Penggunaan lanjutan

Penghapusan

Setiap kali properti dari tampilan berubah, peristiwa tampilan Invalidated dinaikkan. Ini bermanfaat untuk mengetahui kapan harus membuat ulang tampilan.

Interaksi

Interaksi dasar tersedia melalui kontrol Tap yang meningkatkan peristiwa ketika pengguna menyentuh bingkainya. Ini adalah tampilan seperti komponen lainnya.

 this . Button = new Tap ( )
{
    BackgroundBrush = new ColorBrush ( SKColors . DeepPink ) ,
    CornerRadius = 5 ,
} ;

this . Button . Tapped += ( s , e ) => Debug . WriteLine ( "Tapped" ) ;
this . Button . Pressed += ( s , e ) => ( ( Tap ) s ) . BackgroundBrush = new ColorBrush ( SKColors . LightPink ) ;
this . Button . Released += ( s , e ) => ( ( Tap ) s ) . BackgroundBrush = new ColorBrush ( SKColors . DeepPink ) ;
