# Documentation: DatabaseImport Application Module
|
||
|
|
|
||
|
|
## 1. Purpose
|
||
|
|
|
||
|
|
This module provides UI state management utilities for a WPF-based database import application. It consists of two components: `WaitCursor`, a disposable utility class for temporarily displaying a wait cursor with automatic restoration, and `App`, the main application class that manages application-wide busy states, provides lazy-initialized access to an `ISO13499FileDb` instance, and handles thread-safe UI manipulation through dispatcher-aware methods.

| Constructor | `public WaitCursor()` | Saves the current `Mouse.OverrideCursor` value to `_previousCursor`, then sets `Mouse.OverrideCursor` to `Cursors.Wait`. |
|
||
|
|
| `Dispose` | `public void Dispose()` | Restores the cursor by setting `Mouse.OverrideCursor` back to the saved `_previousCursor` value. |
