Question

I am having trouble getting my JButton to generate images to match my randomized text. I have an ActionListener set up but my but cannot figure out how to get it to access variables in another class. See my work below:

\myJPanel6.java
//import java.awt.event.ActionListener;
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;

public class myJPanel6 extends JPanel implements ActionListener
{
myJButton b1,b2;
        JLabel l1,l2, l3, l4;
public myJPanel6()
{

          setLayout(new GridLayout(1,1));
//=====================================
  student st1 = new student("Michael", "Robinson", 20);
//=====================================
  b1 = new myJButton(st1.getName());
  b1.addActionListener(this);
                add(b1);
//=====================================
            b2 = new myJButton(st1.WhatIsUp());
//    ImageIcon imagereading = new ImageIcon("images/reading.jpg");
      add(b2);
//=====================================

    ImageIcon imagereading = new ImageIcon("images/reading.jpg");
         l1 = new JLabel(imagereading);
       add(l1);
//=====================================
        ImageIcon imagetalking = new ImageIcon("images/talking.jpg");
        l2 = new JLabel(imagetalking);
        add(l2);
//=====================================
        ImageIcon imageinteracting = new ImageIcon("images/interacting.jpg");
        l3 = new JLabel(imageinteracting);
                add(l3);
//========================================
   //      l4 = new JLabel(".......");
     //    add(l4);
}
@Override
public void actionPerformed(ActionEvent event)
        {
            Object obj = event.getSource();
//=====================================
           // If(obj == b1);
//if (obj == b2){l1.setText("-"+b1.getText()+"- was clicked");}
          // l1.setText("button was clicked");
                              if (obj == b2){l1.setImage(l1.getImage());}

}

}

\student.java
import javax.swing.ImageIcon;
import javax.swing.JLabel;

class student
{
//---------Declaring attributes----
String firstName;
String lastName;
int age;
String status;
//------------------------------
    private Object b2;
    private Object reading;

//----------Constrcutor------------
public student(String a, String b, int c)
{
  firstName = a;
  lastName = b;
  age = c;
  if(age<=25) status = "Traditional";
  else status = "Non-Traditional";
}

//---------------------------------

//---------- METHODS --------

String getName()
{
  return("NAME = "+firstName+ " "+lastName + ", Age = "+age+", Status = "+status);
}

int getAge()
{
  return age;
}

String getStatus()
{
  return status;
}

String WhatIsUp()
{
  String b = "dunno";
  double r = Math.random();
  int myNumber = (int)(r*3f);
  if (myNumber == 0) b = "reading";

           //     JLabel MyImage = new JLabel(new ImageIcon("images/reading.jpg"));
                if (myNumber == 1) b = "talking";
                {
            ImageIcon imagetalking;
         //   imagetalking = new ImageIcon("images/talking.jpg");

        }
  if (myNumber == 2) b = "interacting";
                 ImageIcon imageinteracting = new ImageIcon("images/interacting.jpg");
  return b;
}
//--------------------------------------------

Explanation / Answer

you can try this code

public class MyJPanel6 extends Action listener

{

private final File FILECLOSEBUTTON = new File("img\boutonrondX.png"); //My round button with transparent corners

private JButton closeButton = new JButton(); //Creating it empty to be able to place it and resize the image after the button size is known

public MyJPanel6() throws IOException

{

setLayout(null);

setSize(150, 150);

closeButton.setSize(100, 100);

closeButton.setContentAreaFilled(false);

closeButton.setBorderPainted(false);

add(closeButton);

closeButton.addMouseListener(new MouseListener()

{

public void mouseClicked(MouseEvent e)

{

}

public void mousePressed(MouseEvent e)

{

}

public void mouseReleased(MouseEvent e)

{

System.out.println("Alpha value of pixel (" + e.getX() + ", " + e.getY() + ") is: " + clickAlphaValue(closeButton.getIcon(), e.getX(), e.getY()));

}

public void mouseEntered(MouseEvent e)

{

}

public void mouseExited(MouseEvent e)

{

}

});

Image imgCloseButton = ImageIO.read(FILECLOSEBUTTON);

//Resize the image to fit the button

Image newImg = imgCloseButton.getScaledInstance((int)closeButton.getSize().getWidth(), (int)closeButton.getSize().getHeight(), java.awt.Image.SCALE_SMOOTH);

closeButton.setIcon(new ImageIcon(newImg));

}

private int clickAlphaValue(Icon icon, int posX, int posY)

{

int width = icon.getIconWidth();

int height = icon.getIconHeight();

BufferedImage tempImage = (BufferedImage)createImage(width, height);

Graphics2D g = tempImage.createGraphics();

icon.paintIcon(null, g, 0, 0);

g.dispose();

int alpha = (tempImage.getRGB(posX, posY) >> 24) & 0x000000FF;

return alpha;

}

public static void main(String[] args)

{

try

{

MyJPanel6 myJPanel6 = new MyJPanel6();

myJPanel6.setVisible(true);

myJPanel6.setDefaultCloseOperation(Action listener.EXIT_ON_CLOSE);

}

catch(IOException ioe)

{

ioe.printStackTrace();

}
