Comentarios

ScrollViewer permite mostrar el contenido en un área menor que su tamaño real. Cuando el contenido de ScrollViewer no está completamente visible, ScrollViewer muestra barras de desplazamiento que el usuario puede usar para mover las áreas de contenido que están visibles. El área que incluye todo el contenido de ScrollViewer es la extensión. El área visible del contenido es la ventanilla.

Es raro declarar un elemento ScrollViewer como parte de la interfaz de usuario de la página de la aplicación. Es más habitual que un control ScrollViewer exista como componente de otros controles. Una parte de ScrollViewer junto con la clase ScrollContentPresenter para compatibilidad mostrará una ventanilla junto con las barras de desplazamiento solo cuando el espacio de diseño del control de host esté restringido a menos espacio que el tamaño de contenido expandido. Este suele ser el caso de las listas, así que las plantillas de ListView y GridView siempre incluyen ScrollViewer. TextBox y RichEditBox también incluyen un objeto ScrollViewer en las plantillas.

Cuando existe un elemento ScrollViewer en un control, el control host suele tener control de eventos integrado para determinados eventos de entrada y manipulaciones que permiten el desplazamiento del contenido. Por ejemplo, la clase GridView interpreta un gesto de deslizar rápidamente y esto hace que el contenido se desplace horizontalmente. Se considera que el control host es el encargado de controlar los eventos de entrada y las manipulaciones sin formato que recibe, y que los eventos de un nivel más bajo, como PointerPressed, tampoco se generarán ni se propagarán a ninguno de los contenedores primarios. Puede cambiar parte de la administración de controles integrada reemplazando una clase de control y los métodos virtuales On* para los eventos o volviendo a crear plantillas para el control. Pero en cualquier caso no es trivial reproducir el comportamiento predeterminado original, que suele hacer que el control reaccione de la forma esperada ante los eventos, las acciones de entrada del y los gestos. Po lo que debería considerar si realmente necesita que se desencadene ese evento. Quizá desee investigar si hay otros eventos o gestos de entrada que no se administren mediante controles y utilizarlos en el diseño de interacción de la aplicación o el control.

Para que sea posible para los controles que incluyen ScrollViewer influir en algunos comportamientos y propiedades que están dentro del elemento ScrollViewer, ScrollViewer define varias propiedades adjuntas XAML que se pueden establecer en estilos y utilizar en los enlaces de plantilla.

Propiedades adjuntas XAML ScrollViewer

ScrollViewer define las propiedades adjuntas XAML siguientes:

Las propiedades adjuntas XAML están pensadas para los casos donde la clase ScrollViewer es implícita, por ejemplo cuando ScrollViewer existe en la plantilla predeterminada de ListView o GridView, y desea poder influir en el comportamiento de desplazamiento del control sin tener acceso a partes de la plantilla. Para los casos en los que la clase ScrollViewer esté explícita en su código XAML, tal como se muestra en el código de ejemplo de la sección Ejemplos, no será necesario usar la sintaxis de la propiedad adjunta. Simplemente utilice la sintaxis de atributo, por ejemplo <ScrollViewer ZoomMode="Enabled" />.

Para admitir el acceso del procesador XAML a las propiedades adjuntas, y también para exponer las operaciones Get y Set equivalentes al código, cada propiedad adjunta XAML tiene un par de métodos de descriptor de acceso Get y Set. Por ejemplo, los métodos GetHorizontalScrollMode y SetHorizontalScrollMode admiten y proporcionan compatibilidad equivalente solo para código para ScrollViewer.HorizontalScrollMode. O bien, puede utilizar el sistema de propiedades de dependencia para obtener o establecer el valor de propiedad adjunta. Llame a GetValue o SetValue, pasando los argumentos del identificador de propiedad de dependencia para establecer, y una referencia al objeto de destino en el que se va a obtener o establecer el valor.

