  • 5. Browser r Controlle How MVC works Model View
  • 6. Typical steps1.  The user interacts with the user interface in some way.2.  The controller handles the input and converts the event into user action, understandable for the model.3.  The controller notifies the model of the user action, possibly resulting in a change in the models state.4.  A view queries the model in order to generate an appropriate user interface.5.  The view gets its own data from the model6.  The user interface waits for further user interactions, which restarts the cycle.
