The reason is that we need to be able to fade these real bits of UI in and out
as we transition from front to back, but we need to make sure the VisualBrush
in the 3D model doesn't also get faded out. So the VisualBrush uses the inner
Border, while the fade is applied to the outer one.

这只是窗体内容翻转，如何连同窗体一起翻转？？？ --------------------编程问答-------------------- --------------------编程问答-------------------- --------------------编程问答-------------------- 帮顶，我也不懂，楼主你的代码太多 ，没时间看啊 --------------------编程问答-------------------- 你大概看看，说个思路也行啊。谢谢！ --------------------编程问答-------------------- 依我看, QQ概念版 实际窗体并未翻转, 只是内容都在一个容器内, 如你的Viewport3D, 窗体设为无边框, 最大化最小化这些按钮都是自己画的
然后容器翻转的时候, 你看上去就是窗体在翻转, 其实不然 --------------------编程问答-------------------- WPF无边框窗体，Viewport3D中加载一个旋转的子控件，样子整成窗体的样子。不过不确定是否能透明，自己测试下 --------------------编程问答-------------------- VS里面不是有tabControl控件吗，这个能用不
补充：.NET技术 , C#
