`NewRadioGroup`

查看源码

ui.NewRadioGroup(props ...RadioGroupProps) *RadioGroupComponent

NewRadioGroup declares a RadioGroup instance. Optional props provide initial settings.

Reffunc(*native.Node)—

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

func(*native.Node)

查看源码

Styleany—

Reusable layout, typography, color, and interaction-state styles. Build with ui.Style() and compose with Merge.

any

查看源码

ChildrenPartChildren—

Content mounted inside the component. Compound child callbacks run after the parent context exists.

PartChildren
