QtCon Opens In Berlin (qtcon.org)
Long-time Slashdot reader JRiddell writes: A unique coming together of open source communities is happening in Berlin over the next week. QtCon brings together KDE, Qt, VLC and FSF-E to discuss free software, open development, community management and proprietary coding. Live streams of many of the talks are available now. The opening keynote spoke of open data and collaborative coding freeing accessibility information. 13 tracks of talks cover Community, Web, Best practices, Automotive, Mobile and Embedded, Let's talk business, Tooling, QtQuick, Multithreading, OpenGL and 3D.
Check out this list of mostly obscure and unknown software that uses Qt.
You have a KDE which of course uses it. A few things built for KDE. And some hodgepodge apps and several unknown apps.

Qt has been in development almost 25 years. That is a pretty long period of time to have not evolved to something potentially mainstreamable.
I'm sorry, but I really don't like QT. It's not C++ - they have their own little language that compiles to C++ using an external compiler. It has crappy alternatives for everything in STL that work just slightly different but not any better. It has copy-on-write. It doesn't use inheritance, but gives you endless lists of almost-identical function calls (all those functions to add controls, for example). And that stupid Q everywhere you look is just painful.
