The first thing to mention is that lablqml (previously known as lablqt) does not provide "bindings" as people usually understand it. It started as a set of bindings, but that did not work very well: is not very easy to generate code for all the widgets, and the result would not be convenient (in a word: too much inheritance in Qt widgets).
When Qt5 was released, Qt Widgets were claimed obsolete, and a modern approach for declarative GUI was recommended. It uses QML markup to declare GUI, ECMAscript to script GUI-related actions, and C++ to implement speed-sensitive business logic.
In its current state, I think that lablqml can be used to replace C++ by OCaml in small applications. In large GUI applications, we would probably still need to implement some GUI controls in compilable language (like C++). My library doesn't allow implementing these controls in OCaml at the moment. Once we get a better idea of the use-cases where controls are needed, I'm going to improve the library. Maybe you should pick some big GUI project and rewrite the GUI for it?
N.B.You need Qt5(>=5.2.0) to compile. Please, be sure that dev packages are installed too.
