wpf - 如何在 WPF 中创建 Windows 8 风格的应用栏？

Question

我打算创建一个 Windows 8 风格的应用程序(Metro)，但发现不支持使用双屏，这是我的应用程序的需求。

现在我正在将我的应用程序重新设计为 WPF 中的桌面应用程序。
但我仍然喜欢从 Windows 8 应用程序中模仿一些不错的设计功能。

设计功能之一是 Windows 8 风格应用程序中通常使用的飞出栏:

命令的底部应用栏

顶部导航栏

适用于所有应用程序的正确魅力

它们的共同设计是一个临时弹出面板，它位于当前窗口布局的顶部。

我的问题是:如何在 WPF 中创建类似的东西？

我可以毫无问题地创建一个带有隐藏底行的主网格，该主网格可以显示一些常见的命令按钮。但是让它飞到我的标准布局之上会很好，而不是挤压它。

我知道可以在当前窗口之上打开一个新窗口，但这会造成糟糕的代码设计并且很难看起来漂亮。我宁愿在同一个窗口中进行。

很酷的问题!我最近实际上已经完成了魅力酒吧..

理想情况下，您需要的是类似

<Grid x:Name="LayoutRoot">

 <Grid x:Name="Overlay" Panel.ZIndex="1000" Visibility="Collapsed">
    <!-- This is where your slide out control is going to go -->
  </Grid>

  <!-- Use whatever layout you need -->
  <ContentControl x:Name="MainContent" />

</Grid>

现在不是挤压内容 - 覆盖网格将位于其顶部，类似于魅力栏!全部使用 XAML

如果您对此还有疑问，请给我留言!

我发现的一个小技巧是在未展开时将不透明度设置为 0，但将宽度设置为 10，这样用户就可以将鼠标放在屏幕的一侧，然后它会在大约一秒钟后出现。 .
干杯。
