# View
|
||
|
|
|
||
|
|
### Purpose
|
||
|
|
This module defines base classes for views in a WPF/Prism application. `BaseWindow` and `BaseView` provide common properties (`IsDirty`, `HeaderInfo`) that delegate to their respective DataContext interfaces, enabling consistent dirty-tracking and header display across windows and user controls.
|
||
|
|
|
||
|
|
### Public Interface
|
||
|
|
|
||
|
|
**BaseWindow** (extends `Window`, implements `IBaseWindow`)
|
||
|
|
- `public bool IsDirty { get; }` — Returns `true` if `DataContext` implements `IBaseWindowModel` and `baseWindowModel.IsDirty` is `true`; otherwise returns `false`.
|
||
|
|
- `public string HeaderInfo { get; }` — Returns `iHeaderInfoProvider.HeaderInfo` if `DataContext` implements `IHeaderInfoProvider<string>`; otherwise returns `string.Empty`.
|
||
|
|
|
||
|
|
**BaseView** (extends `UserControl`, implements `IBaseView`)
|
||
|
|
- `public bool IsDirty { get; }` — Returns `true` if `DataContext` implements `IBaseViewModel` and `baseViewModel.IsDirty` is `true`; otherwise returns `false`.
|
||
|
|
- `public string HeaderInfo { get; }` — Returns `headerInfoProvider.HeaderInfo` if `DataContext` implements `IHeaderInfoProvider<string>`; otherwise returns `string.Empty`.
|
||
|
|
|
||
|
|
### Invariants
|
||
|
|
- Both `IsDirty` and `HeaderInfo` properties are read-only getters with no setters.
|
||
|
|
- If `DataContext` is `null`, both properties return default values (`false` for `IsDirty`, `string.Empty` for `HeaderInfo`).
|
||
|
|
- `BaseWindow.IsDirty` checks for `IBaseWindowModel`; `BaseView.IsDirty` checks for `IBaseViewModel` — these are different interfaces.
|
||
|
|
|
||
|
|
### Dependencies
|
||
|
|
- **Depends on**: `System.Windows` (`Window`), `System.Windows.Controls` (`UserControl`), `DTS.Common.Base` (interfaces `IBaseWindow`, `IBaseView`, `IBaseWindowModel`, `IBaseViewModel`, `IHeaderInfoProvider<string>` — inferred from usage).
|
||
|
|
- **Depended on by**: Unclear from source alone—likely used as base classes for specific views/windows throughout the application.
|
||
|
|
|
||
|
|
### Gotchas
|
||
|
|
- **Interface mismatch**: `BaseWindow.IsDirty` checks for `IBaseWindowModel` while `BaseView.IsDirty` checks for `IBaseViewModel`. If a DataContext implements the wrong interface for the container type, `IsDirty` will incorrectly return `false`.
|
||
|
|
- **Namespace directive**: Source includes `// ReSharper disable once CheckNamespace` suggesting the file location may not match the declared namespace `DTS.Common.Base`.
