Thread: Action Listener

Hi Everyone,
I am writing this program to display this GUI with buttons ,I am trying to add an action listener to add functionality to the buttons.

Problem:I am trying to display the colour of the buttons as in (i.e. When a blue button is clicked a blue rectangle is displayed in the center pane)

Now I have managed to draw the rectangle on the center pane but when I add the action Listener to the button it does not compile it generates two errors.

Can someone have a look at my code please , i dont know how to call the paint function into the Listener

errors:

shape.java:43:cannot find symbol
symbol: method setColor(java.awt.Color)
location: class MyPanel
disp.setColor(Color.red)

shape.java:43:cannot find symbol
symbol: method fillRectr(int,int,int,int)
location: class MyPanel
disp.fillRectr(100,50,100,50)

code:

shape.java
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
 
 
 
class shape extends JFrame{
 
      JButton b1 = new JButton("Red");
      JButton b2 = new JButton("Green");
      JButton b3 = new JButton("Blue");
      JButton b4 = new JButton("Black");
      JButton b5 = new JButton("Erase"); 
 
  JPanel east = new JPanel();
  MyPanel disp = new MyPanel();
  JPanel center = new JPanel();
 
 
  shape(){
 
     setupGUI();
     setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
   }
 
   private void setupGUI(){
 
   Container cp = getContentPane();
   cp.setLayout(new BorderLayout());
   cp.add(BorderLayout.CENTER,disp);
   cp.add(disp);
   cp.add(BorderLayout.EAST,east);
   east.setLayout(new GridLayout(5,1));
   east.add(b1);
   east.add(b2);
   east.add(b3);
   east.add(b4);
   east.add(b5);
   b1.addActionListener(new ActionListener(){
       public void actionPerformed(ActionEvent e){
         if(e.getActionCommand().equals("RED")){
 
             disp.setColor(Color.red);
             disp.fillRect(100,50,100,50);
 
 
          //setColor(Color.red);
          //fillRect(100,50,100,50);
 
 
         }
       }
 
    });
   setSize(350,450);
   setVisible(true);
 
  }
  public static void main(String args[]){
 
     shape Pane = new shape();
 
 
 
   }
}

MyPanel.java

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
 
 
class MyPanel extends JPanel{
 
   public void paintComponent(Graphics g){
 
     super.paintComponent(g);
     g.setColor(Color.white);
     g.drawRect(100,50,100,50);
     g.fillRect(100,50,100,50);
 
   }
 
 
}

HI kray66 i just take a look u'r code and how its means that ju called directly the method setColor or setSize from the object MyPanel ,u must inicialize a graphics pen graphics2d a=..... a.setColor...I'would look and one more time to unsure that that was a problem.All wishes
