Detailed Description

Multi-segments line.

Line item with several linear segments.

Definition at line 41 of file poly-line.h.

Constructor & Destructor Documentation

gccv::PolyLine::PolyLine	(	Canvas *	canvas,
		std::list< Point > &	points
	)

Parameters

canvas	a Canvas.
points	the vertices positions.

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

gccv::PolyLine::PolyLine	(	Group *	parent,
		std::list< Point > &	points,
		ItemClient *	client = NULL
	)

Parameters

parent	the Group to which the new PolyLine will be added.
points	the vertices positions.
client	the ItemClient for the new PolyLine if any.

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

virtual gccv::PolyLine::~PolyLine ( )

virtual

The destructor.

Member Function Documentation

double gccv::PolyLine::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 PolyLine class. Sets item to this.

Reimplemented from gccv::Item.

void gccv::PolyLine::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 PolyLine to cr.

Reimplemented from gccv::Item.

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

virtual

Parameters

x	the horizontal deplacement
y	the vertical deplacement

Moves the PolyLine.

Reimplemented from gccv::Item.

void gccv::PolyLine::SetPoints

(

std::list< Point > &

points

)

Parameters

points

the new vertices positions.

Sets the vertices for the PolyLine instance.

void gccv::PolyLine::UpdateBounds ( )

protectedvirtual

Evaluates the PolyLine bounds.

Reimplemented from gccv::Item.
