[Qt-interest] QTreeWidgetItemIterator weird behaviour

[NARCISO, Rui]

I had read in the doc and I understand the order parent-> child.
The question is, what is the order on all of the children of a given parent ....

I'm not completely sure about the order it uses to iterate over top-level 
items, but the docs state the following, which basically means that it 
traverses the tree:

"The iterator will walk the items in a pre-order traversal order, thus 
visiting the parent node before it continues to the child nodes."
(http://qt.nokia.com/doc/4.5/qtreewidgetitemiterator.html#details)

So the question is, what does "pre-order traversal order" exactly mean?
