QPlaceReply ¶

概要 ¶

详细描述 ¶

QPlaceReply and each of its specialized subclasses manage the state and results of their corresponding operations. The QPlaceReply itself is used for operations that have no results, that is, it only necessary to know if the operation succeeded or failed.

finished() signal can be used to monitor the progress of an operation. Once an operation is complete, the error() and errorString() methods provide information on whether the operation completed successfully. If successful, the reply will contain the results for that operation, that is, each subclass will have appropriate functions to retrieve the results of an operation.
