I built this today and thought, that I'd like to share.
Qt 4.7 code editor (X5000 project)It is the simplest code editor, you can create in Qt 4.7, and it has been written, built and tested on my sparkly new X5000.
If anyone have ideas for further improvement, I am more than happy to hear. If you want to build it for yourself, I can definitely be of assistance. And if you want to try, but don't want to hazzle with compilers, then I can send you a readymade executable. Just remember, you need to install Qt 4.7 as well.
If you have comments, please keep in mind, that the goal is simplicity and if possible as few features as possible. I am not going to re-create your favorite code editor from another platform, rather I am going to supply you with the essentials of what you need.
Happy friday!
