PyQt4: How do you iterate all items in a QListWidget

Question

Currently, I use the following while loop in a class that inherits QtGui.QListWidget to iterate all items:

    i = 0     while i < self.count():         item = self.item(i)          i += 1 

I was hoping I could use:

for item in self.items(): 

but the items() method wants a QMimeData object which I don't know how to construct to return all items. Is there a cleaner approach than my while loop above?
