Areo Glass Effect和windowStyle设置为none会导致窗口调整大小无法正常工作
Areo Glass Effect和windowStyle设置为none,AllowTransparency导致寡妇调整大小无法正常工作
将Areo Glass主题添加到我的窗口并将WindowState设置为None后,窗口不会正确调整大小.我可以按照我想要的那样大,但是当缩小尺寸时,玻璃效果会保持相同的宽度和高度.
例如,我单击最大化.窗口扩展到全屏大小.但是当恢复我的窗户恢复而不是玻璃效果.
我真正想要的只是模糊效果.我不关心玻璃,但这似乎是我可以获得透明模糊的唯一方法.
我怎样才能解决这个问题？

看来这AllowsTransparency == True就是这种行为的根源。因此您可以将其删除。但是，您应该将背景画笔的不透明度设置为零：
<Window.Background>
<SolidColorBrush Opacity="0" Color="Transparent"/>
</Window.Background>
这与设置CompositionTarget.BackgroundColor为透明一起，并且使用DwmEnableBlurBehindWindow函数将产生与设置类似的结果AllowsTransparency == True。
然而，通过这些修改，窗口的外观由于其边框而不太令人愉快。如果你设置了，边框就会消失ResizeMode=="NoResize"。但是，在这种情况下，您应该自行调整大小。幸运的是，通过添加 Thumb 并处理 DragDelta 事件，这很容易。这是完整的代码：
