Select only item in TreeView

[Rutra]

Hi!

I have next TreeView in QML:

TreeView {
    id: tree
    width: 300
    model: pgItemModel
    headerVisible: false

    TableViewColumn {
        resizable: true
        role: "display"
    }
}

When user selects a tree item, entire row will be highlighted:

But better if only tree item will be highlighted, as in the following example:

How can I do this?
Thanks!
