ActionScript 3.0 :: Create Event Class That Can Handle The Target Property?
Jan 30, 2009
I'm not sure if it's possible, but can you override a variable of a parent class like you can override a function? I'm trying to create my own event class that can handle the target property. I have a custom imageLoader class, but when it dispatches it's loading complete event:
ActionScript Code: dispatch(new Event("load_complete")); and a listener picks it up, e.target = null where I would like e.target to equal the imageLoader instance that has finished loading.
Does anyone have an answer or a better way to accomplish what I am aiming for?
in Adobe tutorials, they suggest to create a class to handle the events (see below the copy/pasted code, and link to page).I was wondering if I have to handle all events with the function handleAllEvents, using if statements to check if the target is the one I want, and the event is the one I want.i.e. if (event.type=="click") && (event.currentTarget == "myId")Should I have a list of ifs (for each target and each event type ?)[code]
Is it possible to grab an event, hold it in a class property, do some action, then, when that action is complete, dispatch an event and then retrieve the original event.target in the listener?I am trying to avoid using a custom event for now, as it is giving me massive amounts of heartburn when dispatching it from a loaded SWF.Here is some code (that doesn't work)what I am attempting to do:
I am able to stash the event in a class variable, and then access it later, but the cherry on the icing would be to get it from the event fired withing tweenHandler() in my example above.
Edit: Well,it doesn't look possible.I am currently storing the retrieved event in a property _event and then getting it at a later time when I need it.This seems to work, but isn't wonderful.
I have mutliple instances on the stage of a custom ThumbNail class. As you click on a particular instance an associated enlarged external image will load. As this is happening I want to make sure that the ThumbNail class animations are inactive for all instances.
I was thinking of using a Boolean variable that would get set right before the image is loading. Using event.currentTarget should help with the instance that was clicked but how do I gain access to the instances that were not clicked?
I just recently been using a lot of prototype javascript stuff, and was wondering there was anything like the "bind" method, for use in AS3. It's proved quite useful to be able to look both at the event.target as well as the class object the handler function might be associated with.
I have a question about accessing properties of a custom class from within another class. I can do it, but I'm not sure if I am doing it the right way or if there is a simpler alternative. I have a class called legion it contains a couple of properties, a sprite called legio and an integer called loc I import the legion class into another class called Main.
Within Main I have a loop to create many versions of legion, passing parameters so that they all have unique loc values. These are put into an array called legarray:
I want to create an event in my class. I want to create an event when a number variable =4.private var loadNum :int;In this class with the event I have extended this as a Sprite. I want to test when this variable = 4 and execute a function when this is the case.How do I code this?
i try to migrate from as2 to as3 and i have one problem When i attachMovie from library (addChild in as3) and i add custom property its work fine.Here is ex.
Code: var i:int; for (i=0; i<5; i++)[code]....
when i attach to that symbol custom class in the library.i got the error: #1056:Cannot create property...
My problem is: I'm trying to create an external class which function is load an external sound file and play or stop depends on stage.activate and stage.deactivate events. The actionscript 3 in the timeline is functioning properly, but when I try to create as external class, it has so many errors. So many that I can't troubleshoot them. Btw, it's my first class creation. Is there anybody who kindly enough to give me some guidance to create a proper class with stage event listener?
I am new to AS3, as well as Flash in general, so forgive me if this seems highly elementary. All I am trying to do is create a custom class that extends the MovieClip class and contains a custom property of "marker". I want to be able to use and change the value of this custom property on the timeline for an instance of this class and have it behave just like any other (Ex: this.x ==> this.marker).
How do I create a custom event class similar to ActionScript? What I mean by that is a class that I can use to fire off my own events, send the necessary data.
I don't wanna use third-party libraries like YUI or jQuery to do it. My goal is to be able to send a event that looks like this.[code]...
how can i access event.target outside event listener method.say for example
my_mc.addEventListener(MouseEvent.CLICK, onC); function onC(e:MouseEvent):void { var m:MovieClip = e.target as MovieClip; } trace(m.totalframes);/// not working
now what if i want to get totalframe property of m instance, in short for every movieClip clicked.
I have these buttons in a movie clip and I would like to have only one event listener for the parent, using event.target to point to the children. I have also tried event.currentTarget, and it didn't work.here is the code that works:
i'm new to AS3. Couldn't understand what some of the explanations out there are getting at, so i decided to post it here. In the code example below, what does event.target & event.currentTarget point to?
I'm running a recursive function which in the worst case senario is of factorial order. (i.e: runs itself n! times)As soon as n exceeds 7 in these worst case senario's the function times out (Error #1502). I want to handle this error event so that the user can be presented with an error that the problem is too complex.I don't want to extend the timeout period as 15 seconds is reasonable.
According to Cairngorm architecture, we always have a fault handler in every command class for each service.How we can create a single Class for handling Fault handler event for all the services.
I've a flash site 100x100% in browser window. When I open new tab in browser window Event.RESIZE doesn'tdispatched.how to handle this event except EnterFrame or Timer listeners?
I am working on integrating the social network "vkontakte" into my desktop application using Adobe AIR. The flow of authorization in the app is as follows:
Open the web browser with a url, and when the user inputs login and password, redirect to somePage.html. From that URL, I need to get an access_token to sign all future API requests.
So the question really is: How can I listen to an event, which will indicate that the user has logged in successfully, or failed to get that access_token?
I have a Flex 4 List component which I have tied a click event to. In my event, my assignment of the source file paths works just fine --> my larger image displays just fine when a thumbnail click happens. My problem comes when trying to attach elements of the dataProvider to text inputs on another panel. Actionscript is throwing an error. Can someone point me in the right direction??
Does addEventListener(ErrorEvent.ERROR, handler) handle all type of error event, for example, IOErrorEvent.IO_ERROR, SecurityErrorEvent.SECURITY_ERROR, and other all error events? I'm looking for addEventListener() version of try catch(e:Error)(e:Error can catch all type of errors).
I am trying to perform two way binding e.g I have a button (out of many controls), on its selection, I am showing the values of its diff properties(like height, width etc) in some textinput. This one way process works fine.But the reverse process doesn't work. i.e When I select some button, and try to change its dimension by entering some value in height, width textinputs, the dimension are not changed.
private void Form1_Load(object sender, System.EventArgs e) { //Create some data and bind it to the grid
