ContentThemeTransition 类
定义
重要
一些信息与预发行产品相关,相应产品在发行之前可能会进行重大修改。 对于此处提供的信息,Microsoft 不作任何明示或暗示的担保。
为控件的内容发生更改的情况提供动画过渡表现方式。 除了 AddDeleteThemeTransition 之外,可能还会应用此内容。

示例
以下示例将 ContentThemeAnimation 应用于矩形。
<!-- The ContentThemeTransition will execute when the ContentControl’s content changes. -->
<ContentControl x:Name="ContentHost" PointerPressed="ContentHost_PointerPressed">
<ContentControl.ContentTransitions>
<TransitionCollection>
<ContentThemeTransition/>
</TransitionCollection>
</ContentControl.ContentTransitions>
<Rectangle Height="200" Width="200" Fill="Orange"/>
</ContentControl>
private void ContentHost_PointerPressed(object sender, PointerRoutedEventArgs e)
{
// Replace the ContentControl's content with a new Rectangle of a random color.
Rectangle newItem = new Rectangle();
Random rand = new Random();
newItem.Height = 200;
newItem.Width = 200;
newItem.Fill = new SolidColorBrush(Color.FromArgb(255,
(byte)rand.Next(0, 255), (byte)rand.Next(0,255), (byte)rand.Next(0, 255)));
ContentHost.Content = newItem;
}
void ContentHost_PointerPressed(Windows::Foundation::IInspectable const& /* sender */,
Windows::UI::Xaml::Input::PointerRoutedEventArgs const& /* e */)
{
// Replace the ContentControl's content with a new Rectangle of a random color.
Windows::UI::Xaml::Shapes::Rectangle newItem;
newItem.Height(200);
newItem.Width(200);
Windows::UI::Color color;
color.R = std::rand() % 256;
color.G = std::rand() % 256;
color.B = std::rand() % 256;
newItem.Fill(Windows::UI::Xaml::Media::SolidColorBrush{ color });
ContentHost().Content(newItem);
}
void MyPage::ContentHost_PointerPressed(Object^ sender, PointerRoutedEventArgs^ e)
{
// Replace the ContentControl's content with a new Rectangle of a random color.
Rectangle^ newItem = ref new Rectangle();
newItem->Height = 200;
newItem->Width = 200;
Color color;
color.R = rand() % 256;
color.G = rand() % 256;
color.B = rand() % 256;
newItem->Fill = ref new SolidColorBrush(color);
ContentHost->Content = newItem;
}
注解
请注意,设置 Duration 属性不会影响此对象,因为持续时间是预配置的。
构造函数
ContentThemeTransition() |
初始化 ContentThemeTransition 类的新实例。 |
属性
Dispatcher |
获取与此 对象关联的 CoreDispatcher 。 CoreDispatcher 表示可以访问 UI 线程上的 DependencyObject 的工具,即使代码是由非 UI 线程启动的。 (继承自 DependencyObject) |
HorizontalOffset |
获取或设置转换处于活动状态时目标在水平方向上平移的距离。 |
HorizontalOffsetProperty |
标识 HorizontalOffset 依赖属性。 |
VerticalOffset |
获取或设置转换处于活动状态时目标在垂直方向上平移的距离。 |
VerticalOffsetProperty |
标识 VerticalOffset 依赖属性。 |
方法
ClearValue(DependencyProperty) |
清除依赖属性的本地值。 (继承自 DependencyObject) |
GetAnimationBaseValue(DependencyProperty) |
返回为依赖属性建立的任何基值,该基值适用于动画未处于活动状态的情况。 (继承自 DependencyObject) |
GetValue(DependencyProperty) |
从 DependencyObject 返回依赖属性的当前有效值。 (继承自 DependencyObject) |
ReadLocalValue(DependencyProperty) |
如果设置了本地值,则返回依赖属性的本地值。 (继承自 DependencyObject) |
RegisterPropertyChangedCallback(DependencyProperty, DependencyPropertyChangedCallback) |
注册一个通知函数,用于侦听此 DependencyObject 实例上特定 DependencyProperty 的更改。 (继承自 DependencyObject) |
SetValue(DependencyProperty, Object) |
设置 DependencyObject 上依赖属性的本地值。 (继承自 DependencyObject) |
UnregisterPropertyChangedCallback(DependencyProperty, Int64) |
取消以前通过调用 RegisterPropertyChangedCallback 注册的更改通知。 (继承自 DependencyObject) |
