Definición

Espacio de nombres:
System.Windows.Media.Animation
Ensamblado:
PresentationFramework.dll

Busca este objeto Storyboard en una nueva posición cuando tiene lugar el siguiente paso del reloj.

Sobrecargas

Seek(TimeSpan)

Busca este Storyboard hasta la posición especificada. El Storyboard realiza la búsqueda solicitada cuando se produce el siguiente ciclo de reloj.
Seek(TimeSpan, TimeSeekOrigin)

Busca este Storyboard hasta la posición especificada. El Storyboard realiza la búsqueda solicitada cuando se produce el siguiente ciclo de reloj.
Seek(FrameworkContentElement, TimeSpan, TimeSeekOrigin)

Busca este Storyboard hasta la posición especificada. El Storyboard realiza la búsqueda solicitada cuando se produce el siguiente ciclo de reloj.
Seek(FrameworkElement, TimeSpan, TimeSeekOrigin)

Busca este Storyboard hasta la posición especificada. El Storyboard realiza la búsqueda solicitada cuando se produce el siguiente ciclo de reloj.

Seek(TimeSpan)

Busca este Storyboard hasta la posición especificada. El Storyboard realiza la búsqueda solicitada cuando se produce el siguiente ciclo de reloj.

public:
 void Seek(TimeSpan offset);
public void Seek (TimeSpan offset);
member this.Seek : TimeSpan -> unit
Public Sub Seek (offset As TimeSpan)

Parámetros

offset
TimeSpan

Valor positivo o negativo que describe cuánto debe avanzar o retroceder la escala de tiempo.

Comentarios

Tenga en cuenta que las operaciones de búsqueda no tienen en cuenta la configuración o SlipBehavior del SpeedRatio guión gráfico. El guión gráfico se trata como si tiene un SpeedRatio de 1 y ningún SlipBehavior.

Para controlar interactivamente este guión gráfico, debe usar el mismo containingObject parámetro al llamar a los métodos interactivos que usó para comenzar el guión gráfico. Un guión gráfico controlable puede pausar, reanudar, buscar, detener y quitarse. Para que un guión gráfico sea controlable en el código, debe usar la sobrecarga adecuada del método del Begin guión gráfico y especificar true para que sea controlable. Para obtener un ejemplo, vea Cómo: Controlar un guión gráfico después de que se inicie.

Se aplica a

Seek(TimeSpan, TimeSeekOrigin)

Busca este Storyboard hasta la posición especificada. El Storyboard realiza la búsqueda solicitada cuando se produce el siguiente ciclo de reloj.

public:
 void Seek(TimeSpan offset, System::Windows::Media::Animation::TimeSeekOrigin origin);
public void Seek (TimeSpan offset, System.Windows.Media.Animation.TimeSeekOrigin origin);
member this.Seek : TimeSpan * System.Windows.Media.Animation.TimeSeekOrigin -> unit
Public Sub Seek (offset As TimeSpan, origin As TimeSeekOrigin)

Parámetros

offset
TimeSpan

Valor positivo o negativo que describe cuánto debe avanzar o retroceder la escala de tiempo desde el origin especificado.

origin
TimeSeekOrigin

Posición desde la que se aplica offset.

Se aplica a

Seek(FrameworkContentElement, TimeSpan, TimeSeekOrigin)

Busca este Storyboard hasta la posición especificada. El Storyboard realiza la búsqueda solicitada cuando se produce el siguiente ciclo de reloj.

public:
 void Seek(System::Windows::FrameworkContentElement ^ containingObject, TimeSpan offset, System::Windows::Media::Animation::TimeSeekOrigin origin);
public void Seek (System.Windows.FrameworkContentElement containingObject, TimeSpan offset, System.Windows.Media.Animation.TimeSeekOrigin origin);
member this.Seek : System.Windows.FrameworkContentElement * TimeSpan * System.Windows.Media.Animation.TimeSeekOrigin -> unit
Public Sub Seek (containingObject As FrameworkContentElement, offset As TimeSpan, origin As TimeSeekOrigin)

Parámetros

containingObject
FrameworkContentElement

Objeto especificado cuando se llamó al método Begin(FrameworkContentElement, Boolean). Este objeto contiene los objetos Clock que se crearon para este guion gráfico y sus elementos secundarios.

offset
TimeSpan

Valor positivo o negativo que describe cuánto debe avanzar o retroceder la escala de tiempo desde el origin especificado.

origin
TimeSeekOrigin

Posición desde la que se aplica offset.

