Dois-je utiliser QThread ou autre ?

Bonsoir,

Je ne sais pas vraiment comment m' y prendre, en ajoutant ceci (cf processinfo.cpp) toute l' interface qml est ralentie. je fais un appel sur le return toutes les 2-3 secondes dans qml.

Le simple fait d' ajouter cela fait passer la consomation cpu de 0-1% à 2% constant.

QByteArray PROCESSInfo::processTOP()
{
 
    QProcess p(this);
 
    p.start("sh", QStringList() << "-c" << "top -b -n 1  | awk '{print $9, $10, $1, $12}' | head -n 16 | tail -n 10");
    if (!p.waitForFinished(1000))
        return QByteArray("error");
 
    QStringList list = QString::fromLatin1(p.readAllStandardOutput()).split("/n");
 
    QString result;
 
    foreach(QString s, list)  {
        result.append(s.split(" ").join(" - ")).append("\n");
    }
 
 
    return result.toLatin1();
}

Auriez vouz une idee de comment m' y prendre?

J' ai regardé du coté de QThread mais je m' y perd sur la facon d envoyer ca à qml.

Cordialement.
