represents a text item. It is a subclass of
<code class="classname">goocanvas.ItemSimple</code>
and so inherits all of the style properties such as "stroke-color", "fill-color" and "line-width".
It also implements the <code class="classname">goocanvas.Item</code>
interface, so you can use the <code class="classname">goocanvas.Item</code>
functions such as <code class="methodname">goocanvas.Item.raise_()</code>

Creates a new canvas text item.

Here's an example showing how to create a text item with the bottom
right of the text box placed at (500,500):
</p><pre class="programlisting">
text = goocanvas.Text(text="Hello, World!", x=500, y=500
width=200, anchor=gtk.ANCHOR_SE,
fill_color="blue")
</pre></div><div class="refsect1" title="Methods"><a name="idp1106768"></a><h2>Methods</h2><div class="refsect2" title="goocanvas.Text.get_natural_extents"><a name="method-goocanvastext--get-natural-extents"></a><h3>goocanvas.Text.get_natural_extents</h3><pre class="programlisting"><code class="methodsynopsis"> def <span class="methodname">get_natural_extents</span>(<span class="methodparam"></span>)</code></pre><table border="0" width="100%" bgcolor="#FFECCE"><col align="left" valign="top" width="0*"><tbody><tr><td><p><span class="term"><span class="emphasis"><em>Returns</em></span>:</span></p></td><td>a 2-tuple containing two 4-tuples representing the ink and
logical rectangles used to store the extents of glyph as drawn.</td></tr></tbody></table><p>
Gets the natural extents of the text, in the text item's coordinate space.
The final extents of the text may be different, if the text item is placed
in a layout container such as
<code class="classname">goocanvas.Table</code>.
