e587. filling basic shapes.txt

这里面包含了一百多个JAVA源文件

There are two ways to fill basic shapes like lines and rectangles. The first is to use specific drawing methods like Graphics.fillOval(). This example uses these methods. The second is to construct a shape and then use Graphics2D.fill() to fill the shape. See the java.awt.geom package for examples that create shapes. 
    
g2d.fillArc(x, y, w, h, startAngle, arcAngle);
    g2d.fillOval(x, y, w, h);
    g2d.fillRect(x, y, w, h);
    g2d.fillRoundRect(x, y, w, h, arcWidth, arcHeight);
    
    Polygon polygon = new Polygon();
    polygon.addPoint(x, y);
    // ...continue adding points
    g2d.fillPolygon(polygon);
