    Default Looking for an alternative to ListView's itemAtIndex

    As I'm using Qt 5.12, I can't use itemAtIndex which is available since Qt 5.13.
    I can't upgrade my Qt version as I have project/platform restrictions. In this regard, please suggest any alternative that gives similar functionality as itemAtIndex.

    Thank you.

    Hi, how do you get the index for itemAtIndex()?
    Could you show us some code where you would like to use itemAtIndex() if you could?

    Thanks for the reply.
    I have a ListView & it's delegate. I get the index in the delegate's MouseArea. Here is the code snippet of the delegate for your perusal.

    Qt Code:
    1. Component {
    2. id: cateListDelegate
    3. Rectangle {
    4. id: drawer
    5. width: root.itemWidth
    6. height: cateList.height
    7. radius: 6
    8. color: "#e69400"
    9.  
    10. TextSrc {
    11. font.pixelSize: sizeInPixel
    12. color: "white"
    13. anchors.left: parent.left
    14. anchors.leftMargin: 4
    15. anchors.right: parent.right
    16. anchors.rightMargin: 4
    17. horizontalAlignment: Text.AlignHCenter
    18. wrapMode: Text.WrapAtWordBoundaryOrAnywhere
    19. maximumLineCount: 2
    20. anchors.verticalCenter: parent.verticalCenter
    21. text: title
    22. }
    23.  
    24. MouseArea {
    25. anchors.fill: drawer
    26.  
    27. onClicked: {
    28. console.log("Main category delegate clicked");
    29. MCategoryGrid.selectMain(index);
    30.  
    31. cursorPosition(idx) // --> Call a function passing index to get the item
    32.  
    33. isFocusOnMainlist = true
    34. }
    35. }
    36. }
    37. }
    38.  
    39. function cursorPosition(idx)
    40. {
    41. console.log("cateList.count: ", cateList.count);
    42. console.log("cursorPosition2::index - ", idx);
    43. let item = cateList.itemAtIndex(idx);
    44.  
    45. if (item) {
    46. mainCcursor.x = item.x + (mainCcursor.width/2)
    47. mainCcursor.y = item.y;
    48. }
    49. }
    To copy to clipboard, switch view to plain text mode 

    I have mentioned in the code comment the place where I intend to call the function by passing index to get the item.
