Theme-wide style for every wheel, set through io.github.joelkanyi.jenga.theme.JengaComponentStyles.wheelPicker. A null value keeps Jenga's default; colors passed to a single call still win.

Functions

JengaDateOfBirthPicker

@Composable

fun JengaDateOfBirthPicker(value: LocalDate, onValueChange: (LocalDate) -> Unit, monthLabel: (Month) -> String, modifier: Modifier = Modifier, minDate: LocalDate = JengaDateOfBirthPickerDefaults.MinDate, maxDate: LocalDate = remember { JengaCalendarDefaults.today() }, order: JengaDateFieldOrder = JengaDateFieldOrder.DayMonthYear, dayContentDescription: String? = null, monthContentDescription: String? = null, yearContentDescription: String? = null, visibleItemCount: Int = JengaWheelPickerDefaults.VisibleItemCount, itemHeight: Dp = JengaWheelPickerDefaults.ItemHeight, colors: JengaWheelPickerColors = JengaWheelPickerDefaults.colors())

A date-of-birth picker: day, month and year scroll wheels side by side. The day is kept valid as the month or year changes (31 March becomes 28 or 29 February), and the date never leaves minDate..maxDate.

JengaTimeInput

@Composable

fun JengaTimeInput(time: LocalTime, onTimeChange: (LocalTime) -> Unit, hourLabel: String, minuteLabel: String, amLabel: String, pmLabel: String, modifier: Modifier = Modifier, style: JengaTimeInputStyle = JengaTimeInputStyle.Wheel, is24Hour: Boolean = false, minuteStep: Int = 1)

A time input: hour and minute, plus AM / PM in 12-hour mode, as scroll wheels or typed fields. Every visible string comes from the caller.

JengaTimePickerDialog

@Composable

fun JengaTimePickerDialog(onDismissRequest: () -> Unit, onConfirm: (LocalTime) -> Unit, title: String, confirmLabel: String, dismissLabel: String, initialTime: LocalTime, hourLabel: String, minuteLabel: String, amLabel: String, pmLabel: String, modifier: Modifier = Modifier, style: JengaTimeInputStyle = JengaTimeInputStyle.Wheel, is24Hour: Boolean = false, minuteStep: Int = 1)

A dialog holding a JengaTimeInput, with dismiss and confirm actions. The time is only reported when the confirm action is tapped.

JengaWheelPicker

@Composable

fun <T> JengaWheelPicker(items: List<T>, selectedIndex: Int, onSelectedIndexChange: (Int) -> Unit, modifier: Modifier = Modifier, itemLabel: (T) -> String = { it.toString() }, contentDescription: String? = null, visibleItemCount: Int = JengaWheelPickerDefaults.VisibleItemCount, itemHeight: Dp = JengaWheelPickerDefaults.ItemHeight, selectionShape: Shape = JengaWheelPickerDefaults.selectionShape, textStyle: TextStyle = JengaWheelPickerDefaults.textStyle, colors: JengaWheelPickerColors = JengaWheelPickerDefaults.colors(), itemContent: @Composable (item: T, selected: Boolean) -> Unit = { item, selected -> JengaText( text = itemLabel(item), style = textStyle, color = if (selected) colors.selectedContent else colors.content, maxLines = 1, ) })

A scroll wheel for picking one of items: rows scroll vertically and snap so one sits in the highlighted middle band. Tapping a row scrolls it into the middle. For accessibility the wheel is a single adjustable control whose value is the selected row's label.
