QCustomRadioGroup
A labelled set of single-choice options.
Owns a set of QCustomRadioButton children and the mutual exclusion between them, so the group - not the buttons - is the single source of truth for "what is selected". That matters in Qt Designer, where you cannot wire up sibling relationships by hand.
Options are authored in code with setOptions([...]) or in Qt Designer with the optionsCsv property, following the valuesCsv convention used by the chart widgets:
optionsCsv = "Free,Pro,Studio" labels double as values optionsCsv = "free=Free,pro=Pro,studio=Studio" explicit value=label
Emits valueChanged(str) and currentIndexChanged(int).
