Most of the files are VectorCAST that has been brought back from Code Clinic. Look at the files but they are auto generated so they are mostly passing through.
This script is in the tests folder. The tests folder is not controlled in the way the Dialin files are controlled so I might go back and forth in between different tests. This is not affecting any of the Dialin features.
This is an exception that you have a view which you don't have access to its object but in general: whoever wants to use it to connect to a signal of another class should connect to that signal in its own scop/class and do it with its private slots. So in a case like this, these connections should be moved to the interface. But as I said it is an exception and there no better way than what has been done here.
