Detailed Description▲
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.
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.
