<a name="id3130673"></a><h2>Description</h2>
<p>
GooCanvasWidget provides support for placing any GtkWidget in the canvas.
</p>
<p>
The <a class="link" href="GooCanvasWidget.html#GooCanvasWidget--width"><span class="type">"width"</span></a> and <a class="link" href="GooCanvasWidget.html#GooCanvasWidget--height"><span class="type">"height"</span></a> properties specify
the widget's size. If either of them is -1, then the requested size of the
widget is used instead, which is the default for both width and height.
</p>
<p>
Note that there are a number of limitations in the use of <span class="type">""</span>
</p>
<p>
</p>
<div class="itemizedlist"><ul type="disc">
<li><p>
It doesn't support any transformation besides simple translation.
This means you can't scale a canvas with a <a class="link" href="GooCanvasWidget.html" title="GooCanvasWidget"><span class="type">GooCanvasWidget</span></a> in it.
</p></li>
<li><p>
It doesn't support layering, so you can't place other items beneath
or above the <a class="link" href="GooCanvasWidget.html" title="GooCanvasWidget"><span class="type">GooCanvasWidget</span></a>.
</p></li>
<li><p>
It doesn't support rendering of widgets to a given cairo_t, which
means you can't output the widget to a pdf or postscript file.
</p></li>
<li><p>
It doesn't have a model/view variant like the other standard items,
so it can only be used in a simple canvas without a model.
</p></li>
<li><p>
It can't be made a static item.
</p></li>
