(There is no actual <a class="link" href="GooCanvasItemModel.html" title="GooCanvasItemModel"><span class="type">GooCanvasItemModel</span></a> struct, since it is only an interface.

Simple item models only need to implement the <code class="function">get_parent()</code>, <code class="function">set_parent()</code>

Items that support transforms should also implement <code class="function">get_transform()</code> and

Container items must implement <code class="function">get_n_children()</code> and <code class="function">get_child()</code>.
Containers that support dynamic changes to their children should implement

Layout containers like <a class="link" href="GooCanvasTable.html" title="GooCanvasTable"><span class="type">GooCanvasTable</span></a> may implement
