How to get just the filename from full file path?

[DiamonDogX]

If I have a file path like C:/temp/foo.txt, is there a convenient, proper, cross-platform way to extract just the "foo.txt" part? Thx.

QFileInfo::fileName()

and with QString you can use QString::lastIndexOf(), QString::rightJustified() and QString::size()
