Esempio

I frammenti di codice seguenti provengono dallo scenario 1 - Eventidi input dell'esempio di input di base.

Scenario1::Scenario1()
{
    InitializeComponent();

    // pointer press/release handlers
    pressedTarget.PointerPressed(this, &Scenario1::target_PointerPressed);

    // pointer enter/exit handlers
    enterExitTarget.PointerEntered(this, &Scenario1::target_PointerEntered);

Commenti

Un evento Tapped viene inviato ogni volta che un mouse viene fatto clic o un dito o una penna tocca l'oggetto

Costruttori

TappedRoutedEventArgs()

Inizializza una nuova istanza della classe TappedRoutedEventArgs .

Proprietà

Handled

Ottiene o imposta un valore che contrassegna l'evento indirizzato come gestito. Un valore true per Handled impedisce la maggior parte dei gestori lungo la route dell'evento di gestire di nuovo lo stesso evento.
OriginalSource

Ottiene un riferimento all'oggetto che ha generato l'evento. Questa è spesso una parte del modello di un controllo anziché un elemento dichiarato nell'interfaccia utente dell'app.

(Ereditato da RoutedEventArgs)
PointerDeviceType

Ottiene pointerDeviceType per il dispositivo puntatore che ha avviato l'evento di input associato.

Metodi

GetPosition(UIElement)

Restituisce le coordinate x e y della posizione del puntatore, facoltativamente valutate in base a un'origine coordinata di un UIElement fornito.
