Hi, everyone:
I'm trying to write a browser by QT, and I found the
QNetworkProxyFactory::setUseSystemConfiguration()
could use the proxy server that is set in "Internet Options".
But it just reads this information once. When user changes a proxy
server manually, it still use the old one.
So, I want to know how can I get some event message emitted by system,
and I will reset the proxy settings
when I receive the event.
Does any event can be emitted when user changes the proxy information
in Internet Options?
Best Regards!!

IE probably broadcast a WM_SETTINGCHANGE to all top level window with the
registry key in lparam.
Note when the user press OK in IE option window and multiple settings are
changed, you may get a bunch of WM_SETTINGCHANGE messages.
