Przykłady

Poniższy przykład pokazuje, jak używać wartości elementów członkowskich tego wyliczenia, aby ustawić właściwość HorizontalScrollBarVisibility formantu ScrollViewer.The following example shows how to use the member values of this enumeration to set the HorizontalScrollBarVisibility property of the ScrollViewer control.


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

// Define a ScrollViewer
myScrollViewer = gcnew ScrollViewer();
myScrollViewer->HorizontalScrollBarVisibility = ScrollBarVisibility::Auto;

// Add Layout control
myStackPanel = gcnew StackPanel();
myStackPanel->HorizontalAlignment = HorizontalAlignment::Left;
myStackPanel->VerticalAlignment = VerticalAlignment::Top;

TextBlock^ myTextBlock = gcnew TextBlock();
myTextBlock->TextWrapping = TextWrapping::Wrap;
myTextBlock->Margin = System::Windows::Thickness(0, 0, 0, 20);
myTextBlock->Text = "Scrolling is enabled when it is necessary. Resize the Window, making it larger and smaller.";

Rectangle^ myRectangle = gcnew Rectangle();
myRectangle->Fill = Brushes::Red;
myRectangle->Width = 500;
myRectangle->Height = 500;

// Add child elements to the parent StackPanel
myStackPanel->Children->Add(myTextBlock);
myStackPanel->Children->Add(myRectangle);

// Add the StackPanel as the lone Child of the Border
myScrollViewer->Content = myStackPanel;

// Add the Border as the Content of the Parent Window Object
mainWindow->Content = myScrollViewer;
mainWindow->Show();


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

// Define a ScrollViewer
myScrollViewer = new ScrollViewer();
myScrollViewer.HorizontalScrollBarVisibility = ScrollBarVisibility.Auto;

// Add Layout control
myStackPanel = new StackPanel();
myStackPanel.HorizontalAlignment = HorizontalAlignment.Left;
myStackPanel.VerticalAlignment = VerticalAlignment.Top;

TextBlock myTextBlock = new TextBlock();
myTextBlock.TextWrapping = TextWrapping.Wrap;
myTextBlock.Margin = new Thickness(0, 0, 0, 20);
myTextBlock.Text = "Scrolling is enabled when it is necessary. Resize the Window, making it larger and smaller.";

Rectangle myRectangle = new Rectangle();
myRectangle.Fill = Brushes.Red;
myRectangle.Width = 500;
myRectangle.Height = 500;

// Add child elements to the parent StackPanel
myStackPanel.Children.Add(myTextBlock);
myStackPanel.Children.Add(myRectangle);
            
// Add the StackPanel as the lone Child of the Border
myScrollViewer.Content = myStackPanel;

// Add the Border as the Content of the Parent Window Object
mainWindow.Content = myScrollViewer;
mainWindow.Show ();

Uwagi

To Wyliczenie służy do ustawiania wartości właściwości HorizontalScrollBarVisibility i VerticalScrollBarVisibility kontrolki ScrollViewer.Use this enumeration to set the HorizontalScrollBarVisibility and VerticalScrollBarVisibility property values of the ScrollViewer control.

Wartości elementu członkowskiego tego wyliczenia określają ScrollBar widoczność w danym kierunku.The member values of this enumeration specify ScrollBar visibility in a given direction. Te wartości elementów członkowskich określają również, czy odpowiedni wymiar ScrollViewer jest stosowany do jego zawartości.These member values also specify whether the corresponding ScrollViewer dimension is applied to its enclosed content.

Po zastosowaniu ViewportWidth lub ViewportHeight do ScrollViewer zawartości należy ustawić rozmiar okienka ekranu dla zawartości.When you apply the ViewportWidth or ViewportHeight to ScrollViewer content, you set the viewport size for the content.
