To use a single PositionSource object you need to place it in a scope that is accessible from both your cover and application pages. Having two or more PositionSource objects works but unnecessarily increases the resources (memory, processing, and IPC communications) used by your application. Which is why I would suggest using one. > And as you can see in the archive page, all your mails have gone to the > mailing list, the one you've forgotten the CC you had added it to the To > field.

Hi all, my app is far away from being a test object ;) I've just created the C++ source to check if it is giving me two different accuracies (vertical and horizontal) and I never removed it. But if that found a bug, I'm glad that I could help... :D Sorry to be slightly offtoppic, but a small question on this: what would be the best practice then if I would need the position in QML and in C++, or in two different pages in QML? Shouldn't I use two PositionSources? I have this problem for my app if I want to show the position in the app cover... And as you can see in the archive page, all your mails have gone to the mailing list, the one you've forgotten the CC you had added it to the To field. Greets, Marcel Am Montag, 13.

Re: [SailfishDevel] GPS not turned off if app exits without stopping the GPS
Hi Aaron Thanks for you rapid answer. I am on my way to work, I will play around with this further when I get back home this evening (Swiss Time). So far, on both the N9 and Jolla I used the presence of the GPS icon as an indication that it was running / not running. Once I have run the tests you suggest I will update this thread, Cheers Chris Zitat von "Aaron McCarthy" : Hi, On Mon, 13 Jan 2014 08:11:05 christopher.l...@thurweb.ch wrote: I will call this a behaviour for the moment. Yesterday I noticed that if an app that uses the GPS exits without stopping the GPS, then the GPS remains running on the Jolla. How did you confirm this? Presence of the Location icon on the lock screen? I compared this to my Nokia N9. On that device if an app using the GPS exits (e.g. the user closes it), then the GPS stops soon after that app has exited (even if the app does not explicitly shut the GPS down). On the N9 this even works with multiple apps open using the GPS. In this test, when the last GPS-consuming app exits, the GPS shuts down. This is expected to work. Both the Geoclue master and the provider processes monitor DBus disconnections and will clean up any associated interfaces. The provider processes will then close 30 seconds after there are no more connections. How to test that geoclue-master is working: Run /usr/lib/qt5/bin/qdbus org.freedesktop.Geoclue.Master | grep '/org/freedesktop/Geoclue/Master/client' | wc -l to see how many processes have started positioning. Run the above command, expect 0 Run sailfish-maps Run the above command, expect 1 pkill -9 sailfish-maps Run the above command, expect 0 It is harder to test this functionality in the providers as the number of connections are not readily available. Can you check whether there are any client interfaces exported by geoclue- master with the above command. Also what geoclue processes are running (ps aux | grep geoclue).

[SailfishDevel] GPS not turned off if app exits without stopping the GPS
Hi I will call this a behaviour for the moment. Yesterday I noticed that if an app that uses the GPS exits without stopping the GPS, then the GPS remains running on the Jolla. I compared this to my Nokia N9. On that device if an app using the GPS exits (e.g. the user closes it), then the GPS stops soon after that app has exited (even if the app does not explicitly shut the GPS down). On the N9 this even works with multiple apps open using the GPS. In this test, when the last GPS-consuming app exits, the GPS shuts down. Chris ___ SailfishOS.org Devel mailing list
