The following applet that I have displays a house with two windows and a door that are colored in black. I want to display these items with window panes in them to show that they are open when the user clicks on them. I know that I need to use a MouseListener that repaints to do so, but do not understand how to set the right coordinates to make that possible...

// Set the background color to white.
getContentPane().setBackground(Color.WHITE);
}
public void paint(Graphics g)
{
super.paint(g);
g.setColor(Color.BLUE);
g.fillRect(5, 5 , 200, 150);
g.setColor(Color.BLACK);
g.fillRect(20,40,35,35);
g.setColor(Color.BLACK);
g.fillRect(140,40,35,35);
g.setColor(Color.BLACK);
g.fillRect(75,75,50,80);
}
