Comentários

Um evento Holding é enviado sempre que um dedo, uma caneta ou um dispositivo de apontamento semelhante é pressionado e mantido em um objeto .

Depois que um limite de tempo curto tiver decorrido, o evento será enviado com um HoldingState do tipo Iniciado.

Quando o dispositivo é levantado (após um evento Holding ), outro evento Holding é enviado com um HoldingState do tipo Concluído.

Se o usuário cancelar a retenção depois de ser iniciada, mas antes de ser concluída, um evento Holding será enviado com um HoldingState do tipo Cancelado.

Construtores

HoldingRoutedEventArgs()

Inicializa uma nova instância da classe HoldingRoutedEventArgs .

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.

HoldingState

Obtém o HoldingState subjacente para a interação

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.
