Summary

Refactored the demo application class to simplify its structure by consolidating separate methods into the main method and removing unnecessary protected section methods.

Key Changes

  • Removed method fragmentation: Consolidated display_view(), on_event(), and z2ui5_set_data() methods into the z2ui5_if_app~main() method
  • Simplified class structure: Removed the protected section entirely, eliminating the client instance variable and related method declarations
  • Improved code flow: Combined initialization, data setup, view creation, and event handling into a single linear flow within the main method
  • Code style improvements:
    • Changed string literals from single quotes to backticks for consistency
    • Removed excessive blank lines
    • Removed CREATE PUBLIC from class definition (now uses default)
    • Improved method parameter formatting and indentation

Implementation Details

The refactoring maintains the same functional behavior while reducing complexity:

  • Data initialization (product and quantity) now happens directly in the main method
  • View creation and display logic is inlined
  • Event handling for BUTTON_POST is now part of the main method's conditional logic
  • The code is more readable with a clear sequential flow: check initialization → setup data → create view → display view → handle events

- Remove CREATE PUBLIC from class definition
- Replace single quotes with backticks throughout
- Replace separate IF blocks with ELSEIF chain in main()
- Rename display_view to view_display, inline z2ui5_set_data logic
- Remove client importing parameters from methods (use attribute instead)
- Extract view->stringify() as standalone statement
- Fix blank line rules (method bodies, before IF/ELSEIF, between sections)
- Remove FINAL keyword pattern (was not present, now correctly absent)

Per guidelines: simple apps with < 50 lines in main need no method
encapsulation. Remove view_display method and client attribute.

https://claude.ai/code/session_01LpJmSaujwdpe7AaFabLpzA
- Remove CREATE PUBLIC from class definition
- Move client attribute to PROTECTED SECTION
- Remove Hungarian notation: mt_suggestion->suggestions, mt_combo->combo,
  s_suggestion_items->suggestion_item, s_combobox->combobox_item, lv_test removed
- Remove ty_t_combo type alias (inline type used directly)
- Rename methods: z2ui5_on_init->on_init, z2ui5_on_event->on_event,
  z2ui5_on_rendering->view_display
- Replace single quotes with backticks throughout
- Fix main() to use ELSEIF chain instead of separate IF + unconditional call
- Move combo initialization from view_display to on_init
- Eliminate get_parent() calls by using page reference directly for second grid
- Rename local variable lv_test: use content reference directly for form fields
- Call view->stringify() instead of page->stringify()
- Fix blank line rules throughout
