Keterangan

Konstruktor

TappedRoutedEventArgs()

Menginisialisasi instans baru kelas TappedRoutedEventArgs .

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.
