ListView
ListView 是一个基本实现,提供了绘制 items 列表的功能。继承 BoxView。 ListView<T> 是其 item 的类型,可以接收任何对象。item 中的进一步处理在 CellFactory 中进行。为方便起见,它支持显示选中状态的通用较高层列表功能,如 check 和 radio 类型。基本上,您可以拥有一个项目列表,这些项目可以原样显示、显示其中任何项目具有选中状态或只有一个项目具有选中状态。

Customisation
具体如何显示各个单元取决于 CellFactory。默认实现只是使用 toString()
方法显示 item。
可以通过修改已使用的 CellFactory 进行自定义。
