Java SE (Java Platform, Standard Edition)

im trying to copy the functionality of one of those lame .applet demos
in which you press the mouse button down and a circle appears.
however, this is not an applet but a stand alone swing app.
i tried this two diff ways and it didnt work. here is my super brief code...

there is a main class that has a frame that loads a class that extends JPanel.

public main{
JFrame f = new JFrame
JPanel draw = new Draw();
draw.setOpaque(true);
f.setContentPane(draw);
}

this is another file Draw.class that extends a JPanel

class Plot1d extends JPanel implements MouseMotionListener{

public Plot1d() {
super();
}
public void paint(Graphics g) {
super.paint(g);
Graphics2D g2 = (Graphics2D)g;
}
public void mousePressed(MouseEvent e) {
mX = e.getX();
mY = e.getY();
System.out.println("press");
repaint();
}

obviously a lot is left out. everything is setup correctly and works fine
but none of the mouse events are triggering.
i put the System.out text there to see if maybe it was working but
not repainting.
I also tried this with eventlistener

class EventListener extends MouseAdapter
implements MouseMotionListener{
public void mouseClicked(MouseEvent e) {}
... }

private EventListener eListen;
eListen = new EventListener();

putting those two statments in the right place and without the previous
implements MouseML but that didnt work either.
Any help appreciated thanks!
