Sélectionnez
QFileSystemModel model;
model.setRootPath("");
if (parser.isSet(dontUseCustomDirectoryIconsOption))
model.iconProvider()->setOptions(QFileIconProvider::DontUseCustomDirectoryIcons);
QTreeView tree;
tree.setModel(&model);Declares model as data model for reading the local filesystem. model.setRootPath("") sets the current folder as the folder from which model will start reading. https:// object tree visualizes the filesystem in a tree structure.

const QSize availableSize = QApplication::desktop()->availableGeometry(&tree).size();
tree.resize(availableSize / 2);
tree.setColumnWidth(0, tree.width() / 3);
tree.setWindowTitle(QObject::tr("Dir View"));Sets layout options for animation, indentation, sorting, and sizing of the filesystem tree.
