[Interest] QML TableView creating extra row delegates

[deDietrich Gabriel]

Hi,


Yes, it's normal when alternatingRowColors is true, which it is by default. That is so that it doesn't look like the table is truncated when there's not enough rows to fill the table height. Just set alternatingRowColors to false and it should go away. (If you still need the feature, test for styleData.rowIndex % 2 in your row delegate.)

Subject: [Interest] QML TableView creating extra row delegates

Hi list,

I noticed that the QML TableView creates extra row delegates even if there are only a few items in the model. For example the following code-

TableView {
        anchors.fill: parent
        model: ListModel {
            ListElement { name: "Apple"; cost: 2.45 }
            ListElement { name: "Orange"; cost: 3.25 }
            ListElement { name: "Banana"; cost: 1.95 }
        }
        rowDelegate: Rectangle {
            height: 64; width: parent.width
            color: "red"; radius: 10
        }
        TableViewColumn {
            role: "name"; title: "Name"; width: 200
        }
    }

The TableView that this gives looks like http://i.imgur.com/h1f1Q3F.png (apologies for the red :P)

Is this expected behavior? If yes, how do I make sure not to handle interaction on the invalid rowDelegates?

Cheers,
