# BeeWare GUI Adapter
SeedPass ships with a proof-of-concept graphical interface built using [BeeWare](https://beeware.org). The GUI interacts with the same core services as the CLI by instantiating wrappers around `PasswordManager`.
## Getting Started with the GUI
After installing the project dependencies, launch the desktop interface with one
of the following commands:
```bash
seedpass gui
python -m seedpass_gui
seedpass-gui
```
The GUI shares the same encrypted vault and configuration as the command line tool.
To generate a packaged binary, run `briefcase build` (after the initial `briefcase create`).
```mermaid

gui --> core
api --> core
ext --> api
```
## VaultService and EntryService
`VaultService` provides thread-safe access to vault operations like exporting, importing, unlocking and locking the vault. `EntryService` exposes methods for listing, searching and modifying entries. Both classes live in `seedpass.core.api` and hold a `PasswordManager` instance protected by a `threading.Lock` to ensure safe concurrent access.
```python
class VaultService:
"""Thread-safe wrapper around vault operations."""
def __init__(self, manager: PasswordManager) -> None:
self._manager = manager
self._lock = Lock()
```
```python
class EntryService:
"""Thread-safe wrapper around entry operations."""
def __init__(self, manager: PasswordManager) -> None:
self._manager = manager
self._lock = Lock()
```
## BeeWare Windows
The GUI defines two main windows in `src/seedpass_gui/app.py`. `LockScreenWindow` prompts for the master password and then opens `MainWindow` to display the vault entries.
```python
class LockScreenWindow(toga.Window):
"""Window prompting for the master password."""
def __init__(self, app: SeedPassApp, vault: VaultService, entries: EntryService) -> None:
super().__init__("Unlock Vault")
self.app = app
self.vault = vault
self.entries = entries
...
```
```python
class MainWindow(toga.Window):
"""Main application window showing vault entries."""
def __init__(self, app: SeedPassApp, vault: VaultService, entries: EntryService) -> None:
super().__init__("SeedPass")
self.app = app
self.vault = vault
self.entries = entries
...
```
Each window receives the service instances and calls methods such as `vault.unlock()` or `entries.add_entry()` when buttons are pressed. This keeps the UI thin while reusing the core logic.
## Asynchronous Synchronization
`PasswordManager` performs network synchronization with Nostr using `asyncio`. Methods like `start_background_vault_sync()` create a coroutine that calls `sync_vault_async()` in a background thread or task without blocking the UI.
```python
async def sync_vault_async(self, alt_summary: str | None = None) -> dict[str, list[str] | str] | None:
"""Publish the current vault contents to Nostr and return event IDs."""
...
```
```python
def start_background_vault_sync(self, alt_summary: str | None = None) -> None:
if getattr(self, "offline_mode", False):
return
def _worker() -> None:
asyncio.run(self.sync_vault_async(alt_summary=alt_summary))
try:
loop = asyncio.get_running_loop()
except RuntimeError:
threading.Thread(target=_worker, daemon=True).start()
else:
asyncio.create_task(self.sync_vault_async(alt_summary=alt_summary))
```
This approach ensures synchronization happens asynchronously whether the GUI is running inside or outside an existing event loop.
## Relay Manager and Status Bar
The *Relays* button opens a dialog for adding or removing Nostr relay URLs. The
status bar at the bottom of the main window shows when the last synchronization
completed. It updates automatically when `sync_started` and `sync_finished`
events are published on the internal pubsub bus.
When a ``vault_locked`` event is emitted, the GUI automatically returns to the
lock screen so the session can be reopened with the master password.
