Constructor & Destructor Documentation

Rectangle

(

)

Constructs an empty rectangle.

The position is 0,0 and the size is 0,0.

Rectangle	(	const Point_2D &	position,
		const Size_2D &	size
	)

Constructs a rectangle from a position and a size.

Parameters:

	position	A Point_2D.
	size	A Size_2D.

Rectangle

(

const Size_2D &

size

)

Constructs a rectangle from a size at position 0,0.

Parameters:

size

A Size_2D.

Rectangle	(	const int	x,
		const int	y,
		const unsigned int	width = 0,
		const unsigned int	height = 0
	)

Constructs a rectangle from an x,y position and width,height size.

Parameters:

	x	The horizontal (x-axis) position.
	y	The vertical (y-axis) position.
	width	The width of the rectangle size.
	height	The height of the recangle size.

Rectangle

(

const Rectangle &

rectangle

)

Constructs a rectangle as a copy of another rectangle.

Parameters:

rectangle

A Rectangle to be copied.

Member Function Documentation

Rectangle & operator=

(

const Rectangle &

rectangle

)

Assign the position and size of another rectangle to this rectangle.

Parameters:

rectangle

A Rectangle whose position and size are be assigned to this rectangle.

Returns:

This Rectangle.

Point_2D position

(

)

const [inline]

Get the rectangle position.

Returns:

A Point_2D with the rectangle position. N.B.: Changing this point will not change the position of the rectangle.

Rectangle& position

(

const Point_2D &

point

)

[inline]

Set the position of the rectangle.

Parameters:

point

A Point_2D for the position of the rectangle.

Returns:

This Rectangle.

Rectangle& position	(	const int	x,
		const int	y
	)			[inline]

Set the x,y position of the rectangle.

Parameters:

	x	The horizontal (x-axis) position.
	y	The vertical (y-axis) position.

Returns:

This Rectangle.

Size_2D size

(

)

const [inline]

Get the rectangle size.

Returns:

A Size_2D with the rectangle size. N.B.: Changing this size will not change the size of the rectangle.

Rectangle& size

(

const Size_2D &

size

)

[inline]

Set the size of the rectangle.

Parameters:

size

A Size_2D for the size of the rectangle.

Returns:

This Rectangle.

Rectangle& size	(	const unsigned int	width,
		const unsigned int	height
	)			[inline]

Set the width,height of the rectangle.

Parameters:

	width	The width of the rectangle size.
	height	The height of the recangle size.

Returns:

This Rectangle.

Rectangle & operator &=

(

const Rectangle &

rectangle

)

Take the intersection with another rectangle.

Parameters:

rectangle

The Rectangle to intersect with this Rectangle.

Returns:

This Rectangle with its position and size set to the intersection with the other rectangle. If the rectangles do not intersect this will result in a rectangle with no area (width and height both zero) but the position will be unchanged.
