<p>GooCanvasTextModel represents a model for text 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 "fill-color".</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>To create a <a class="link" href="GooCanvasTextModel.html" title="GooCanvasTextModel"><span class="type">GooCanvasTextModel</span></a> use <a class="link" href="GooCanvasTextModel.html#goo-canvas-text-model-new" title="goo_canvas_text_model_new ()"><code class="function">goo_canvas_text_model_new()</code></a>.</p>
<p>To get or set the properties of an existing <a class="link" href="GooCanvasTextModel.html" title="GooCanvasTextModel"><span class="type">GooCanvasTextModel</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 text item you must connect
to the signal handlers of the corresponding <a class="link" href="GooCanvasText.html" title="GooCanvasText"><span class="type">GooCanvasText</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>.)</p>
