ActionScript 3.0 :: Possible To Dispatch Events Across Packages?
Aug 25, 2009
I'm having problems with dispatching an Event across packages, I have a video player and when clicking the next button it dispatches an event to my EventManager class then I have another class in a different package listening for it but nothing executes the event listener.[code]...
I have two separate advancedDataGrid instances (let's call them A and B). What I'd like to do: when clicking on grid A. I'd like: for grid A to handle the click normally (i.e. default advancedDataGrid behavior) for grid B to receive a click event a certain location and handle such event using advancedDataGrid default behavior (i.e. without having to write a handler for such click).
I've managed to dispatchEvent a MouseEvent.CLICK to grid B and to handle such event by creating an event listener, but really I'd like for grid B to handle the event on its own (i.e. without having to re-rewrite a handler), and that doesn't seem to be the case. Is MouseEvent.CLICK even the right event?
I'm trying to manually dispatch events on a textfield so I can manipulate it indirectly via code (e.g. place cursor at a given set of x/y coordinates). However, my events seem to have no effect.[code]...
i have been trying to figure our the dispatchEvent system in as3. But am just not able to wrap my head around it. So can someone please explain and give me an example on how to dispatch custom events?
for eg: Here i just want to disptach event every 100ms and the event should give me the value of "a" .
I'm still trying to get my head around the best way to structure event flows. Someone made a lot of sense by telling me that contained objects should be decoupled from their parent containers so they're reusable between containers. Instead of calling their parent's function, they dispatch an event. Sensible! I recently myself in the awkward-feeling situation of dispatching an event on a contained object, from its parent. It seems more intuitive for an object to be the one dispatching its own events. Maybe I'm bordering on breaking the Law of Demeter? Example of what I'm doing: child.dispatchEvent(new ChildEvent(ChildEvent.IM_BEING_A_CHILD)); Am I correct in feeling strange here, or is it a normal thing for one object to dispatch another object's events?
So, events bubble up the display list. That's great if that's what you want. But what if you have objects on the stage that are not related that need to listen for events from each other? A simplified example:
var objA = new ObjA; addChild(objA); var objB = new ObjB;
[Code]....
Object B can listen for events dispatched by object C. But I also need object A to listen for events dispatched by object C. Also, these objects are created in different classes so I can't hard code references to each other.
I have an <mx:Application> which contains a <mx:Module>. This module has several child modules. It also has some an instance of a class I have created. I am trying to have a method of this class dispatch an event that can be "heard" by the module and handled. This isn't happening.To be more clear, I am using 'dispatchEvent' to from inside a class method.There is an instance of this class in: mx.core.Application.myapplication.mymodule.myclassIt is the 'myclass.somefunction' that dispatches the event. I have a listener registered in 'mymodule'. Nothing happens when the function/method runs, however.
It seems more efficient to store events on the dispatcher if they're never going to change. Isn't creating them costly? Is there some kind of information I'm losing if I dispatch an already-stored event?
I stumbled upon and interesting problem concerning spark's VideoDisplay-Component. It seems that it doesn't dispatch DoubleClick-Events. For better understanding look at the following code:
[Code]....
The Click-Event works for both components. But the DoubleClick-Event is only handled by the Panel-Component.
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?
Imagine you have a MC used as a container for several other MC's used as buttons.Now, should I use the class of the container to listen for and to dispatch events. OrShould I create a seperate class for each MC inside of the container to listen for and to dispatch events.
In summary: One class for all, or several smaller classes dedicated to their respective MC.How far should one go with abstraction?.
I am a novice in ActionScript 3.0. I am trying to use the sample code from AS 3.0 tutorial but it return me an error "Packages cannot be nested". How can I fix it? Here's the sample code: fla file format.
I want to set them up with packages but tried before and failed.At the moment, I've made a folder,
C:/flash/mbl
In there, I have all my classes that I want to reuse. what do I do next? I'm using Flash CS3, would also be useful to know how to do the same in Flex Builder 3.
I almost have it, ( I think) but whenever I try to use a package with more than one class in it -- even the standard ones supplied in the ActionScript references, they don't work.And, if I have anything in the flash file other than an empty single frame, it breaks. So this precludes the use of library objects, which, if you CAN use them, saves a lot of coding time..
In the Below action script file there is an error saying cannot import mx.controls.Label, I am compiling this through command line on,linux and the environment variable path is set where flex is installed ,how to resolve this
package { import mx.controls.Label; public class Test
how to get this to work. So I have 2 .as files (ImageMain and FullScreenImage)And in the fla file I have a movieclip on stage called menu and this fla is linked to the ImageMain.as
ImageMain.as (part of the code):
Code: package { import com.gfxcomplex.display.FullScreenImage; public class ImageMain extends Sprite { public static var menuIn:Number=-113;
[code]....
When I run the " red" code I get the next error:1120: Access of undefined property menu. It looks like the imported FullScreenImage.as cannot acces the menu movieclip on the stage.
I have made a script, and now has come the point when I need to use removechild. Whenever I try this I get an error. After looking at the problem, I think I need to learn more about scope and packages. I think if I put everything in the correct scope, I will be able to use the removechild command. I tried to make all my vars public, so that removechild would work, however I got an error that anything public needs to be in a package. I tried to add the package part to my script, but got the error that packages cant be nested. I tried some other things and still no luck, just more errors.
So, if anyone could point me to a tutorial, or recommend a book or something, that will help teach me about scope and packages, Or if you are feeling patient and generous, and you think you could explain this problem to a 5 year old, please explain it to me the way you would to said 5 year old. If you maybe think you can help me out on the script, it can be found here: [URL]
I'm brand new to AS 3.0, and I'm having a lot of trouble with it. Basically, all I want to do is load in an external swf when a button is clicked. The swf to be loaded would be defined by a variable, rather than hardcoded. Sounds pretty simple, no?[code]....
I'm using AS2, and trying to use AS2's packages for the first time, so I can organize my .as files properly. I'm running into some problems though I've got some classes that extend MovieClip, and I've put the class names in the Linkage>Class fields. When I publish, though, I get the error: The class or interface 'ClassName' could not be loaded. anyone know what I'm doing wrong? I tried importing the classes on the main timeline, and even including the directories of those classes on the classpaths list, but no dice
I was working with a sample code and when I do a 'cntrl + ENTER' I get a 'Type was not found or was not a compile-time constant: LoginEvent' error I also get the same error for the other events of 'RoomEvent' and 'XIFFErrorEvent'. My source files 'Test.FLA' and 'Test.AS' are located here: 'xiff_3_0_0src' whereas the various packages refered to in the source file are located here: 'xiff_3_0_0srcorgigniterealtimexiff'. My import statements are as follows:
