    Default Tree model - Proxy model that wrapped original model under a single parent node

    i am trying to create a proxy model using a read-only model that will have all the item in the R/O model under a single tree parent node. What function do I need to overwrite to make this happened? Do I derived from QAbstractItemModel or QAbstractProxyModel?

    Example:
    Original model
    * A
    ** x y
    * B
    * C
    ** x y

    Proxy Model (what I want)
    * Name-String
    ** A
    *** x y
    ** B
    ** C
    *** x y

    As you want to implement proxy model you should derive from QAbstractProxyModel

    What function do I need to overwrite to make this happened?
    Implement mapFromSource(), mapToSource(), columnCount(), rowCount(), index(), parent(), and data()
    When you know how to do it then you may do it wrong.
    When you don't know how to do it then it is not that you may do it wrong but you may not do it right.
