An example for the TreeView 控件。
警告： 从 Qt 5.12 起弃用 Qt Quick Controls 1 模块。使用最新 Qt Quick Controls 模块代替。
This example project demonstrates the usage of TreeView from Qt Quick Controls 1 - a control to display a tree representation of items from a model derived from the QAbstractItemModel 类。
The example displays the home path data given by the QFileSystemModel model.
