Dynamically add functions to C++ objects exposed to JS
I have an ID and a type representing some Object O of type T in my application. I do not have direct access to this object. I only have its ID. I however want to expose this object to JS. I cannot create "normal" QObject wrappers for each of the classes I need to exposed with Q_INVOKABLE methods because:
available methods are numerous and may be changing a lot in the future; So, if I need to write QObject wrappers, I will spend all my time (and maybe more) maintaining them;
Objects are potentially heavy and copying them here and there is costly.
Instead, I can retrieve the list of prototypes attached to each classes I need to expose to JS. So, what I want to do:
From ID, retrieve the list of functions prototypes attached to this object;
Dynamically attach these functions to a QObject (or similar); each function should call some global function.
Pass this object to the JS engine and use it.
At that point, I would be ok.
Is it at least a good idea? If yes, how can I dynamically attach methods to newly created objects and pass them to the JS engine?
Thanks for any help.
