beginner / mouse listener, ears are plugged

[ed jones]

I've read alot of code on mouse listeners, and I'm still stuck

I've created a rectangle, and when the mouse is inside, and I click, I should see a response in the rectangle, but I don't?

thanks for your time

heres some of the code

import acm.graphics.*;
import acm.program.*;
import acm.util.*;
 
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
 
public class Breakout extends GraphicsProgram  implements MouseListener{
 
int xpos, ypos;
 
public void run() {
setup();
}//run


//setup the inital box
public void setup()
{
 
GRect outsideFrame = new GRect(0,0,WIDTH, HEIGHT);
outsideFrame.addMouseListener(this);
addMouseListener(this);
add(outsideFrame);
         }
 
 
    public void mousePressed(MouseEvent e) { }
       
    public void mouseReleased(MouseEvent e) { }
      
    public void mouseEntered(MouseEvent e) { }
    
    public void mouseExited(MouseEvent e) { }
   
    public void mouseClicked(MouseEvent e) {
    
    xpos = e.getX();
    ypos = e.getY();
    
    repaint();
       
    }
    
    
    public void paint(Graphics g)
    {
    g.drawString("mouse", xpos, ypos);
    
    }
}

I can't see anything wrong with the code.

What you are doing is setting xpos and ypos, but you are not doing anything with them.

Try putting this is your mousePressed() method, press your mouse, and see what happens

System.out.printf("x = %d, y = %d%n", e.getX(), e.getY());

Please find the code button and use tags to maintain your indentation. This sort of thing is usually discussed in the Swing forum, so I think I ought to move you there.

a lot depends on what your classes are i.e. components etc.
assuming they are, the program is unlikely to print anything that can be seen.

you add a mouseListener to outsideFrame
you also add the mouseListener to 'extends GraphicsProgram' (whatever that is)
then you add outsideFrame to 'extends GraphicsProgram'

so the mouse will be clicking outsideFrame, but repaint() and paint()
belong to 'extends GraphicsProgram' which is perhaps covered by outsideFrame
