GooCanvasPolylineModel represents a model for polyline items, which are a series of one or more lines, with optional arrows at either end.
It is a subclass of GooCanvasItemModelSimple and so inherits all of the style properties such as "stroke-color", "fill-color" and "line-width".
It also implements the GooCanvasItemModel interface, so you can use the
GooCanvasItemModel functions such as goo_canvas_item_model_raise() and
goo_canvas_item_model_rotate().
To create a GooCanvasPolylineModel use goo_canvas_polyline_model_new(), or
goo_canvas_polyline_model_new_line() for a simple line between two points.
To get or set the properties of an existing GooCanvasPolylineModel, use
g_object_get() and g_object_set().
To respond to events such as mouse clicks on the polyline you must connect
to the signal handlers of the corresponding GooCanvasPolyline objects.
(See goo_canvas_get_item() and "item-created".)
struct GooCanvasPolylineModel;
The GooCanvasPolylineModel struct contains private data only.
GooCanvasItemModel * goo_canvas_polyline_model_new (GooCanvasItemModel *parent,gboolean close_path,gint num_points,...);
Creates a new polyline model.
| 
 | the parent model, or NULL. If a parent is specified, it will
assume ownership of the item, and the item will automatically be freed when
it is removed from the parent. Otherwise callg_object_unref()to free it. [skip] | 
| 
 | if the last point should be connected to the first. | 
| 
 | the number of points in the polyline. | 
| 
 | the pairs of coordinates for each point in the line, followed by
optional pairs of property names and values, and a terminating NULL. | 
| Returns : | a new polyline model. [transfer full] | 
Here's an example showing how to create a filled triangle with vertices at (100,100), (300,100), and (200,300).

GooCanvasItemModel * goo_canvas_polyline_model_new_line (GooCanvasItemModel *parent,gdouble x1,gdouble y1,gdouble x2,gdouble y2,...);
Creates a new polyline model with a single line.
