I have a problem with my code of a simple game

**byrne** · April 15th, 2012, 10:31 AM

Hello!

I try to do a image in a frame to advance a few pixels to click the image

The problem comes to add the image in a label and I try to call the label in a method addMouseListener() and after Mouseclicked()

The code in which I do it it´s it:

 
/************* This is the part af code where I have the request    *////////////////////////////////////
 
             Ejemplo.getContentPane().add(etiqueta, BorderLayout.CENTER); 
/* 109 */    
              etiqueta.addMouseListener(new MouseAdapter()
/*     */     {
/*     */      public void mouseClicked(MouseEvent paramMouseEvent)
/*     */      {
/* 113 */        System.out.println("pepe");
/* 114 */        Ejemplo.this.sw2 = 1;
/*     */       }
/*     */     });
 
/************* This is the part af code where I have the request    *////////////////////////////////////

etiqueta is a label and adds the label is the image.

This code is in the constructor, in Ejemplo(){}.

in the main class of the java program, in "public class Ejemplo extends JPanel
/* */ implements KeyListener, Runnable
/* */ {"
I put the code of the label, it is:

static ImageIcon imagen1 = new ImageIcon("rectangulovacio.jpg");
static JLabel etiqueta = new JLabel(imagen1);

and the program work, I created the file "Ejemplo.class" but not work the method "MouseClicked" because I click in the image and not happen anything... I can't do the program so? Thanks

So, from what you're saying, you're not getting any error messages. Could you try to re-explain yourself, I can see that english isn't your first language. I also wouldn't mind see a little bit more code.

I don't receive error messages but the program doesn`t do that I want.

I want when the image is clicked it must be advance a pixels inside the frame but the image don't do anything when I click in. It only shows inside the frame, in the center

the complete code of the program is it:
