For the past few months I have been working on a simple windows notepad like text editor. It’s nothing special, but when I first switched to linux I looked around and it took me a while to find leafpad. Unlike leafpad however, Janus uses gtk3, a much more modern toolkit then gtk2, it can display and modify binary data, and it can highlight code syntax for most popular languages. Feel free to check it out on the github.
This was mainly because I don’t know C++ but I do know C.
Outside of that, I generally sway more towards gtk apps then qt apps and I use Budgie, so it fits in with my desktop better. Gtk also seems to be more widely used than Qt on linux. And Qt seems to delegate more of its functionality to standalone libraries, which means more dependency tracking which I am very opposed to, whereas Gtk packages one library that encompasses most of the libraries functionality (although I don’t know enough about qt to be sure if this is the case).
