	// Create our main SFGUI window

	// Almost everything in SFGUI is handled through smart pointers
	// for automatic resource management purposes. You create them

	// For more things to set around the window refer to the
	// API documentation.

			// to enable user interactivity. Without doing this your
			// GUI is nothing but a big colorful picture ;)

		// Update the GUI, note that you shouldn't normally
		// pass 0 seconds to the update method.
		window->Update( 0.f );

		// Clear screen
		app_window.clear();

		// After drawing the rest of your game, you have to let the GUI
		// render itself. If you don't do this you will never be able
		// to see it ;)
		sfgui.Display( app_window );

		// NOTICE
		// Because the window doesn't have any children it will shrink to
		// it's minimum size of (0,0) resulting in you not seeing anything
		// except the title bar text ;) Don't worry, in the Label example
		// you'll get to see more.
