# Documentation: DTS.Common.Interface Viewer Interfaces

## 1. Purpose

This module defines the view and ViewModel interfaces for a Viewer component within the DTS system. It establishes the contract for a Model-View-ViewModel (MVVM) architecture, providing interfaces for main shell composition, navigation, menu handling, filtering, and test summary list display. The interfaces support a region-based UI composition pattern where different views can be injected into named context regions.

## 2. Public Interface

### View Interfaces

All view interfaces inherit from `IBaseView` (defined in `DTS.Common.Base`) and currently define no additional members.

| Interface | File |
|-----------|------|
| `IMainView` | `IMainView.cs` |
| `IMenuView` | `IMenuView.cs` |
| `IFilterView` | `IFilterView.cs` |
| `INavigationView` | `INavigationView.cs` |
| `ITestSummaryListView` | `ITestDefinitionListView.cs` |
