I found the culprit but not a solution yet:
When generating the list of items in my pre-process, I already parent
them to each other for use in a QTreeView, e.g.:
cur_root_item.setChild(item_counter, cur_file_item)
Turns out I can't just show all items in a simple list ignoring their
parenting.
How would I go about this then if I need both a "flat" list for a report
print out and also tree view for the user to interact with, e.g.:
QListView would show (ignoring existing parenting):
* itemA
* itemB
* itemC
QTreeView of the same model would show (based on previous parenting):
itemA
|___itemB
|____itemC
Do I need two models and communicate between them (e.g. if a user
renames an item)?
Or can this be achieved with a single model?
Thanks,
frank

Hi,
I seem to run into this issue a lot and I don't get why:
I have a list of sub-classed QStandardItems that another processor
generated, and I want to add them to a QStandardItemModel like this:
for item in myItemList:
self.model.appendRow(item)
The model is empty and hasn't been used at this point. Yet I get none
of my items but one of those errors for each item:
QStandardItem::insertRows: Ignoring duplicate insertion of item
I know I should know this but I can't figure out why this is
happening. Is there something special I need to do when subclassing
QStandardItem?
Cheers,
frank
