    Default ListView indexAt,itemAt issue

    I have ListView and i use mouse coordinate check and get index, item from ListView. I use listView.indexAt(x,y), listView.itemAt(x,y), in normal ListView i get them successfully but in ListView i add verticalLayoutDirection: ListView.BottomToTop, listView.indexAt(x,y), listView.itemAt(x,y) can't get value.
    How i can get indexAt, itemAt correct?

    Qt Code:
    1. ListView {
    2. id:list
    3. anchors.fill: parent
    4. interactive: false
    5. verticalLayoutDirection: ListView.BottomToTop
    6. MouseArea {
    7. id:mous
    8. anchors.fill: parent
    9. onPositionChanged: {
    11. var positionInRoot = mapToItem(list, mouse.x, mouse.y)
    13. var index = list.indexAt(positionInRoot.x,positionInRoot.y) // is not correct when use verticalLayoutDirection: ListView.BottomToTop
    14. var item = list.itemAt(positionInRoot.x,positionInRoot.y) // is not correct when use verticalLayoutDirection: ListView.BottomToTop
    16. }
    17. }
    To copy to clipboard, switch view to plain text mode

    Default Re: ListView indexAt,itemAt issue

    Does using list.height-positionInRoot.y etc. yield proper indices? Why do you need that index value at all? If it is your actual code then MouseArea is the delegate for the view so it is enough to react to onEntered and onExited to store the "current" index on the view. If MouseArea is not your delegate then you can apply MouseArea to the delegate item and re-read the previous sentence of my post.
    Your biological and technological distinctiveness will be added to our own. Resistance is futile.
