I'm having some fundamental issues with some basic abstraction. Here is the super class:
public abstract class Tile extends JLabel implements MouseListener {
public Tile() {
setIcon(new ImageIcon(getClass().getResource("images/blank.gif")));
}
@Override
public void mousePressed(MouseEvent e) {
System.out.println("clicked");
switch(e.getModifiers()) {
case InputEvent.BUTTON1_MASK: leftClick(); break;
case InputEvent.BUTTON2_MASK: rightClick(); break;
}
}
public abstract void leftClick();
public abstract void rightClick();
}sub class:
public class Mine extends Tile {
@Override
public void leftClick() {
System.out.println("left clicked");
}
@Override
public void rightClick() {
System.out.println("right clicked");
}
}When I implement this on a JFrame, the image is visible, but the MouseListener is not triggering. I tried just using a generic JLabel and adding an inner MouseListener class, which works perfectly. For some reason, I can't get this to work using abstraction, however. Any ideas?
If I understand correctly, the below snippet is essentially the same thing as I implemented with abstraction.
JLabel label = new JLabel(new ImageIcon(getClass()
.getResource("images/blank.gif")));
label.addMouseListener(new MouseListener() {
@Override
public void mousePressed(MouseEvent e) {
System.out.println("click");
}
});
