Usage

From source file:Main.java

public void paint(Graphics g) {

    int fontSize = 20;

    Font font = new Font("TimesRoman", Font.PLAIN, fontSize);
    g.setFont(font);//from  w ww .  j a v a  2  s. c o  m

    FontMetrics fm = g.getFontMetrics(font);

    String s = "www.java2s.com";

    int stringWidth = fm.stringWidth(s);

    int w = 200;
    int h = 200;

    int x = (w - stringWidth) / 2;
    int baseline = fm.getMaxAscent() + (h - (fm.getAscent() + fm.getMaxDecent())) / 2;
    int ascent = fm.getMaxAscent();
    int descent = fm.getMaxDecent();
    int fontHeight = fm.getMaxAscent() + fm.getMaxDecent();

    g.setColor(Color.white);
    g.fillRect(x, baseline - ascent, stringWidth, fontHeight);

    g.setColor(Color.gray);
    g.drawLine(x, baseline, x + stringWidth, baseline);

    g.setColor(Color.red);
