+/** Example 009 Mesh Viewer

+

+This tutorial show how to create a more complex application with the engine.

+We construct a simple mesh viewer using the user interface API and the

+scene management of Irrlicht. The tutorial show how to create and use Buttons,

+Windows, Toolbars, Menus, ComboBoxes, Tabcontrols, Editboxes, Images,

+MessageBoxes, SkyBoxes, and how to parse XML files with the integrated XML

+reader of the engine.

+

+We start like in most other tutorials: Include all necessary header files, add

+a comment to let the engine be linked with the right .lib file in Visual

+Studio, and declare some global variables. We also add two 'using namespace'

+statements, so we do not need to write the whole names of all classes. In this

+tutorial, we use a lot stuff from the gui namespace.

+ <p>This tutorial show how to create a more complex application with the engine. We construct a simple mesh viewer using the user interface API and the scene management of Irrlicht. The tutorial show how to create and use Buttons, Windows, Toolbars, Menus, ComboBoxes, Tabcontrols, Editboxes, Images, MessageBoxes, SkyBoxes, and how to parse XML files with the integrated XML reader of the engine.</p>
+<p>We start like in most other tutorials: Include all necessary header files, add a comment to let the engine be linked with the right .lib file in Visual Studio, and declare some global variables. We also add two 'using namespace' statements, so we do not need to write the whole names of all classes. In this tutorial, we use a lot stuff from the gui namespace. </p><div class="fragment"><div class="line"><span class="preprocessor">#include &lt;irrlicht.h&gt;</span></div><div class="line"><span
