Constructor Detail

DrawingEllipse

public DrawingEllipse(int x1,
              int y1,
              int x2,
              int y2)

This constructs a new DrawingEllipse object. The ellipse is defined by its bounding box coordinates, (x1, y1) and (x2, y2).

Method Detail

resizeObject

public void resizeObject(int x1,
                int y1,
                int x2,
                int y2)

This resizes a DrawingEllipse object. The two bounding box coordinates, (x1, y1) and (x2, y2), that define the ellipse are updated.

Specified by:

resizeObject in class DrawingObject

wasClicked

public boolean wasClicked(int px,
                 int py)

This function determines whether the given point (px, py), where the user has clicked, hits the edge of this ellipse.

Specified by:

wasClicked in class DrawingObject

getBoundingBox

public java.awt.Rectangle getBoundingBox()

This function returns a Bounding Box. A bounding box is the smallest rectangle that contains the ellipse.
