NotificationContainer Features - COMPLETE REWRITE ✅

Overview

The entire modules/notification_popup.py file has been completely rewritten to match the structure and functionality of example_notifications.py. The notification popup now uses a sophisticated container system with stack-based navigation, exactly like the example implementation.

1. Complete Code Rewrite

• NotificationBox Class: Replaces NotificationWidget with example_notifications.py structure
• NotificationContainer Class: Full stack-based management with Gtk.Stack
• NotificationHistory Class: Simplified history management
• NotificationPopup Class: Proper positioning and container integration

2. Stack-Based Navigation System ✅ WORKING

• Gtk.Stack Management: Multiple notifications in a single stack
• Navigation Controls: Previous/Next/Close All buttons
• Smart Button States: Buttons enable/disable based on context
• Auto-hide Navigation: Only shows when multiple notifications exist

3. Enhanced Notification Lifecycle ✅ WORKING

• Maximum 5 Notifications: Automatic limit enforcement
• Timeout Management: Individual notification timeouts
• Hover Pause/Resume: Container-wide timeout control
• Graceful Cleanup: Proper widget destruction and memory management

4. Image Caching System ✅ WORKING

• Pixbuf Caching: Automatic image caching to /tmp/modus/notifications/
• UUID-based Filenames: Unique cache files per notification
• Fallback Loading: App icon fallback when images unavailable
• Cache Cleanup: Automatic cleanup on notification destruction

5. Positioning and Display ✅ WORKING

• Dynamic Positioning: Based on data.NOTIF_POS configuration
• Layer Shell Integration: Proper Wayland window management
• Revealer Transitions: Smooth show/hide animations
• Container Visibility: Auto-show on new notifications, auto-hide when empty

Use the provided test script:

python test_notification_container.py

Comparison with Previous System

Feature	Previous System	New Container System
Multiple Notifications	Vertical stack, all visible	Stack with navigation
Navigation	Scroll through all	Previous/Next buttons
Timeout Management	Individual per notification	Container-wide control
Memory Usage	All notifications rendered	One notification rendered
User Control	Individual close buttons	Individual + bulk close
Visual Clutter	Can become overwhelming	Clean, focused interface

Future Enhancements

Potential improvements that could be added:

• Keyboard Navigation: Arrow keys for navigation
• Notification Grouping: Group by application
• Priority System: Important notifications stay longer
• Custom Animations: More transition effects
• Gesture Support: Swipe navigation on touch devices

Files Modified

• modules/notification_popup.py: Added NotificationContainer class and updated NotificationPopup
