Pardus GNOME Greeter is a welcome tour application designed to help users customize and configure their Pardus installation with just a few clicks. It runs automatically on the first login and guides the user through essential settings.

• Language: Python 3
• UI Toolkit: GTK4 + LibAdwaita (via PyGObject)
• Build System: Meson
• Configuration: GSettings

The application is built using modern GNOME technologies and follows a modular architecture:

1. Main Window: Built using Adw.ApplicationWindow and Adw.SplitView to ensure responsiveness. It adapts to different screen sizes (desktop/mobile) automatically.
2. Navigation: Uses Adw.ViewStack to manage different pages (Welcome, Wallpaper, Theme, etc.). The sidebar (Gtk.ListBox) controls the view stack.
3. Pages: Each step in the tour is a separate class located in src/pardus_gnome_greeter/pages/. These classes handle the UI logic for specific settings.
4. Managers: The core logic for applying settings is separated into "Managers" located in src/pardus_gnome_greeter/managers/. These managers handle interactions with the system (e.g., changing wallpaper via GSettings, managing extensions).

The project is designed to be reusable. You can import the internal managers in your own Python scripts to programmatically control GNOME settings:

from pardus_gnome_greeter.managers import ThemeManager, WallpaperManager

# Initialize managers
theme_manager = ThemeManager()
wallpaper_manager = WallpaperManager()

# Change the system theme
if theme_manager.set_gtk_theme("Adwaita"):
    print("Theme changed successfully!")

# Change the wallpaper
if wallpaper_manager.set_wallpaper("/usr/share/backgrounds/pardus/pardus-default.png"):
    print("Wallpaper updated!")
