Constructor & Destructor Documentation

gccv::Wedge::Wedge	(	Canvas *	canvas,
		double	x0,
		double	y0,
		double	x1,
		double	y1,
		double	width
	)

Parameters

canvas	a Canvas.
x0	the triangle top horizontal position.
y0	the triangle top vertical position.
x1	the horizontal position of the canter of the triangle base.
y1	the vertical position of the canter of the triangle base.
width	the triangle base width.

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

gccv::Wedge::Wedge	(	Group *	parent,
		double	x0,
		double	y0,
		double	x1,
		double	y1,
		double	width,
		ItemClient *	client = `NULL`
	)

Parameters

parent	the Group to which the new Wedge will be added.
x0	the triangle top horizontal position.
y0	the triangle top vertical position.
x1	the horizontal position of the canter of the triangle base.
y1	the vertical position of the canter of the triangle base.
width	the triangle base width.
client	the ItemClient for the new Wedge if any.

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

virtual gccv::Wedge::~Wedge ( )

virtual

The destructor.

Member Function Documentation

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

virtual

Parameters

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

		bool	is_vector
	)		const

virtual

Parameters

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

Draws the Wedge to cr.

Reimplemented from gccv::Item.

Reimplemented in gccv::Hash.

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

virtual

Parameters

x	the horizontal deplacement
y	the vertical deplacement

Moves the Wedge.

Reimplemented from gccv::Item.

void gccv::Wedge::SetPosition	(	double	x0,
		double	y0,

		double	y1
	)

Parameters

x0	the triangle top horizontal position.
y0	the triangle top vertical position.
x1	the horizontal position of the canter of the triangle base.
y1	the vertical position of the canter of the triangle base.

Setes the new position for the Wedge instance.

void gccv::Wedge::UpdateBounds ( )

protectedvirtual

Evaluates the Wedge bounds.

Reimplemented from gccv::Item.
