RadioButtonPreference

RadioButtonPreference is a radio button component in Miuix that provides a title, summary, and radio button control. It supports click interactions and is commonly used in single-select settings and selection lists. When an item is selected, its title and summary are tinted with the theme color.

Import

import top.yukonga.miuix.kmp.preference.RadioButtonPreference

Basic Usage

RadioButtonPreference is typically used within a mutually exclusive group, with each option placed in its own card:

val options = listOf("Option A", "Option B", "Option C")
var selectedIndex by remember { mutableIntStateOf(0) }

options.forEachIndexed { index, option ->
    Card(
        modifier = Modifier.padding(bottom = 12.dp)
    ) {
        RadioButtonPreference(
            title = option,
            selected = selectedIndex == index,
            onClick = { selectedIndex = index }
        )
    }
}

RadioButton with Summary

var selectedIndex by remember { mutableIntStateOf(0) }

RadioButtonPreference(
    title = "Option A",
    summary = "Description for option A",
    selected = selectedIndex == 0,
    onClick = { selectedIndex = 0 }
)

Component States

Disabled State

RadioButtonPreference(
    title = "Disabled RadioButton",
    summary = "This radio button is currently unavailable",
    selected = true,
    onClick = {},
    enabled = false
)

var showDialog by remember { mutableStateOf(false) }
var selectedTheme by remember { mutableIntStateOf(0) }
val themes = listOf("Light", "Dark", "System")

        holdDownState = showDialog
    )

    OverlayDialog(

        show = showDialog,
        onDismissRequest = { showDialog = false }
    ) {
        Card {
            themes.forEachIndexed { index, theme ->
                RadioButtonPreference(
                    title = theme,
                    selected = selectedTheme == index,

            modifier = Modifier.padding(top = 12.dp)
        ) {
            TextButton(
                text = "Cancel",
                onClick = { showDialog = false },
                modifier = Modifier.weight(1f)
            )
            Spacer(Modifier.width(16.dp))
            TextButton(
                text = "Confirm",
                onClick = { showDialog = false },
