Interface

Documentation: RibbonControl Interface Module

1. Purpose

This module defines foundational interfaces for the ribbon UI control layer within the DTS system. It establishes a contract-based abstraction for ribbon-related view and view model components, enabling separation of concerns between UI presentation (via IRibbonView) and business logic/data (via IRibbonViewModel), while supporting tab identification through IRibbonTabInfoProvider. The interfaces are part of a larger MVVM (Model-View-ViewModel) architecture, inheriting from base interfaces (IBaseView, IBaseViewModel) to ensure consistency across the application’s UI framework.

2. Public Interface

• IRibbonView

  public interface IRibbonView : IBaseView
  

  Represents the view layer for the ribbon control. It inherits from IBaseView, implying it participates in the base view lifecycle and contract (e.g., data binding, lifecycle events), though its specific behavior is not defined here. No additional members beyond inheritance.

• IRibbonTabInfoProvider

  public interface IRibbonTabInfoProvider
  {
      string RibbonTabUid { get; }
  }
  

  Provides a standardized way to retrieve a unique identifier (RibbonTabUid) for a ribbon tab. Implementers expose this read-only property to allow consumers (e.g., tab management logic) to locate or reference a specific ribbon tab unambiguously.

• IRibbonViewModel

  public interface IRibbonViewModel : IBaseViewModel
  {
      IRibbonView View { get; }
  }
  

  Serves as the view model for the ribbon control. It enforces a strict relationship with its associated view via the View property, ensuring the view model always exposes its bound view instance. Inherits from IBaseViewModel, implying it supports base view model functionality (e.g., property change notification, command handling).

3. Invariants

• IRibbonView must be implemented by a concrete view class that adheres to the IBaseView contract (e.g., implements IBaseView members like Initialize, Load, Unload, etc., though these are not shown here).
• IRibbonTabInfoProvider.RibbonTabUid must return a non-null, non-empty string that uniquely identifies a ribbon tab within the application domain.
• IRibbonViewModel.View must never return null; it must always reference a valid instance of a type implementing IRibbonView.
• All interfaces are part of the DTS.Common.RibbonControl namespace and rely on DTS.Common.Base for base contracts (IBaseView, IBaseViewModel).

4. Dependencies

• Depends on:
  • DTS.Common.Base (specifically IBaseView, IBaseViewModel)
• Depended on by:
  • Concrete implementations of ribbon views (e.g., RibbonView : IRibbonView)
  • Concrete implementations of ribbon view models (e.g., RibbonViewModel : IRibbonViewModel)
  • Components responsible for ribbon tab management (e.g., services or controllers that consume IRibbonTabInfoProvider to locate tabs)
• Note: The source files themselves do not indicate direct usage by other modules, but the interfaces are clearly designed for integration into a larger ribbon UI system.

5. Gotchas

• Ambiguity in IBaseView/IBaseViewModel contracts: Since IRibbonView and IRibbonViewModel inherit from IBaseView and IBaseViewModel respectively, their full contract depends on definitions in DTS.Common.Base, which are not provided here. Behavior such as initialization order, lifecycle events, or property change semantics is assumed but not verifiable from this module alone.
• No explicit validation on RibbonTabUid: While the documentation states RibbonTabUid is a unique identifier, the interface does not enforce uniqueness at compile time or runtime. Implementers must ensure uniqueness to avoid runtime tab resolution errors.
• No method definitions: These interfaces are purely declarative (properties only). Any ribbon-specific logic (e.g., tab activation, command binding) is expected to be handled outside this interface layer.
• None identified from source alone.
