Detailed Description

Interface for requesting credentials in QGIS in GUI independent way.

This class provides abstraction of a dialog for requesting credentials to the user. By default QgsCredentials will be used if not overridden with other credential creator function.

QGIS application uses QgsCredentialDialog class for displaying a dialog to the user.

Object deletes itself when it's not needed anymore. Children should use signal destroyed() to be notified of the deletion

retrieves instance

void QgsCredentials::lock

(

)

Lock the instance against access from multiple threads.

This does not really lock access to get/put methds, it will just prevent other threads to lock the instance and continue the execution. When the class is used from non-GUI threads, they should call lock() before the get/put calls to avoid race conditions.
