Qt中的QListWidget可以实现一个列表,比如网页上经常出现的下拉列表框,其中一行就是一个ListItem,在添加时,常用的函数是QListWidget::addItem(QListWidgetItem * item),但这样只能添加QListWidgetItem这样的对象,如果想到像QQ等软件使用自定义的ListItem,一个简单的方法是自定义一个QWidget,然后使用QListWidget::setItemWidget(QListWidgetItem * item, QWidget * widget)来设置它的显示widget.
首先,自定义了一个QWidget,作为QListWidgetItem的子元素,所有的布局都在这个widget中完成,它便是后来显示的每个小条目.
首先,添加一个QListWidgetItem,然后为其设置Widget为我们自定义的Widget:

不错 学习了
谢谢分享，找了好久才找到这个例子
ui->listWidget->setItemWidget(listItem1, custom1); 这句代码报错，显示无法从“const QString”转换为“QListWidgetItem
非常有用的帖子！！！感谢
listItem1 因该是QListWidgetItem类型的，你可能类型创建错误了
精简，直接，了得，非常好！ 非常感谢！ 本来一直想用QListView来着，没有找到自定义item的，后面找到这个，哈哈这个才是我要的！！！[color: Red][/color]
问下，如果要动态修改咋办？ 比如里面的第二项里面的 text2 我要修改成 你好 难道是先删除这一整个项，然后插入一个新的？
修改你自定义的那个 widget 的数据就可以了呀
如何移除这个自定义控件呢？
直接 remove，QListWidget会帮你删除的，不过你在外面不能在持有对象的指针了，不然就。。。
博主 你好, 我在使用 QListWidget 的时候遇到一些问题: 首先我使用的是 mac 下的 qt 开发环境, 使用自定义的 item 时, 选中不会高亮了, itemEntered的判定区域也是不对的, 最主要的是 自定义的 widget 的效果(背景色效果)都无法显示出来. 请问一下, 这个是什么问题, 是QListWidget在 mac 环境下不支持的问题吗?
博主，我要怎么给列表添加第二项，按这个我添加了表单的一个小项目但是不能additem第二行
可以水平添加吗？
