ReflectionUtil.rtf includes:

inspecting an Object internally

• returning the public instance properties/methods of an Object.
• copying/duplicating public instance properties between Objects.

inspecting an Object type

• checking whether two Objects are the same type
• checking whether an Object extends another

MVC without Observer is like NATO without formal delegates. You’d let every citizen in every nation contact every other directly.

We want our model to publish to a group of subscribers. Flex bindings can pull this off. Consider, however:

1. Encapsulation recommends, and modularization implies, that not every class directly accesses every other. (Beware of EventBroadcaster use & Singleton abuse.)
2. While you have a handful of models with a slew of listeners, EventListeners are firing constantly, listening for changes. This will affect memory consumption.

Observer allows for an easily-readable, encapsulated, relationship between Model and View. Your model extends a Publisher class. Publisher has a function which adds subscribers to its subscriber Array. The Publisher class also has a function to notify its group of subscribers. The Publisher knows that any Object which subscribes will implement the Subscriber class.

Views which require Model/Publisher data extend a Subscriber class. The parent Subscriber is a good place to declare your static constant strings — these describe data groups. (Having these outside the model better supports encapsulation, but I’ve seen them in the model in other examples.) Each Subscriber child has an Array which notes the data groups the Subscriber is interested in. Each Subscriber has an update function which is called by the Publisher when it sends data.

A third class keeps things organized and readable. It’s there you subscribe the Views to their Model or Models.

I searched for similar AS3 Observer implementation examples online and found but one. Hope my example helps your code find its way.

Please stop lying. Guiliani made points about Obama’s experience, and his argument there was on solid footing. Then he said:

Look at just one example in a lifetime of principled stands – John McCain’s support for the troop surge in Iraq. The Democratic Party had given up on Iraq. And I believe, ladies and gentlemen, that when they gave up on Iraq they were giving up on America. The Democratic leader in the Senate said so: “America has lost.” Well, if America lost, who won? Al-Qaida? Bin Laden? In the single biggest policy decision of this election, John McCain got it right and Barack Obama got it wrong. . . . full speech

Bush told us Iraq had weapons of mass destruction. He was wrong. Ever since then, our Republican Party shouts Al-Qaida/Bin Laden and Iraq in the same breath. There is no connection. Al-Qaida/Bin Laden were sheltered in a completely different country called Afghanistan.

It’s easy to prey upon American’s weak education system, its overworked class is too busy to remember what Bush told it last week. Have some moral character, though. Admit you’re wrong. Admit our leaders will send people to die if it fills their pocketbooks. You say you believe in Hell but you act like you can outrun it.

What I’m getting to is that these guys are hot. What floored me was their audience of Indy hipster kids. Either something revolutionary is tuning the tastes of the cool kids or else it’s just that Hawk & Hacksaw’s singer used to be in an Indy rock group. No matter. Hawk and a Hacksaw pounded down all the fierce, instinctive rhythms. And the throngs began hopping, clogging, clapping. I want my tribe, clan, and small army. I want it back from The Man.

and i fell in love with iorek when he looked at lyra all funnily and said in his sexy hart hart booming voice: you want to ride me? i go faster without armor.

and in my heart, i was mumbling under my breath: yes, i want to ride you! god, get rid of that damn armor then! let me ride you, iorek! i want to ride you!

iorek byrnison is the handsomest polar bear i ever did see and i know when i saw aslan, i said i was going to marry a lion even if it kills me. well, no more. i’m going to marry a polar bear. i will marry a polar bear even if i freeze to death!

have always used as2 on an as-needed basis, but decided this time to operate on it.  open it up. see how it works.  or doesn’t work. dragged as2 screaming into the year 2008. into the light.

the utility classes i found, modified, or extended are useful for anyone coming from an object-oriented background:

• DocumentUtil allows you to specify a Document class (aka Main class). :: Ryan Taylor @ boostworthy.com
• BezierTween creates beziers using little phrases that even Flash 7 can compile. :: Felix Turner @ airtightinteractive.com
• MovieClipBubbler bubbles as2 MC events. it is not simpler to use than an Event Broadcaster.  it does have performance benefits over an Event Broadcaster. :: Ralf Bokelberg @ helpqlodhelp.com
• Hitbox is an essential extension of MovieClipBubbler, at least in concept.  you should take my implementation and twist it to your ends.  using Hitbox avoids having to draw zero-alpha’d Hit areas on all your MovieClips.  in simplest execution, the MovieClip in your Library links to Hitbox (rt-click/Linkage/’Export for ActionScript’/Base Class).

• Pre-Moxie workspaces will act irreverant. Import all old projects into a fresh workspace.
• When your project clearly isn’t building, turn off “Project/Properties/Flex Compiler/Generate HTML wrapper file.” Then click “Apply” and turn it on again. Sometimes it works. Other times you need to make a new Project.

Not bugs but some tips to save you time:

1. When drawing shapes programmatically: create a UIComponent rather than a Shape, Sprite, or something else that you’d think would work.
2. this:
   • var loader:Loader = new Loader();
     var url:URLRequest = new URLRequest("http://www.helpexamples.com/flash/images/image1.jpg");
     loader.load(url);
     this.rawChildren.addChild(loader);

   is not as correct as this:

   • var loader:Image = new Image();
     loader.load("http://www.helpexamples.com/flash/images/image1.jpg");
     this.addChild(loader);

Skinning the MenuBar points:

1. You can apply styles for the submenu to Menu, including borderSkin, fontSize, paddingLeft, and now in build 187191 if openDuration=0, you can skin showEffect.
2. The submenu doesn’t exist until activated from the MenuBar.
   myMenuBar.addEventListener(MenuEvent.MENU_SHOW, setSubMenuProperties);

   You can then alter additional properties and add filters, masks, …

3. If your user group is expecting MenuBar RollOver to show the menu, you must play Houdini. Listen to anyone having a MOUSE_OVER:
   • menubar.getChildAt(j).addEventListener(MouseEvent.MOUSE_OVER, menuItemRollover);

   Redirect the event:

   • e.target.dispatchEvent(new MouseEvent(MouseEvent.MOUSE_DOWN));
