It should work, but it's blocking (which is not nice)... you should make use 
of QProcess's asnychronous operation.

Use QProcess::readAllStandardOutput() to read from the process's stdout 
channel:
http://qt-project.org/doc/qt-4.8/qprocess.html#readAllStandardOutput

Use QProcess::readAllStandardError() to read from stderr:
http://qt-project.org/doc/qt-4.8/qprocess.html#readAllStandardError
