Hi Slava,
Thank you for your response! With these links I can indeed figure out the
current state of the network connection in Python by reading those files.
Now I just need to figure out how I can add it to Sailfinder without a lot of
rewriting.
Kind regards,
Dylan Van Assche

Hi Dylan,
From QML, the easiest way is probably to monitor
/run/state/providers/connman/Internet/NetworkState and
/run/state/providers/connman/Internet/NetworkType with ContextProperty object.
Google for "qml contextkit contextproperty" to find some examples. That way,
statefs monitors connman state for you and you monitor statefs.
You can achieve the same result by directly monitoring the connman state over
D-Bus. Then libconnman-qt is your friend. It's a C++ library with a QML plugin
(MeeGo.Connman). That requires a bit more code but takes statefs out of the
picture.
There are also Qt network configuration APIs but those are even more
complicated and not all of those might work the way you would expect them to
work. But this is the most platform-independent API in case if that is
important for you (probably not). Internally it also talks to connman.
Connection selector has a D-Bus API which is easy enough to figure out with
dbus-monitor. However it's not an official API and it's more or less guaranteed
to change over time and break your app. Think twice before starting to use it.
Cheers,

Hi Sailors,
For my app Sailfinder I have received a bug report about the network
connection. When switching between mobile data & WiFi the app misbehaves.
I want to detect the current network state to avoid thsi problem. I thought of
several possibilities:
-
Ping everytime to my website before doing other requests (expensive, better
not).
- Use MCE module which expose the network states in a file (that's what I found
on the sailfishos.org website, no more extra information). This option is the
one I want to try :)
-
...
And if network isn't available I want to show the network connection dialog but
I haven't find any information about it. Can someone help me with it? If
possible, in a Harbour way since Sailfinder is also available in the Jolla
Store.
Kind regards,
Dylan Van Assche
