## Description

GooCanvasPathModel represents a model for path items, which are a series of one or more lines, bezier curves, or elliptical arcs.

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()`.

GooCanvasPathModel uses the same path specification strings as the Scalable Vector Graphics (SVG) path element. For details see the SVG specification.

To create a GooCanvasPathModel use `goo_canvas_path_model_new()`.

To get or set the properties of an existing GooCanvasPathModel, use `g_object_get()` and `g_object_set()`.

To respond to events such as mouse clicks on the path you must connect to the signal handlers of the corresponding GooCanvasPath objects. (See `goo_canvas_get_item()` and "item-created".)

## Details

### GooCanvasPathModel

    typedef struct _GooCanvasPathModel GooCanvasPathModel;

The GooCanvasPathModel struct contains private data only.

### goo_canvas_path_model_new ()

    GooCanvasItemModel* goo_canvas_path_model_new           (GooCanvasItemModel *parent,
                                                             const gchar *path_data,
                                                             ...);

Creates a new path model.

`parent` : | 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 call `g_object_unref()` to free it.
`path_data` : | the sequence of path commands, specified as a string using the same syntax as in the Scalable Vector Graphics (SVG) path element.
`...` : | optional pairs of property names and values, and a terminating `NULL`.
Returns : | a new path model.

Here's an example showing how to create a red line from (20,20) to (40,40):

     GooCanvasItemModel *path = goo_canvas_path_model_new (mygroup,
                                                           "M 20 20 L 40 40",
                                                           "stroke-color", "red",
                                                           NULL);

This example creates a cubic bezier curve from (20,100) to (100,100) with the control points at (20,50) and (100,50):

     GooCanvasItemModel *path = goo_canvas_path_model_new (mygroup,
                                                           "M20,100 C20,50 100,50 100,100",
                                                           "stroke-color", "blue",
                                                           NULL);

This example uses an elliptical arc to create a filled circle with one quarter missing:

     GooCanvasItemModel *path = goo_canvas_path_model_new (mygroup,
                                                           "M200,500 h-150 a150,150 0 1,0 150,-150 z",
                                                           "fill-color", "red",
                                                           "stroke-color", "blue",
                                                           "line-width", 5.0,
                                                           NULL);
