Detailed Description
SetLoggerLevelsServiceClient calls a ROS 2 service. Set the topic and node properties, then call callService() to invoke the service. Alternatively, bind the request property: whenever the bound value changes, the service is called automatically and response is updated with the result.
Property Documentation
request : QList<Qtros2RclInterfacesMsgs::LoggerLevel>
The request value for declarative service calls. When autoCall is true (the default), each change of this property schedules a service call at the end of the current event-loop iteration; changes made while the service is unavailable or a call is in flight are remembered and the latest value is dispatched as soon as possible. The result arrives in response.
response : QList<Qtros2RclInterfacesMsgs::SetLoggerLevelsResult>
The most recent response received from the service, whether the call was made via request or callService(). Holds a default-constructed value until the first response arrives. Updated just before responseReceived is emitted.
Signal Documentation
callFailed(string error)
Emitted when the service call fails. error contains the error message.
Note: The corresponding handler is onCallFailed.
responseReceived(QList<Qtros2RclInterfacesMsgs::SetLoggerLevelsResult> response)
Emitted when the service call completes successfully. response is a QList<Qtros2RclInterfacesMsgs::SetLoggerLevelsResult> value.
Note: The corresponding handler is onResponseReceived.
Method Documentation
QJSValue callService(const QList<Qtros2RclInterfacesMsgs::LoggerLevel>&request)
Calls the SetLoggerLevels ROS 2 service with QList<Qtros2RclInterfacesMsgs::LoggerLevel> request. Returns a JS promise that resolves with a QList<Qtros2RclInterfacesMsgs::SetLoggerLevelsResult> response or rejects with an error string. isServiceReady must be true before calling.
