# DTS.Common.Interface Documentation

## 1. Purpose

This module defines the abstraction layer for the DTS Viewer application's presentation components. It establishes the contract interfaces for Views, ViewModels, and Modules following the Model-View-ViewModel (MVVM) pattern with Prism framework integration. The interfaces enable loose coupling between UI components, support dependency injection, and define the structure for modular plug-in architecture including export, viewer, and PSD report modules.

## 2. Public Interface

### View Interfaces

All view interfaces inherit from `IBaseView` (defined in `DTS.Common.Base`) and serve as markers for view resolution:

| Interface | Description |
|-----------|-------------|
| `ITabView` | Marker interface for tab views |
| `IDiagView` | Marker interface for diagnostic views |
| `ITestsView` | Marker interface for test views |
| `IStatsView` | Marker interface for statistics views |
| `ICursorView` | Marker interface for cursor views |
| `IViewerView` | Marker interface for viewer views |
| `ITabItemView` | Marker interface for individual tab item views |
| `IPropertyView` | Marker interface for property views |
| `IViewerShellView` | Marker interface for the main shell view |
| `IGraphPropertyView` | Marker interface for graph property views |
| `IDockPanelVerticalView` | Marker interface for vertical dock panel views |
| `IDockPanelHorizontalView` | Marker interface for horizontal dock panel views |
| `IMainViewerView` | Marker interface for main viewer views (members commented out) |

#### `IMainLiteView`

```csharp
public interface IMainLiteView : IBaseView
{
    StackPanel MainShell { get; set; }
    ContentControl MainRegion { get; set; }
    ContentControl NavigationRegion { get; set; }
    ContentControl HorizontalTabRegion { get; set; }
    ContentControl VerticalTabRegion { get; set; }
}
```

Exposes named region controls for view composition in a "lite" version of the main view.

### ViewModel Interfaces

All ViewModel interfaces inherit from `IBaseViewModel` (defined in `DTS.Common.Base`):

#### `ITabViewModel`
```csharp
public interface ITabViewModel : IBaseViewModel
{
    ITabView View { get; }
}
```

#### `IDiagViewModel`
```csharp
public interface IDiagViewModel : IBaseViewModel
{
    IDiagView View { get; }
}
```

#### `IStatsViewModel`
```csharp
public interface IStatsViewModel : IBaseViewModel
{
    IStatsView View { get; }
}
```

#### `ICursorViewModel`
```csharp
public interface ICursorViewModel : IBaseViewModel
{
    ICursorView View { get; }
}
```

#### `ITestsViewModel`
```csharp
public interface ITestsViewModel : IBaseViewModel
{
    ITestsView View { get; }
}
```

#### `IViewerViewModel`
```csharp
public interface