Tenga en cuenta que las operaciones de búsqueda no tienen en cuenta la configuración o SlipBehavior del SpeedRatio guión gráfico. El guión gráfico se trata como si tiene un SpeedRatio de 1 y ningún SlipBehavior.

Este método cambia el reloj del CurrentState guión gráfico a Active. Este método no tiene ningún efecto en el árbol de tiempo hasta la próxima vez que se procese un tic. Como efecto secundario, los eventos adecuados tampoco se generan hasta entonces.

Para controlar interactivamente este guión gráfico, debe usar el mismo containingObject parámetro al llamar a los métodos interactivos que usó para comenzar el guión gráfico. Un guión gráfico controlable puede pausar, reanudar, buscar, detener y quitarse. Para que un guión gráfico sea controlable en el código, debe usar la sobrecarga adecuada del método del Begin guión gráfico y especificar true para que sea controlable. Para obtener un ejemplo, vea Cómo: Controlar un guión gráfico después de que se inicie.

La búsqueda de un guión gráfico desencadena los CurrentGlobalSpeedInvalidated eventos y CurrentStateInvalidated .

Se aplica a

Seek(FrameworkElement, TimeSpan, TimeSeekOrigin)

Busca este Storyboard hasta la posición especificada. El Storyboard realiza la búsqueda solicitada cuando se produce el siguiente ciclo de reloj.

public:
 void Seek(System::Windows::FrameworkElement ^ containingObject, TimeSpan offset, System::Windows::Media::Animation::TimeSeekOrigin origin);
public void Seek (System.Windows.FrameworkElement containingObject, TimeSpan offset, System.Windows.Media.Animation.TimeSeekOrigin origin);
member this.Seek : System.Windows.FrameworkElement * TimeSpan * System.Windows.Media.Animation.TimeSeekOrigin -> unit
Public Sub Seek (containingObject As FrameworkElement, offset As TimeSpan, origin As TimeSeekOrigin)

Parámetros

containingObject
FrameworkElement

Objeto especificado cuando se llamó al método Begin(FrameworkElement, Boolean). Este objeto contiene los objetos Clock que se crearon para este guion gráfico y sus elementos secundarios.

offset
TimeSpan

Valor positivo o negativo que describe cuánto debe avanzar o retroceder la escala de tiempo desde el origin especificado.

origin
TimeSeekOrigin

Posición desde la que se aplica offset.

Ejemplos

En el ejemplo siguiente se muestra cómo buscar (omitir) a un segundo después de comenzar un Guión gráfico.

Tenga en cuenta que las operaciones de búsqueda no tienen en cuenta la configuración o SlipBehavior del SpeedRatio guión gráfico. El guión gráfico se trata como si tiene un SpeedRatio de 1 y ningún SlipBehavior.

Este método cambia el reloj del CurrentState guión gráfico a Active. Este método no tiene ningún efecto en el árbol de tiempo hasta la próxima vez que se procese un tic. Como efecto secundario, los eventos adecuados tampoco se generan hasta entonces.

Para controlar interactivamente este guión gráfico, debe usar el mismo containingObject parámetro al llamar a los métodos interactivos que usó para comenzar el guión gráfico. Un guión gráfico controlable puede pausar, reanudar, buscar, detener y quitarse si se hace controlable. Para que un guión gráfico sea controlable en el código, debe usar la sobrecarga adecuada del método del Begin guión gráfico y especificar true para que sea controlable. Para obtener un ejemplo, vea Cómo: Controlar un guión gráfico después de que se inicie.

La búsqueda de un guión gráfico desencadena los CurrentGlobalSpeedInvalidated eventos y CurrentStateInvalidated .
