I started out using states, with the current state being bound to a property in the model (using Cairngorm.) Lately, as my application has dozens of screens and different users are privelaged to have certain screens at their disposal, I use a view stack (it's easier on the eyes to program, IMO), and have each state's viewhelper extended to register that given state as a screen object in an arraycollection of available screens. I also have a constants file of screen titles (my menu reflects the title of the current screen.)
I register each screen with its static title (pulled from the constants class), and fire off a custom cairngorm event when switching screens. e.g.: CairngormEventDispatcher.getInstance().dispatchEvent( new ScreenSwitchEvent(Constants.MainMenu)); Then I have a class that implements Command and have it do a search in the screen array for any object who's title is Constants.MainMenu. I've found this to be the best way, mainly because I rely on permissions and some screens have read-write access, some only have read, etc. For a smaller application, you could just use states and have a string property in the model called currentState that the currentState of your VBox is bound to. (I say VBox instead of application because I want a menu bar to be at the top of every screen, so the content is loaded into the vbox.) Then switching screens is as easy as calling: model.currentState = Constants.MainMenu Brennan --- In [email protected], "Sam Shrefler" <[EMAIL PROTECTED]> wrote: > > I'm just looking for an theory overview / suggestions on how to handle > multiple screens with nothing in common: > > For example, i have an application that I'd like to have a menubar on every > single screen. > After that, i'd have say 5 - 20 totally unrelated screens each with their > own display and function. > I see on each of those screens where viewStates would come in handy. > > My question is: > > Should I make viewStates for every single screen, or would using a viewStack > be better?
