It seems Apple's overlay is more than just a transparency. Any ideas on how to achieve this effect with WPF?

推荐答案

这是一个新窗口，窗口的一半（顶部）给出了少量的透明度。



您可以尝试添加一个黑色背景的新StackPanel，其Alpha值设置为.4到当前窗口，并填充底部80％与孩子一起将具有包含内容的Solid背景，其余的顶级内容将具有透明主题，因为StackPanel将具有透明度。



内容可以在底部使用

It is a new window coming up, and half the window (the top of it) is given a small amount of transparency to.

You can try to add a new StackPanel with Black background whose Alpha value is set to .4 to your current window, and fill the bottom 80% with a child that would have a Solid background with the content on it, the remaining top content would have a Transparent theme because the StackPanel would have the transparency.

The content can be aligned at the bottom using

<stackpanel name="newWindow">
   <!-- Following is the child panel with the Content; Background is White -->
   <stackpanel verticalalignment="Bottom" background="White">
      <!-- Add the content here -->
   </stackpanel>
</stackpanel>

您将在应用程序中显示或隐藏 newWindow 。
