gccv::PolyLine::PolyLine | ( | Group * | parent, |
std::list< Point > & | points, | ||
ItemClient * | client = NULL |
||
) |
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.
double gccv::PolyLine::Distance | ( | double | x, |
double | y, | ||
Item ** | item | ||
) | const [virtual] |
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] |
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] |
x | the horizontal deplacement |
y | the vertical deplacement |
Moves the PolyLine.
Reimplemented from gccv::Item.
void gccv::PolyLine::SetPoints | ( | std::list< Point > & | points | ) |
points | the new vertices positions. |
Sets the vertices for the PolyLine instance.
void gccv::PolyLine::UpdateBounds | ( | ) | [protected, virtual] |
Evaluates the PolyLine bounds.
Reimplemented from gccv::Item.
std::list<Point> gccv::PolyLine::m_Points [protected] |
The PolyLine vertices.
