<p>
<a class="link" href="GooCanvasGroupModel.html" title="GooCanvasGroupModel"><span class="type">GooCanvasGroupModel</span></a> represents a group of items. Groups can be nested to
any depth, to create a hierarchy of items. Items are ordered within each
group, with later items being displayed above earlier items.
</p>
<p>
<a class="link" href="GooCanvasGroupModel.html" title="GooCanvasGroupModel"><span class="type">GooCanvasGroupModel</span></a> 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". Setting a style property on a <a class="link" href="GooCanvasGroupModel.html" title="GooCanvasGroupModel"><span class="type">GooCanvasGroupModel</span></a> will
affect all children of the <a class="link" href="GooCanvasGroupModel.html" title="GooCanvasGroupModel"><span class="type">GooCanvasGroupModel</span></a> (unless the children
override the property setting).
</p>
<p>
<a class="link" href="GooCanvasGroupModel.html" title="GooCanvasGroupModel"><span class="type">GooCanvasGroupModel</span></a> 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>, and the
properties such as "visibility" and "pointer-events".
</p>
<p>
To create a <a class="link" href="GooCanvasGroupModel.html" title="GooCanvasGroupModel"><span class="type">GooCanvasGroupModel</span></a> use <a class="link" href="GooCanvasGroupModel.html#goo-canvas-group-model-new" title="goo_canvas_group_model_new ()"><code class="function">goo_canvas_group_model_new()</code></a>.
</p>
<p>
To get or set the properties of an existing <a class="link" href="GooCanvasGroupModel.html" title="GooCanvasGroupModel"><span class="type">GooCanvasGroupModel</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 group you must connect
to the signal handlers of the corresponding <a class="link" href="GooCanvasGroup.html" title="GooCanvasGroup"><span class="type">GooCanvasGroup</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>.)
