Public Custom Event Completed As EventHandler 

例

次の例では、 Storyboard 2 つのオブジェクトを使用して、 Imageオブジェクトを使用してImageSource格納され、コントロールを使用して表示される2つのイメージ間のアニメーション遷移を作成します。In the following example, two Storyboard objects are used to create an animation transition between two images, stored using ImageSource objects and displayed using an Image control. 1つのストーリーボードでは、イメージコントロールが消えるまで縮小されます。One storyboard shrinks the image control until it disappears. 完了後は、古いImageSourceがもう一方ImageSourceのとスワップされ、もう1つのストーリーボードがフルサイズになるまでイメージコントロールを展開します。After it completes, the old ImageSource is swapped with the other ImageSource, and a second storyboard that expands the image control until it is full-sized again.

<!-- TimelineCompletedExample.xaml 
     This example creates an animated transition between
     two images. When the user clicks the Start Transition button,
     a storyboard shrinks an image until it disappears. 
     The Completed event is used to notify the class when this
     storyboard has completed. The code behind file handles
     this event by swapping the image and making it visible again.

注釈

このタイムラインがタイムラインツリーのルートタイムラインの場合は、アクティブな期間の最後 (繰り返しを含む) に到達し、すべての子がアクティブな期間の終わりに達した後に再生が完了しています。If this timeline is the root timeline of a timeline tree, it has completed playing after it reaches the end of its active period (which includes repeats) and all its children have reached the end of their active periods. このタイムラインが子タイムラインの場合は、所属するタイムラインツリーのルートタイムラインがアクティブな期間の終わりに達し、すべての子タイムラインが再生を終了したときに、完全に再生が完了したと見なされます。If this timeline is a child timeline, it is considered to have completely finished playing when the root timeline of the timeline tree to which it belongs reaches the end of its active period and all its child timelines have finished playing.

タイムラインを停止しても完了イベントはトリガーされませんが、塗りつぶし期間にスキップされます。Stopping a timeline does not trigger its completed event, but skipping it to its fill period does.

イベントハンドラーのパラメーターは、タイムラインのClockです。 Object EventHandlerThe Object parameter of the EventHandler event handler is the timeline's Clock.

このイベントハンドラーはタイムラインに関連付けられているように見えますClockが、実際には、このタイムライン用に作成されたに登録されます。Although this event handler appears to be associated with a timeline, it actually registers with the Clock created for this timeline. 詳細については、「タイミングイベントの概要」を参照してください。For more information, see the Timing Events Overview.
