由于我是QT新手，所以有一些示例会更好，以便更好地理解它.似乎有三种不同的方式?最好的是什么?是否使用QAbstractItemView?

As I'm new in QT it would be nice to have some example, to understand it better. And as it seems there are three different Ways? What will be the best? Do use a QAbstractItemView?

推荐答案

是.您需要使用:

QAbstractItemView::setIndexWidget ( const QModelIndex & index, QWidget * widget )

QListView继承了QAbstractItemView，并且当您尝试自定义列表/树视图时，通常这是查看的地方.但是要小心，没有代表，这将无法很好地扩展.看看这个线程: http://www.qtcentre.org/线程/26916-insertting-custom-Widget-to-listview

QListView inherits QAbstractItemView and when you're trying to customize list/tree views that's usually the place to look. Be careful though, without a delegate this doesn't scale very well. Check out this thread: http://www.qtcentre.org/threads/26916-inserting-custom-Widget-to-listview
