欢迎您对Quartz--v0.041（初步测试版）的测试！这个版本是Quartz--v0.04版本经过Dx8.1改进到Dx9.0c以后的第一个稳定版本，这次的修改涉及到了很多的底层部分重写，性能和易用性上都有了很大的提高，但是功能上还存在着很多的没有完善的地方以及缺陷，这些除了我已知的以外，在测试中遇到的问题，也希望大家能够提出来，我会根据需求分类尽快完善。
Quartz--的使用很简单，例题我也直接采用MS的SDK中的例题，这样就更方便了大家的调试，在Tutorial文件夹中我们用第一个例题CreateDevice来做。本例题要实现的目标是GUI系统基本设备的关联和鼠标的显示，这些东西即是最基本的也是最简单的。
首先拷贝这个例题到新的目录，然后编译确保可以通过（很重要，经常会有初学者本地代码编译不了，类似于这样的乌龙事件遇到过不少了）。然后将GUI.rar解压到Tut01_CreateDevice当前目录的GUI中。然后用下面的代码更换掉当前代码，然后我们在做具体的代码分析。

在以后的使用当中你会发现这些并非是必须要的，但是为了更好的让你的游戏与UI系统结合，建议使用这些初始化。这里的CUIWindowManagerRUN();函数表示这些设备开始运行，函数名称后来发现有些不妥当，会在以后的版本中更换。
