RadioGroup

class RadioGroup {
  public:
    void add(RadioButton *rb);
    void select(RadioButton *rb);
    std::function<void(int index)> on_change;
};

Create one RadioGroup per set of mutually-exclusive options; each RadioButton registers itself with the group it's constructed with.

Example

toolkit::RadioGroup group;
auto opt1 = std::make_unique<toolkit::RadioButton>("Option &1", group);
auto opt2 = std::make_unique<toolkit::RadioButton>("Option &2", group);
group.on_change = [](int index) { /* ... */ };

Construction

RadioButton(std::string text, RadioGroup &group);
