Also, it seems that the Qt version of Mapbox GL native is fairly new and has seen significant updates and fixes in new versions, so there's a significant benefit in having a separate package for this as getting it via a Qt LTS release means quite a long delay.

And still my custom solution is not even close to the quality of Mapbox's maps, in part due to my lack of design skills, in part due the low detail level of tiles from OpenMapTiles.com. It would be best to have some kind of a platform solution as Mapbox's maps are unreasonably expensive for a hobby project once past the free plan. It's likely worth asking if Mapbox would be interested in some kind of a deal, getting some exposure and testing for their Qt version. -- Osmo Salomaa ___ SailfishOS.org Devel mailing list To unsubscribe, please send a mail to devel-unsubscr...@lists.sailfishos.org

[SailfishDevel] Resolution-independent in-app icons
Hello, SFOS has standard sizes for application launcher icons and Silica has stock icons, whose sizes (I assume) vary by device, but how should I handle custom in-app icons, e.g. a position icon in a map application, so that it would look right on different pixel-density screens? I tried using a large PNG or SVG and having QML scale that to one of the Theme.iconSize* constants, but the result of such downscaling is not smooth, even when using Image's smooth=true. Additionally the QML documentation says there's a possibly significant performace cost to smooth scaling. This implies that I'd need different size PNGs on different devices and show those 1:1 without scaling. So, is there some SFOS image resizing script I can run on RPM's post-install to generate the right size icons from SVGs or large PNGs? Or should I just roll my own solution that packs in icons of different sizes and loads the closest match at runtime? -- Osmo Salomaa ___ SailfishOS.org Devel mailing list To unsubscribe, please send a mail to devel-unsubscr...@lists.sailfishos.org

Re: [SailfishDevel] About applications presenting a map interface
Hello, 03.09.2015, 08:14, juice kirjoitti: 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.
