But I am looking for a method where I don't have to separate the base 
folder. I want to accept user input like "/usr/bin/*" and list those 
files, but I haven't found a way to provide this path directly to Qt. It 
looks like I need to split off the path first.

QDirIterator behaves the same as QDir, which I tried originally as I 
wrote above. Here it is tested in Python:

 >>> from PyQt5 import QtCore
 >>> di=QtCore.QDirIterator("/", ["/usr/bin/*"])
 >>> di.next()

On a related note, where is the equivalent of os.path.join()?
