範例

下列範例示範如何使用 GetLayoutSlot 並繪製 Rectangle 的周框方 塊。

<StackPanel x:Name="sp1" Grid.Row="0" Background="LightBlue"
            Height="100" Width="200"
            HorizontalAlignment="Left" VerticalAlignment="Top" >
    <Rectangle x:Name="rect1" Fill="Blue"  Width="100" Height="50" ></Rectangle>
</StackPanel>
<Button Content="Get Layout Slot" 
        Grid.Row="1" Width="150" Height="50" 
        Click="Button_Click" HorizontalAlignment="Left"/>

private void Button_Click(object sender, RoutedEventArgs e)
{
    //Get Layout Slot of Rectangle
    Windows.Foundation.Rect r1 = LayoutInformation.GetLayoutSlot(rect1);
    RectangleGeometry rg1 = new RectangleGeometry();
    rg1.Rect = r1;
    Path mypath = new Path();
    mypath.Data = rg1;
    mypath.Stroke = new SolidColorBrush(Colors.Red);
    mypath.StrokeThickness = 4;
    LayoutRoot.Children.Add(mypath);
}

Private Sub Button_Click(ByVal sender As Object, ByVal e As RoutedEventArgs)
    'Get Layout Slot of Rectangle 
    Dim r1 As Rect = LayoutInformation.GetLayoutSlot(rect1)
    Dim rg1 As New RectangleGeometry()
    rg1.Rect = r1
    Dim mypath As New Path()
    mypath.Data = rg1
    mypath.Stroke = New SolidColorBrush(Colors.Black)
    mypath.StrokeThickness = 4
    LayoutRoot.Children.Add(mypath)
End Sub
