[qxoz]

Hi!
In database i have a data which are belongs to different groups. And i want display them as in a image below:

Rows are sorted in groups. I have few suggestions about how to realise it:

1. Use TreeView
2. Some list or tree with tableview in items
3. TableView with setSpan().

How it should be done in right way?
Thanks for advance.

Here are two more alternatives:
4. Use a more advanced data grid, like "qicsTable":http://www.ics.com/products/qt/qicstable/ or "QTitanDataGrid":http://www.devmachines.com/qtitandatagrid-overview.html
5. Use QML, which supports grouping (but as of yet, no tables).

There are many approaches, and I would not call the one better than the other for all cases. I'd probably avoid option 2 though, that looks like it could get messy rather soon.

If you are willing to shell out a bit of cash for a more powerful component, then that can be worth doing. Otherwise, I think going for a tree instead would be my first choice. You can style the root items to look like group headers easily. Qxt has a "delegate":http://libqxt.bitbucket.org/doc/0.6/qxtitemdelegate.html that can help you do this, but it is not that hard to do yourself either.

Thank you Andre!
QTitanDataGrid is a very good component but it's little bit expensive for my goals.
I think Tree is a good choice. Is QTreeView has an option which makes all items expanded?

Yes, it does. There are several expansion related slots available. Try the documentation...
