Fill in rectangle partially (clip?¿)

[OBLITERATOR]

Hello, I've searched the forum and I couldn't find any answers so here's my problem:

I have to partially fill in a rectangle, i'll express the idea using O's:

OOOOO
O-O- O
OOOOO
O----O

(-= white "squares/areas")

more or less, basically I leave out certain white areas here's my code:

import javax.swing.*;
import java.awt.*;

public class Drawing{
  public static void main(String[] args) {
    Drawing d = new Drawing();
  }

  public Color(){
    JFrame frame = new JFrame("faces");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.getContentPane().add(new MyComponent());
    frame.setSize(800,600);
    frame.setVisible(true);  
  }

  public class MyComponent extends JComponent{
    public void paint(Graphics g){
      int height;
      int width;
      g.clipRect(1,1,50,40);
      g.setColor(Color.black);
      g.fillRect(1,1,10,40);
      g.fillRect(2,1,50,10);
      //g.fillRect(6,2,50,20);
    }
  }
}

the two g.fillRect lines that are NOT commented out fill in the first collumn and first row respectively, however I cant manage to fill a different row (3rd)....
(and individual squares within a given row column)

Any ideas?

pd g.clipRect(1,1,50,40) making the start coords 0,0 doesnt seem to make any difference...

You'll have to divide your rectangle into a grid of rectangles, and paint the spaces in that grid that you want painted. Probably a 2D array of something like GridPoint that you can activate/deactivate depending on whether you want it filled or not(or it tracks its own color) and also give it a draw/paint method.
