QTreeview - check if selected item is part of selected parent?
-
Hey
Does QT offer any out of box check if selected item is part of selected tree?
Say I have
-----Parent_A < Selected
----------Child_B
---------------ChildOfChild_C < Selected
---------------ChildOfChild_DWhen I do selectedIndexes() > I'll get 2 entries, how can I then check if the items are in treeSelection? Like I would need to get only Parent_A in my QList and remove ChildOfChild_C.
I reckon I need to do recursive function for it, but maybe QT offers something out of box?
Thanks!

I never saw any function to tell you that directly and did recursive
traverse the tree to find parent(s). -

traverse the tree to find parent(s).Mmm darn, I thought there was a function for it as that's what drag&drop has to check when dropping items. QT produces the correct result so perhaps there is a different way of doing it, mmmm will keep looking. Thanks!

Yeah maybe it would be interesting to inspect the code for
drop and see what it calls.That said, i have not used Views that much so there is still hope such function exists but just named something that dont spring to eye. :)

Yeah, I looked into it buts it's black magic. They use bits& other stuff which I struggle to understand... I think it happens in mimeData and decodeData(or other function that sound similar) No idea. Black magic :- )

Hi,
AFAIK, @mrjj is right, there's not direct way to get that information from the QItemSelectionModel as it might contain selection information from several views. You could maybe use QModelIndex::sibling to search for that information.
