Örnekler

Aşağıdaki örnekte, aynı InkCanvasüzerinde kalem ve vurgulayıcı kullanma deneyiminin benzetimini yapmak için iki DrawingAttributes nesnenin nasıl kullanılacağı gösterilmektedir. Örnekte, işaretleme dili (XAML) dosyasındaki kök öğesinin adlı rootolduğu DockPanel varsayılır. Ayrıca bir Button çağrı switchHighlighter olduğunu ve Click olayın olay işleyicisine bağlı olduğunu varsayar.

InkCanvas inkCanvas1 = new InkCanvas();

DrawingAttributes highlighterDA;
bool useHighlighter = false;

// Add an InkCanvas to the window, and allow the user to 
// switch between using a green pen and a purple highlighter 
// on the InkCanvas.

// Create a button called switchHighlighter and use 
// SwitchHighlighter_Click to handle the Click event.

Aşağıdaki örnekte özelliğin DefaultDrawingAttributes bir veri kaynağına nasıl bağlanacağınız gösterilmektedir.

<Canvas.Resources>
  <!--Define an array containing some DrawingAttributes.-->
  <x:Array x:Key="MyDrawingAttributes" x:Type="{x:Type DrawingAttributes}">
    <DrawingAttributes Color="Black" FitToCurve="true" Width="3" Height="3"/>
    <DrawingAttributes Color="Blue"  FitToCurve="false" Width="5" Height="5"/>
    <DrawingAttributes Color="Red"   FitToCurve="true" Width="7" Height="7"/>
  </x:Array>

  <!--Create a DataTemplate to display the DrawingAttributes shown above-->
  <DataTemplate DataType="{x:Type DrawingAttributes}" >
    <Border Width="80" Height="{Binding Path=Height}">
      <Border.Background >
        <SolidColorBrush Color="{Binding Path=Color}"/>
      </Border.Background>
    </Border>
  </DataTemplate>
</Canvas.Resources>

<!--Bind the InkCavas' DefaultDrawingAtributes to
    a Listbox, called lbDrawingAttributes.-->
<InkCanvas Name="inkCanvas1" Background="LightGreen" 
           Canvas.Top="400" Canvas.Left="0"

           DefaultDrawingAttributes="{Binding 
                ElementName=lbDrawingAttributes, Path=SelectedItem}"
           >
</InkCanvas>

<!--Use the array, MyDrawingAttributes, to populate a ListBox-->
<ListBox Name="lbDrawingAttributes" 
         Canvas.Top="400" Canvas.Left="450" 
         Height="100" Width="100"
