在Windows 8.1中,我正在使用新的SettingsFlyout控件。弹出窗口正确设置动画,如果您使用控件的内置后退按钮返回“设置超级按钮”弹出按钮,则会生成动画。但是如果你通过在弹出窗口外面点击来点亮它,它就会在没有过渡动画的情况下消失。
当你点亮SettingsFlyout时,如何为转换设置动画? (我不想返回设置魅力弹出窗口,我只是希望它在光线消失时滑出。)

Matt,您想要做的事情应该很容易实现,但目前XAML SettingsFlyout API不支持开箱即用。正如Jerry指出的那样,有些过渡允许动画效果(在XAML中你想要EdgeUIThemeTransition)。遗憾的是,在SettingsFlyout上没有API支持来添加此转换,但您可以使用自己的私有弹出窗口来托管SettingsFlyout(详见下文):
public sealed partial class SettingsFlyout1 : SettingsFlyout
{
Popup _p;
Border _b;
public SettingsFlyout1()
{
this.InitializeComponent();
BackClick += SettingsFlyout1_BackClick;
Unloaded += SettingsFlyout1_Unloaded;
Tapped += SettingsFlyout1_Tapped;
}
void SettingsFlyout1_BackClick(object sender, BackClickEventArgs e)
{
_b.Child = null;
SettingsPane.Show();
}
void SettingsFlyout1_Unloaded(object sender, RoutedEventArgs e)
{
if (_p != null)
{
_p.IsOpen = false;
}
}
void SettingsFlyout1_Tapped(object sender, TappedRoutedEventArgs e)
{
e.Handled = true;
}
public void ShowCustom()
{
_p = new Popup();
_b = new Border();
_b.ChildTransitions = new TransitionCollection();
// TODO: if you support right-to-left builds, make sure to test all combinations of RTL operating
// system build (charms on left) and RTL flow direction for XAML app. EdgeTransitionLocation.Left
// may need to be used for RTL (and HorizontalAlignment.Left on the SettingsFlyout below).
_b.ChildTransitions.Add(new EdgeUIThemeTransition() { Edge = EdgeTransitionLocation.Right });
_b.Background = new SolidColorBrush(Colors.Transparent);
_b.Width = Window.Current.Bounds.Width;
_b.Height = Window.Current.Bounds.Height;
_b.Tapped += b_Tapped;
this.HorizontalAlignment = HorizontalAlignment.Right;
_b.Child = this;
_p.Child = _b;
_p.IsOpen = true;
}
void b_Tapped(object sender, TappedRoutedEventArgs e)
{
Border b = (Border)sender;
b.Child = null;
}
}

我认为SettingsFlyout应该为您的方案提供API支持,因此我在XAML团队中提交了一个工作项。将来,这些请求/问题也可以在MSDN论坛上提出(由MSFT人员主持)。这里的限制是在Popup上使用IsLightDismissEnabled =“True”实现了SettingsFlyout,而light-dismiss事件当前立即关闭Popup而不允许卸载子转换运行。我认为这可以克服,并且可以在SettingsFlyout API级别支持转换以启用您的方案。

您需要使用HideEdgeUI动画
