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.

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.
