VisualBrush.AutoLayoutContent Eigenschaft

Definition

Namespace:

System.Windows.Media

Assembly:

PresentationCore.dll

Ruft einen Wert ab, der angibt, ob dieser VisualBrush das Layout für das eigene Visual ausführt, oder legt diesen fest.

C#

public bool AutoLayoutContent { get; set; }

Eigenschaftswert

Boolean

true, wenn dieser Pinsel das Layout für das eigene Visual ausführen soll, andernfalls false. Der Standardwert ist true.

Beispiele

Das folgende Beispiel zeigt die Auswirkungen der AutoLayoutContent Eigenschaft auf ein nicht übergeordnetes UIElementElement.

C#

StackPanel myStackPanel = new StackPanel();
myStackPanel.Margin = new Thickness(20, 0, 0, 0);
TextBlock myTextBlock = new TextBlock();
myTextBlock.Margin = new Thickness(0, 10, 0, 0);
myTextBlock.Text = "AutoLayoutContent: True";
myStackPanel.Children.Add(myTextBlock);

Rectangle myRectangle = new Rectangle();
myRectangle.Width = 100;
myRectangle.Height = 100;
myRectangle.Stroke = Brushes.Black;
myRectangle.StrokeThickness = 1;

// Create the Fill for the rectangle using a VisualBrush.
VisualBrush myVisualBrush = new VisualBrush();
myVisualBrush.AutoLayoutContent = true;

// This button is used as the visual for the VisualBrush.
Button myButton = new Button();
myButton.Content = "Hello, World";

myVisualBrush.Visual = myButton;

// Set the fill of the Rectangle to the Visual Brush.
myRectangle.Fill = myVisualBrush;

myStackPanel.Children.Add(myRectangle);

TextBlock myTextBlock2 = new TextBlock();
myTextBlock2.Margin = new Thickness(0, 10, 0, 0);
myTextBlock2.Text = "AutoLayoutContent: False";
myStackPanel.Children.Add(myTextBlock2);

Rectangle myRectangle2 = new Rectangle();
myRectangle2.Width = 100;
myRectangle2.Height = 100;
myRectangle2.Stroke = Brushes.Black;
myRectangle2.StrokeThickness = 1;

// Create the Fill for the rectangle using a VisualBrush.
VisualBrush myVisualBrush2 = new VisualBrush();
myVisualBrush2.AutoLayoutContent = false;

// This button is used as the visual for the VisualBrush.
Button myButton2 = new Button();
myButton2.Content = "Hello, World";
myButton2.Width = 100;
myButton2.Height = 100;

myVisualBrush2.Visual = myButton2;

// Set the fill of the Rectangle to the Visual Brush.
myRectangle2.Fill = myVisualBrush2;

myStackPanel.Children.Add(myRectangle2);

XAML

  <TextBlock Margin="0,10,0,0">AutoLayoutContent: True</TextBlock>
  <Rectangle 
    Width="100"
