Definition

Namespace:Avalonia.Controls.Documents.Primitives.Adorners

Assembly:Avalonia.Controls.Documents

Package:Avalonia.Controls.Documents

Manages a Z-ordered set of Avalonia.Controls.Documents.Primitives.Adorners.BlockAdorner instances.

public class BlockAdornerCollection

Inheritance: object -> BlockAdornerCollection

Implements: IEnumerable<BlockAdorner>, IReadOnlyCollection<BlockAdorner>, IReadOnlyList<BlockAdorner>, IEnumerable

Remarks

Enumeration and the indexer walk the adorners in render order, lowest Avalonia.Controls.Documents.Primitives.Adorners.BlockAdorner.ZIndex first, with lazy sorting and change-event relay. The owning Avalonia.Controls.Documents.Primitives.Adorners.BlockAdornerLayer handles node iteration, filtering, and dispatch.
