This class is a composition of two QSettings instances:
Definition: qgssettings.h:57
#define QgsDebugMsg(str)
Definition: qgslogger.h:38
static QString sslErrorEnumString(QSslError::SslError errenum)
Get short strings describing an SSL error.
void collapsedStateChanged(bool collapsed)

Dialog wrapper for widget displaying detailed info on a certificate and its hierarchical trust chain...
static QString shaHexForCert(const QSslCertificate &cert, bool formatted=false)
Get the sha1 hash for certificate.
static QgsAuthManager * authManager()
Returns the application&#39;s authentication manager instance.
static QgsNetworkAccessManager * instance()
returns a pointer to the single instance
bool updateIgnoredSslErrorsCache(const QString &shahostport, const QList< QSslError > &errors)
