This adds a find_item_by_text() function to ItemList, so an item can be...found by text :D.
It'll return the index or -1 when nothing's found.
item-list-test.zip

Test project ^^^ here, script is attached and just demonstrates the basics.

This PR also addresses what appeared to be buggy or incomplete code regarding the Line Separation theme override on the ItemList:

This applies to the line separation within the list items, to be clear.

The existing behavior is odd, only enabled when the Icon Mode was set to Top:

...and when set to top, the behavior was off. For example, the separation between the lines would be multiplied by the Max Text Lines value:
image

...which I don't think made any sense. You can see the pre-existing behavior by setting Icon Mode to Top, setting the Line Separation enabled & a value > 0, then tick up Max Text Lines. You'll see the separation change thus.

This should be fixed up with this PR, and the Line Separation will also work regardless of the icon mode.

Summary by CodeRabbit

  • New Features
    • Added a way to find an item by its exact text and retrieve its index.
  • Improvements
    • Item text can now wrap across multiple lines in any icon mode when the line limit is greater than one and the item has a width constraint. Line spacing now applies between wrapped text lines.

Walkthrough

ItemList now supports multiline text wrapping across icon modes and adjusts item sizing for text width constraints. It also adds find_item_by_text, which returns the index of the first exact text match or -1.

Changes

ItemList text wrapping

Layer / File(s) Summary
Text wrapping and item sizing
scene/gui/item_list.cpp, doc/classes/ItemList.xml
Text wrapping now depends on max_text_lines and reshapes item text when wrapping settings change. Item sizing accounts for line limits and fixed column width. The documentation describes wrapping conditions and line spacing.

ItemList text lookup

Layer / File(s) Summary
Exact-text lookup method
scene/gui/item_list.h, scene/gui/item_list.cpp, doc/classes/ItemList.xml
find_item_by_text returns the first index whose item text exactly matches the input, or -1 when there is no match. The method is declared, bound, and documented.

Maximum lines of text allowed in each item. Space will be reserved even when there is not enough lines of text to display.
[b]Note:[/b] This property takes effect only when [member icon_mode] is [constant ICON_MODE_TOP]. To make the text wrap, [member fixed_column_width] should be greater than zero.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Update the class description to match the new wrapping behavior.

Line 425 says text can wrap outside ICON_MODE_TOP and without fixed_column_width. The class description at Line 9 still says both settings are required. Update Line 9 so users do not follow the obsolete restriction.
