Exemples

L’exemple suivant montre comment définir la Orientation propriété dans XAML (Extensible Application Markup Language).

<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>

L’exemple suivant montre comment définir la propriété à l’aide Orientation du code.

// 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"

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()

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

        </WrapPanel>
  </Border>

Remarques

Si la propriété est définie sur Horizontal, le Orientation contenu enfant forme d’abord des lignes horizontales et si nécessaire forme des piles verticales de lignes. Si la propriété est définie sur Vertical, le contenu enfant est d’abord positionné dans une colonne verticale, et s’il n’y a pas suffisamment d’espace, l’encapsulation Orientation se produit et des colonnes supplémentaires dans la dimension horizontale sont ajoutées.
