I’m working on some new software, and I’m trying to make it as modular

  • 0

I’m working on some new software, and I’m trying to make it as modular as possible. I have been coding for a while..but I lack some key principles which I am learning as I go along.

In trying to make my current project modular, I am using the model-view-controller architecture. In designing my application, I have found certain things I am unsure of. So I come to you…

I’ll give you some information which may be useful:

  • I am developing this application in Qt.
  • It is a desktop application.
  • Single user, so it is not very complicated

My questions are:

  1. When implementing the various modules(models, views etc..) and all
    of the classes associated with them, should I be initializing
    modules within modules? Should I create a ‘model’ instance within a
    ‘controller’, or should I create everything in ‘MAIN’ and simply
    pass the modules as references?

  2. My strategy is to separate my application into many MVC bundles.
    Each one will follow the basic principles: model gets the data, view
    displays it, and controller takes care of all interactions between
    model-view, and performs all required logic. Is this correct?

I appreciate all of your help.

Thanks.

    Should I create a ‘model’ instance within a ‘controller’, or should I create everything in ‘MAIN’ and simply pass the modules as references?

    Pass the modules as references. I don’t know if Qt has the concept of packages within a bundle, but in Java, I have separate packages for the model and the view.

    My strategy is to separate my application into many MVC bundles. Each one will follow the basic principles: model gets the data, view displays it, and controller takes care of all interactions between model-view, and performs all required logic. Is this correct?

    Yes, that’s correct MVC principles.

    Sometimes in a more complicated application, your application view might consist of the GUI (a view) and a model of the GUI (a model). In this case, the application model, which is probably a database access model, interacts with the GUI model. The controller for both the GUI and the application is driven by the actions of the user.
