\class QNearFieldShareManager
\brief The QNearFieldShareManager class manages all interactions related to sharing files and data over NFC.
\ingroup connectivity-nfc
\inmodule QtNfc
\since 5.3
Applications can share NDEF data or file content using NFC technology by tapping two NFC-enabled devices
together. The QNearFieldShareManager provides a high level entry point to access this functionality.
The class allows both NDEF data and/or files to be shared between two devices by calling the setShareModes()
method. This method specifies either an NDEF Data and/or a File transfer. The targetDetected() signal is emitted
each time a share target is detected. A QNearFieldShareTarget pointer is passed with the signal, which can
be used to share either an NDEF message or one or more files.
The process of sharing files via NFC involves other underlying communication transports such as Bluetooth or Wi-Fi Direct.
It is implementation specific how and what type of transports are used to perform file transfer. The overall time taken to
transfer content depends on the maximum speed of the transport used. Note that the process of sharing NDEF message/data
does not require the use of other transports outside NFC.
If an error occurs, shareError() returns the error type.
Platforms that do not support both NDEF data and file content sharing modes can return the supported subset in the
supportedShareModes() method. Applications that call setShareModes() with an unsupported mode will receive an error
signal with a UnsupportedShareModeError.
Since sharing data over NFC is effectively a data pipe between two processes (one on the sender and one of
the receiver), the application developer should only create a single instance of QNearFieldShareManager per
application. This avoids the possibility that different parts of the same application attempt to all consume
data transferred over NFC.
