# Documentation: DockPanelHorizontalView

## 1. Purpose

`DockPanelHorizontalView` is a WPF view component representing a horizontal dock panel within the DTS Viewer application. It serves as a UI container for horizontally-arranged docked elements, implementing the `IDockPanelHorizontalView` interface to integrate with the broader docking system architecture. This module exists to provide the code-behind logic for the corresponding XAML view definition.

## 2. Public Interface

### Class: `DockPanelHorizontalView`

**Kind:** `partial class`  
**Implements:** `IDockPanelHorizontalView`  
**Namespace:** `DTS.Viewer`

#### Constructor

```csharp
public DockPanelHorizontalView()
```

Initializes a new instance of the `DockPanelHorizontalView` class. Invokes `InitializeComponent()`, which loads and instantiates the XAML-defined UI component tree.

---

## 3. Invariants

- The class is declared as `partial`, indicating that additional implementation is auto-generated from the companion XAML file (`DockPanelHorizontalView.xaml`) at build time.
- `InitializeComponent()` must be called exactly once during construction; this is enforced by WPF's code-generation pattern.
- The class implements `IDockPanelHorizontalView`, implying it must fulfill any contract defined by that interface (interface members are not visible in this source file).

## 4. Dependencies

### This module depends on:
- `DTS.Common.Base` — imported but no specific types are referenced in this file; usage unclear from source alone
- `DTS.Common.Interface` — provides `IDockPanelHorizontalView` interface
- WPF Presentation Framework (implicit via `InitializeComponent()` pattern)

### What depends on this module:
- Cannot be determined from this source file alone. Likely consumed by a parent container or DI container within the `DTS.Viewer` assembly.

## 5. Gotchas

- The actual UI layout, visual tree, and any named elements are defined in the companion XAML file (`DockPanelHorizontalView.xaml`), which is not included here. The behavior and structure of this view cannot be fully understood without that file.
- The `IDockPanelHorizontalView` interface contract is not visible in this source; any required interface members (properties, methods, events) are not shown.
- The import of `DTS.Common.Base` is unused in this file—this may indicate dead code, a historical remnant, or types used in the XAML portion.
