data passing between many views

[Vymmiatacz]

In my application I'm trying to utilize MVC architecture. I have two views (Main and Settings), every single view has own Container.

I would like to pass pointer from 'Main' to the newly activated 'Settings' view - but how ?
According to the following method signature, the only thing I can pass is a descriptor.

ActivateLocalViewL(const TVwsViewId& aViewId,
TUid aCustomMessageId,const TDesC8& aCustomMessage)

This is not enough for me. What should I do?

If the Settings view needs a pointer to the model it can get it from the controller (*AppUI), either at construction time (parameter) or at activation time (query the controller)

Ok, let's assume that I will move all the crucial objects with theirs datas into MyApplicationAppUI class. But how can I access them from views? I tried to use AppUi() method, but this method returns pointer to generic interface CAknViewAppUi, which is another view, not the controller...
I cannot see my objects thru pointer to CAknViewAppUi.

How about some casting?

And since you want to implement MVC pattern you should separate the M from C and then passing the M to V at construction time would make more sense and would be a piece of pie to implement.

Probably you got right.
It seems to me not very elegant solution, but for sure, working and "cheapest" one.
