Page 10 mvc pattern figure

[hoseinz3]

in this figure why model connected to view ?

In classic MVC it's usual to pass the model to the view as a parameter (imagine passing a User model to the view). Without DTO's this couples the view to the model. The view has to know which methods and attributes the model has in order to render itself.

I hope it helps :)

@keyvanakbary it was acceptable for me that view depends on the model but I think that model never depends on the view.( in page 10 figure model depends on the view)

Hi @hoseinz3,

Initially MVC was used mainly for desktop GUIs. In those MVC implementations, the View was subscribed (through an Observer pattern) to Model changes. That's the reason why there's a relation between the Model and The View.

Hope it helps! Christian.
