Adding ActionListener, Where am I wrong?
Hello,
Please see the two java files that are working fine, but I need to add actionlisteners to RectangleButton.java file, Could any one please help me? Getting text from textfield of superclass into the a string in the sub-class is my problem.
1st File

import java.applet.*;
public class RectangleButton extends Applet //implements ActionListener
{
TextField tf1,tf2,tf3,tf4;
Label l1,l2,l3,l4;
//Button submit;
public void init()
{
//setLayout(new BorderLayout());
//setLayout(null);
tf1 = new TextField(20);
tf2 = new TextField(20);
tf3 = new TextField(20);
tf4 = new TextField(20);
//submit = new Button("Submit");
add(l1 = new Label("UserName:"));
add(l2 = new Label("Password:"));
add(l3 = new Label("Name:"));
add(l4 = new Label("Age:"));
l1.setBounds(10,20,65,10);
l2.setBounds(10,50,65,10);
l3.setBounds(10,80,65,10);
l4.setBounds(10,110,65,18);
tf1.setBounds(90,15,170,25);
tf2.setBounds(90,45,170,25);
tf3.setBounds(90,75,170,25);
tf4.setBounds(90,105,170,25);
add(tf1);
add(tf2);
add(tf3);
add(tf4);
//add(submit);
RectangleButton2 button1 = new RectangleButton2("Submit");
add(button1);
SimpleActionListener listener = new SimpleActionListener();
button1.addActionListener(listener);
//submit.addActionListener(listener);
}
}
class SimpleActionListener implements ActionListener
{
//TextField tf1;
RectangleButton rectbutton = new RectangleButton();
public SimpleActionListener(){ }
public void actionPerformed(ActionEvent ae)
{
/*if(ae.getActionCommand().equalsIgnoreCase("button1"))
{
String st1 = rectbutton.tf1.getText();
//System.out.println("Clicked:" +ae.getActionCommand());
System.out.println(st1);
}*/
System.out.println("Clicked:" +ae.getActionCommand());
if(ae.getSource() == ("Submit"))
{
String st1 = rectbutton.tf1.getText();
System.out.println("Name = :"+st1);
}
}
}
