QListView with Groups
-
I'd like to create a ListView with groups, ala .NET's ListView class. The end goal is something similar to Ubuntu's System Settings dialog, with a root item represented by header text, and the subset of items displayed by clickable icons.
I'm a bit confused by my options. QListView may not be appropriate, as it is designed to handle non-hierarchical lists. QTreeView, however, isn't quite right either, because I want the subitems to be displayed in an icon view.
Will this require just a custom QItemDelegate, or will I need to implement a new subclass of QAbstractItemView?

implementing a custom QAbstractItemView is overkill in almost all situations :)
A custom QItemDelegate may work, i am not sure if it will work with a QListView with setViewMode(QListView::IconMode).
I would suggest you compose a custom widget. With QLabels for the headlines and a QListView with icon-mode set for the sub-items.
You can then use stylesheets to hide the frame of the listview etc.
To have a single selection across all the list views will be a bit tricky but possible. -
I think I take your meaning. As I geared up to subclass QAbstractItemView, it also became evident how niche my new class would be. Based on this, I decided to take your advice of composing a custom widget.
If anyone should want to subclass QAbstractItemView, this is a good article to get you started.
