Public Sub SeekAlignedToLastTick (containingObject As FrameworkContentElement, offset As TimeSpan, origin As TimeSeekOrigin)
Parametry
- containingObject
- FrameworkContentElement
Obiekt określony podczas wywoływanej Begin(FrameworkContentElement, Boolean) metody. Ten obiekt zawiera Clock obiekty utworzone dla tego scenorysu i jego elementów podrzędnych.
- offset
- TimeSpan
Wartość dodatnia lub ujemna, która opisuje ilość, według której oś czasu powinna przejść do przodu lub do tyłu z określonej wartości origin
.
- origin
- TimeSeekOrigin
Pozycja, z której offset
jest stosowana.

Uwagi
SeekAlignedToLastTick wyrównuje szukany czas ostatniego Storyboard znacznika zegara. Wartości są natychmiast aktualizowane, aby odzwierciedlić zmiany spowodowane przez SeekAlignedToLastTickprogram , mimo że ekran nie odzwierciedla tych zmian do momentu aktualizacji ekranu.
Należy pamiętać, że operacje wyszukiwania nie uwzględniają ustawień ani SlipBehavior scenorysuSpeedRatio. Scenorys jest traktowany tak, jakby miał SpeedRatio wartość 1 i nie SlipBehavior.
Ta metoda zmienia zegar scenorysu CurrentState na
Wyszukiwanie scenorysu CurrentGlobalSpeedInvalidated wyzwala zdarzenia i CurrentStateInvalidated .
Aby interaktywnie kontrolować ten scenorys, należy użyć tego samego containingObject
parametru podczas wywoływania interaktywnych metod użytych do rozpoczęcia scenorysu. Scenorys z możliwością sterowania może wstrzymywać, wznawiać, wyszukiwać, zatrzymywać i usuwać. Aby umożliwić sterowanie scenorysem w kodzie, należy użyć odpowiedniego przeciążenia metody scenorysu Begin i określić true
, aby można było go kontrolować. Aby zapoznać się z przykładem, zobacz How to: Control a Storyboard After It Starts (Instrukcje: kontrolowanie scenorysu po uruchomieniu).
Dotyczy

Uwagi
SeekAlignedToLastTick wyrównuje szukany czas ostatniego Storyboard znacznika zegara. Wartości są natychmiast aktualizowane, aby odzwierciedlić zmiany spowodowane przez SeekAlignedToLastTickprogram , mimo że ekran nie odzwierciedla tych zmian do momentu aktualizacji ekranu.
Należy pamiętać, że operacje wyszukiwania nie uwzględniają ustawień ani SlipBehavior scenorysuSpeedRatio. Scenorys jest traktowany tak, jakby miał SpeedRatio wartość 1 i nie SlipBehavior.
Ta metoda zmienia zegar scenorysu CurrentState na
Wyszukiwanie scenorysu CurrentGlobalSpeedInvalidated wyzwala zdarzenia i CurrentStateInvalidated .
Aby interaktywnie kontrolować ten scenorys, należy użyć tego samego containingObject
parametru podczas wywoływania interaktywnych metod użytych do rozpoczęcia scenorysu. Scenorys z możliwością sterowania może wstrzymywać, wznawiać, wyszukiwać, zatrzymywać i usuwać. Aby umożliwić sterowanie scenorysem w kodzie, należy użyć odpowiedniego przeciążenia metody scenorysu Begin i określić true
, aby można było go kontrolować. Aby zapoznać się z przykładem, zobacz How to: Control a Storyboard After It Starts (Instrukcje: kontrolowanie scenorysu po uruchomieniu).
