This class is a composition of two QSettings instances:
Definition: qgssettings.h:58
#define QgsDebugMsg(str)
Definition: qgslogger.h:38
static QString sslErrorEnumString(QSslError::SslError errenum)
Gets short strings describing an SSL error.
void collapsedStateChanged(bool collapsed)
Signal emitted when groupbox collapsed/expanded state is changed, and when first shown.
Dialog wrapper for widget displaying detailed info on a certificate and its hierarchical trust chain...
static QString shaHexForCert(const QSslCertificate &cert, bool formatted=false)
Gets the sha1 hash for certificate.
static QgsAuthManager * authManager()
Returns the application&#39;s authentication manager instance.
static QgsNetworkAccessManager * instance(Qt::ConnectionType connectionType=Qt::BlockingQueuedConnection)
Returns a pointer to the active QgsNetworkAccessManager for the current thread.
bool updateIgnoredSslErrorsCache(const QString &shahostport, const QList< QSslError > &errors)
Update ignored SSL error cache with possible ignored SSL errors, using sha:host:port key...
QgsAuthSslErrorsDialog(QNetworkReply *reply, const QList< QSslError > &sslErrors, QWidget *parent=nullptr, const QString &digest=QString(), const QString &hostport=QString())
Construct a dialog to handle SSL errors and saving SSL server certificate exceptions.
void readyToSaveChanged(bool cansave)
Emitted when the configuration can be saved changes.
Widget for listing trusted Certificate (Intermediate) Authorities used in secure connections.
