qt 本地文件浏览程序

[ronal7do]

想用qt Model/View的QListView实现一个本地文件浏览，模型使用的是QFileSystemModel，但发现View显示的只是那一个路径的文件，而不能返回上一层或进入某个文件夹。我想实现如下图的效果：

点击最上面的../能返回上一层，点击文件夹能进入文件夹访问，请问大家，该用什么实现？

QModelIndex QFileSystemModel::setRootPath(const QString & newPath) Sets the directory that is being watched by the model to newPath by installing a file system watcher on it. Any changes to files and directories within this directory will be reflected in the model. If the path is changed, the rootPathChanged() signal will be emitted. Note: This function does not change the structure of the model or modify the data available to views. In other words, the "root" of the model is not changed to include only files and directories within the directory specified by newPath in the file system. 双击 或 单击 信号，后取当前 路径 设置 setRootPath
