Beispiele

Im folgenden Beispiel wird veranschaulicht, wie die Orientation Eigenschaft in Extensible Application Markup Language (XAML) festgelegt wird.

<Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" WindowTitle="WrapPanel Properties Sample">
  <Border HorizontalAlignment="Left" VerticalAlignment="Top" BorderBrush="Black" BorderThickness="2">
        <WrapPanel Orientation="Horizontal" Background="Azure" ItemWidth="25" ItemHeight="25" Height="200" Width="200">
            <Button Width="200">Button 1</Button>
            <Button>Button 2</Button>
            <Button>Button 3</Button>
        </WrapPanel>
  </Border>    
</Page>

Im folgenden Beispiel wird veranschaulicht, wie die Orientation Eigenschaft mithilfe von Code festgelegt wird.

// Create the application's main window
mainWindow = gcnew System::Windows::Window();
mainWindow->Title = "WrapPanel Sample";


// Instantiate a new WrapPanel and set properties
myWrapPanel = gcnew WrapPanel();
myWrapPanel->Background = Brushes::Azure;
myWrapPanel->Orientation = Orientation::Horizontal;
myWrapPanel->ItemHeight = 25;

myWrapPanel->ItemWidth = 75;
myWrapPanel->Width = 150;
myWrapPanel->HorizontalAlignment = HorizontalAlignment::Left;
myWrapPanel->VerticalAlignment = VerticalAlignment::Top;

// Define 3 button elements. Each button is sized at width of 75, so the third button wraps to the next line.
btn1 = gcnew Button();
btn1->Content = "Button 1";
btn2 = gcnew Button();
btn2->Content = "Button 2";
btn3 = gcnew Button();
btn3->Content = "Button 3";

// Add the buttons to the parent WrapPanel using the Children.Add method.
myWrapPanel->Children->Add(btn1);
myWrapPanel->Children->Add(btn2);
myWrapPanel->Children->Add(btn3);

// Add the WrapPanel to the MainWindow as Content
mainWindow->Content = myWrapPanel;
mainWindow->Show();

// Create the application's main window
mainWindow = new System.Windows.Window();
mainWindow.Title = "WrapPanel Sample";


// Instantiate a new WrapPanel and set properties
myWrapPanel = new WrapPanel();
myWrapPanel.Background = System.Windows.Media.Brushes.Azure;
myWrapPanel.Orientation = Orientation.Horizontal;
myWrapPanel.Width = 200;
myWrapPanel.HorizontalAlignment = HorizontalAlignment.Left;
myWrapPanel.VerticalAlignment = VerticalAlignment.Top;

// Define 3 button elements. The last three buttons are sized at width 
// of 75, so the forth button wraps to the next line.
btn1 = new Button();
btn1.Content = "Button 1";
btn1.Width = 200;
btn2 = new Button();
btn2.Content = "Button 2";
btn2.Width = 75;
btn3 = new Button();
btn3.Content = "Button 3";
btn3.Width = 75;
btn4 = new Button();
btn4.Content = "Button 4";
btn4.Width = 75;

// Add the buttons to the parent WrapPanel using the Children.Add method.
myWrapPanel.Children.Add(btn1);
myWrapPanel.Children.Add(btn2);
myWrapPanel.Children.Add(btn3);
myWrapPanel.Children.Add(btn4);

// Add the WrapPanel to the MainWindow as Content
mainWindow.Content = myWrapPanel;
mainWindow.Show();

WindowTitle = "WrapPanel Sample"

' Instantiate a new WrapPanel and set properties
Dim myWrapPanel As New WrapPanel()
myWrapPanel.Background = Brushes.Azure
myWrapPanel.Orientation = Orientation.Horizontal

myWrapPanel.Width = 200
myWrapPanel.HorizontalAlignment = Windows.HorizontalAlignment.Left
myWrapPanel.VerticalAlignment = Windows.VerticalAlignment.Top

' Define 3 button elements. The last three buttons are sized at width 
' of 75, so the forth button wraps to the next line.
Dim btn1 As New Button()
btn1.Content = "Button 1"
btn1.Width = 200
Dim btn2 As New Button()
btn2.Content = "Button 2"
btn2.Width = 75
Dim btn3 As New Button()
btn3.Content = "Button 3"
btn3.Width = 75
Dim btn4 As New Button()
btn4.Content = "Button 4"
btn4.Width = 75

' Add the buttons to the parent WrapPanel using the Children.Add method.
myWrapPanel.Children.Add(btn1)
myWrapPanel.Children.Add(btn2)
myWrapPanel.Children.Add(btn3)
myWrapPanel.Children.Add(btn4)

' Add the WrapPanel to the Page as Content
Me.Content = myWrapPanel

<Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" WindowTitle="WrapPanel Sample">
  <Border HorizontalAlignment="Left" VerticalAlignment="Top" BorderBrush="Black" BorderThickness="2">
        <WrapPanel Background="LightBlue" Width="200" Height="100">
            <Button Width="200">Button 1</Button>
            <Button>Button 2</Button>
            <Button>Button 3</Button>
            <Button>Button 4</Button>
        </WrapPanel>
  </Border>    
</Page>

Hinweise

Wenn die Orientation Eigenschaft auf Horizontal", untergeordnete Inhaltsformulare zuerst horizontale Zeilen und bei Bedarf vertikale Stapel von Zeilen bildet. Wenn die Eigenschaft auf Vertical"Festgelegt" festgelegt ist, wird der untergeordnete Inhalt zuerst in einer vertikalen Spalte positioniert, und wenn nicht genügend Platz vorhanden ist, tritt der Orientation Umbruch auf, und zusätzliche Spalten in der horizontalen Dimension werden hinzugefügt.
