Qt + Windows Phone 7



  • Hi all,

    I'm new to this forum, but not new to Nokia. I have a question which is mostly related to mobile technology and recent news.

    Recently Nokia has confirmed it will be moving to Windows 7 on its handsets. Although Symbian will be available on existing handsets, what are the implications of this with regards Qt? Does an application written in Qt for a Symbian phone still work on Windows 7 without any re-coding?

  • Hello,

    As far as we can see, Qt will not be ported to WP7, you'll have to rewrite everything for these phones.



  • dourouc05,

    Thanks for this. I was fearing this might have been the response to some degree. I am learning the very basics of Qt programming, and this announcement was kind of mis-timed as it means I was about to start on something that may not have a future.

    Windows does use the .Net Framework embedded into it, so I might do some digging about to see if the new Windows 7 Nokias will have .Net, if Qt can be ported to it, and if .Net can be ported to Symbian. I currently have a Symbian phone and .Net experience, so .Net converted to Symbian would be very beneficial to me.

    I'll let you know what I find.



  • hello,

    I started making phone applications for Windows 7, it is based on XAML and c sharp / vb.net. I think

    in the future, the qt Flexibility will allows us to make application for WP7 with QT .So ,you will can develop application for symbian, Meego and WP7 (it's a dream but not Thing Is Impossible With qt)



  • If you want to develop for windows device, then you have the .net platform.

    Currently with the use of Qt we can develop the application for the Symbian and Meamo devices. And in future for the Meego devices.



  • Just for clarity, I hope you mean to ask about if your Qt applications will work on Windows Phone 7, not on Windows 7 (the desktop OS)? They are hugely different platforms. Qt works fine on the latter, but not at all on the first.



  • Windows 7 Phone is a new platform with many things to be improved. I would not be surprised if Qt becomes compatible to WP7 within a few years. And certainly I hope it will be ported :)



  • The official announcement of Nokia is: no Qt port to WP7, sorry.



  • oh no :(



  • But was obvious, from what I've understood, Qt use c++ and win phone t doesn't accept that lunguage.



  • WP7 doesn't have a native SDK; you can only use SilverLight. That means that at the moment, you can not port Qt to WP7. However, Nokia is supposed to have full access to WP can do whatever they like with it in terms of customization. I am not saying they will, as they announced they would not, but I suspect that is they really wanted, they could.



  • The view of most developers that I have spoken to is that the market is only really willing to adopt two Mobile Operating Systems and unless something seismic happens those are going to be iPhone and Android. My big concern is not whether QT will be supported on Windows 7 Phone, but what will happen to QT in the long term. In my opinion, Nokia have backed the also ran and in this day and age, that may prove to be a terminal mistake! If Nokia have any sense they would get an Android port out for QT ASAP and then pray that they can make some money that way - Will Microsoft really let them do that - What do you think? - I am not sure things really look good for QT any more in the mobile space.



  • I think that this scare level is too high for the current state-of-the-art.

    I develop far from 1980 and I saw a lot of changes. When the only mobile phone was the only you those used by Scott to ask Spock to return on Enterprise these changes all was involving only the PC. What this has taught? that is the software is done in a right way, consciously, it can be ported without great difficulties.
    The real question / hope is if other platforms have same features for interface development, but the answer is - with something already not clear - yes. Exploring several development platforms like X-Code and not only, as a matter of fact almost the major platforms are aligning their capabilities, because we see similar features on apps developed on apparently very different environments.

    Consider also that back the scene there is always Nokia: this means that I can expect on different platforms from the same producer similar methods and porting.

    No one has never worked on web frameworks like ZEO? They work with python, integrated with java, css, html, xml dialects, c/c++ and more. But a lot of people develop and create good products. Here the situation is a bit simplified: we all work with c++ and some java. Qml ... We can hope for some similar scripting support, sure!



  • In future,When Windows Phone 7 for Nokia available, Nokia definitely want their Qt applications and products to run in WP7 based Nokia devices.

    Currently Qt is ported only in Symbian, maemo and meego.

    After 11-2-11, Nokia has changed their strategy, and want to go with WP7, So they will definitely thinking of porting Qt in Windows Phone 7.

    Otherwise Qt will find less audience.



  • Don't count on it. The messages from Elop were very clear: no Qt porting.



  • So, They want to use Qt only for Symbian, Maemo and Meego based devices.

    Ya, At 11-2-11 ,they send one letter to all developer this "developer letter":http://blogs.forum.nokia.com/blog/nokia-developer-news/2011/02/11/letter-to-developers

    I am talking about after one year.



  • You also have Qt for desktop systems, embedded devices (e.g. industrial devices, etc.) ... Smartphones is not all that exists.

    qtrahul, so at this point I have no clear what do you mean. You write that Nokia port Qt on W7 but as is wrote in the letter you cite too, Andre is right. I thought too that Nokia opened a new way that names W7 that shortly coexist with Qt.
    What seems a little illusion is the words about meego, if you read more about on the net. It is not ready yet for commercial devices and his destiny seems to be the same of maemo platform... but this last is only my opinion.



  • @Gerolf: you anticipated of seconds what I was writing. Qt is for a lot of platforms, and Nokia is only one of the (big) players that works in Qt. The Qt community is opensource, and Nokia had the agreement to manage this but the prior condition is to leave Qt open and independent. As you can imagine thinking beyond Nokia devices to KDE desktop and embedded.



  • There will not be a Qt port to WP7 from Nokia from what we know today and from what the business plans of Nokia are today. Point.



  • Exactly. I tink that this "point" had been written in all colours and fonts here and not only. Is possible that someone think that with and intense thought that this can be ... then it became real ? :)



  • Well. Qt's been ported to Android and iOS (to some extent at least) among others, so I don't see why there couldn't be a community port to Windows Phone as well. Fingers crossed.



  • If you get a C++ compiler and the C++SDK for WP7, it would be possible. AFAIK, MS does not give that out....



  • [quote author="Gerolf" date="1320874639"]If you get a C++ compiler and the C++SDK for WP7, it would be possible. AFAIK, MS does not give that out....[/quote]

    There are rumors that the next release of "Windows Phone called Tango will bring C++ support.":http://www.phonearena.com/news/Windows-Phone-Tango-will-speak-120-languages-might-bring-native-C-support_id26391

    Having in mind also several recent blog posts from Digia about Qt Commercial on Windows 8 tablets I hope that Qt will be running on Windows Phone in (near) future :)

    Apparently (I haven't looked into this much yet), it is possible to build (homebrew) C++ libraries for WP7 already:

  • Well, but you can't publish them using the app store, can you?

    There is already a "thread":http://developer.qt.nokia.com/forums/viewthread/13919/ discussing native code support on Windows Phone 7; it may qualify for a merger.



  • Yes, I have the first hand info that C++ support is coming in the upcoming WP7 update. Apart from external factors if Qt is ported to WP7 then there will be more apps to its WP7. It is a value addition.





  • [quote author="q8phantom" date="1328173411"]Can someone confirm this news??[/quote]

    I haven't seen anything official yet. May be Nokia and Microsoft will announce it during Nokia developer day at MWC.



  • That is so bad ! How will the Qt community survive in the future ? What is the Nokia's strategy for Qt in the future ?



  • The question is: what is Nokias strategy for Nokia in the future?

    Qt is what "we":http://qt-project.org/ make of it.

    Hi, as mentioned really often till now, Qt is not only mobile. Qt comes from the desktop world, was extended to embedded devices and at the end to mobiles. And Qt is open source. It will survive.
