Glib::RefPtr<PrintOperation> op = PrintOperation::create(); // ...set up op... op->run(Gtk::PRINT_OPERATION_ACTION_PREVIEW, *this); </pre> <p> </p> <p> On Unix, the default preview handler uses an external viewer program. On Windows, the native preview dialog will be shown. If necessary you may override this behaviour and provide a custom preview dialog. See the example located in /examples/book/printing/advanced. </p> </div> <div class="navfooter"> <hr> <table width="100%" summary="Navigation footer"> <tr> <td width="40%" align="left"> <a accesskey="p" href="ch18s06.html"><img src="../icons/prev.png" alt="Prev"></a> </td> <td width="20%" align="center"><a accesskey="u" href="ch18.html"><img src="../icons/up.png" alt="Up"></a></td> <td width="40%" align="right"> <a accesskey="n" href="ch18s08.html"><img src="../icons/next.png" alt="Next"></a> </td> </tr> <tr> <td width="40%" align="left" valign="top">Extending the print dialog </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"> Example</td> </tr> </table> </div> </body> </html>
