Qt on S40



  • Are there any plans for Qt on S40. Anybody has any info ?



  • I don't think so. Series 40 phones have quite limited resources and Series 40 is s feature phone platform. not a smartphone paltform Series 40 platform uses operating system made for the feature phones (Nokia OS). There is no native API which developers vould use So I don't really think there will be Qt for it.



  • I was thinking whether it is feasible to implement Qt over Nokia OS. But probably not, because, as you said very limited resources.



  • I would not be so sure of that. Remember that Elop even hinted such at move, and that Thiago hinted on the qt-interest mailinglist that there still is a lot of business for Qt within Nokia.



  • Thiago hinted on the qt-interest mailinglist that there still
    is a lot of business for Qt within Nokia.

    I think that means MeeGo and Symbian. Even if Nokia is moving to WP7 development of MeeGo and Symbian will still continue.

    Timo Ihamuotila from Nokia said yesterday:

    We will of course utilize the long-tail of Symbian as long
    as it gives us profitable margin," Nokia's Chief Financial
    Officer Timo Ihamuotila told a UBS Technology Conference.

    So the transition period 2011-2012 relates to product
    creation transition, not sales transition as such," he said.

    So most likely development, sales and support of Symbian will continue several years and at the same time MeeGos is still there too.



  • Ofcourse everything is possible, but I think that porting Qt to Series 40 would be a bit weird decision. If you want smartphone with Qt then there is Symbian which already has Qt.



  • Well, the comment was that Qt was "being evaluated for the feature phone line", or something like that. It could become part of the "internet for the next billion" strategy, whatever that may mean. Thiago was quite explicit in telling us that not all relevant decisions that impact the future of Qt in Nokia have been communicated publicly, but he was obviously not able to go into details. If that means a port to S40 of Qt, I don't know. It could also mean that symbian will be "degraded" to be a "feature phone" OS while only those running on WP7 will be marketed as "smart phone". It could also mean something completely different.



  • bq. It could also mean that symbian will be “degraded” to be a “feature phone” OS

    Don't known how that would be possible because smart phone is not just some marketing term. Symbian is a smart phone OS no matter how you market it. If you would like to make a feature phone with Symbian then you would need to artificially criple the Symbian by making it closed system with no public native APi etc, and that does not make any sence at all.



  • In the earlier days when Qt was just ported to S60, there was talk regarding the feasibility of Qt on S40. But nothing has happened. So I'am pessimistic about that happening now. There is either a technical or political hurdle to it.



  • It is possible.
    But Nokia will not do it. Because of the least cost devices.
    S40 series devices are least cost devices compared to S60.

    Currently Nokia porting Qt or Qt application on limited devices.



  • qtrahul are these Nokia's stand that they won't do it or are these your views ? :)



  • wernt there statements, that Qt will not be used on smartphones (--> WP7,will be for symbian and MeeGo) but for other phones?



  • are we all assuming that smart phones as they are today .. will be the end of world ...
    just being hypothetical here ;)



  • It should be technically feasible. They already have an embedded version of Qt. So it should be possible to port it to Nokia OS. Seems they are not interested.



  • I look at it this way, more and more number of devices will support Qt and so focus on doing stuff on Qt and explore the new mkt opportunities. Even the 150 mil+ symbian phones indicate a significant mkt presence. S40 or not, there are more than enough customers who will be out there and a country like India is vastly untapped on the mobile app front ...



  • Qt for S40 announced. So can we develop in c++ on S40 or will there only be a partial support using Qml only ? Will Qt mobility be supported ? May be it is too early to ask these. But anybody have more info ?

    Exactly. Today's cutting-edge technology is tomorrow's commodity hardware.

    In an "interview":http://conversations.nokia.com/2011/05/26/stephen-elop-in-china-time-for-a-challenger-mindset-video/ Stephen Elop said that Symbian will be supported “at least up to“ 2016.

    Actually what Nokia announced was Qt for next billion. S40 was what came to my mind immediately. But may be not. The next billion thing, seems some thing else. So far we have only rumors, no concrete information regarding what next billion is.



  • Yes, I have seen this next billion and also some posts immediately interpreting this as Qt for S40. But this might be something else. For example the coming feature phone will have better computing power and some light version of Symbian will run on it. Portability is nice but I think developers who seriously consider to enter this market need to look at what Nokia made available now. Also HTML apps is a good option.



  • The Qt version 5.0 will not be supported on Symbian. Symbian will be stuck with Qt 4.8. This information comes from Qt developer days Munich. So next billion is unlikely to be based on Symbian. There are many rumors of a linux based ' next billion ' platform. May be it is based on Maemo. But that is my guess.



  • As I read here http://talk.maemo.org/showthread.php?t=79051
    I could imagine not Series 40, taking where we started this topic, but either new line of Meego devices. It might be that N9 success has moved something in Nokia's mind. Also current four platforms is too much. WP7 plus Meego would be much better, also for developers.



  • There are many sources saying that N9 is actually Maemo Harmattan rather than Meego. We can't know the truth. But since Intel and Nokia partnership is over, Meego is dead. There is a new Intel + Samsung partnership called Tizen which may be called a successor to Meego. It is likely that the Nokia
    plan is Wp7 + Maemo + S40, which replaces the earlier Symbian /Maemo + S40 + S30 strategy or it could be just WP7 + Maemo. We can wait for more information from Nokia.



  • Perhaps you should search for "meltemi".



  • Haha, makes sense :)



  • [quote author="Jayakrishnan.M" date="1320658785"]There are many sources saying that N9 is actually Maemo Harmattan rather than Meego.[/quote]

    N9 is Maemo 6 is MeeGo Harmattan is MeeGo. MeeGo is just a set of specifications and APIs, which are implemented by MeeGo/Core and others, for example Maemo 6, which is then called MeeGo/Harmattan.



  • I too have read some rumors about meltemi, another project named after wind naming convention. But I doubt, how Nokia can predict or determine the number billion, even before the platform is released. There has to be something else. I think feature phones are losing market in India too, since Android phones can be bought at the same cost (Android 1.6 to 2.0). Meego was the only thing that was going to save Nokia! I thought.



  • I wonder how much more Nokia will take to unveil more news about the "Next Billion" or Meltemi. All this waiting doesnt seem beneficial to Nokia itself, nor to the community.



  • I'am really surprised that Nokia have not yet announced any details regarding the ' Next Billion ' platform. The next billion remains a mystery. As a developer there are several questions coming to my mind. Will ' next billion ' replace S40 ? When will we see next billion based phones ? The future of J2me ? Nokia has solid information and roadmap regarding its WP plans. Either Nokia haven't taken a final decision yet on what should power next billion or is this something revolutionary ? Also I don't understand why the term next billion is used for this.



  • bq. or is this something revolutionary ?

    The only revolucionary thing that comes to my mind is Nokia fire Mr. Elop, switch back to Meego and launch a Meego tablet :)
    That would no only be revoluvionary but handsome LOL

    You read the minds of billion people out there.



  • bq. In response to a question at the Dev Days welcome address, Nokia's Kenny Mathers said that the next billion platform was not S40.
