核心代码：

HWND hWnd = HWND(winId());
	HMODULE hUser = GetModuleHandle(L"user32.dll");
	if (hUser)
	{
		pfnSetWindowCompositionAttribute setWindowCompositionAttribute = (pfnSetWindowCompositionAttribute)GetProcAddress(hUser, "SetWindowCompositionAttribute");
		if (setWindowCompositionAttribute)
		{
			ACCENT_POLICY accent = { ACCENT_ENABLE_BLURBEHIND, 0, 0, 0 };
			WINDOWCOMPOSITIONATTRIBDATA data;
			data.Attrib = WCA_ACCENT_POLICY;
			data.pvData = &accent;
			data.cbData = sizeof(accent);
			setWindowCompositionAttribute(hWnd, &data);
		}
	}
