... draws a filled blue rectangle. Methods fillRoundRect (line 24) and drawRoundRect (line 25) draw rectangles with rounded corners. Their first two arguments specify the coordinates of the upper-left corner of the bounding rectangle—the area in which the rounded rectangle will be drawn. The upper-left corner coordinates are not the edge of the rounded rectangle, but the coordinates where the edge would be if the rectangle had square corners. The third and fourth arguments specify the width and height of the rectangle. The last two arguments determine the horizontal and vertical diameters of the arc (i.e., the arc width and arc height) used to represent the corners.
