37 | * Command handler for creation of a new connection for trace control. |
38 | * <br> By supplying arguments for the parameters with id {@link #PARAMETER_REMOTE_SERVICES_ID} and | |
39 | * {@link #PARAMETER_CONNECTION_NAME}, the caller can specify the remote connection that will | |
40 | * be added to the trace control. In case one of the optional arguments is not supplied, the handler | |
41 | * opens a dialog for selecting a remote connection. | |
