Hi Stefan, I followed your instructions and explored the LiveWire tool, which helped me understand how it leverages ContourModelLiveWireInteractor for various interactions. I also reviewed its corresponding state machine and configuration XML files, which were quite easy to follow.
Next, I traced the inheritance hierarchy of ContourModelLiveWireInteractor up to DataInteractor, where each class has a ConnectActionsAndFunctions function responsible for linking state machine actions to interactor functions (as you mentioned in an earlier response). The description of the DataInteractor class also states that new interactor classes can be derived from it. >From this point, what would you recommend as my next step? Should I proceed with creating a new interactor and its associated XML files, or is there anything else I should refer to before diving into the implementation? Looking forward to your guidance.
