Nebula2探秘11-Simple Window

happykevins文

前面的10节主要讲的是Nebula2内核层模块的应用，所以一直在黑黑Dos控制台下工作，可能大家已经非常想念Windows窗口了:) 从本章起，我将开始介绍Nebula2的应用层模块，并以一个最简单的Windows窗口程序开始。虽然简单，但是我们可以从中了解到Nebula2启动一个Windows窗口所需要的依赖，并且也简单的勾画了一个Nebula2的游戏循环。

  代码如下：
<div style="padding-right: 5.4pt; padding-left: 5.4pt; background: #e6e6e6; padding-bottom: 4px; width: 95%; padding-top: 4px;">/****************************************************************************/
