Commenti
Un evento DoubleTapped viene inviato ogni volta che un mouse viene fatto doppio clic o un dito o una penna tocca l'oggetto due volte in successione rapida.
Costruttori
DoubleTappedRoutedEventArgs() |
Inizializza una nuova istanza della classe DoubleTappedRoutedEventArgs . |
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. |
