Keterangan

Peristiwa DoubleTapped dikirim setiap kali mouse diklik ganda 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 true untuk Handled mencegah sebagian besar handler di sepanjang rute peristiwa menangani peristiwa yang sama lagi.
OriginalSource

Mendapatkan referensi ke objek yang menaikkan peristiwa. Ini sering menjadi bagian templat dari kontrol daripada elemen yang dideklarasikan di antarmuka pengguna 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.
