On related note, check threadutil.py / async_syscmd. It uses QProcess and
gives callback when command has been completed (avoiding threads completely
due to Qt even loop integration)
def async_syscmd(cmd, onfinished):
proc = QtCore.QProcess()
def cmd_handler(exitstatus):
out = proc.readAllStandardOutput()
err = proc.readAllStandardError()
#print "got",out, "e", err, "r", exitstatus
onfinished(exitstatus, out, err)
proc.finished[int].connect(cmd_handler)
proc.start(cmd)
#garbage.append(proc)
