Group or Set widget (image provided)

Hi

I would like to create a "group or set" widget, which will allow a user to group/ungroup layers as seen in the attached picture.

I have done the layers using a custom tableview (in a test project), but I'm not sure how to do the grouping widget.

Could somebody guide me as to how grouping/ungrouping can be achieved?

Many thanks

I would go for a tree model. To group items make them children of an item.

Haha, it's funny, I completely forgot about tree containers!
QTreeWidget is exactly what I needed :-)
Thank you very much Lykurg.

It's solved.
