ここではコードのみを示し、原理についてはCEGUIの公式サイトのチュートリアルを参照してください.この映画はCEGUI公式サイトのチュートリアルに対応します:
  • The Beginner Guide to Getting CEGUI Rendering - How to initialise CEGUI to render properly.
  • The Beginner Guide to Resource Groups - How to define resource group locations and specify default resource groups.
  • The Beginner Guide to Loading Data Files and Initialisation - How to load some data files and perform basic system initialisation.
  • The Beginner Guide to Creating a CEGUI Window - How to create a simple window and get it on screen.

    これは、作成したウィンドウがまだ対応していないため、イベント処理関数の追加を開始します.
