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.

Code:

---

Component {
        id: cateListDelegate
        Rectangle {
            id: drawer
            width: root.itemWidth
            height: cateList.height
            radius: 6
            color: "#e69400"
 
            TextSrc {
                font.pixelSize: sizeInPixel
                color: "white"
                anchors.left: parent.left
                anchors.leftMargin: 4
                anchors.right: parent.right
                anchors.rightMargin: 4
                horizontalAlignment: Text.AlignHCenter
                wrapMode: Text.WrapAtWordBoundaryOrAnywhere
                maximumLineCount: 2
                anchors.verticalCenter: parent.verticalCenter
                text: title
            }
 
            MouseArea {
                anchors.fill: drawer
 
                onClicked: {
                    console.log("Main category delegate clicked");
                    MCategoryGrid.selectMain(index);
 
                    cursorPosition(idx)  // --> Call a function passing index to get the item
 
                    isFocusOnMainlist = true
                }
            }
        }
    }
 
    function cursorPosition(idx)
    {
        console.log("cateList.count: ", cateList.count);
        console.log("cursorPosition2::index - ", idx);
        let item = cateList.itemAtIndex(idx);
 
        if (item) {
            mainCcursor.x = item.x + (mainCcursor.width/2)
            mainCcursor.y = item.y;
        }
    }

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