TUI Navigation and Consistency Fixes Summary

Issues Fixed

1. ✅ Arrow Keys and Space Bar Navigation

Problem: Arrow keys and space bar were not working due to a bug in the key_matches function.

Fix: Updated lib/tui/utils.py:

  • Fixed key_matches to only use chr() for printable ASCII (32-126)
  • Properly handle special keys by their parsed names
  • Arrow keys (259-261) now work correctly

2. ✅ ESC Key Handling and Exit Flow

Problem: ESC wasn't properly exiting and aborting workflows.

Fix: Updated lib/tui/unified_menu.py:

  • Changed run() to return exit codes (0 for success, 1 for cancel)
  • ESC now properly quits with cancel status
  • Multiple ESC presses handled gracefully

3. ✅ Fresh Install Abort Flow

Problem: When user pressed ESC in Fresh Install, the installation continued anyway.

Fix: Updated setup.sh:

  • fresh_install() now checks return code from run_configuration_wizard()
  • If user cancels (exit code != 0), the function returns immediately
  • No more unwanted continuation to Ansible playbooks

4. ✅ Inconsistent Menus

Problem: Different menus used different TUI systems (MenuDialog, SelectionOverlay, etc.)

Fixes:

  • Created lib/tui/main_menu.py - Unified main menu with splash screen
  • Created lib/tui/section_selector.py - Unified section selector for Modify Setup
  • Updated show_ubootu_splash() to use unified main menu
  • Updated modify_setup() to use unified section selector
  • All menus now use the same rendering engine

5. ✅ Consistent Visual Style

All menus now have:

  • Same box drawing characters (single-line: ┌─┐)
  • Same selection indicators ([X] for selected, [ ] for unselected)
  • Same help bar at bottom
  • Same navigation keys
  • Same visual layout
