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

Constructor & Destructor Documentation

◆ ~QgsCredentials()

virtual QgsCredentials::~QgsCredentials ( )
virtualdefault

Destructor.

◆ QgsCredentials()

QgsCredentials::QgsCredentials ( )
protecteddefault

Constructor for QgsCredentials.

Member Function Documentation

◆ get()

bool QgsCredentials::get ( const QString &  realm,
QString &  username,
QString &  password,
const QString &  message = QString() 
)

Definition at line 41 of file qgscredentials.cpp.

◆ getMasterPassword()

bool QgsCredentials::getMasterPassword ( QString &  password,
bool  stored = false 
)

Definition at line 72 of file qgscredentials.cpp.

◆ instance()

QgsCredentials * QgsCredentials::instance ( )
static

retrieves instance

Definition at line 33 of file qgscredentials.cpp.

◆ lock()

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.

◆ mutex()

QMutex* QgsCredentials::mutex ( )
inline

Return pointer to mutex.

)
protectedpure virtual

request a password

Implemented in QgsCredentialsConsole, QgsCredentialsNone, and QgsCredentialDialog.

◆ requestMasterPassword()

virtual bool QgsCredentials::requestMasterPassword ( QString &  password,
bool  stored = false 
)
protectedpure virtual

request a master password

Implemented in QgsCredentialsConsole, QgsCredentialsNone, and QgsCredentialDialog.
