Constructor Detail

OverlayEllipse

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

The constructor sets the values for the width, height and the color of the ellipse.

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 the outline of an ellipse.

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 the outline of an ellipse. If the ellipse is animated once and the applet has to be redrawn, the function only draws the ellipse without animating it. The ellipse is animated in approximately half a second drawing 14 degrees of the outline each MillisecondsIterator milli seconds. The animation starts from the upper right corner and goes counter-clockwise.

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
