Comentarios
Se envía un evento Holding cada vez que se presiona un dedo, un lápiz o un dispositivo señalador similar en un objeto.
Una vez transcurrido un umbral de tiempo corto, el evento se envía con un HoldingState de tipo Started.
Cuando se ha quitado el dispositivo (después de un evento Holding), se envía otro evento Holding con un HoldingState de tipo Completed.
Si el usuario cancela la suspensión después de que se haya iniciado, pero antes de que finalice, se envía un evento Holding con un HoldingState de tipo Canceled.
Constructores
HoldingRoutedEventArgs() |
Inicializa una nueva instancia de la clase HoldingRoutedEventArgs . |
Propiedades
Handled |
Obtiene o establece un valor que marca el evento enrutado como controlado. Un valor true para Handled impide que la mayoría de los controladores a lo largo de la ruta de eventos controlen de nuevo el mismo evento. |
HoldingState |
Obtiene el HoldingState subyacente para la interacción. |
OriginalSource |
Obtiene una referencia al objeto que generó el evento. Suele ser una parte de plantilla de un control en lugar de un elemento que se declaró en la interfaz de usuario de la aplicación. (Heredado de RoutedEventArgs) |
PointerDeviceType |
Obtiene pointerDeviceType para el dispositivo de puntero que inició el evento de entrada asociado. |
Métodos
GetPosition(UIElement) |
Devuelve las coordenadas x e y de la posición del puntero, que opcionalmente se evalúan con respecto a un origen de coordenadas de un UIElement proporcionado. |
