Comentários

Um evento Tapped é enviado sempre que um mouse é clicado ou um dedo ou caneta toca no objeto

Construtores

TappedRoutedEventArgs()

Inicializa uma nova instância da classe TappedRoutedEventArgs .

Propriedades

Handled

Obtém ou define um valor que marca o evento roteado como manipulado. Um valor verdadeiro para Handled impede que a maioria dos manipuladores ao longo da rota de evento manipule o mesmo evento novamente.

OriginalSource

Obtém uma referência ao objeto que gerou o evento. Isso geralmente é uma parte de modelo de um controle em vez de um elemento que foi declarado na interface do usuário do aplicativo.

(Herdado de RoutedEventArgs)
PointerDeviceType

Obtém o PointerDeviceType para o dispositivo de ponteiro que iniciou o evento de entrada associado.

Métodos

GetPosition(UIElement)

Retorna as coordenadas x e y da posição do ponteiro, opcionalmente avaliadas em relação a uma origem de coordenada de um UIElement fornecido.
