DnsManager#

class DnsManager(QObject)source

DnsManager(settings: Settings, parent: QObject | None=None)

Switches Chromium's stub resolver between system DNS and DNS-over-HTTPS at runtime.

PyQt6 exposes QWebEngineGlobalSettings.DnsMode but not the static setDnsMode() call, so the exported C++ function is invoked through ctypes. DnsMode is passed by value (MSVC x64: pointer to a temporary that the callee destroys), so the shared QStringList payload is ref-counted up once to balance the callee-side destructor.

ProxyManager#

class ProxyManager(QObject)source

ProxyManager(settings: Settings, parent: QObject | None=None)

Routes engine traffic through HTTP / SOCKS5 proxies (applied live) or an HTTPS (TLS-to-proxy) server (applied through Chromium flags at startup).

Chromium owns one network stack per process, so per-space overrides follow the foreground space: switching spaces re-routes traffic and "kicks" each profile's network context so the new configuration is used by the very next request.
