ActionScript 3 :: Alternatives For Registering Events On Stage?
Feb 1, 2010
I am programming a little software prototype as Flash/Actionscript3 application. Currently I registered some Events on stage - but it is cumbersome since stopPropoagation() needs to be used all the time. As Example: I am having a element shown via mouseclick would and a event for closing the menu on stage. Without using stopPropagation, the menu opens and closes again immediately. The hide-function is registered on some objects so just checking if target= stage would not do it, unfortunately.

I changed them all to mouse events (I was told mouse events would still work on an iPad) and without doing anything else (just changing them to mouse events) the app started to function in testing. But then I transferred it to my iPad and it didn't work. At all. It didn't do anything.

I have some code where there are 3 objects on the screen and i want it to highlight them in orange when you mouse over them, and when you click on one to select it, it highlights it in yellow.
to do this, im registering a roll_over, roll_out, and click event but for some reason it seems like all i am getting is the roll_over event.
Something strange is that in the code below i only ever seem to get roll_over events but if i only register the click event instead of all 3, i get the click event. It seems like the 3 events are somehow conflicting or something :/
You can also see an example of what im talking about at:

click play to get to the screen where this problem is.
ActionScript Code:
package
{
import flash.display.*;

I noticed that the Object.watch and Object.unwatch methods are gone in actionscript 3.
I've tried to find alternatives but the event system doesn't dispatch events when properties change, There is a data binding system but I think that's just for Flex.
Does anyone know what (if any) the alternative is?

I'm building an object oriented project with liquid layout in a loose MVC framework. My controller knows when the stage is resized, and it needs a way to tell all of the display objects to rearrange themselves appropriately when the stage resizes.
Option 1 would be extending the sprite class with a class that has one additional resize() function. On initializing the class it would register itself with the controller which would then noitfy all of the assets when it detects a stage resize.
Option 2 would be building some sort of global event that any child of the stage could listen for and do its thing when the event comes through.

Imagine that you have a lots and lots of the same library item on stage - movieclips - and you want each of them to be clickable. Normally, you would iterate through each of these and register an event listener on MouseEvent.CLICK for each one. It seems to me that if there are large quantities of these items this could be quite inefficient - on memory mostly - to have all these event listeners. I'm trying to figure out if there's a more "central" way to do this, where your main document class just registers once with some kind of central dispatcher using a custom event? Any time ANY of the movieclips are clicked, that fires this custom event and you can just query the event to figure out which clip was clicked.
Each movieclip that is clickable extends an AS class through its linkage, and when clicked, dispatches a custom event. If I'm using the IDE to put a lot of objects on stage, and these objects have linkages to their own custom classes, I don't want to ALSO have to go into the main document class and have it iterate through these objects to register event listeners on each one. I don't really want the document class to have that much knowledge about these objects (loose coupling). I'd rather the objects "communicate" through this mediator and not really worry about knowing more about each other than what you can access through the custom event.

i have a button on the stage (added manually) and its an instance of BtnStart called starter. but for some reason i cannot access this in the document class i.e. in the constructor (mainly because its not registered at that point). how can i use a stage button in the document class constructor?

I have an animation that I want to start when clicking on the flash window. However, I've also have some buttons on the stage. If I add an event listener for MouseEvent.CLICK on the stage, then it 'eats up' the events and the buttons don't work.
I've tried some tricks, by adding some invisible buttons on top of the real ones, and use the MOUSE_OVER event to selectively enable/disable the mouseEnabled flag for the stage, but didn't work because it complains that the property or method doesn't exist (which I find odd).

is it true that keyboard events can not be accessed outside of the stage on non display objects?
example:
package
{
//Imports
import flash.events.EventDispatcher;
import flash.events.KeyboardEvent;
[Code].....
here i would like to initialize a new TestClass() then press a on the keyboard to receive the output Test Class: a.

If there is movie clip playing on the stage is there a way to know if it is done playing. Is there some kind of stage listener or movie clip listener you could build that would monitor the clip that is playing and when it is done have the flash program do something else?[code]...

I have a small animation that moves based on the Y coordinate of the mouse. My client wants the animation to stop once you move your mouse off the Flash Movie. I've tried to explain that Flash does not listen for mouse events on the browser but they are pretty adamant.
So, I'm I'm just checking to see if anyone knows of any "non-javascript" ways to get flash to continue to get mouseY coordinates outside the flash movie. Or, at the very least, tell when the mouse has left the flash movie so that I can stop the animation.

