The <code class="classname">Pango::Layout</code> object for printing should be created by calling the <code class="methodname">PrintContext::create_pango_layout()</code> method. The <code class="classname">PrintContext</code> object also provides the page metrics, via <code class="methodname">get_width()</code> and <code class="methodname">get_height()</code>. The number of pages can be set with <code class="methodname">PrintOperation::set_n_pages()</code>. To actually render the Pango text in <code class="literal">on_draw_page</code>, get a <code class="classname">Cairo::Context</code> with <code class="methodname">PrintContext::get_cairo_context()</code> and show the <code class="classname">Pango::LayoutLine</code>s that appear within the requested page number. </p> <p> See <a class="link" href="sec-printing-example.html#sec-printing-example-simple" title="Simple">an example</a> of exactly how this can be done. </p> </div> <div class="navfooter"> <hr> <table width="100%" summary="Navigation footer"> <tr> <td width="40%" align="left"> <a accesskey="p" href="sec-page-setup.html"><img src="icons/prev.png" alt="Prev"></a> </td> <td width="20%" align="center"><a accesskey="u" href="chapter-printing.html"><img src="icons/up.png" alt="Up"></a></td> <td width="40%" align="right"> <a accesskey="n" href="sec-async-printing-ops.html"><img src="icons/next.png" alt="Next"></a> </td> </tr> <tr> <td width="40%" align="left" valign="top">Page setup </td> <td width="20%" align="center"><a accesskey="h" href="index.html"><img src="icons/home.png" alt="Home"></a></td> <td width="40%" align="right" valign="top"> Asynchronous operations</td> </tr> </table> </div> </body> </html>
