The QMqttMessageStatusProperties class represents additional information provided by the server during message delivery. More...
|qmake:||QT += mqtt|
This class was introduced in Qt 5.12.
Depending on the QoS level of a message being sent by QMqttClient::publish(), a server reports the state of delivery. Additionally to the QMqtt::MessageStatus, complementary information might be included by the server. These are exposed to users via QMqttMessageStatusProperties.
Note: Message status properties are part of the MQTT 5.0 specification and cannot be used when connecting with a lower protocol level. See QMqttClient::ProtocolVersion for more information.
