Constructor Detail

OverlayBox

public OverlayBox(int inWidth,
                  int inHeight,
                  java.awt.Color inColor)

The constructor takes values for the width, height and the color of the box.

Parameters:

inWidth - The width of the bounding box of the ellipse

inHeight - The height of the bounding box of the ellipse

inColor - The color of the ellipse

Method Detail

draw

public void draw(java.awt.Graphics g,
                 int x,
                 int y)

Draws a box

Overrides:

draw in class Overlay

Parameters:

g - The graphical context of the applet

x - The x coordinate of the upper left corner the bounding box of the ellipse

y - The y coordinate of the upper left corner the bounding box of the ellipse

animate

public void animate(java.awt.Graphics g,
                    int x,
                    int y)

Animates a box. If the box is animated once and the applet has to be redrawn, the function only draws the box without animating it. The box is animated in approximately one a second drawing four lines, which enclose what the object drawn so far, each MillisecondsIterator milli seconds. The animation starts from the center of the box and the box expands outwards. There are three special cases in the animation. CASE 1: If the height is bigger than the width CASE 2: If the width is bigger than the height CASE 3: if the width and the height are equal.

Overrides:

animate in class Overlay

Parameters:

g - The graphical context of the applet

x - The x coordinate of the upper left corner the bounding box of the ellipse

y - The y coordinate of the upper left corner the bounding box of the ellipse
