Thread: Graphics mayhem

To draw a rectangular outline:

public void paint(Graphics g)
{
    g.drawRect(x, y, width, height);
}

To draw a polygon outline:

Polygon p = new Polygon();
p.addPoint(x,y);
// .. add as many points as you want
// g is a Graphics object
g.drawPolygon(p);

To override the paint method safely:

make sure you call the super class's paint method before you do any extra painting.

public void paint(Graphics g)
{
    super.paint(g);
    // your painting
}

In general, try to not override the paint method directly. See if you can override the paintComponent() method (make sure to call super.paintComponent() if the base class had some painting going on inside paintComponent()).
