Graphics2D: create a visible line, read on

[Vinicius Souza]

Hi Im creating an app where I need that a rectangle be visible all the time over the background. So I created this:

	public void paint(Graphics g)
	{
		super.paint(g);	
		Graphics2D g2d = (Graphics2D) g;
		if (true) {
			float[] dash1 = { 2f, 0f, 2f };
			g.setColor(Color.black);
			g.fillRect(0, 0, getWidth(), getHeight());
			g.setColor(Color.white);
			BasicStroke bs1 = new BasicStroke(1, BasicStroke.CAP_BUTT, BasicStroke.JOIN_ROUND, 1.0f, dash1, 2f);
			g2d.setStroke(bs1);
			g2d.drawRect(0, 0, getWidth(), getHeight());
	
		}
	}

But in this example the rectangle is draw using white color. How can I do something like a xor that react with the background color to make this rectangle visible with any background?
Thanks in advance!
