[Khalid Ali]

u will need to add following line for every button for it do something

Name1button.addActionListener(this);

once that is done then you will need to define what will it do in the actionPerformed method.

After that u will need to create another class such as person and it should inherit the parent class that u want.

[The One]

i did the first bit.
Then do i copy this(below) but just change the name to the other name i have????
AND 2) How wud i call another class to open up in a new window wen i press a button (see Employee). i wanna call that to open wen i press Bob Carey?

if(e.getSource() instanceof JButton ){
JButton jb = (JButton) e.getSource();
if(jb.getText().equals("Bob Carey")){
openNewFrame("This is a second frame.");
}
}

****************************************************
Do u know how o answer my other quetion in which another employee may be added by simply clickin a button??

[Khalid Ali]

yes copy only this bit


if(jb.getText().equals("Bob Carey")){
openNewFrame("This is a second frame.");
}

[The One]

i did as u said (Below), and changed the nane to Luis Garcia but wen i run the program and press Luis Garcia, nothin happens?


public void actionPerformed(ActionEvent e) {

if(e.getSource() instanceof JButton ){
JButton jb = (JButton) e.getSource();
if(jb.getText().equals("Bob Carey")){
openNewFrame("This is a second frame.");

if(jb.getText().equals("Luis Garcia")){
openNewFrame("This is a second frame.");
}
}
}
}
}

[Khalid Ali]

in addition to that, you need to tell the frame that there is an event capture attached to the button.
Name2button.addActionListener(this);

[The One]

I did all the following,:

JButton Name2button = new JButton("Luis Garcia");
Name2button.setPreferredSize(new Dimension(Button_width, Button_height));
Name2button.addActionListener(this);
.
.
.
.
public void actionPerformed(ActionEvent e) {

if(e.getSource() instanceof JButton ){
JButton jb = (JButton) e.getSource();
if(jb.getText().equals("Bob Carey")){
openNewFrame("This is a second frame.");

if(jb.getText().equals("Luis Garcia")){
openNewFrame("This is a second frame.");
}
}
}
}
}



********
is that all i do? Cos still wen i press Luis Garcia, Nothin Happens????

[Khalid Ali]

u must be doing something wrong...:-)

here is the working example



import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class Salary extends JFrame implements ActionListener{

public Salary(){
int Button_width = 230;
int Button_height = 25;

JLabel IntroLabel = new JLabel(" Welcome to salary sheet");
final JTextField Introtextfield = new JTextField(15);
JLabel Intro2Label = new JLabel("Please select the employee' name that you would like to edit");
final JTextField Intro2textfield = new JTextField(15);

JButton Name1button = new JButton("Bob Carey");
Name1button.setPreferredSize(new Dimension(Button_width, Button_height));
Name1button.addActionListener(this);

JButton Name2button = new JButton("Luis Garcia");
Name2button.setPreferredSize(new Dimension(Button_width, Button_height));
Name2button.addActionListener(this);

JButton Name3button = new JButton("Xavi Alonso");
Name3button.setPreferredSize(new Dimension(Button_width, Button_height));

JButton Name4button = new JButton("Steven Gerrard");
Name4button.setPreferredSize(new Dimension(Button_width, Button_height));

this.setTitle("Salary Sheet");
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Container cframe = this.getContentPane();


cframe.setLayout(new GridLayout(6, 2));
cframe.add(IntroLabel);
cframe.add(Intro2Label);
cframe.add(Name1button);
cframe.add(Name2button);
cframe.add(Name3button);
cframe.add(Name4button);

this.pack();
this.show();
}

public void actionPerformed(ActionEvent e) {

if(e.getSource() instanceof JButton ){
JButton jb = (JButton) e.getSource();
if(jb.getText().equals("Bob Carey")){
openNewFrame("This is a second frame.");
}
if(jb.getText().equals("Luis Garcia")){
openNewFrame("This is a second frame.");
}
}
}

public void openNewFrame(String frameTitle){

JFrame frame = new JFrame(frameTitle);
frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
Container cframe = frame.getContentPane();
frame.setSize(new Dimension(200,200));

frame.show();

public static void main(String [] args) {

new Salary();
