Usage

From source file:Clock.java

public void paintComponent(Graphics g) {
    super.paintComponent(g);
    Color colorRetainer = g.getColor();

    g.setColor(getBackground());// w w  w.ja v  a2s  .  co m
    g.fillRect(0, 0, getWidth(), getHeight());
    getBorder().paintBorder(this, g, 0, 0, getWidth(), getHeight());

    calendar.setTime(new Date()); // get current time
    int hrs = calendar.get(Calendar.HOUR_OF_DAY);
    int min = calendar.get(Calendar.MINUTE);

        String time = "" + hrs + ":" + min;
        g.setFont(getFont());
        FontMetrics fm = g.getFontMetrics();
