Jazz2::UI::Menu::CustomValueItem class

#include <Jazz2/UI/Menu/MenuWidgets.h>

Setting row with a custom-drawn value.

Like ChoiceItem but draws its value through a caller-provided callback instead of plain text, for rows such as colour swatch pickers or a formatted identifier. Optionally cycles via OnChange (showing arrows) or activates via OnActivate (e.g., copying to the clipboard).
