[PyQt] deleting QTreeWidgetItem

[Michael Towers]

Hi all,

Could someone confirm (or otherwise!) my understanding of the way PyQt4 
deals with management of Qt objects? If I want to delete a 
QTreeWidgetItem and all its children from a tree (and release all 
connected storage), is it enough to do the following?

         p = item.parent()
         p.removeChild(item)
	item = None

(assuming item is the only python reference to the QTreeWidgetItem).

Regards,
mt
