[Poll] What percentage of your development is Qt related?
I spend my "development hours" between .Net/C#, Java, MS C++ and Qt. Sometimes I get to code on all of them in a single day :)
At this time, all my Qt applications are distributed for free and target the maemo platform. I hope to expand and try to move Qt development to the top of the list.
How do you split your time?
I write applications only on Qt now.
Now i have only one project for the university and of course is based on Qt :)
For me it's roughly 50-75%. I include "development" of sql data models and business logic design into that count too. For the rest of the time it's Java and some other C++ (which is not really Qt based, but we use Qt there too for some basic things like strings and XML)
I'm afraid, it's only about 25% currently. The rest is pure C++ with bost and STL (sometimes COM) service components (the clients are MFC and VB). I hope it will get more Qt in future...
I want to switch my every-day project to Qt, but my every-day work inhibits me from doing so :( ;)
 but - as a consolation - have a look on the "Qt-related wikipedia category":http://en.wikipedia.org/wiki/Category:Software_that_uses_Qt
For me it is something like 90% now, but it always changes for me (4 years ago it was near 90%, 2 years ago it was something like 30% of Qt, now it is again 90%). I hope it will not go down again :)
:) Denis, for what target platform do you develop with Qt?
Wolf P., for now it is mobile platforms: symbian, winmo, meego, android. But used to develop for desktop platforms in past (linux, windows, macos) and even for non-x86 architectures :) (sparc architecture).
:) thx for the info
I hope it will get more percent.
I'd say about 30% of my projects are coded in Qt based code, about 50% are coded in C/C++ (mostly libraries) and about 10% are done using Java. The remaining 10% are a chaotic bucket full of scripts and exotic stuff (like COBOL...).
For me its almost 90% in Qt now, a recent change anyways. Say 1.5 yrs ago it was 100% Java
I'm focusing on Qt exclusively for personal/freelance stuff, but my day job has me doing Delphi (which is impressive in it's own right)
I work with banks related software, so more and more Java then C++
we're just starting to port to QT for UI support, but I don't see the overall project ever consuming QT more than 25%, possibly the majority of work will be core C++ and something like 10% will be QT effort in the grand scheme of things. obvious it's going to be 90% of the time during the porting phase of our UI to QT then I see 100% core C++ refactoring, and ongoing redesign.
pretty much 100% of the things I write on my own time are Qt but job has me writing python, shell scripts, etc. in addition to Qt.
About 75%, the other part is C/C++ OpenCL parallel software.
When I first answered the poll, it was still 75%+. Now, it is considerably less, as the current product I work on has only the UI done with Qt, and even that is going though an abstraction layer.
I do around 90% development on Java EE 6 for highly scalable systems that use mostly desktop and web applications for client interaction (very little mobile requirements yet).
I use Qt 10% of the time, and mostly experimenting on what it would take for me to do the same things in Qt that I currently do in Java, too bad that C++ libraries are still lacking compared to what I do on Java EE (currently I use it for automotive and banking).
I found some replacements for the distributed, highly scalable parts of the systems (ZeroC ICE products, but it's GPL or commercial and quite expensive, and Oracle GlassFish is a lot more flexible licensed), but for deployment and Web communications, still no luck (would be cool to have a good fastcgi or scgi implementation in Qt, I tried some opensource projects but are very old or lacking basic functionality).
Object serialization has really improved in Qt, with QObjects and XML you can go really far, and for Qt5 there's a new serialization module for supporting JSON as well, but still, I think to make it as easy as JAXB in Java, it would take some time and dedication, but with QML stealing all the trolls attention, it's going to be hard to go there anytime soon.
For the desktop client side, Qt is really on top of Java swing, but, there are A LOT of components, both open source and commercial for swing, which Qt is lacking, i.e. a diagramming component, a very-rich-eye-candy charting, an iCal/Outlook like calendar component, a MS Project like gantt/scheduler component (more modern looking, I've seen KDABs and it looks like made in the windows 3.11 days), or text visual diff component (something like that would be useful in Qt, specially for Qt Creator that still has text only diff).
'im working in Qt only ...
I am certified in Delphi and VB, but I do not remember them anymore, now it's only Qt
[quote author="Vass" date="1294323868"]I write applications only on Qt now.[/quote]
All my serious projects are based on C++/Qt or PyQt, for the rest, ie. quick test scripts, I use Python + standard libraries.
I am also working on Qt only , previously worked on C# and ASP.NET , Also a certified MCTS (Application Development Foundation 2.0) and MCTS (ASP.NET Application Development 3.5) n now looking forward for Qt certification.
Its about 40%
the other parts is maintaining projects on VB and C#
but now we are focusing on multiplatform projects, and i think the Qt percentage will be grow.
About 50 % of time I spend on Qt development.
75% of my C/C++ programming is QT related and 25% is SDL related :)
We use 90% of C++/Qt/QML and 10% of Boost.
Less than 10% (only for personal projects). Unfortunately that means that my Qt learning is slow going.
But again, it depends. Half a year ago I was working 100% only with Qt.
Currently I'm mostly using C# ( Mono) and asp.net and a lot of SQL. From time to time php and Java if I really have to.
Currently I'm using Qt only for personal projects.
I would say 80-90% developing in Qt...
90%. When I find code examples that aren't Qt and I don't want to use them for web development, I always start the process of converting the code to use pure Qt. The only other development I do is occasional html/java/php development on websites.
Most of my development is in Qt. The rest is a collection of languages ( Assembly, C, and some Common Lisp).
I work as a developer, using Qt. But after work, I'm a webdesigner/creator as well. So there goes some time in as well. (HTML, CSS, PHP, ...)
