Usage

From source file:Main.java

@Override
protected void paintComponent(Graphics g) {
    super.paintComponent(g);
    Graphics2D g2d = (Graphics2D) g.create();
    String text = "I don't see the problem";
    FontMetrics fm = g2d.getFontMetrics();
    int x = (getWidth() - fm.stringWidth(text)) / 2;
    int y = ((getHeight() - fm.getHeight()) / 2) + fm.getDescent();
    g2d.setTransform(AffineTransform.getRotateInstance(Math.toRadians(45), getWidth() / 2, getHeight() / 2));
    g2d.drawString(text, x, y);/* w  ww . j ava  2 s  .c  o m*/