I'm creating an AIR application that loads a child SWF. The child needs to read keyboard input (for a game), which I usually do by adding a keyboard event listener to the stage property, like this: stage.addEventListener(KeyboardEvent.KEY_UP, onKeyUp)
However, the child SWF is apparently not allowed to access the stage property because the parent SWF owns the stage, so I get a security sandbox violation. So I need to do one of two things:
Bypass the security restriction allowing AIR to load SWFs that have an absolute path (local path), and allow that child to access the stage, orGet keyboard events to be heard by some display object other than the stage, without ever calling "stage" (this includes stage.focus).A few things I have tried already: Security.allowDomain() does not work. AIR thows an error saying that allowDomain doesn't work in the AIR sandbox. Also, adding the keyboard listener to the child's document class (then clicking inside the SWF) doesn't work.

I have been trying to pick up more as3 lately, also have been converting some of my sites from as2 to as3. In as2 I could create 3 menu buttons and save them in a mc- lets call it menu_mc. This menu_mc sits on my main stage. I have also placed a mc on stage to hold anything that I load. Lets call it holder_mc. So I figured out how to get my email button to work using this:
email_mc.addEventListener(MouseEvent.CLICK, mailto);
function mailto(event:MouseEvent):void {
var email:URLRequest = new URLRequest("mailto:myemail@mail.com");
navigateToURL(email, "_blank");
}
That's fine. What I can't for the life of me figure out is understanding how to click on one of my menu buttons and load a swf into my holder_mc on stage. In as2 I could use this code on a button :
on (release) {
//load Movie Behavior
if(this.my_holder == Number(this.my_holder)){

I have a movie, which on the click of a button will load a child swf.
The child swf has code which adds events to the stage object.
the child also accesses properties such as stage.stageWidth
When the child is ran on it's own all is fine, though when it loads within the parent movie i receive the error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.at Home()
"Home()" is the name of the document class in the child SWF.
a) access the stage from a child swf
b) add events to the stage from a child swf

I am trying to capture mouse events in flash while the mouse is being held down. The intention is to keep reciving events as long as the mouse is pressed, even if the cursor leaves the flash element. That's the behavior I get on all browsers other than IE, which only fires events while the cursor is inside the stage.
I'm pretty sure I've seen such "well behaved" flash applets work in IE before.

Preferably something that integrates well with a Flex front end. Yes the Spring Security guys say this is possible, but all examples seem to use legacy jsp tag libraries making them half useless as examples.I don't want to spend a month setting up and learning how to use a security tool. I would like a tool which supports using annotations (@RolesAllowed etc), MINIMAL XML, and 'remember-me' features (not cookie based).Apache Shiro seems to support Flex/Silverlight/Swing as well but I'd like to know if there are any other alternatives that are NOT container specific.

handling global keyboard events in Flex, is to attach a listener in the application complete event of a Flex application. However, no matter what I try, I have not been able to catch events without clicking on a point on the page, which is hosting my Flex application.
Moreoever, if I use a Flex component in a web application, where there is also html and Javascript, I'd still like to be able to grap global keyboard events, even if the embedded flex component (in flash player) does not have focus. So is there a reliable method for connecting flex applications and components (when they're embedded in a web page) to keyboard events?

I'm looking at options for rendering PDFs on the server to avoid the user having to download them (they're big docs) and/or have a PDF reader installed and configured (audience is not tech savvy). The Google Viewer and Scribd are nice examples, but I'm not interested in making the PDFs available on the web (for Google) or storing them on another party's servers (Scribd).
My favorites right now are FlexPaper and PDFWebViewer.NET but I wanted to see if I'm missing any other options.Most of the related SO questions on this topic are somewhat dated, so maybe there's something new?

through out a very old complicated fla there are buttons which set variables using _global paths
such as:
function menu1_2(Event:MouseEvent) {
global.mode = "hide_hotbox";
MovieClip(this).gotoAndStop("stage_1_b");
}
How can I make the variable "hide_hotbox" and others like it accessible and changeable from any movie clip -- whether they be nested in other movie clips or on the main timeline, etc?
