public abstract class AbstractRectangleShape

extends FilledShape

This provides a basic abstract implementation of rectangular bounded Figures. Although this is an abstract class, it is acknowledged that there are other implementations (e.g. ones that uses Locators) which are more flexible. Therefore, one may wish to consider subclassing the superclass instead. This provides most of its functionality based on a simple x, y, width, height attributes, and forces concrete subclasses to define, at a minimum: paintStrokes(Graphics); paintFilled(Graphics);

Method Detail

basicMove

protected void basicMove(int x,
                         int y)

Moves the receiver to a new location. The x and y coordinates are in the parent's coordinate space.

Overrides:

basicMove in class AbstractFigure

Parameters:

x - the x coordinate

y - the y coordinate

basicReshape

protected void basicReshape(int x,
                            int y,
                            int width,
                            int height)

Reshapes the receiver to the specified bounding box.

Overrides:

basicReshape in class FilledShape

Parameters:

x - the x coordinate

y - the y coordinate

width - the width of the figure

height - the height of the figure

basicResize

protected void basicResize(int width,
                           int height)

Overrides:

basicResize in class AbstractShape

Parameters:

width - the width of the figure

height - the height of the figure

basicTranslate
