Remarques

Un événement Tapped est envoyé chaque fois qu’une souris est cliquée ou qu’un doigt ou un stylet appuie sur l’objet

Constructeurs

TappedRoutedEventArgs()

Initialise une nouvelle instance de la classe TappedRoutedEventArgs.

Propriétés

Handled

Obtient ou définit une valeur qui marque l’événement routé comme géré. Une valeur true pour Handled empêche la plupart des gestionnaires le long de l’itinéraire de l’événement de gérer à nouveau le même événement.

OriginalSource

Obtient une référence à l’objet qui a déclenché l’événement. Il s’agit souvent d’une partie de modèle d’un contrôle plutôt que d’un élément qui a été déclaré dans l’interface utilisateur de votre application.

(Hérité de RoutedEventArgs)
PointerDeviceType

Obtient le PointerDeviceType pour l’appareil pointeur qui a lancé l’événement d’entrée associé.

Méthodes

GetPosition(UIElement)

Retourne les coordonnées x et y de la position du pointeur, éventuellement évaluées par rapport à l’origine des coordonnées d’un élément UIElement fourni.
