[Flashcoders] MVC(S) Question
Hi, I am reworking an application we use for a touchscreen interface and am trying to design the architecture for all the right reasons. I am currently wrangled in MVC-ness and trying to work out the best way to move forward. Having immersed myself in many books and texts, I still find myself going around in circles some of the time and would like to make some choices with possible help from you guys... The app talks to a back end control system via an XML socket. The system has a number of devices attached and the screen controls allow for changing stuff on the devices and monitoring them too along with the application navigation, etc. Requirements: It be easy to add new screens later on. The coupling of component interaction to back end needs to be fairly fast - we use sliders and trackpads to move devices in real-ish time. The application may use different languages which affect text and content. My screens are essentially composite views or possibly composites of views - one screen may have controls that interact with more than one device. I am trying to decide about arrangment of my Models Views and Controllers. Essentially my components will be grouped into Views, but I do not know whether it is a good or bad idea to mix controls for different devices within a single view. Also, is it better to have a single controller responding to messages from all views to route these to the appropriate model, or should I create a controller for each view. I am thinking the latter would be overkill possibly, but I am still not sure whether to create a composite of controllers, or separate them, use simple commands and some kind of factory / lookup, etc. - some component events will be routed to devices, some to the application, etc. At the other side of the controller, my models will be for instances of devices and will send updates to the backend other bits of the app. Is it better here to send these updates directly to all the views or a controller(s), or is this choice affected by others above? The other question is, do I lever the existing Flash event mechanism for communications across the app, or will this slow it down - is it better to use basic observer for the model updating other things??? I have looked at a number of frameworks and the idea of PureMVC with it's very loosely coupled elements seems very sensible. As most of the frameworks are constraining in some way and I need the experience, I am hedging towards designing my own framework here to fit in with the requirements above - mainly, getting component interaction to the back end as fast as possible. In the current AS1 functional type code the button onRelease, etc. functions are pretty much wired directly to sending of data over the wire. Whilst this is good (fast), the maintainability of the project is not. Different wiring, change to spec's, etc. the bits I am trying to clean up along with porting to AS3 / AVM2. Does anyone have any advice here particularly with regard as to how to layout my MVC'ness - can I enclose entire MVC elements within another M, V or C, or do I nest M-in-M, etc??? Thanks in advance.

Re: [Flashcoders] MVC(S) Question
Hi Glen. I would defenitively go with lose coupling and one controller by one device. You mentioned one requirement being the scaleability what new views are concerned - so there is no others choice. To proof the speed of that setup you need to implement a prototype of a likely application state. How should someone else know? But as a general tip: Always go with the better architecture - the speed comes with better hardware (or flash player).

The best thing to do with this is to create a MovieClip the size of the thing to print and put a Bitmap inside it. Do a grab of your Receipt table / MovieClip into the bitmap and use the PrintJob to print - this gets around problems with vector vs bitmap in printing because you are always printing a bitmap. As long as you have a way of laying out your receipt you can print it from AS if you like...

Maybe mask the stream area out. Start each letter at x -

create

Loop through the array each timer increasing the x position of

Re: [Flashcoders] MVC(S) Question
Dr. Ache, This isn't about your advice on the app, as I think you are right with regard to his situation (I am just starting to get better with real oop so don't quote me); yet, it is the comment, that you should always use loose coupling, that gets me. Doesn't tight coupling use less cycles and memory since you don't need so many listeners? Are not event listeners are essentially loops that test for a change in a variable on a consistent basis? What if an app had to run on a Pentium 633 (my old pc) and it had a hundred listeners? I have been in and watched lectures and read papers where the big boys of scientific computing/mainframe/webapps (IBM/Google/Yahoo) try to get their gigantic applications as tight as possible when speed is a real concern. They say that you should use tight coupling whenever you can get away with it and speed is the real goal; yet, loose coupling when primary concern is scalability; however, they always say a balance between the two makes for better applications. Again I state I am just starting to get involved in this argument, so I hope I will be forgiven if I am talking out my backside. Waiting to flamed, Anthony dr.ache wrote: Hi Glen.

Re: [Flashcoders] MVC(S) Question
Hi Anthony. Thats the point. When it really comes to hard performance issues, eg. games or other extrem algorithms, you cannot go without coding more coupled. But as I said: Build (and build it with good coding styles) a prototype of the app where you expect to have the bottleneck in terms of performance. But only then optimize that part of code and keep everything else in shape, meaning good oop style architecture... there are only small parts of the entire system that need to run as fast as possible. And when you have coded right that part is a module of the system (which you can then test in isolation).. And events do NOT check a variable in a loop. The complete opposite is true. They only occur when something happens, like a mouseclick or another state change when you setup an individual event. Sure, when you fire an event when a variable changes and you change the variable every frame... :-) but that should not happen :) And this loose coupling thing is just an idea, a thing you should strive for... but there are enough situations in which lose coupling is neither the best way nor possible. I do recomment you Head First Design Pattern if you are interested in this topic. Its not the newest but still very intuitive and funny(in a good way) to read.
