Now on to figure out how to display checkboxes next to each item. I've tried:
Qt::ItemFlags ImportDataStructureModel::flags(const QModelIndex& index) const
{
if(!index.isValid())
{
return {};
}
return Qt::ItemIsUserCheckable | Qt::ItemIsSelectable |
QAbstractItemModel::flags(index);
}
Which does not seem to show anything. I'll probably have to create a custom
delegate.

Hi Mike,
If you return flag ItemIsUserCheckable in your model, then you must also
return a valid variant with Qt::CheckState for data(Qt::CheckStateRole)
- it won't just assume Qt::Unchecked.
Ditto with the item widgets - besides item->setFlags, you need to call
item->setCheckState as well.
