GridVIew last item auto selected on insert

[nminkov]

Hi,
I am struggling with simple issue . Every time I insert an item in my GridView, the last inserted item is selected. That is, last inserted item automatically becomes currentItem/currentIndex.

How can I avoid that?

Hi @nminkov , i guess you must be handling some focus stuffs in the gridview, by default there is no auto select or auto highlight feature in GridView, it would be better if you would post your sample code.

Here is a sample code please have a look into it:-

ListModel {
id: dummyModel

    ListElement {
        name: 0
    }
    ListElement {
        name: 1
    }
    ListElement {
        name: 2
    }
    ListElement {
        name: 3
    }
}

GridView {
    id: gridView

    width: parent.width;
    height: 200

    model: dummyModel
    delegate: Rectangle {
        width: 100
        height: 100
        color: "cyan"
        border.color: GridView.isCurrentItem ? "red" : "black"
        border.width: 4

        Text {
            anchors.centerIn: parent
            text: name
        }

        MouseArea {
            anchors.fill: parent
            onClicked: {
                gridView.currentIndex = index
            }
        }
    }
}

Button {
   text: "Add Item"
   anchors.centerIn: parent
   onClicked: {
       dummyModel.append({"name": dummyModel.count})
   }
}

Sample Output:-

Note:- Highlighted Rectangle will have a red border, on clicking the Rectangle iam changing the current index of the gridview and on clicking on add item iam inserting a item into the model.

@Shrinidhi-Upadhyaya Thanks for the complete answer. It helped me track the issue to the insert function.

In my model, I was using beginInsertRows(QModelIndex(), 0, 0), which inserted rows in front instead of back. It was unintended and caused to display the wrong text under every element. That made me believe the actual selected element was wrong.
