Detailed Description

GetPlanServiceClient 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 : getPlanRequest

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 : Qtros2NavMsgs::Path

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.

responseReceived(Qtros2NavMsgs::Path response)

Emitted when the service call completes successfully. response is a Qtros2NavMsgs::Path value.

Method Documentation

QJSValue callService(const getPlanRequest&request)

Calls the GetPlan ROS 2 service with getPlanRequest request. Returns a JS promise that resolves with a Qtros2NavMsgs::Path response or rejects with an error string. isServiceReady must be true before calling.
