透明的 UWP 窗口 10 [英] Transparent UWP windows 10

问题描述

我想弄清楚如何在应用程序上设置透明背景，让用户看到背后.我尝试更改 xaml 文件中的 background 和 opacity 参数，但没有任何改变.

我也在背景中设置了透明图像

<ImageBrush Stretch="Fill" ImageSource="Assets/fond.png"/></Page.Background>

但它不起作用

有人知道如何执行此操作吗?

解决方案

tl;dr

也许这不是直接的透视"，但我认为这是您想要的.

我认为它在 SDK Preview 中可用，但我不确定，因为我没有尝试过.

更新:

我刚刚注意到在 Compositor 类中预发布了 CreateHostBackdropBrush() 函数.https://docs.microsoft.com/en-us/uwp/api/windows.ui.composition.compositor

更新:

在 Fall Creators Update 中，它甚至可以作为 XAML 代码使用，非常快速且易于编写.

I am trying to figure out how to have a transparent background on the app, that lets the user see behind it. I've tried to change background and opacity parameters in xaml file, but nothing changed.

I have set a transparent image in background also

<Page.Background>
    <ImageBrush Stretch="Fill" ImageSource="Assets/fond.png"/>
</Page.Background>

But it doesn't work

Does anyone know how to perform this?

You will be able to do it after the update of Windows 10 that is coming.

And the github: https://github.com/Microsoft/WindowsUIDevLabs/tree/master/SampleGallery/Samples/SDK%20Insider/BlurPlayground

Maybe it's not the straight "see through", but I think it's what you would like to have.

EDIT: I think it is available in the SDK Preview, but I'm not sure because I didn't try it.

UPDATE:

I've just noticed prelease of CreateHostBackdropBrush() function in Compositor class. https://docs.microsoft.com/en-us/uwp/api/windows.ui.composition.compositor

UPDATE:

In Fall Creators Update it's even available as XAML code that's very fast and easy to write.
