Detailed Description

\inmodule QtLocation

Since

5.6

The QPlaceReply class manages an operation started by an instance of QPlaceManager and serves as a base class for more specialized replies.

The 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.

The 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.

contentUpdated

void QPlaceReply::contentUpdated ( )

signal

This signal is emitted when this reply has updated content available.

Depending on the plugin, this signal may never be emitted or emitted multiple times before \l QPlaceReply::finished() is emitted, as some backends are able to return the requested content asynchronously and incrementally.

Note

Do not delete or deleteLater this reply object in the slot connected to this signal. Do it only upon \l QPlaceReply::finished.

errorOccurred

void QPlaceReply::errorOccurred ( QPlaceReply::Error  error, const QString &  errorString = QString()  )

signal

This signal is emitted when an error has been detected in the processing of this reply.

The finished() signal will probably follow.

The error will be described by the error code error. If errorString is not empty it will contain a textual description of the error meant for developers and not end users.

This signal and QPlaceManager::errorOccurred() will be emitted at the same time.

Note

Do not delete this reply object in the slot connected to this signal. Use deleteLater() instead.

Returns the error string of the reply.

The error string is intended to be used by developers only and is not fit to be displayed to an end user.
