FlowDocumentScrollViewer Class
Definition
A read-only viewer that displays a Avalonia.Controls.Documents.FlowDocument inside a built-in Avalonia.Controls.ScrollViewer. Provides text selection and copy-to-clipboard support; no editing capabilities are exposed.
public class FlowDocumentScrollViewer
Remarks
The architecture mirrors RichTextEditor and Markdown: a
Avalonia.Controls.ScrollViewer wraps the inner Avalonia.Controls.Documents.Primitives.InteractiveTextView
which implements Avalonia.Controls.Primitives.ILogicalScrollable for virtualized scrolling.
Selection is driven by Avalonia.Controls.Documents.Primitives.Components.TextViewMouse and Avalonia.Controls.Documents.Primitives.Components.TextViewKeyboard components; selection rendering is provided by a Avalonia.Controls.Documents.Primitives.Highlighting.SelectionHighlightLayer registered on the inner Avalonia.Controls.Documents.Primitives.Adorners.BlockAdornerLayer.
The document's page bands and footnotes are documents of their own, shown by the same view. One selection at a time covers one of them: a press into a note or a band moves the selection there (Avalonia.Controls.FlowDocumentScrollViewer.ActiveDocument), Escape or a press into the body brings it back, and each document keeps its own selection while it belongs to the body.

public FlowDocumentScrollViewer()
Methods
| Name | Description |
|---|---|
| ActivateDocument | Makes document the document the selection covers: one of the body's page bands or footnotes, or the body itself when null. A nested document's selection is created the first time it is entered and kept while the document belongs to the body; the body's selection stays where it was. The caret moves to position when one is given. Returns false while selection is disabled, and for a document that is neither the body nor nested in it. |

| ApplyStyling | Applies styling to the control if the control is initialized and styling is not already applied. Inherited from StyledElement. |

ActivateDocument Method
Makes document the document the selection covers: one of
the body's page bands or footnotes, or the body itself when null. A nested
document's selection is created the first time it is entered and kept while
the document belongs to the body; the body's selection stays where it was.
The caret moves to position when one is given. Returns
false while selection is disabled, and for a document that is neither the
body nor nested in it.
public bool ActivateDocument(Avalonia.Controls.Documents.FlowDocument document, Avalonia.Controls.Documents.TextModel.TextPointer position)
Parameters
document Avalonia.Controls.Documents.FlowDocument
position Avalonia.Controls.Documents.TextModel.TextPointer
Returns
bool
ClearSelection Method
Clears the current selection.
public void ClearSelection()
Copy Method
Copies the current selection to the clipboard without waiting for the clipboard write.
public void Copy()
Remarks
Await Avalonia.Controls.FlowDocumentScrollViewer.CopyAsync(System.Threading.CancellationToken) instead. The clipboard is a platform resource another process can hold, so the write can fail after this method has already returned, and a caller here can neither see that nor sequence anything after it.
CopyAsync Method
Copies the current selection to the clipboard as plain text. The returned task completes once the clipboard write has, and faults with whatever the platform clipboard threw.
public System.Threading.Tasks.Task CopyAsync(System.Threading.CancellationToken cancellationToken)
Parameters
cancellationToken System.Threading.CancellationToken
Abandons the copy before the clipboard is written.
Returns
System.Threading.Tasks.Task
GetComponent Method
public T GetComponent<T>()
Type Parameters
T
Returns
T
RegisterComponent Method
Registers a component with this host.
public void RegisterComponent(Avalonia.Controls.Documents.Primitives.Components.ITextViewComponent component)
Parameters
component Avalonia.Controls.Documents.Primitives.Components.ITextViewComponent
The component to register.
Remarks
If the host is already in the attached state, the component receives an immediate Avalonia.Controls.Documents.Primitives.Components.ITextViewComponent.OnAttach(Avalonia.Controls.Documents.Primitives.IInteractiveTextHost) callback.
SelectAll Method
Selects the entire document.
public void SelectAll()
UnregisterComponent Method
Unregisters a component from this host.
public void UnregisterComponent(Avalonia.Controls.Documents.Primitives.Components.ITextViewComponent component)
Parameters
component Avalonia.Controls.Documents.Primitives.Components.ITextViewComponent
The component to unregister.
Remarks
If the component is currently attached, it receives an Avalonia.Controls.Documents.Primitives.Components.ITextViewComponent.OnDetach callback before removal.
