by definition, there can only be one root item and that is already 
provided by the treewidget.

something like this might do what you want:

myroot = QTreeWidgetItem(mytreewidget)
mytreewidget.setRootIndex(mytreewidget.indexFromItem(myroot))

but note that that wont actually replace the invisible root item - it 
just creates a hidden top level item that can be used as the parent of 
all subsequent items.

(as usual, it would be a lot easier to help if you told us what problem 
you are actually trying to solve...)
