<div class="refsect1" lang="en">
<a name="id3133551"></a><h2>Description</h2>
<p>
GooCanvasEllipseModel represents a model for ellipse items.
</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="goocanvas-goocanvasitemmodel.html#GooCanvasItemModel"><span class="type">GooCanvasItemModel</span></a> interface, so you can use the
<a class="link" href="goocanvas-goocanvasitemmodel.html#GooCanvasItemModel"><span class="type">GooCanvasItemModel</span></a> functions such as <a class="link" href="goocanvas-goocanvasitemmodel.html#goo-canvas-item-model-raise"><code class="function">goo_canvas_item_model_raise()</code></a> and
<a class="link" href="goocanvas-goocanvasitemmodel.html#goo-canvas-item-model-rotate"><code class="function">goo_canvas_item_model_rotate()</code></a>.
</p>
<p>
To create a <a class="link" href="GooCanvasEllipseModel.html" title="GooCanvasEllipseModel"><span class="type">GooCanvasEllipseModel</span></a> use <a class="link" href="GooCanvasEllipseModel.html#goo-canvas-ellipse-model-new"><code class="function">goo_canvas_ellipse_model_new()</code></a>.
</p>
<p>
To get or set the properties of an existing <a class="link" href="GooCanvasEllipseModel.html" title="GooCanvasEllipseModel"><span class="type">GooCanvasEllipseModel</span></a>, use
<a
href="/usr/share/gtk-doc/html/gobject/gobject-The-Base-Object-Type.html#g-object-get"
><code class="function">g_object_get()</code></a> and <a
href="/usr/share/gtk-doc/html/gobject/gobject-The-Base-Object-Type.html#g-object-set"
><code class="function">g_object_set()</code></a>.
</p>
<p>
The ellipse can be specified either with the "center-x", "center-y",
"radius-x" and "radius-y" properties, or with the "x", "y", "width" and
"height" properties.
</p>
<p>
To respond to events such as mouse clicks on the ellipse you must connect
to the signal handlers of the corresponding <a class="link" href="GooCanvasEllipse.html" title="GooCanvasEllipse"><span class="type">GooCanvasEllipse</span></a> objects.
(See <a class="link" href="GooCanvas.html#goo-canvas-get-item"><code class="function">goo_canvas_get_item()</code></a> and <a class="link" href="GooCanvas.html#GooCanvas-item-created"><span class="type">"item-created"</span></a>.)</p>

Here's an example showing how to create an ellipse centered at (100.0,
100.0), with a horizontal radius of 50.0 and a vertical radius of 30.0.
It is drawn with a red outline with a width of 5.0 and filled with blue:
