Hi all,

Just wondering what you views are on where to place certain dialog boxes with a
typical MVC setup

A View, A Model, A Controllor

The model holds the data.
The controllor is only thing allowed to manipulate the model.
The view displays the model.
The view may have gui_models that wrap the real model so columns
in tables can get reordered but it cant touch the real model except
throught the controllor.

A button in the view labelled "Do something"
On click the view calls the controllor.doSomething()
Once the controllor has done its stuff manipulating the model
perhaps calls view->refresh()
Or perhaps the model tells an event manager "I've changed"
and the event manager tells the view->refresh()

Now thats all pretty straight forward.

What I have trouble deciding where to put is some dialog boxes
that interact with the user.

For example the "You have unsaved changes, do you wish to save ?"
type dialog.
You click the top right X, or choose exit or whatever.

Choice 1: dumb view
The view will have to tell the controllor "user requests exit"
The controllor must check if there are unsaved changes
if so the controllor must request the view->askUserToSave()
And depending on the answer, save the changes before exiting or not.

Choice 2: Intelligent view
The view checks to see if there are unsaved changes
If so it prompts the user "do you wish to save"
And then calls controllor->saveChanges(), controllor->exit()
or just controllor->exit()

Thanks for any comments
