt = new JTextField(15);
passPanel.add(passLbl);
passPanel.add(passTxt);
//Create the buttons
JPanel buttonPanel = new JPanel();
closeBtn = new JButton("Close");
submitBtn = new JButton("Submit");
clearBtn = new JButton("Clear");
closeBtn.addActionListener(new buttonListener());
submitBtn.addActionListener(new buttonListener());
clearBtn.addActionListener(new buttonListener());
buttonPanel.add(closeBtn);
buttonPanel.add(submitBtn);
buttonPanel.add(clearBtn);
frmContent.add(userPanel, BorderLayout.NORTH);
frmContent.add(passPanel);
frmContent.add(buttonPanel, BorderLayout.SOUTH);
setSize(350, 300);
setLocation(50,100);
setVisible(true);
}
public class buttonListener implements ActionListener
{
public void actionPerformed(ActionEvent event)
{
Object source = event.getSource();
if(source == closeBtn)
System.exit(0);
else if(source == submitBtn)
{
//Grab the user's input and compare it to
//something valid
String uname = unameTxt.getText();
String pass = passTxt.getText();
//I guess here you would have to connect to
//a database so the program could
//compare the user's input against all the
//ones contained in the database.
//For now I'll just compare the user's input
//with "scott" and "tiger".
if(uname.equals("scott") & pass.equals("tiger"))
createMain();
}
else if(source == clearBtn)
{
unameTxt.setText("");
passTxt.setText("");
}
}
}
public void createMain()
{
//make the main window
JFrame mainWindow = new JFrame();
mainWindow.setSize(600, 600);
mainWindow.setVisible(true);
//make the entry window invisible, however I guess
//it would be better to close it completely.
setVisible(false);
}
}
