QObject::connect: Cannot queue arguments of type 'QSerialPort::SerialPortError'
(Make sure 'QSerialPort::SerialPortError' is registered using qRegisterMetaType().)
源代码如下:
connect(serial, SIGNAL(errorOccurred(QSerialPort::SerialPortError)),
this, SLOT(deal_with_error(QSerialPort::SerialPortError)), Qt::QueuedConnection);

在源代码前加入如下一句:
qRegisterMetaType<QSerialPort::SerialPortError>("SerialThread");
问题解决.
