I pushed my testing project to
https://github.com/oniongarlic/harbour-are

but I don't even know if it builds at this time as I was going to add
GPS support but never finished it.

I've been playing around with libosmscout, it uses vector data and the
data/rendering can be customized with various style files.

http://onion-garlic.blogspot.fi/2015/02/interactive-piste-map-on-sailfish-os.html

Unfortunately it had some rendering issues (hiding stuff when zoomed in
too close), but this was in February, I haven't done anything with it
since so could be already fixed upstream.

Interesting, I can give it a try and let the other know hopefully by the
end of the week.
Kaj-Michael, any chance to have your sample project to start with?
Thankyou

Re: [SailfishDevel] About applications presenting a map interface

[David van rijn]

Hi Guys,

I definitely agree that there should be an easy way to add a map in any
application. This would make things so much more efficient. I believe there
were some mails earlier in this group about storing all the cached tiles in
the same place, so apps can share them.

A while ago i started with bulding my own
 slippy-map application to do
just this. It uses Qt scene graph, so it should be really quick and
efficient. It is not finished yet (rotating and zooming are hard to
combine), but it might be interesting nontheless.

Cheers,

David

Yeah, I made the "Well known map data path" proposal a while ago but 
unfortunately there were not many reactions or feedback since then. But 
everybody is of course welcome to use or extend the specification. :)


Also on a related note - I have been recently working on a rewrite of 
modRanas tile storage code to make it much more flexible & robust. The 
result should be that in the future modRana should be able to look for tiles
at multiple places simultaneously - for example in its own tile storage 
location, in a well known/shared tile storage location or even possibly 
in the tile storage locations of other apps (if compatible). :)

Any idea if you can make some use of the mapbox-gl-native vector map 
renderer[2) ? Maybe as a special tile provider ? The output looks 
marvelous and it's also C++ and they even have some initial Qt 5 
support[3] (QWidget only at the moment though).

Hi Juice

I'm using Pinchmap from Foursail, it's a qml/javascript implementation of a 
slippery map, and works great, at least for my use ;)

Re: [SailfishDevel] About applications presenting a map interface

Hello,

I see that currently QtLocation and QtPositioning are still not
allowed in Harbour. This seems to me that I cannot use a Map object
in QML.


QtPositioning is allowed, but QtLocation not. You conclusion is correct 
though -- you cannot use Map. Jolla seems to want to wait for QtLocation 
to be released as a stable part of Qt. It is a "technology preview" in 
Qt 5.5.



What is approved the method to present a map interface (openmaps for
example) in an application and still have it possible to submit the
application to the store?


You need to bundle something in and ship it with your application.

Effectively, Jolla is currently telling application authors to either 
(1) not write applications with maps, (2) not ship via the official 
store or (3) to bundle their own map component.


If option (3) is least bad for you, you can take a look at the several 
map applications already at the Jolla store, some of which are open 
source. Each of them bundle a different legacy map component that is 
clearly less native, less smooth and less performant than QtLocation. 
The QML PinchMap [1] is probably the easiest solution. If you don't need 
something quite ready yet, but want a modern solution, take a look at 
Mapbox GL [2].


Best would be if you could convince Jolla to allow QtLocation. I suspect 
their stability worries are exaggerated, especially compared to the lack 
of stability worries of those legacy components.
