Qt 执行CMD命令

static void runCmdTools(const QString& cmd){    QProcess p;    p.start("cmd", QStringList() << "/c" << cmd);//p.startDetached("cmd", QStringList() << "/c" << cmd)    p.waitForFinished();    p.close();}


读取执行CMD返回的值
static QString readCmdContent(const QString& cmd){    QProcess p;    p.start（cmd）);    if(!p.waitForFinished())        return NULL;    QString tmp;    QString info = tmp.prepend(p.readAll());    p.close();    return info;}
