前言
QListWidget类提供了一个基于项目的列表小部件 QListWidget是一个方便的类，它提供了一个列表视图，类似于QListView提供的列表视图，但是具有一个用于添加和删除项的经典基于项的接口。QListWidget使用一个内部模型来管理列表中的每个QListWidgetItem。要获得更灵活的列表视图小部件，请使用带有标准模型的QListView类。列表小部件的构造方法与其他小部件相同。QListWidget与QListView类似，都可以显示一列Item，区别在于前者可以往其中增删Item。 QListWidget确定可以同时选择列表中的多少项，以及是否可以创建复杂的项选择。这可以使用函数设置
一、QListWidget 和 QListView 的差异
QListWidget 是一个更新且更高级的元件，能够更为方便地进行开发，例如 QListWidget 具有 QStantandardItemModel 无法访问的类型，也能更轻鬆的透过 QListWidgetItem 处理数据，然而如果使用 QListView，许多方法必须要额外定义，属于比较旧的使用方式。
QListView、QListWidget是列表形式展示的控件。
QTableView、QTableWidget是表格形式展示控件。
继承关系：带Widget的继承自View，即：QListWidget是继承QListView，QTableWidget继承自QTableView。
区别：QListView是基于Model，而QListWidget基于Item。这是它们的本质区别。QTableView、QTableWidget同理。
由于QListView和QTableView是基于model的，需要自己来建模（例如建立QStringListModel、QSqlTableModel等），保存数据，这样就大大降低了数据冗余，提高了程序的效率，以及能更方便的进行我们自己需要展示的内容，但是需要我们对数据建模有一定了解。
而QListWidget相当于是QListView的升级版，它已经自己为我们建立了一个数据存储模型（QListWidgetItem），操作方便，直接调用addItem即可添加项目（ICON，文字）。QTableView、QTableWidget同理。
