[Qgis-developer] [Qgis-user] accessing a web page from within a plug-in

[Rémi Cura]

Thank you very much.
It seems that strangely enough,
using  `QWebView` automatically takes into account the qgis proxy settings.

For the check of connection, it was actually a lot more complicated that we
thought.
The complexity comes from the fact that all QT web querry are asynchronous.

We put a state machine to switch between local and online version when
there is/there is no connexion.

Many thanks for your help.

Cheers,
Rémi-C
