QSerialPortInfo Class

  • Header: QSerialPortInfo

  • Since: Qt 5.1

  • CMake:

    find_package(Qt6 REQUIRED COMPONENTS SerialPort)

    target_link_libraries(mytarget PRIVATE Qt6::SerialPort)

  • qmake: QT += serialport

  • Group: QSerialPortInfo is part of serialport-main

Detailed Description

Use the static functions to generate a list of QSerialPortInfo objects. Each QSerialPortInfo object in the list represents a single serial port and can be queried for the port name, system location, description, and manufacturer. The QSerialPortInfo class can also be used as an input parameter for the setPort() method of the QSerialPort class.

Member Function Documentation

 

QSerialPortInfo::QSerialPortInfo()

Constructs an empty QSerialPortInfo object.

See Also

See also isNull()

[explicit] QSerialPortInfo::QSerialPortInfo(const QSerialPort &port)

Constructs a QSerialPortInfo object from serial port.

[explicit] QSerialPortInfo::QSerialPortInfo(const QString &name)

Constructs a QSerialPortInfo object from serial port name.

This constructor finds the relevant serial port among the available ones according to the port name name, and constructs the serial port info instance for that port.

QSerialPortInfo::QSerialPortInfo(const QSerialPortInfo &other)

Constructs a copy of other.

QSerialPortInfo::~QSerialPortInfo()

Destroys the QSerialPortInfo object. References to the values in the object become invalid.

[static] QList<QSerialPortInfo> QSerialPortInfo::availablePorts()

Returns a list of available serial ports on the system.

QString QSerialPortInfo::description() const

Returns the description string of the serial port, if available; otherwise returns an empty string.

See Also

See also manufacturer(), serialNumber()

bool QSerialPortInfo::hasProductIdentifier() const

Returns true if there is a valid 16-bit product number present; otherwise returns false.

See Also

bool QSerialPortInfo::hasVendorIdentifier() const

Returns true if there is a valid 16-bit vendor number present; otherwise returns false.

See Also

bool QSerialPortInfo::isNull() const

Returns whether this QSerialPortInfo object holds a serial port definition.

QString QSerialPortInfo::manufacturer() const

Returns the manufacturer string of the serial port, if available; otherwise returns an empty string.

See Also

See also description(), serialNumber()

QString QSerialPortInfo::portName() const

Returns the name of the serial port.

See Also

See also systemLocation()

quint16 QSerialPortInfo::productIdentifier() const

Returns the 16-bit product number for the serial port, if available; otherwise returns zero.

See Also

[since 5.3] QString QSerialPortInfo::serialNumber() const

Returns the serial number string of the serial port, if available; otherwise returns an empty string.

The serial number may include letters.

This function was introduced in Qt 5.3.

[static] QList<qint32> QSerialPortInfo::standardBaudRates()

Returns a list of available standard baud rates supported by the target platform.

void QSerialPortInfo::swap(QSerialPortInfo &other)

Swaps QSerialPortInfo other with this QSerialPortInfo. This operation is very fast and never fails.

QString QSerialPortInfo::systemLocation() const

Returns the system location of the serial port.

See Also

See also portName()

quint16 QSerialPortInfo::vendorIdentifier() const

Returns the 16-bit vendor number for the serial port, if available; otherwise returns zero.

QSerialPortInfo &QSerialPortInfo::operator=(const QSerialPortInfo &other)

Sets the QSerialPortInfo object to be equal to other.
