推荐答案

自Qt5.5开始，我们提供了 TreeView QML组件，

Since Qt5.5 we have TreeView QML component available,

main.qml :

import QtQuick.Controls 1.4 TreeView { anchors.fill: parent TableViewColumn { title: "Name" role: "fileName" width: 300 } model: my_model }

main.cpp :

QFileSystemModel model; model.setRootPath("/"); QQmlApplicationEngine engine; engine.rootContext()->setContextProperty("my_model", &model); engine.load(QUrl(QStringLiteral("qrc:/main.qml")));
