ADR Suggestion, GUI and Backend integration

[AndrewSazonov]

GUI

• Written in QML
• GUI should ALWAYS access all domain specific logic from the BackendWrapper
• GUI should ALWAYS access domain specific data from the BackendWrapper, NEVER fetch any data directly from the backend

BackendWrapper

• Single "contact-point" between the GUI and each of the given backend
• Interface definition to make the GUI backend agnostic
• Located in Gui/Globals
• Wraps (maps) ALL properties and functions needed by the GUI to corresponding parts in the backend
• Dedicated QML object serving to wrap the backend API and provide a switch between backends
  • All properties are readonly
  • Setter functions to handle user interactions
  • Methods to trigger Backend functionality
• Enables the QT Create IDE to provide help when coding the GUI

Backends

• Folder with two or more backends
  • Mock backend with dummy functionality only serving to ease development of GUI (QML)
  • Python backend to expose real logic to QML
• The different backend MUST have an API that satisfies the BackendWrapper requirements for properties and methods
