Summer'12 Device Program/Qt 5 Mobile Projects

We are looking for brave & experienced developers willing to port or develop apps running on top of Qt 5 before its finally release. Currently Qt 5 alpha is released, the beta version is expected during June and the final in August/September.

The main motivations for this activity are mixture of:

  • Helping testing Qt 5 itself and providing feedback while it's alpha/beta.
  • Helping testing the Qt 5 libraries for the Nokia N9.
  • Getting stories of real apps ported from Qt 4 to Qt 5. Trivial? Horrible? What are the pain points? And what about Qt Creator and the documentation available?
  • Getting developers to play with the new toys: Qt Quick 2, textures, transitions, graphics / video effects, raw OpenGL ES stuff, post-Mobility APIs, the new Qt WebKit, JSON DB, ongoing R&D on PhoneGap own JQuery based experiments...

This is the same motivation we have for the QtonPi program, but for mobile development the N9 provides a touch display and many more sensors and hardware features that bare bones boards are missing.

    • Server down? The link with mobile is not clear. Please explain.-- qgil 20:46, 30 May 2012 (UTC)
    • FirmaXML is an application to digitally sign document under BDOC standard (a profile of XAdES - XML Advanced Digital Signatures). This app is developed using QML, Qt and C++. The idea is porting FirmaXML to provide an intuitive application in order to verify digitally signed documents and sign them in mobile devices.
  2. MagicTag (Anylize song wave and tag it with the right tag), by Tong Zhang (lovewilliam) - Experienced at qt development and embedded system. Had been contributed a lot of patches to the community. Had been working on an linux distribution for a long time MagicLinux. writing patches and build the distribution. And I have experience developing hw and software on other meego based devices :) OpenWaveRadioeg. . Qt Ambassador. Some of my patches can be found here. Now I'm currently studying in Software college , Shandong University and having a good time in the Embedded system lab. I'm doing some porting job recently on an TI board(cortex-a8) to get qt5 run on it. :-) Willing to get a N9 to port my qt4-qml based apps to work with Qt5. And develop more interesting things with qt5 on n9.
    • Can you please point to your patches / contributions? Thank you.--qgil 20:50, 30 May 2012 (UTC)
  3. gNewsReader, by Yogeshwar P (yogeshwarp) - gNewsReader is fully featured Google reader client with easy and fast UI written in QML and utilizing QT-Components. also supports sharing links to Pocket/Instapaer/Facebook and Twitter. Related links [1], [2]. plan to port this to Qt 5
  4. VirtualVoiceNet, by Stuart Marsden (stuartmarsden) - This application provides a push to talk all informed very low bandwidth voice network. It uses multicast and encodes voice using codec2 which provides very low rate voice. It is currently a QtWidget based app but plan to port to Qt5 with a QML interface. This would be an ideal mobile app as it would allow disconnected communities to form a mesh network using B.A.T.M.A.N. and then talk. Could also be used at conferences or family gatherings to aid communication. Planning to have this true multi-platform (am waiting for a QtonPi and already runs on the desktop).
    • Can you share screenshots, feedback, installable binaries or something more than the git repo link? Also more information about your Qt skills and your readiness to play with Qt 5 unstable. The project sounds very interesting, congratulations for the idea.--qgil 21:06, 30 May 2012 (UTC)
    • I will make a screencast/video later today to show the concept. I can also make a linux binary with the bundled library. It should just rely on having Qt 4.8 (nothing earlier as I use multicast which only appeared in 4.8). I do not have Qt set up on windows as I never use it these days but I could if needed. I have tinkered with Qt for years just writing a few small programs. I have Qt5 alpha installed and have begun porting on the desktop. I also have QtonPi ready to go when I get the device so I am very happy to play with unstable. I was serving as a communications officer in the Army but have just retired and moved to Finland so have much more time to dedicate to programming which has been a hobby until now.
    • Have uploaded a video to Youtube which tries to explain the purpose of my application. A bit artificial as I am sending and receiving on the same machine but it shows the idea. Virtual Voice Net Video. Am going to make a stable binary and post a link soon.
  5. Simple Timer Plus, by Tomi Korkalainen - Simple Timer Plus is an elegant and simplified Qt/QML timer app for everyday timing purposes.
  6. QtRadio ghpsdr3-alex, by Andrea Montefusco (iw0hdv) - Project ghpsdr3-alex is an open source, multi platform (Linux and Windows), client server, Software Defined Radio software for HAMs, able to run with many SDR hardware, both QSD and DDC. The GUI is already being developed in Qt 4.x on Desktop edition and is fully functional on Windows and Linux: albeit there is a specific version for Android, I am evaluating the chance to port it to Qt/QML.
    • Can you please explain the project in the context of mobile? Sorry, not a specialist in the topic.--qgil 21:24, 30 May 2012 (UTC)
  7. QAD Apps, by Juhapekka Piiroinen (juhapekka,jppiiroinen) - I am a Nokia Certified Qt Specialist, Qt Ambassador, QtOnPi Device Program member + I have published 14 QAD prefixed applications in Nokia Store for N9. I would like to port all of them to Qt5.
  8. Frosty Window, by Nishith Mahajan (Nishith) - An Open GL project which will try to paint random crystallized water on the phone based on the users interaction. It could be used to create various images by the user and shared. I am a QT ambassador and this application was one of the runners up in the Alphalabs.cc event organized by Nokia.
    • OpenGL is definitely one area of interest. But is the original written in Qt? What is your Qt related experience and are you ready to deal with Qt 5 unstable? Do you have more OpenGL projects in the pipeline?--qgil 21:34, 30 May 2012 (UTC)
    • the video you are seeing is of Windows Phone done for the competition but yes As I am basically a Qt programmer I did make its first prototype in Qt as that was easier for me. But I might have to start from scratch as it was just a proof of concept. I have been working in Qt for the past 4 years and am skilled enough to handle the instability of QT 5. I have used unstable versions of orbit and QT 4.7/4.8 for Symbian Belle photos application(Official Nokia Application in X7 , N8 and its variants). I have made various applications like FriendsChat, Hotline and Sainsbury. Other than this my current projects are also using Qt4 and OpenGL but those are more of Signal Analysis projects for desktops.
