I'm now stumbling over this little problem: how do I convince a
QTreeView/QFileSystemModel to display the contents of a particular
subdirectory only ?

QFileSystemModel::setRootPath() doesn't do this, though it does return
a QModelIndex, which I've tried using in the view as the root index, like
so:

    dir_model_ = new QFileSystemModel(this);
    QModelIndex root_index = dir_model_->setRootPath(<some path>);

    files_tree->setModel(dir_model_);
    files_tree->setRootIndex(root_index);

When I try this, the view displays nothing at all - I don't know why.

Any suggestions ?
