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

[Rémi Cura]

Hey dear Qgis list,

my question is related to network and plugin.

>From within our plugin <http://remi-c.github.io/interactive_map_tracking/>
we would like to display a User Guide
<https://github.com/Remi-C/interactive_map_tracking/wiki/%5BUser%5D-User-Guide-%28simplified%29>
.
This guide already exists on GitHub, and it would be good to directly
display the html fo the github page in the plugin.


Of course internet is not always accessible, so we have a local version of
html pages in the plugin directory.

SO there is 2 questions :
- Are we sure that using the `QWebView` to connect to internet will include
the QGIS proxy settings? (what is the best practice here?)
- How to check if it is possible to access an internet page, so that if it
is not possible to get the online version, we could fall back on the local
version?

Thanks for your time ,
Cheers,
Rémi-C