Comportamiento de Windows 8

Control de gestos mediante dispositivos de panel táctil

Para Windows 8, los gestos de dispositivo de panel táctil que se controlaron por entrada por una parte de control de ScrollViewer se interpretaron como entrada de rueda del mouse y así desencadenarían un evento PointerWheelChanged. A partir de Windows 8.1, ScrollViewer utiliza una lógica de manipulación subyacente que interpreta gestos de dispositivo de panel táctil como acciones a la que responde el objeto ScrollViewer, por lo que el gesto se considera administrado por el control y el evento PointerWheelChanged no se desencadena más.

Si migra el código de la aplicación de Window 8 a Windows 8.1, quizá desee tener en cuenta este cambio de comportamiento porque da lugar a que PointerWheelChanged se desencadene en menos casos. Además, el comportamiento que se integra ahora en ScrollViewer podría estar duplicando lo que haya hecho el controlador.

Las aplicaciones que se compilaron para Windows 8 pero se ejecutan en Windows 8.1 siguen usando el comportamiento de Windows 8.

Interfaz de usuario de la aplicación para el teclado en pantalla

Windows 8 tenía una lógica implementada internamente que asociaría un ScrollViewer a la interfaz de usuario global de la aplicación siempre que el usuario invocara el teclado en pantalla. Este teclado en pantalla es una característica de accesibilidad específica que los usuarios solicitan a través del Centro de accesibilidad. No es igual que el teclado de software que pueden aparecer en la interfaz de usuario de la aplicación para los controles de entrada de texto, si el sistema no detecta ningún dispositivo de teclado. Lo que el ScrollViewer interno hace aquí es permitir el desplazamiento del área donde está la aplicación, si el desplazamiento está forzado porque el teclado está ocupando espacio de la interfaz de usuario.

A partir de Windows 8.1, el sistema todavía tiene comportamiento de UI/diseño cuando aparece el teclado en pantalla, pero ya no usa este objeto ScrollViewer creado internamente. En su lugar se utiliza un control interno dedicado que el código de la aplicación no puede cambiar ni inspeccionar.

La mayoría de los aspectos de este cambio de comportamiento no afectan a las aplicaciones en absoluto. Sin embargo, puede que la aplicación haya anticipado este comportamiento, proporcionando un Style implícito para ScrollViewer concebido para cambiar el diseño, o bien, recorriendo el árbol con VisualTreeHelper para encontrar este ScrollViewer creado internamente y modificarlo en tiempo de ejecución. El código no será útil para aplicaciones compiladas para Windows 8.1.

Las aplicaciones que se compilaron para Windows 8 pero se ejecutan en Windows 8.1 siguen usando el comportamiento de Windows 8.

Ejemplos

El código XAML siguiente crea un objeto TextBlock grande dentro de un control ScrollViewer, junto con otra copia de TextBlock para fines de comparación.


  <StackPanel>
      <!-- A large TextBlock. -->
      <TextBlock Width="300" TextWrapping="Wrap" Margin="0,0,0,30" 
        Text="Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed ac mi ipsum. Phasellus vel malesuada mauris. Donec pharetra, enim sit amet mattis tincidunt, felis nisi semper lectus, vel porta diam nisi in augue. Pellentesque lacus tortor, aliquam et faucibus id, rhoncus ut justo. Sed id lectus odio, eget pulvinar diam. Suspendisse eleifend ornare libero, in luctus purus aliquet non. Sed interdum, sem vitae rutrum rhoncus, felis ligula ultrices sem, in eleifend eros ante id neque." />
      
      <!-- The same large TextBlock, wrapped in a ScrollViewer. -->
      <ScrollViewer Height="200" Width="200" 
                    HorizontalScrollBarVisibility="Auto" 
                    VerticalScrollBarVisibility="Auto">
          <TextBlock Width="300" TextWrapping="Wrap"
              Text="Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed ac mi ipsum. Phasellus vel malesuada mauris. Donec pharetra, enim sit amet mattis tincidunt, felis nisi semper lectus, vel porta diam nisi in augue. Pellentesque lacus tortor, aliquam et faucibus id, rhoncus ut justo. Sed id lectus odio, eget pulvinar diam. Suspendisse eleifend ornare libero, in luctus purus aliquet non. Sed interdum, sem vitae rutrum rhoncus, felis ligula ultrices sem, in eleifend eros ante id neque." />
      </ScrollViewer>
  </StackPanel>
