[Qt-interest] QFileSystemModel and QTreeView interesting problemH

[Denis Akhmetzyanov]

Or if you wish to make QDir::homePath() the root of the tree view you could
use:

    QModelIndex index = treeModel->setRootPath(QDir::homePath());
    treeView->setRootIndex(index);
    // or
    treeView->setRootIndex(treeModel->index(QDir::homePath()));
