Keterangan

Perhatikan bahwa pengaturan properti Durasi tidak berpengaruh pada objek ini karena durasi telah dikonfigurasi sebelumnya.

Konstruktor

SwipeBackThemeAnimation()

Menginisialisasi instans baru kelas SwipeBackThemeAnimation .

Properti

AutoReverse	Mendapatkan atau menetapkan nilai yang menunjukkan apakah garis waktu diputar secara terbalik setelah menyelesaikan perulangan ke depan. (Diperoleh dari Timeline)
BeginTime	Mendapatkan atau mengatur waktu di mana Garis Waktu ini harus dimulai. (Diperoleh dari Timeline)
Dispatcher	Mendapatkan CoreDispatcher yang dikaitkan dengan objek ini. CoreDispatcher mewakili fasilitas yang dapat mengakses DependencyObject pada utas UI meskipun kode dimulai oleh utas non-UI. (Diperoleh dari DependencyObject)
Duration	Mendapatkan atau mengatur lamanya waktu diputarnya garis waktu ini, tidak menghitung pengulangan. (Diperoleh dari Timeline)
FillBehavior	Mendapatkan atau menetapkan nilai yang menentukan bagaimana animasi berperilaku setelah mencapai akhir periode aktifnya. (Diperoleh dari Timeline)
FromHorizontalOffset	Mendapatkan atau mengatur jarak di mana target diterjemahkan ke arah horizontal saat animasi aktif.
FromHorizontalOffsetProperty	Mengidentifikasi properti dependensi FromHorizontalOffset .
FromVerticalOffset	Mendapatkan atau mengatur jarak di mana target diterjemahkan ke arah vertikal saat animasi aktif.
FromVerticalOffsetProperty	Mengidentifikasi properti dependensi FromHorizontalOffset .
RepeatBehavior	Mendapatkan atau mengatur perilaku berulang dari garis waktu ini. (Diperoleh dari Timeline)
SpeedRatio	Mendapatkan atau menetapkan tarif, relatif terhadap induknya, pada saat itu berlangsung untuk Garis Waktu ini. (Diperoleh dari Timeline)
TargetName	Mendapatkan atau mengatur nama referensi elemen kontrol yang ditargetkan.
TargetNameProperty	Mengidentifikasi properti dependensi TargetName .

Metode

ClearValue(DependencyProperty)	Menghapus nilai lokal properti dependensi. (Diperoleh dari DependencyObject)
GetAnimationBaseValue(DependencyProperty)	Mengembalikan nilai dasar apa pun yang ditetapkan untuk properti dependensi, yang akan berlaku dalam kasus di mana animasi tidak aktif. (Diperoleh dari DependencyObject)
GetValue(DependencyProperty)	Mengembalikan nilai efektif properti dependensi saat ini dari DependencyObject. (Diperoleh dari DependencyObject)
ReadLocalValue(DependencyProperty)	Mengembalikan nilai lokal properti dependensi, jika nilai lokal ditetapkan. (Diperoleh dari DependencyObject)
RegisterPropertyChangedCallback(DependencyProperty, DependencyPropertyChangedCallback)	Mendaftarkan fungsi pemberitahuan untuk mendengarkan perubahan pada DependencyProperty tertentu pada instans DependencyObject ini. (Diperoleh dari DependencyObject)
SetValue(DependencyProperty, Object)	Mengatur nilai lokal properti dependensi pada DependencyObject. (Diperoleh dari DependencyObject)
UnregisterPropertyChangedCallback(DependencyProperty, Int64)	Membatalkan pemberitahuan perubahan yang sebelumnya terdaftar dengan memanggil RegisterPropertyChangedCallback. (Diperoleh dari DependencyObject)

Acara

Completed

Terjadi ketika objek Storyboard telah selesai diputar. (Diperoleh dari Timeline)
