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. |
