範例

以下是一個使用PointerDown/Up主題動畫的自訂控制範本範例。

// Themes/Generic.xaml

     animations. The PointerDownThemeAnimation will be run when the control
     is in the PointerDown state.-->

備註

設定 持續時間 屬性對此物件沒有影響，因為持續時間是預先設定好的。

PointerDownThemeAnimation 覆蓋了目前投影（ Projection ）和 渲染轉換（RenderTransform）的數值。

Windows 8.1 及更早版本的投影與渲染轉換不受 PointerDownThemeAnimation 影響。
