ui.NewCheckboxGroup(props ...CheckboxGroupProps) *CheckboxGroupComponent

NewCheckboxGroup declares a CheckboxGroup instance. Optional props provide initial settings.

Reffunc(*native.Node)—

Receives the retained native node after construction. Keep imperative work in event or lifecycle callbacks.
