Public Property Strokes As StrokeCollection

Property Value

StrokeCollection

The collection of Stroke objects contained within the InkCanvas.

Examples

The following example demonstrates how to use two StrokeCollection objects for the same InkCanvas. In this example, player one and player two each use an individual "inking surface" even though they share the same InkCanvas. This example assumes the click event is connected to the event handler, 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

The following example demonstrates how to bind the Strokes property of an InkCanvas to another 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>
