Not really. Qt doesn't do such things like using QProcess to access some other executable to do some job, then parse all possible kinds of output and return the result to the user. Besides, at least on some Linux distros ping requires you to have superuser access rights as well.

I would be more interested in seeing proper support for serial devices in Qt rather than a wrapper around ping. Which is completely unreliable as a method to check if you have a working network connection, by the way.
