This class is a composition of two QSettings instances:
Definition: qgssettings.h:58
QVariant value(const QString &key, const QVariant &defaultValue=QVariant(), Section section=NoSection) const
Returns the value for setting key.
#define QgsDebugMsg(str)
Definition: qgslogger.h:38
static QList< QSslCertificate > certsFromFile(const QString &certspath)
Returns a list of concatenated certs from a PEM or DER formatted file.
Dialog wrapper for widget displaying detailed info on a certificate and its hierarchical trust chain...
QgsAuthSslImportDialog(QWidget *parent=nullptr)
Construct dialog for importing certificates.
static QString greenTextStyleSheet(const QString &selector="*")
Green text stylesheet representing valid, trusted, etc. certificate.
static bool certificateIsSslServer(const QSslCertificate &cert)
Gets whether a certificate is probably used for a SSL server.
static QString getSslProtocolName(QSsl::SslProtocol protocol)
SSL Protocol name strings per enum.
static QgsAuthManager * authManager()
Returns the application&#39;s authentication manager instance.
void setValue(const QString &key, const QVariant &value, QgsSettings::Section section=QgsSettings::NoSection)
Sets the value of setting key to value.
const QList< QSslCertificate > trustedCaCertsCache()
trustedCaCertsCache cache of trusted certificate authorities, ready for network connections ...
void readyToSaveChanged(bool cansave)
Emitted when the configuration can be saved changes.
