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 :( ;)

[edit] but – as a consolation – have a look on the Qt-related wikipedia category [en.wikipedia.org]

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)

Not enough.
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.

we’re hoping to see QT move to supporting various tablets, otherwise i see more C++ with HTML 5, javascript, jquery development for UI dev
