    Angry How to create root node inQDirModel

    Hello all,
    I want to create the tree representation of the selected directory in my file system. Currently below code is used for this:

    QDirModel model;
    model.setFilter(QDir:irs | QDir::Files);
    QTreeView tree_view;
    tree_view.setModel(&model);
    tree_view.setRootIndex(model.index("c:\myFiles"));
    tree_view.show();

    But problem with this code is that, it is not showing the selected directory as a root node. Instead, it only shows the files (and directories) presented in c:\myFiles directory. i.e. i want to view my tree structure as below

    myFiles
    │-- A.vbs
    │-- B.log
    │-- C.log
    │
    └───Test
    │-- Y.log
    â””-- X.vbs


    But i am getting the below populated structure (without root element).

    -- A.vbs
    -- B.log
    -- C.log
    └───Test
    │-- Y.log
    â””-- X.vbs

    Also i want to create tree structure of two independent folders in a single tree view in the later course of actions.
    Kindly help.

    Hi, does the root node show up when you don't set filters?
    And maybe you want to use QFileSystemModel, because its performance is better than QDirModel.
