WPF自定义控件（三）——Window

　　一样！先来看看效果吧：

　　

　　怎么样？效果很好吧，而且不只是样式哟！所有系统窗体有的交互操作都可以实现！

　　但可惜。。。有很多和系统API有关的东西本人了解得并不多，所以这个窗体是基于他人的成果上产生的。关于窗体交互的东西还是看看原作者的吧：

　　接下来说说我在这上面多加的功能：可设置标题栏可见性，可扩展标题栏下拉按钮，可全屏并拦截键盘，另外还多公布了一些属性

　　再来一张图：

　　

　　这就是没有标题栏的，只是设置一个属性就可以了哟！

　　废话不多说了！再来看看我代码，只发一些我加了的吧，上面的链接里有的我就不发了，想看完整的，之后我会发源码的。
