FLTK mentions (2)

  • declarative GUI libraries
    It’s not declarative, but small, cross platform, old school C++, and has a graphical UI designer that writes the C++ code for you. Since you mentioned Rust, it has Rust bindings too: http://fltk.org . It has different schemes that make it look more modern than the default scheme…. Source: almost 2 years ago
