[PyQt] Tree View QFileDialog?

[Brent Villalobos]

Perhaps I'm missing this, but is there a way to get a directory chooser 
dialog that shows the directories in a tree view?  I've been using 
"QtGui.QFileDialog.getExistingDirectory" as a directory-only selector, 
but I don't have an option to show the directories in a tree view.  I 
know I've used applications that show directories in a tree (where you 
can expand/contract nodes) and I was just wondering if Qt supports it 
out of the box as well and I'm just not seeing it.