  9. MeeCast, by Uladzislau Vasilyeu (vasvlad) MeeCast is very populary multiplatform highly customizable open source weather forecast client.
  10. mediadownloader and StarMenu QML component, by Marco Bavagnoli Qt Ambassador,QtonPi Member. I have created some useful wiki articles and opensource QML components.
  11. Shutdown,GApp,WakeOnLan and QuickCall for Harmattan (Qt/QML), by Felipe Crochik (fcrochik@maemo, fcrochik@qt-project). I am a Nokia Certified Qt Specialist, Qt Ambassador, QtOnPi Device Program member and have published several Qt applications for Maemo, Meego, Symbian and Playbook. I would like to port them to Qt5.
  12. meenotes, weather by Luís Gabriel Lima (luisgabriel) - I'm a software developer at INdT working mainly with QtQuick. I've a strong interest in test the QtQuick 2 & SceneGraph performance on mobile devices. Currently I'm working on the UiHelpers Playground project and the QtQuickStyles research project. I'm also working with the Plama/KDE community to port Plasma's GraphicsView-based widgets to QML. Profiles: ohloh, gerrit (Qt), QtDevNet.
    • "Permission denied" when trying to access meenotes]. Also, do you have screenshots or user feedback or... ? You are working on very interesting libraries, any indication on the direct benefits for mobile is welcome.--qgil 21:48, 30 May 2012 (UTC)
    • Fixed the meenotes page permission and the image urls, sorry about that. Regarding the libraries, the UiHelpers is basically a set of uselful Qt classes that depends on QtWidgets and we moved it to the UiHelpers repo removing the QtWidgets dependency. In some cases we also did a QML API for these classes. For example the Undo Framework, besides remove all QtWidgets dependecy we made a new QML API for it, allowing QtQuick developers (mobile included) to take advantage of this very useful framework using a QML-friendly API. The QtQuickStyles is an experiment that aims to be a general styling library for Qt 5, for now we're focusing on the desktop use case, but we're taking into account our experience developing the qt-compoments for MeeGo to do it in a way that in the future the solution will also include the mobile use case. --luisgabriel 4:30, 31 May 2012 (UTC)
  13. Graffiti by Abhishek Kumar (shwstppr) - Qt Ambassador, QtonPi member and author of some open-source Qt/QML apps - FlickrUp, CutePress,Shopper.
    • Graffiti is a cool applications, but how do you feel about developing a mobile UI on Qt 5? --qgil 21:56, 30 May 2012 (UTC)
    • For start I'll try to port only the drawing part, maybe with different colors for different users. Chat can be handled later with a separate view with an option to switch between them. I've tried QmlCanvas for that but it doesn't wor smooth with mobile devices as of now. I'll try to port the code I used while porting drawing part of Pencil for mobile devices which can be found here Kalakari. I can try to make some UI mock ups but currently I'm out of station so will try to show them if time allows --shwstppr 08:01, 31 May 2012 (UTC)
  14. Turpial, by Andrea Stagi (4ndreaSt4gi) - Turpial is a popular Twitter and Identica client for GNU/Linux that allows you to manage more than one account at the same time and access to a lot of features ( media support that allows you to show photos, watch videos from youtube, access foursquare and so on within the client, upload photos and use all the existing shortner url services ). The actual version is Turpial 2.0, it's in beta and supports Qt, and now we are working to port it on every mobile platform (actually is under development only for Android devices). As a memeber of the development team, I plan to port Turpial to Qt 5, also working on a synchronization system of the accounts and preferences between devices. I'm an experienced Qt developer, using Qt at work since 2009 and involved in other open source projects that support Qt (I am one of the authors of Emesene and contribute to TortoiseHG with patches sometimes).
  15. Move PDF Reader, by Naser (TheHost) - Move Reader is a new animated way of reading pdf Documents on mobile devices without the need to keep moving the view window and zooming in and out all the time.(Under Construction) + Qt Ambassador, QtonPi member, Inventor and Graduate student.
  16. Vovoid VSXu, by Dinesh Manajipet (saidinesh5) - VSXu is basically a modular OpenGL programming environment, mainly used for creating music visualizations, VJing and demoscene projects so far (http://www.youtube.com/watch?v=ktkS7A5CZ8g). We already had an Initial port of VSXu to OpenGL ES.(Tested on the N900 http://vimeo.com/20404897 - and waiting to be tested on Raspberrypi). Also, the upcoming "sensors" module ( http://bit.ly/KVHBNA )in VSXu can make use of the local sensors (if available) and remote sensors of another device (via. a Qt Client which sends the sensor data Wifi) to control various parameters and transitions of VSXu visuals. I am just another KDE contributor and one of the developers of VSXu. (http://wiki.qt-project.org/User:Saidinesh5 )
  17. Mash - Mobile Yammer client for N9/N950, by Saija Eteläniemi (matrixx) - The Yammer client is mostly created using QML, so it would be a point of interest for me to port it to use Qt5. In addition, I've been working on several projects for Harmattan: my stuff on github, which also uses QML and Qt components and would be fun to port. I'm Also participating in QtonPi program, a Qt Ambassador and a certified Qt Specialist. As a device preference, N9.
  18. Bord, by Trismer (trismer) - We are experienced QT/QML developers, with different applications for MeeGo/Symbian devices. We are very active in testing new Qt platforms, like necessitas, RaspberryPi, Blackberry (http://trismer.com/portfolio/qt-on-blackberry-playbook/). We are very keen to test Qt 5 on N9 and other smartphones with our current and upcoming applications.
  19. Tinger Calc, by Zeyu Pan - Tinger Calc is a powerful scientific calculator environment. It supports elementary math ( +, -, *, /, ^), trigonometric functions (sin, sinh, asin, cos, cosh, acos, tan, tanh, atan), exponential functions (exp, ln, lg, sqrt), math constants (pi, e), system functions (exit, quit, print). You can use keyboard or system input method to enter equations, and then click "Ok" to calculate results. In addition, you can use the "=" symbol to remember your temporarily value, such as "x = sin(pi/4)". Website: http://tingercalc.sourceforge.net/. Nokia store: http://store.ovi.com/content/254303. I'm also participating in QtonPi program, a Qt Ambassador. I am very glad to port "Tinger Calc" to Maemo platform using Qt5.

