<a name="GooCanvasPathModel.description"></a><h2>Description</h2>
<p>
GooCanvasPathModel represents a model for path items, which are a series of
one or more lines, bezier curves, or elliptical arcs.
</p>
<p>
It is a subclass of <a class="link" href="GooCanvasItemModelSimple.html" title="GooCanvasItemModelSimple"><span class="type">GooCanvasItemModelSimple</span></a> and so inherits all of the
style properties such as "stroke-color", "fill-color" and "line-width".
</p>
<p>
It also implements the <a class="link" href="GooCanvasItemModel.html" title="GooCanvasItemModel"><span class="type">GooCanvasItemModel</span></a> interface, so you can use the
<a class="link" href="GooCanvasItemModel.html" title="GooCanvasItemModel"><span class="type">GooCanvasItemModel</span></a> functions such as <a class="link" href="GooCanvasItemModel.html#goo-canvas-item-model-raise" title="goo_canvas_item_model_raise ()"><code class="function">goo_canvas_item_model_raise()</code></a> and
<a class="link" href="GooCanvasItemModel.html#goo-canvas-item-model-rotate" title="goo_canvas_item_model_rotate ()"><code class="function">goo_canvas_item_model_rotate()</code></a>.
</p>
<p>
<a class="link" href="GooCanvasPathModel.html" title="GooCanvasPathModel"><span class="type">GooCanvasPathModel</span></a> uses the same path specification strings as the Scalable
Vector Graphics (SVG) path element. For details see the
<a class="ulink" href="http://www.w3.org/Graphics/SVG/" target="_top">SVG specification</a>.
</p>
<p>
To create a <a class="link" href="GooCanvasPathModel.html" title="GooCanvasPathModel"><span class="type">GooCanvasPathModel</span></a> use <a class="link" href="GooCanvasPathModel.html#goo-canvas-path-model-new" title="goo_canvas_path_model_new ()"><code class="function">goo_canvas_path_model_new()</code></a>.
</p>
<p>
To get or set the properties of an existing <a class="link" href="GooCanvasPathModel.html" title="GooCanvasPathModel"><span class="type">GooCanvasPathModel</span></a>, use
<code class="function">g_object_get()</code> and <code class="function">g_object_set()</code>.
</p>
<p>
To respond to events such as mouse clicks on the path you must connect
to the signal handlers of the corresponding <a class="link" href="GooCanvasPath.html" title="GooCanvasPath"><span class="type">GooCanvasPath</span></a> objects.
(See <a class="link" href="GooCanvas.html#goo-canvas-get-item" title="goo_canvas_get_item ()"><code class="function">goo_canvas_get_item()</code></a> and <a class="link" href="GooCanvas.html#GooCanvas-item-created" title='The "item-created" signal'><span class="type">"item-created"</span></a>.)
