CEGUIWindow环境编译

CEGUI编译

• 平台：Window
• CEGUI版本：0.8.7
• 前提：Visual Studio任意版本（本文为2013）

CEGUI源码下载

登录CEGUI官网网站：
http://cegui.org.uk/download
下载CEGUI0.8.7源码+ 0.8.X Dependencies

• 下载完成后，解压（例：这里我解压到了D:/Myproject/Coding/CEGUI）
• 
• cegui-0.8.7是cegui的源码。cegui-dependencies-0.8.x 是cegui 0.8.x版本所需要的编译运行依赖环境。

编译cegui-dependicies-0.8.x

• 使用CMake编译起来非常方便，由于之后要编译为Visual Studio 2013可用项目。所以需要前安装 vs 2013。当然安装其他任意版本的vs也可以。
• 打开CMake，讲source和build目录设置为，cegui-dependicies-0.8.x目录。然后点击 “Configure”，在弹出的对话框选择“visual studio 2013对应的版本”，再次点击 configure。
  
• 点击“Generate”
  
• 点击open project，使用vs 2013打开项目 ，然后“生成解决方案”（release版）。然后将cegui-dependencies-0.8.x目录下的“dependecies”拷贝到“D:\Myproject\Coding\CEGUI\cegui-0.8.7”目录下面。

编译CEGUI

• 该步骤，与编译cegui-dependicies-0.8.x一致。使用CMake将，Source和Build设置为“D:\Myproject\Coding\CEGUI\cegui-0.8.7”。然后使用 VS2013打开，生成解决项目。
• 将dependecies目录设置为Path环境变量（例："D:\Myproject\Coding\CEGUI\cegui-0.8.7\dependencies\bin"目录）。
• 重启或注销电脑。

使用CEGUI自带SampleFramework

• CEGUI写了一套Sample框架，用一套框架运行多个SampleDemo。
• 将“CEGUISampleFramework-0.8”设置为启动项目，编译然后运行，如下图。
  
• 由于CEGUI提供了，SampleFrameWork，要花一定时间分析单个Demo是如何启动的。下面分析完成后，参考sampleFrameWork写的一段，可以运行的Demo.

This scheme also// loads in a font that gets used as the system default.SchemeManager::getSingleton().createFromFile("TaharezLook.scheme");// The next thing we do is to set a default mouse cursor image. This is// not strictly essential, although it is nice to always have a visible// cursor if a window or widget does not explicitly set one of its own.//// The TaharezLook Imageset contains an Image named "MouseArrow" which is// the ideal thing to have as a defult mouse cursor image.guiContext->getMouseCursor().setDefaultImage("TaharezLook/MouseArrow");// Now the system is initialised, we can actually create some UI elements, for// this first example, a full-screen &＃39;root&＃39; window is set as the active GUI// sheet, and then a simple frame window will be created and attached to it.// All windows and widgets are created via the WindowManager singleton.WindowManager& winMgr = WindowManager::getSingleton();// Here we create a "DefaultWindow". This is a native type, that is, it does// not have to be loaded via a scheme, it is always available. One common use// for the DefaultWindow is as a generic container for other windows. Its// size defaults to 1.0f x 1.0f using the Relative metrics mode, which means// when it is set as the root GUI sheet window, it will cover the entire display.// The DefaultWindow does not perform any rendering of its own, so is invisible.//// Create a DefaultWindow called &＃39;Root&＃39;.d_root = (DefaultWindow*)winMgr.createWindow("DefaultWindow", "Root");// load font and setup default if not loaded via schemeFont& defaultFont = FontManager::getSingleton().createFromFile("DejaVuSans-12.font");// Set default font for the gui contextguiContext->setDefaultFont(&defaultFont);// Set the root window as root of our GUI ContextguiContext->setRootWindow(d_root);// A FrameWindow is a window with a frame and a titlebar which may be moved around// and resized.//// Create a FrameWindow in the TaharezLook style, and name it &＃39;Demo Window&＃39;FrameWindow* wnd = (FrameWindow*)winMgr.createWindow("TaharezLook/FrameWindow", "Demo Window");// Here we attach the newly created FrameWindow to the previously created// DefaultWindow which we will be using as the root of the displayed gui.d_root->addChild(wnd);// Windows are in Relative metrics mode by default.
