Help with QML accessing C++

SPlatten

I am working on a very large project that uses a lot of QML and C++. Unfortunately and rather amazingly there is absolutely no documentation to back up the source code or design.

So I am in the very painful situation of having to work it out as I go along. I'm not that experience with QML. The QML uses references like vehilcle.data then accesses more information off that.

Can anyone help me to identify what to look for in the C++ that might help me track down what is being accessed? I also need to add more functionality and would like to implement a call to a C++ function, but until I can established where its coming from I can't really begin.

@JoeCFD , I found out today that there is some hidden magic that goes on in the application where a lot of the configuration occurs in another XML style file.

In my qml code I have

        Image {
            source:   generalSettings.wireConnectionState ? "/res/wireconnected" : "/res/wiredisconnected"
        }

generalSettings is an instance of C++ class GeneralSettings
wireConnectionState is a function of instance generalSettings which returns a bool

in your code it is likely vehicle is an instance of C++ class Vehicle and data is function of Vehicle

@JoeCFD , thank you, that makes sense, however i cannot see in the source I have where data is a function of vehicle.

@SPlatten Check if it inherits any other class.
