    Default Display a subfolder from QDirModel with QTreeView

    My code below will display the whole file system. I just want to display a subfolder (ex D:\folder1), with all it's contents.
    I tried setting the root index of the treeView but this will hide the folder (only the contents of the folder1 will be shown).
    I also tried using "setFilterRegExp()" and "setFilterKeyColumn()", but this approach will also NOT work because it will filter the parents as well.
    I also tried subclassing the QSortFilterProxy" but that seems a little too much for what I'm trying to achieve.

    Is there an easier method here?

    Qt Code:
    1. int main(int argc, char *argv[])
    2. {
    3. QApplication a(argc, argv);
    4. QDirModel *model = new QDirModel();
    5. QSplitter *splitter = new QSplitter();
    6. QTreeView *leftTree = new QTreeView(splitter);
    7.  
    8. proxyModel->setSourceModel(model);
    9. leftTree->setModel(proxyModel);
    10.  
    11. splitter->show();
    12. return a.exec();
    13. }

    Probably you need to retrieve the QModelIndex for the folder you are interested in using QDirModel::index() and then set that as the root index on the tree view. I'm not sure what you hope to accomplish with a proxy model.

    That works, but it will only display the contents at that path(or children in the model), I want to have the folder too, like this:

    setRootIndex() will display:

    ---SubFolder1
    ---File1
    ---etc

    I want:

    -Folder1
    ---SubFolder1
    ---File1
    ---etc
