c# - 禁用 WPF 窗口焦点

Question

我有一个 WPF 窗口，只有当您通过 Visibility.Hidden 和 Visibility.Visible 按住 Tab 键时才会显示。但是，按住该键会将焦点从事件应用程序转移到 WPF 窗口。我可以禁用此行为吗？更进一步:是否可以完全阻止窗口在单击控件时获得焦点，但仍会注册控件的单击操作？

在别处找到答案:

protected override void OnSourceInitialized(EventArgs e)
{
    base.OnSourceInitialized(e);

    //Set the window style to noactivate.
    var helper = new WindowInteropHelper(this);
    SetWindowLong(helper.Handle, GWL_EXSTYLE,
        GetWindowLong(helper.Handle, GWL_EXSTYLE) | WS_EX_NOACTIVATE);
}   

private const int GWL_EXSTYLE = -20;
private const int WS_EX_NOACTIVATE = 0x08000000;

[DllImport("user32.dll")]
public static extern IntPtr SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong);

[DllImport("user32.dll")]
public static extern int GetWindowLong(IntPtr hWnd, int nIndex);
