Type Documentation
enum class QWebEngineGlobalSettings::SecureDnsMode
This enum sets the DNS-over-HTTPS mode used by the DnsMode structure:
| Constant | Value | Description |
|---|---|---|
QWebEngineGlobalSettings::SecureDnsMode::SystemOnly | 0 | This is the default. Use the system DNS host resolution. |
QWebEngineGlobalSettings::SecureDnsMode::SecureWithFallback | 1 | Enable DNS-over-HTTPS (DoH). DoH servers have to be provided through serverTemplates in the DnsMode structure. If a host cannot be resolved via the provided servers, the system DNS host resolution is used. |
QWebEngineGlobalSettings::SecureDnsMode::SecureOnly | 2 | Enable DNS-over-HTTPS and only allow hosts to be resolved this way. DoH servers have to be provided through serverTemplates in the DnsMode structure. If the DNS-over-HTTPS resolution fails, there is no fallback and the DNS host resolution fails completely. |
Function Documentation
bool QWebEngineGlobalSettings::setDnsMode(QWebEngineGlobalSettings::DnsMode dnsMode)
Sets dnsMode for DNS-over-HTTPS host resolution.
This function returns false if the serverTemplates list in the DnsMode structure is empty or contains URI templates that cannot be parsed for SecureDnsMode::SecureOnly or SecureDnsMode::SecureWithFallback. Otherwise, it returns true meaning that the DNS mode change is triggered.
