Use QStandardItemModel with QTreeView
-
https://doc.qt.io/qt-5/qstandarditemmodel.html#details - there is a short example on how to build a tree, so yes it's possible to use it in a QTreeView.
See also https://doc.qt.io/qt-5/qstandarditem.html#appendRow and https://doc.qt.io/qt-5/qstandarditem.html#appendRow-1 -

There's a complete example linked in that documentation.

@Alexey-Serebryakov In which case? There a tree is build up exactly what you requested. There is also a link to a more complete example below: https://doc.qt.io/qt-5/qtwidgets-itemviews-simpletreemodel-example.html

@Christian-Ehrlicher so bad and old example... Also I cant find a good simple example for my task.

Googling forQStandardItemModel QTreeViewcomes up with a number of other hits, have you looked through them to see if one fits you better -

Sorry but this example is exactly what you want, it doesn't matter when the code was written. You're just to lazy to try to understand it.

@Christian-Ehrlicher Hmm... I'm sorry but I already ask this forum. May be you can explain me.
I have already some tree structured data storage something like QMap<QString, QList<QString>> where key of map is parent items and values of map is children. How can I implement my model to view in QTreeView? May be I need to use QAbstractItemModel?That is very simple data storage but I cant find an any good example ot tutorials, in Qt Examples too.
Thanks a lot.

If you useQStandardItemModel/QStandardItems you will be copying your data items into the model. If you already have your own data structures,QAbstractItemModelcan be used to supply an interface to your existing data. -

I agree with Alexey that the example is incomplete. I am fumbling with setupModelData() and how to connect the model to a QTreeView. The example would be better if code for those two points were included.
