Dynamic Gridview Cellwidth and CellHeight

[admiral142]

I'm using a GridView to display some rectangles. In the event that the number of icons I have is odd, I want to stretch the rectangles in the bottom row to fill that bottom row. I've been able to set the rectangles correctly, but the GridView cellWidth is proving difficult to change. Is there a way to set the GridView cellWidth differently based on the row that you're on? Something like:

GridView{
        model: menuList
        delegate: menuItemDelegate
        cellHeight: parent.height / rows
        cellWidth: {
            //bottomColsFill is TRUE when there is an odd number of items in the menuList
            if(bottomColsFill && index > (menuList.length - cols)){
                return parent.width / (cols - 1);
            }
            else{
                parent.width / cols;
            }
        }// previous code parent.width / cols
    }
