QNdefMessage#

The QNdefMessage class provides an NFC NDEF message. More

Functions#

Static functions#

Detailed Description#

A QNdefMessage is a collection of 0 or more QNdefRecords. QNdefMessage inherits from QList < QNdefRecord > and therefore the standard QList functions can be used to manipulate the NDEF records in the message.

NDEF messages can be parsed from a byte array conforming to the NFC Data Exchange Format technical specification by using the fromByteArray() static function. Conversely QNdefMessages can be converted into a byte array with the toByteArray() function.

Parameters

Constructs a new empty NDEF message.

static PySide6.QtNfc.QNdefMessage.fromByteArray(message)#
Parameters

messagePySide6.QtCore.QByteArray

Return type

PySide6.QtNfc.QNdefMessage

Returns an NDEF message parsed from the contents of message.

The message parameter is interpreted as the raw message format defined in the NFC Data Exchange Format technical specification.

If a parse error occurs an empty NDEF message is returned.

Return type

bool

Returns true if this NDEF message is equivalent to other; otherwise returns false.

An empty message (i.e. isEmpty() returns true) is equivalent to a NDEF message containing a single record of type Empty .