  6. Qt5 on Mer timoph Qt project profile.Going to work on porting Qt4 applications and writing new ones to help test Qt5 on Mer (Qt5 will already be partly included in the next Mer release). Will start with something simple - making a bit fancier version of the Yatzy game I recently wrote using Qt4/qml and some other existing things such as Qt flying bus, same game and planning poker cards.
    • Here goes a bit of support to Qt 5 integration and optimization in Mer. Please specify in your entry the other applications you are referring to.--qgil 21:52, 30 May 2012 (UTC)
  7. Puzzle Master, by Timur Kristóf (Venemo) - I'm mostly interested in experimenting with Qt Quick 2, including the deep C++ level. Considering that my app contains lots of custom-written QDeclarativeItem code with non-rectangular items, it would be nice to see how Qt 5 can cope with it. I'd like to port my app over to the Qt Quick 2 API, rebasing my code on top of QQuickPaintedItem and seek out other possible improvements with exciting new stuff such as QML shader effects. here is the source code and the Nokia Store link. I also wish to take a brief look at how Components would work on top of Qt 5. (Note: Because I participated in last year's device program too, I'm only applying for an N9. Don't want to deprive anyone of an N950. Note 2: I may apply at the other category too.)

Declined

  1. CMake (cross compiling with Qt 5) by Stephen Kelly (steveire) - Qt maintainer, KDE developer and Qt based library developer.
    • Although an interesting project, it doesn't really fit in the original purpose of this activity. Doesn't really help showcasing Qt 5, or directly testing it before release. Thank you for your understanding.--qgil 18:02, 30 May 2012 (UTC)
  2. Some free apps on Qt-apps, by Manoj Agrawal (manoj) - Nokia Certified Qt Specialist, Qt Ambassador and QtOnPi member. Created many complex GUI applications and Qt widgets on desktop and embedded systems. Also created a App Store kind of trial application for one client who proposed it to Nokia.
    • Qt Widgets applications are in fact out of scope in this Qt 5 Mobile Projects activity. Already in Harmattan QWidget was not supported.--qgil 20:53, 30 May 2012 (UTC)
  3. Tutorials and Docs, by Johan Thelin (e8johan) - Qt5 and QML needs to be documented for it to gain a larger audience. I'm willing to do this.
    • This is an interesting area of contribution but fall out of the scope of this activity. Please reach me via email to know what do you have in mind. Thanks!--qgil 20:58, 30 May 2012 (UTC)
