# Documentation: PSDReportSettingsView

## 1. Purpose

`PSDReportSettingsView` is a WPF view component that provides the user interface for configuring PSD (Power Spectral Density) report settings. It implements the `IPSDReportSettingsView` interface and serves as the visual layer for users to select parameters such as window widths for spectral analysis. This view is part of the DTS Viewer reporting subsystem.

## 2. Public Interface

### `PSDReportSettingsView()` (Constructor)
**Signature:** `public PSDReportSettingsView()`

Initializes the view component by calling `InitializeComponent()`, which loads the associated XAML layout.

### `AvailableWindowWidths` (Property)
**Signature:** `public List<int> AvailableWindowWidths { get; }`

Returns a hardcoded list of valid FFT window width options: `{ 512, 1024, 2048, 4096, 8196 }`. These values represent the sample counts available for windowing operations in PSD analysis.

## 3. Invariants

- The `AvailableWindowWidths` property always returns a new `List<int>` instance containing exactly five integer values: 512, 1024, 2048, 4096, and 8192.
- The view must be constructed on the UI thread due to the `InitializeComponent()` call.
- The class implements `IPSDReportSettingsView`, implying it is intended to be consumed through that interface by a presenter or view model.

## 4. Dependencies

### This module depends on:
- `DTS.Common.Interface` - Provides the `IPSDReportSettingsView` interface that this class implements
- `Xceed.Wpf.Toolkit.PropertyGrid.Attributes` - Imported but **not used** in the visible source
- `System.Collections.Generic` - Provides `List<T>` for the `AvailableWindowWidths` property

### What depends on this module:
- Cannot be determined from source alone. Consumers would reference this view through the `IPSDReportSettingsView` interface.

## 5. Gotchas

- **Unused import:** The `Xceed.Wpf.Toolkit.PropertyGrid.Attributes` namespace is imported but has no visible usage in the current code. This may indicate leftover references from removed functionality.

- **Commented-out code:** Three properties (`AvailablePassFilterTypes`, `AvailableWindowAveragingTypes`, `AvailableWindowTypes`) are fully commented out, suggesting this view previously exposed more configuration options. The commented code references types `DTS.Common.Enums.Viewer.Reports.PassFilterTypeEnumItemSource`, `WindowAveragingTypeEnumItemSource`, and `WindowTypeEnumItemSource` that may still exist in the codebase.

- **New list instance per call:** `AvailableWindowWidths` creates and returns a new `List<int>` on every property access rather than returning a cached or static instance. This is inefficient if called frequently.
