Set inactive color for customized titlebar

Question

我遵循了uwp titlebar示例 ，除了一件事之外，它都可以正常工作，titlebar的颜色始终相同，但是当窗口不在前景中时，它应该有所不同，我尝试使用LayoutMetricsChanged和IsVisibleChanged收听散焦事件，但它不起作用，那么如何设置新栏的不同颜色并使之像真实的呢？

Check this article : Eternal Coding - Take the control of your titlebar .

You will have to handle the event Window.Current.Activated . For example, here is the code extracted from the same article:

private void Current_Activated(object sender, WindowActivatedEventArgs e)
{
    if (e.WindowActivationState != CoreWindowActivationState.Deactivated)
    {
        BackButtonGrid.Visibility = Visibility.Visible;
        MainTitleBar.Opacity = 1;
    }
    else
    {
        BackButtonGrid.Visibility = Visibility.Collapsed;
        MainTitleBar.Opacity = 0.5;
    }
}

This snippet will update the opacity of its custom title bar when the window gains or losts focus.
