Esempio
Nell'esempio seguente viene illustrato come usare due StrokeCollection oggetti che si trovano nello stesso InkCanvasoggetto . In questo esempio, giocatore uno e giocatore due usano una singola "superficie di input penna" anche se condividono lo stesso InkCanvas. In questo esempio si presuppone che l'evento switchPlayersButton_Click
sia connesso al gestore eventi.
StrokeCollection player1;
StrokeCollection player2;
void InitializePlayersCanvases()
{
player1 = inkCanvas1.Strokes;
player2 = new StrokeCollection();
}
// Use a different "inking surface" for each player.
void switchPlayersButton_Click(object sender, RoutedEventArgs e)
{
if (StrokeCollection.ReferenceEquals(inkCanvas1.Strokes, player1))
{
inkCanvas1.Strokes = player2;
}
else
{
inkCanvas1.Strokes = player1;
}
}
void inkCanvas1_StrokesReplaced(object sender, InkCanvasStrokesReplacedEventArgs e)
{
if (StrokeCollection.ReferenceEquals(e.NewStrokes, player1))
{
Title = "Player one's turn";
}
else
{
Title = "Player two's turn";
}
}
Private player1 As StrokeCollection
Private player2 As StrokeCollection
Sub InitializePlayersCanvases()
player1 = inkCanvas1.Strokes
player2 = New StrokeCollection()
End Sub
' Use a different "inking surface" for each player.
Private Sub switchPlayersButton_Click(ByVal sender As Object, ByVal e As RoutedEventArgs)
If StrokeCollection.ReferenceEquals(inkCanvas1.Strokes, player1) Then
inkCanvas1.Strokes = player2
Else
inkCanvas1.Strokes = player1
End If
End Sub
Private Sub inkCanvas1_StrokesReplaced(ByVal sender As Object, _
ByVal e As InkCanvasStrokesReplacedEventArgs)
