问题描述
我只需要对自定义形状的 WPF 窗口的一部分应用 Aero 背景模糊.问题是要使用 DWM 应用模糊,我需要为 DwmEnableBlurBehindWindow
函数提供一个窗口句柄.
I need to apply an Aero background blur to only part of a custom-shaped WPF window. The problem is that to apply the blur with DWM, I need to provide a window handle to the DwmEnableBlurBehindWindow
function.
有人告诉我 WPF 弹出控件实际上是一个单独的窗口.那很好.我可以得到一个弹出窗口的句柄来对其应用模糊吗?如果是这样,如何?
I have been told that the WPF popup control is actually a separate window. That is good. Can I get a popup's handle to apply blur to it? If so, how?
推荐答案
试试这个
HwndSource source = (HwndSource)HwndSource.FromVisual(myPopup)
或者这个,但这个只适用于实际的 Windows,但可能有助于将来的参考.
or this but this one only works for actual Windows, but might help for future references.
IntPtr handle = new WindowInteropHelper(myWindow).Handle;
