Syntax

public interface IPresenter : IControl, IDataTemplateHost, ILayoutable, IInputElement, 
    IInteractive, IVisual, IStyledElement, IStyleable, IStyleHost, ILogical, IResourceHost, 
    IResourceNode, IDataContextProvider, IAvaloniaObject, ISupportInitialize, INamed

Remarks

A presenter is the gateway between a templated control and its content. When a control which implements IPresenter is found in the template of a TemplatedControl then that signals that the visual child of the presenter is not a part of the template.
