#Import

Import ui from github.com/egoist/quickgui/go/ui.

import (
	"github.com/egoist/quickgui/go/native"
	"github.com/egoist/quickgui/go/ui"
)

#Usage

func RadioExample() *ui.Element {
	value, setValue := ui.CreateSignal("system")
	group := ui.NewRadioGroup(ui.RadioGroupProps{Value: func() *string {
		current := value()
		return &current
	}, OnValueChange: func(next string, _ *native.Event) {
		setValue(next)
	}})
	options := make([]*ui.Element, 0, 3)
	for _, value := range []string{"light", "dark", "system"} {
		radio := ui.NewRadio().Value(value)
		options = append(options, radio.Root().Children(
			radio.Indicator(),
			ui.Text(value),
		))
	}
	return group.Root().Children(options)
}
