Look here: http://www.riverbankcomputing.co.uk/static/Docs/PyQt4/html/qprocess.html Here's a C++ snippet that needs very little modification in order to run as a PyQt program: The following example runs gzip to compress the string "Qt rocks!", without an event loop: QProcess gzip; gzip.start("gzip", QStringList() << "-c"); if (!gzip.waitForStarted()) return false; gzip.write("Qt rocks!"); gzip.closeWriteChannel(); if (!gzip.waitForFinished()) return false; QByteArray result = gzip.readAll(); _______________________________________________ PyQt mailing list [email protected] http://www.riverbankcomputing.com/mailman/listinfo/pyqt
