Question

So here is the entire file I am using, and in desperation, I put the x and y to be defined in every event but I still get nothing.. this is a multi-class project, where should I do addMouseListener()? and why isnt this picking up the event? (note: the printing of the coordinates in run() works.) This is an applet project and the applet works fine just doesnt register this event.

public class ClickCheck implements Runnable, java.awt.event.MouseListener {
public int x, y;

public ClickCheck() {

    Thread t = new Thread(this);
    t.start();
}

public void mouseClicked(java.awt.event.MouseEvent ev) {

    x = ev.getX();
    y = ev.getY();
    System.out.println(x + "," + y);
}

public void mousePressed(java.awt.event.MouseEvent ev) {
    x = ev.getX();
    y = ev.getY();
    System.out.println(x + "," + y);
}

public void mouseReleased(java.awt.event.MouseEvent ev) {
    x = ev.getX();
    y = ev.getY();
    System.out.println(x + "," + y);
}

public void mouseEntered(java.awt.event.MouseEvent ev) {
    x = ev.getX();
    y = ev.getY();
    System.out.println(x + "," + y);
}

public void mouseExited(java.awt.event.MouseEvent ev) {
    x = ev.getX();
    y = ev.getY();
    System.out.println(x + "," + y);
}

public void run() {
    System.out.println(x + "," + y);

}
}

Assuming you want to add a MouseListener to the main window/panel area of your applet you would add this to your applet init() method:

public void init()
{
   addMouseListener(new ClickCheck());
   ...

Also it’s very unusual to have Thread included in your MouseListener. The thread itself will print out co-ordinates & exit immediately.
