Returns the total advance width for showing the specified String in this Font .

Usage

From source file:Main.java

/** Draw 'str' centered at 'p'. */
public static void drawCenteredText(Graphics g, Point p, String str) {
    FontMetrics fm = g.getFontMetrics();
    LineMetrics lm = fm.getLineMetrics(str, g);

    // Go to 'p', then add a/2 to get to the baseline.
    // I ignore the descent because it looks better to center without
    // regard to descenders.
    int baseY = p.y + (int) (lm.getAscent() / 2);
    int baseX = p.x - fm.stringWidth(str) / 2;

    g.drawString(str, baseX, baseY);//from   w w w .j av  a  2 s.c o m
