after
void drawRect(int top, int left, int width, int height)
call
fillRect(int top, int left, int width, int height

eg,
if you want to have rect(100*50) of width 5

call

c1.drawRect(10, 10, 100, 50)
c2.fillRect(10, 10, 100, 50)
c1.fillRect(15, 15, 90, 40)

(where c1 and c2 are "black" and "red" color)


This will work for you.

Hi pipe...
Do you mean the thickness of the line? I don't think you can set it.  You can do this instead.

        int thickNess = 4;
        for (int i = 0; i < thickNess; i++)
            g.drawRect(x + i, y + i, width - 2 * i, height - 2 * i);

regards..

Actually, if you use Graphics2D, you can adjust the thickness

public void paint(Graphics g){
  BasicStroke stroke = new BasicStroke(5); //5 pixels wide
  Graphics2D g2 = (Graphics2D) g;
  g2.setStroke(stroke);
  g2.drawRect(w,x,y,z);
  ...
}

the possible option is using drawRect() for straight lines only.

public void paint(Graphics g)
{
   g.drawRect(int a, int b, widht w, height h);
}

a and b are the co-ordinates

w is the length of the line

h is the thickness
