[Qt-interest] Process_line

[Donal O'Connor]

Process line is just an example of a method you might declare to "process"
the line.

This is a user defined method but it doesn't have to be a method, you can do
what ever you want to the line operating on the line QByteArray, for
example, convert to a QString and do splitting or something....
