QT：把Qstring类型的"0x4f00"转成int 类型的0x4f00

QT：把Qstring类型的"4f00"转成int 类型的4f00

QString hexstr = hexlist.at(i);
        QString x = "0x"+hexstr.left(4);
        QString y = "0x"+hexstr.right(4);
        bool ok;
        cx[i] = x.toInt(&ok,16);
        cy[i] = y.toInt(&ok,16);

strtol(const char , char *, int);

最简单的用 QByteArray.toUInt(Q_NULLPTR,16);
不过先要把0x去掉
