[Interest] QtCreator on kubuntu says: "No qmlscene installed"
I just installed Qt Creator 4.5.2 from kubuntu apt sources. It installed qmlscene + qt development files at the same time. I can see clearly there is a qmlscene executable right next to qmake in the same directory: /usr/lib/qt5/bin How do I get rid of the "no qmlscene installed" warning? ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest

If you only use raster tiles then osm should be just fine! I guess it should be much easier to use as a starting point for your own plugin too.

It's not wrong to use const signals. That check is for developers that don't like changing state from const methods (and a signal implies state was changed). If it doesn't bother you then you can disable the check. But I'll remove it from the default group, make it opt-in and update the readme. As you're not the first one to ask.

[Interest] clazy - why signals shouldn't be const?
Hi, perhaps not the best list to ask, but hopefully somebody more familiar with clazy will comment. Why does clazy complain about const signals? While I agree marking signals as const is not terribly important, I've had a few situations in code where I was emitting from const method - and then it only works when the signal is const, too. Besides, marking a signal as const does not result in any loss of performance etc. Is there any strong reason not to mark signals as const? For reference: https://github.com/KDE/clazy/blob/master/docs/checks/README-const-signal-or-slot.md "For signals, it's just pointless to mark them as const." ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
Re: [Interest] qtLocation and mbtiles
Hi Thanks Ola for your reply and advise. I gave it a try and it is working nicely (the server is in a thread of the main application as you suggested). I used the osm plugin instead of mapbox-gl, is there any reason why mapbox-gl would be more advantageous? I might anyway go for the full subclassing method, because I also have security issues (some of the mbtiles contain encrypted tiles and that way it is too easy to catch them once decrypted). I should also find a way to avoid caching, etc. Thanks again Philippe Le 07-07-2018 20:31, Ola Røer Thorsen a écrit : >> I need to create a plugin for qtLocation that would use a local mbtile sql >> database instead of an online provider or a directory.
