# Classes
|
||
|
|
|
||
|
|
### Purpose
|
||
|
|
This module provides UI helper classes for the DTS Viewer WPF application. It includes a `BindingProxy` for enabling data binding in contexts where the data context is not directly accessible (e.g., within style setters), and a `ComponentsGroupControl` custom control for displaying grouped UI components with an image and title. Several placeholder classes (`MenuItem`, `TabItem`, `NavigationItem`) exist but contain no implementation.
|
||
|
|
|
||
|
|
### Public Interface
|
||
|
|
|
||
|
|
**BindingProxy** (inherits `Freezable`)
|
||
|
|
- `protected override Freezable CreateInstanceCore()` - Creates a new instance of `BindingProxy`. Required override for `Freezable` inheritance.
|
||
|
|
- `public static readonly DependencyProperty DataProperty` - Dependency property identifier for `Data`.
|
||
|
|
- `public object Data { get; set; }` - Gets or sets the data object to proxy for binding purposes.
|
||
|
|
|
||
|
|
**ComponentsGroupControl** (inherits `Control`)
|
||
|
|
- `public class ClickEventArgs : EventArgs` - Nested event args class with default constructor.
|
||
|
|
- `public static RoutedCommand ClickCommand { get; }` - Static routed command for click handling.
|
||
|
|
- `public static readonly DependencyProperty ImageProperty` - Dependency property identifier for `Image`.
|
||
|
|
- `public ImageSource Image { get; set; }` - Gets or sets the image source for the control.
|
||
|
|
- `public static readonly DependencyProperty TitleProperty` - Dependency property identifier for `Title`.
|
||
|
|
- `public string Title { get; set; }` - Gets or sets the title text; default value is "Title".
|
||
|
|
|
||
|
|
**MenuItem**
|
||
|
|
- No public members defined (empty class).
|
||
|
|
|
||
|
|
**TabItem**
|
||
|
|
- No public members defined (empty class).
|
||
|
|
|
||
|
|
**NavigationItem**
|
||
|
|
- No public members defined (empty class).
|
||
|
|
|
||
|
|
### Invariants
|
||
|
|
- `BindingProxy` must inherit from `Freezable` to participate in the WPF property system and support data binding in style setters.
|
||
|
|
- `ComponentsGroupControl` registers a default style key via `DefaultStyleKeyProperty.OverrideMetadata` in its static constructor, implying a XAML style/template must exist elsewhere.
|
||
|
|
- `ComponentsGroupControl.ClickCommand` is registered at the class level via `CommandManager.RegisterClassCommandBinding`.
|
||
|
|
|
||
|
|
### Dependencies
|
||
|
|
- **Depends on**: `System.Windows`, `System.Windows.Controls`, `System.Windows.Input`, `System.Windows.Media`.
|
||
|
|
- **Depended on by**: Unclear from source alone; likely used in DTS Viewer views and XAML templates.
|
||
|
|
|
||
|
|
### Gotchas
|
||
|
|
- **Commented-out code**: `ComponentsGroupControl` contains commented
