我正在开发一个名为“配置管理器”的窗口，它允许用户：
ListViewTextEdit列表视图显示过滤/排序的项目。当用户单击列表视图的一项时，我会更改该项的颜色。如果他单击另一个项目，前一个项目的颜色会恢复为默认颜色，并且新项目的颜色也会发生变化。
数据存储在后端的一个继承自
QAsbtractListModelQSortFilterProxyModel列表视图最多可以显示 100 个元素，因此我添加了一个滚动条以便能够选择其上显示的任何委托。
如果我选择第一个项目，颜色会正常更新。如果我单击第一个项目旁边的另一个项目，这两个项目（前一个和新的）的颜色变化也可以。如果选择顶部的一个项目，滚动列表视图的底部并选择另一个项目，我会遇到问题。这样，前一项就不会更新，并且仍然具有所选的颜色。在后端，通过一些 qDebug，我可以确认上一个项目没有更新，因为 setData 方法没有像我选择一个项目时那样被调用（以更新 GUI 上的颜色和模型上该元素后端的布尔值） ).
我这里不是说用键盘的CTRL或SHIFT键进行多重选择，但问题是一样的。仅更新部分项目。
我认为我缺少列表视图的一些属性，因为似乎并非所有委托都在缓存中（因此在滚动并选择新项目时不会更新）。
我添加了下面的代码，我现在不能做得更短。预先感谢您的帮助。

感谢@JarMan的建议，我简化了QML部分，列表视图的委托上不再有算法部分。现在后端会自行更新我想要的模型上每个项目的角色
