Keterangan

Peristiwa DoubleTapped dikirim setiap kali mouse diklik dua kali atau jari atau pena mengetuk objek dua kali berturut-turut dengan cepat.

Konstruktor

DoubleTappedRoutedEventArgs()

Menginisialisasi instans baru kelas DoubleTappedRoutedEventArgs .

Properti

Handled	Mendapatkan atau menetapkan nilai yang menandai peristiwa yang dirutekan sebagai ditangani. Nilai yang benar untuk Ditangani mencegah sebagian besar handler di sepanjang rute peristiwa menangani peristiwa yang sama lagi.
OriginalSource	Mendapatkan referensi ke objek yang memunculkan peristiwa. Ini sering merupakan bagian templat dari kontrol daripada elemen yang dideklarasikan di UI aplikasi Anda. (Diperoleh dari RoutedEventArgs)
PointerDeviceType	Mendapatkan PointerDeviceType untuk perangkat penunjuk yang memulai peristiwa input terkait.

Metode

GetPosition(UIElement)

Mengembalikan koordinat x- dan y dari posisi penunjuk, secara opsional dievaluasi terhadap asal koordinat UIElement yang disediakan.
