public interface Painter

Painter can be used to draw on components backgrounds. The use of this interface allows reuse of a background Painter for various components.

A simple example of a background painter is shown here to draw a circle background:

Painter p = new Painter(cmp) {
    public void paint(Graphics g, Rectangle rect) {
        boolean antiAliased = g.isAntiAliased();
        g.setAntiAliased(true);
        int r = Math.min(rect.getWidth(), rect.getHeight())/2;
        int x = rect.getX() + rect.getWidth()/2 - r;
        int y = rect.getY() + rect.getHeight()/2 - r;
        switch (style) {
            case CircleButtonStrokedDark:
            case CircleButtonStrokedLight: {
                if (cmp.getStyle().getBgTransparency() != 0) {
                    int alpha = cmp.getStyle().getBgTransparency();
                    if (alpha  {
    int x = tf1.getAbsoluteX() + tf1.getWidth();
    int y = tf1.getAbsoluteY();
    x -= warningImage.getWidth() / 2;
    y += (tf1.getHeight() / 2 - warningImage.getHeight() / 2);
    g.drawImage(warningImage, x, y);
});
hi.show();
