QT quick TreeView and TreeViewStyle

[Pieter Cardoen]

I am trying to create a tree view using QT quick controls 1.4. I currently have this result:

I however have problems getting the layout in a decent way. I am using TreeViewStyle with a custom branch delegate which should include an icon. On the image, I used just a green circle to indicate the icon position. I note that the branch delegate is shifted to the left side and partially hidden.

I could fix this by increasing the indentation but that's not what I like. Is there any possible way to specify an offset for the indentation?

style: TreeViewStyle {
alternateBackgroundColor : "lightgray"
branchDelegate: Rectangle {
width: treeview.rowHeight * 2 + treeview.indent;
height: treeview.rowHeight
color: "transparent"

    CustomBranchDelegate{
        id: bd
        width: parent.height
        height: parent.height
        anchors.right: icon.left
        anchors.top: parent.top
        expanded: styleData.isExpanded
        hasChildren: styleData.hasChildren
        iconheight: 40
        color: "transparent"
    }
    Rectangle{
        id: icon
        anchors.right : parent.right
        anchors.top: parent.top
        radius: height / 2
        width: parent.height
        height: parent.height
        color: "green"
    }
}
rowDelegate : Rectangle{
    anchors {left: parent.left; right: parent.right; }
    color: styleData.alternate  ? "transparent" : "lightgray"
    height: treeview.rowHeight
}

indentation: treeview.indent

}

Thanks
