Hi all,

Only one argument.

I don't see any point in moving this to QtProject as we don't have Sailfish OS 
platform upstreamed.
Just let's not miss the moment when it become upstreamed. :-) Things move very 
fast recent days. Rostelecom and Russian universities make much effort to 
promote and advance it. Since it is the only mobile OS certified by FSS, and 
only approved by government - it will be the primary OS applications will be 
developed for in government and corporate sectors where security is a corner 
stone. It is sales hit in Russia currently among civilian users 
Really? Almost nobody is aware of its existence, even in IT circles, and the 
only device can be bought in one place. AFAIK it has no presence in mobile shops

You can buy Sony Xperia X and install SailfishOS X on it, I did it this way. Sony Xperia XA2 port is on the way.

and become upstreamed very fast with and like Russia become upstreamed already 
and become much more developed in nearest future.

Or You mean upstreamed in QtProject? :-) Let's make it upstream then! :-)

Agree with the rest.

  Hi all,

  I highly doubt that it can be done as a part of GSoC and I don't see
  any point in moving this to QtProject as we don't have Sailfish OS
  platform upstreamed. We just need this style to make QQC2 applications
  look native on Sailfish OS. I think that we'll have to rely on
  closed-yet components and the style is not going to look nice with

  That said, I see a number of issues and I hope that we'll discuss and
  agree on some changes to the QQC2 API:
  1) I would like to propose ComboDelegate — a pair of ComboBox and
  Label, combined in a platform-specific way (similar to CheckDelegate
  and RadioDelegate).
  2) We also need a delegate to display a label and an associated value.
  It is named "DetailItem" in Silica, but I would agree to go with a
  name like ValueDelegate.
  3) Yet another point is that we need to properly style delegate
  descriptions, so I want to propose "description" property at least for
  Combo, Radio and Switch delegates (we even don't have a 'buddy'
  property here, though it still would be very hacky to go in this way).

  Probably it makes sense to start another thread to discuss Qt Quick
  Controls 2 API, but I need at least three weeks to think and
  experiment with what we have right now. :-)

  My work is available at
  https://git.merproject.org/Kaffeine/qtsilicastyle (compatible with Qt
  5.9 and 5.10), but I don't think that it can be interesting for anyone
  in its current shape.

   Yes, I have contacted Jolla devs, got answer:

    Providing Sailfish support for Qt Quick Controls 2 would definitely be

   Silica Componets source is not public, yes :( But I've got device where I

   Alexander Akulich (Kaffeine) from Open Mobile Platform is helping me a lot
   too, he recently created:

   For now current state is:

   5.10 private API chaged compating to 5.9:

   Alexander is testing with 5.9 LTS on SailfishOS
   and me with archlinuxarm 5.10
   so I'm thinking now how to provide better compabilty for both :)

   looks like #ifdef approarch is not helping yet, should investigate more time

   We think this would be best in a repo outside of qtquickcontrols2.git.

   The process for creating a playground repo is documented here:


   Have you discussed this project with the Sailfish devs, by the way?
   Perhaps they would be interested in integrating your efforts upstream.

   One potential problem I see is that it seems that the source code is not


   The closest thing is this repo, which doesn’t seem to be complete:


   How do you plan on implementing the style in light of this?

   Speaking for myself: I would be happy to answer any questions you may have

   aside enough time to be a mentor for this.

   Quick Controls 2 Sailfish Silica Style

   Hi, Aleksey Kontsevich! Thank you for your support, I do agree that
   Sailfish OS is receiving a huge contribution from Russian speaking
   developers and focusing on other local markets too. There's also related
   AsteroidOS community about smartwatches. They have a demo [1]

   Talking about popularity: from my point of view, while Microsoft is
   providing their Metro unified look for desktop and Intel-based tablets (and
   Xbox) for example, looks like they do not have any plans for new mobile
   devices (I mean arm-based) to provide. While Sailfish OS is mobile OS with
   GSM-stack support for real arm-based systems. [1] Correct me if I'm wrong, I
   do not want to mislead anyone.

   Mitch Curtis, thank you for your feedback sincerely. I do understand your
   skepticism about yet another controls in mainline to support. (but I do not
   share this personally :)

   I'm new to qqc2 internals. I've cloned qtquickcontrols2 repo 5.10.1 brach
   (to play on my Arch Linux system). Dependency from some private APIs looks
   tricky for me at first glance. I'm trying to sort out. I'm not against
   providing silica style as some custom repo, the result I want to get is open
   source solution to run Qt application in my personal environment with native
   Silica look and feel. Will be happy to get any hints about basic repo draft
   in that case (should I look at Kirigami approach?)

   Anyway, as I wrote at my GSoC proposal, GSoC campaign is just money
   support, I love Silica style, using Sailfish OS for several years and can't
   stand that no one is willing to port it to modern QQC2 approach :) I guess
   it could radically change skepticism about qt quick controls approach in
   general from ios and android developers.

   Hi all, my 2 cents here:

   >Sailfish OS).

   Sailfish OS become VERY popular in Russia and in Latin America, and for
   people who wants their data and communication be secure. Market in Russia
   growing very fast, Sailfish OS devices are hits of sales, leading
   universities created courses for Sailfish OS, government certified
   it for corporate and government use and since 2019 all mobile applications
   from national software list (government and corporate use) should work in
   Sailfish OS (according to import replacing law all applications should be
   Russian-native and secure).
