是否可以获取WPF Popup控件的Hwnd? [英] Is it possible to get the Hwnd of a WPF Popup control?

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.问题是要对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.我可以获取弹出窗口的句柄以对其应用模糊处理吗?如果是这样，怎么办?

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

尝试一下

HwndSource source = (HwndSource)HwndSource.FromVisual(myPopup)

或此，但此仅适用于实际的Windows，但可能对将来的参考有所帮助.

or this but this one only works for actual Windows, but might help for future references.

IntPtr handle = new WindowInteropHelper(myWindow).Handle;
