Solved How can I expose a C++ function to a QJSEngine javascript enviroment?

[SqushiBune]

If I have a C++ function that I want to be callable from javascript how do I add it to the enviroment, I only see functions for adding variables to the enviroment?

What I am doing cant be done with a variable, the C++ function will write to device files in /dev to send data over a serial port.

I have checked here:
QJSValue
QJSEngine

@SqushiBune
Are you bound to QJSEngine?
If so see this.

But i suggest you to use QQmlEngine (also derives QJSEngine) and use:

QObject* myObj;
QQmlEngine engine;
engine.rootContext()->setContextProperty("$MyObj", myObj)

Anyway the method needs to be callable on the QObject, which means it either must be declared with Q_INVOKABLE or declared as slot.
