【CEGUI】 Window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 'root' 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.

This means that we can// specify sizes and positions without having to know the exact pixel size// of the elements in advance.

These are// specified using relative co-ordinates, but the important thing to note// is that these settings are aways relative to the display rather than the// parent window.//// here we set a maximum size for the FrameWindow which is equal to the size// of the display, and a minimum size of one tenth of the display.wnd->setMaxSize(USize(cegui_reldim(1.0f), cegui_reldim( 1.0f)));wnd->setMinSize(USize(cegui_reldim(0.1f), cegui_reldim( 0.1f)));// As a final step in the initialisation of our sample window, we set the window's// text to "Hello World!", so that this text will appear as the caption in the// FrameWindow's titlebar.wnd->setText("Hello World Linduo!");wnd->subscribeEvent(CEGUI::Window::EventMouseClick,  Event::Subscriber(&HelloWorldDemo::handleHelloWorldClicked, this));// return true so that the samples framework knows that initialisation was a// success, and that it should now run the sample.return true;
