L'insieme degli oggetti Stroke contenuti in InkCanvas.

Esempio

Nell'esempio seguente viene illustrato come usare due StrokeCollection oggetti per lo 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 click sia connesso al gestore eventi, switchPlayersButton_Click.

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)

    If StrokeCollection.ReferenceEquals(e.NewStrokes, player1) Then
        Title = "Player one's turn"
    Else
        Title = "Player two's turn"
    End If

End Sub

Nell'esempio seguente viene illustrato come associare la Strokes proprietà di un oggetto InkCanvas a un altro InkCanvas.

<InkCanvas Background="LightGray" 
           Canvas.Top="0" Canvas.Left="0" 
           Height="400" Width="200" Name="ic"/>

<!-- Bind the Strokes of the second InkCavas to the first InkCanvas
     and mirror the strokes along the Y axis.-->
<InkCanvas Background="LightBlue"  
           Canvas.Top="0" Canvas.Left="200" 
           Height="400" Width="200" 
           Strokes="{Binding ElementName=ic, Path=Strokes}">
  <InkCanvas.LayoutTransform>
    <ScaleTransform ScaleX="-1" ScaleY="1" />
  </InkCanvas.LayoutTransform>
</InkCanvas>
