Animatable.BeginAnimation Yöntem

Tanım

Belirtilen DependencyPropertyöğesine bir animasyon uygular.

Aşırı Yüklemeler

BeginAnimation(DependencyProperty, AnimationTimeline)

Belirtilen DependencyPropertyöğesine bir animasyon uygular. Animasyon, bir sonraki kare işlendiğinde başlatılır. Belirtilen özellik zaten animasyonluysa, SnapshotAndReplace iletim davranışı kullanılır.

BeginAnimation(DependencyProperty, AnimationTimeline, HandoffBehavior)

Belirtilen DependencyPropertyöğesine bir animasyon uygular. Animasyon, bir sonraki kare işlendiğinde başlatılır. Belirtilen özellik zaten animasyonluysa, belirtilen HandoffBehavior kullanılır.

Örnekler

Aşağıdaki örnekte, farklı HandoffBehavior ayarları kullanarak animasyonların nasıl uygulanacağı gösterilmektedir.

/*

This sample animates the position of an ellipse when 
the user clicks within the main border. If the user
left-clicks, the SnapshotAndReplace HandoffBehavior
is used when applying the animations. If the user
right-clicks, the Compose HandoffBehavior is used
instead.
