Auto hide thumb does not work

[benjdero]

HideWhileIdle seems to do nothing as the thumb always stay visible.

val listState: LazyListState = rememberLazyListState()
val state: ScrollAreaState = rememberScrollAreaState(listState)
ScrollArea(
    overscrollEffect = null,
    state = state
) {
    LazyColumn(
        modifier = modifier.then(
            Modifier.fillMaxHeight()
        ),
        state = listState
    ) {
        items(itemList) { item: Item ->
            ItemView(
                item = item,
                onItemClick = onItemClick
            )
        }
    }
    VerticalScrollbar(
        modifier = Modifier
            .align(Alignment.TopEnd)
            .fillMaxHeight()
            .width(6.dp)
    ) {
        Thumb(
            modifier = Modifier.background(Color.LightGray),
            thumbVisibility = ThumbVisibility.HideWhileIdle(
                enter = fadeIn(),
                exit = fadeOut(),
                hideDelay = 0.5.seconds
            )
        )
    }
}

The problem seems to be there:

compose-unstyled/core/src/commonMain/kotlin/ScrollArea.kt

Line 361 in f834d25

delay(thumbVisibility.hideDelay)

If the user is still scrolling when the delay end (because he never stopped scrolling, or because he stopped but started scrolling again). Then the scrollbar will never disappear.

Should be rather straightforward to fix. If you feel like contributing, go for it

Is it? What pattern would you use to restart the delay? Le lun. 7 oct. 2024, 15:48, Alex Styl ***@***.***> a écrit :
