Detailed Description

Equilateral hashed triangle.

Equilateral triangle filled with regularly spaced hashes parallel to the triangle base.

Definition at line 40 of file hash.h.

Constructor & Destructor Documentation

gccv::Hash::Hash	(	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 Hash and sets it as a child of the root Group of canvas.

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

Parameters

parent	the Group to which the new Hash 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 Hash if any.

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

virtual gccv::Hash::~Hash ( )

virtual

The destructor.

Member Function Documentation

void gccv::Hash::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 Hash to cr.

Reimplemented from gccv::Wedge.

gccv::Hash::GetLineDist ( void  ) const

inline

Returns

the distance between two consecutive hashes.

Definition at line 99 of file hash.h.

gccv::Hash::GetLineWidth ( void  ) const

inline

Returns

the width of the hashes.

Definition at line 89 of file hash.h.

gccv::Hash::SetLineDist ( double  dist )

inline

Parameters

dist	the new hash distance.

Sets the distance between two consecutive hashes. The periodicity is actually the sum of this distance and the hash width.

Definition at line 99 of file hash.h.

gccv::Hash::SetLineWidth ( double  width )

inline

Parameters

width

the new hash width.

Sets the width of the hashes.

Definition at line 89 of file hash.h.
