Analog os.walk in PyQt

Before I can continue implementing the dir / file recursive search with some filtering for some tasks, I want to know if Qt / PyQt has an analogue os.walk.

Main application - a graphical application in PyQt4, and all text fields in objects QStringand paths (files, directories) are used QFile, QDir, QFileinfofor manipulation.

By analogy, I mean the fast and convenient recursive tool to traverse the fs tree.

Should I use os.walkor something much faster and more informative?

PS. Maybe this one can help me, but I'm not sure if this is more effective than that os.walk.
