Detailed Description

Rectangles.

Implements rectangular, optionally filled, items.

Definition at line 39 of file rectangle.h.

Constructor & Destructor Documentation

gccv::Rectangle::Rectangle	(	Canvas *	canvas,
		double	x,
		double	y,
		double	width,
		double	height
	)

Parameters

canvas	a Canvas.
x	the top left corner horizontal position.
y	the top left corner vertical position.
width	the rectangle width.
height	the rectangle height.

Creates a new Rectangle sets it as a child of the root Group of canvas.

gccv::Rectangle::Rectangle	(	Group *	parent,
		double	x,
		double	y,
		double	width,
		double	height,
		ItemClient *	client = NULL
	)

Parameters

parent	the Group to which the new Text will be added.
x	the top left corner horizontal position.
y	the top left corner vertical position.
width	the rectangle width.
height	the rectangle height.
client	the ItemClient for the new Text if any.

Creates a new Rectangle inside parent and sets client as its associated ItemClient.

virtual gccv::Rectangle::~Rectangle ( )

virtual

The destructor.

Member Function Documentation

double gccv::Rectangle::Distance ( double  x, double  y, Item **  item  ) const

virtual

Parameters

x	horizontal position
y	vertical position
item	where to store the Item.

Implementation of Item::Distance() for the Rectangle class. Sets item to this.

Reimplemented from gccv::Item.

void gccv::Rectangle::Draw ( cairo_t *  cr, bool  is_vector  ) const

virtual

Parameters

cr	a cairo_t.
is_vector	whether the cairo_t is a vectorial context.

Draws the Rectangle to cr.

Reimplemented from gccv::Item.

Reimplemented in gccv::Text.

void gccv::Rectangle::GetPosition	(	double &	x,
		double &	y
	)		const

Parameters

x	where to store the top left corner horizontal position.
y	where to store the top left corner vertical position.

Retrieves the position the Rectangle.

void gccv::Rectangle::GetPosition	(	double &	x,
		double &	y,
		double &	width,
		double &	height
	)		const

Parameters

x	where to store the top left corner horizontal position.
y	where to store the top left corner vertical position.
width	where to store the rectangle width.
height	where to store the rectangle height.

Retrieves the position and size of the Rectangle.

void gccv::Rectangle::Move ( double  x, double  y  )

virtual

Parameters

x	the horizontal deplacement
y	the vertical deplacement

Moves the Rectangle.

Reimplemented from gccv::Item.
