ReadOnlyToggleGroupPropertyWrapper
class ReadOnlyToggleGroupPropertyWrapper(wraps: ToggleGroupProperty) : ReadOnlyPropertyWrapper<ToggleGroup, Property<ToggleGroup>> , ReadOnlyToggleGroupProperty
Never use this class directly. Use ToggleGroupProperty.asReadOnly to obtain a read-only version of a mutable ToggleGroupProperty.
Boilerplate which avoids having to use generic. Instead of ReadOnlyPropertyWrapper<ToggleGroup, Property<ToggleGroup>>, use ReadOnlyToggleGroupPropertyWrapper.
