ActionScript 3.0 :: Setting Event Handler For Button - Error #1009: Cannot Access A Property Or Method Of A Null Object Reference?
Nov 24, 2009I seem to be having a recurring problem attaching events to a button i have created within 2 other movieclips.I get the following error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
So it looks like it can't find the button, in order to attach the event listener. The question is why? I am attaching a similar event to a button on the main timeline and that works fine. So it looks like a scope issue, but I am referring to it properly.
code below:
Code:
import flash.net.navigateToURL;

ActionScript 3.0 :: When To Null And When To Delete?
Sep 9, 2009I recently bumped into an issue in the Flash IDE that you may be able to shed some light on for me.As I drag a movieclip around the stage, an enterFrame event listener is fired.For each enterFrame that fires, a point is placed onto the stage, stored into an array and the event.updateAfterEvent() method is called.
var p:MyPoint = new MyPoint(x,y);
parent.addChild(p);
myArray.push(p);

ActionScript 3.0 :: Calling A Mouse Event Handler Without The Event
Jul 13, 2009I am writing a program that needs to go to a random frame after clicking a button. However, the program also needs to start on a random frame. When I call the function at the start of the program it gives me an 1120: Access of undefined property event error. The function is originally written as followed:
function randomMatchedTrial(event:MouseEvent) {
... lots of code that probably doesnt matter, but let me know if it does...
}
the program starts by calling the function as followed:
randomMatchedTrial(event)

Javascript :: How Does Set Event Handler Scope
Aug 7, 2011We (AS3 coders) all know that one of the great things about the AS3 event model is that handlers are scoped to their containing objects. I'm writing an EventDispatcher for JavaScript, and trying to achieve the same effect.My question could be answered in a couple different ways:A: How does ActionScript 3 set scope within an event handler to the handler's container object, rather than to the event handler's caller (the IEventDispatcher on whom dispatchEvent() was invoked)?

ActionScript 2.0 :: Event Handler Not Working?
Jul 17, 2009I'm using a progress bar component in a movie clip and this progress bar works loading an external movie clip. However, once the external clip is loaded, it seems the "complete" event is not registering with the object listener. This is what I have:
ActionScript Code:
this.createEmptyMovieClip("FOB", _root.getNextHighestDepth());
var progressBarListener:Object = new Object();[code].......
The code a little more complicated than this in that there is an array that stores some information and a setInterval command that calls the loadContent function loading each external movie clip. I can past the entire code if necessary.Also the progress bar component is set up as thus: in the main movie (root) there is a movie clip called progressBar. Within progressBar the component resides with a variant name of PB.For some reason, when the external clip is finished loaded, the progressBarListener doesn't seem to be called.
ActionScript 3.0 :: Set Event Handler From Outside Flash?
Aug 8, 2009I'm trying to find a way that I can control how a flash movie handles the click event from the HTML page outside the movie.
I run a website where we have advertising space for Flash Ads provided by our customers which, when clicked, open their own website in a new browser window (i.e. target='_blank') - however this causes us a few issues:
1.) We want to track the success of their ads, so we give them a custom URL that their ad should link to instead of linking directly to their site. This URL logs the click before redirecting the browser to the customer's website.
2.) Often the flash files we get use GetUrl() which seams to trigger the popup blockers in IE 7 & 8.
These two points mean we have to provide them with the custom URL for them to include in their flash ad, and/or tell them how to set up the movie to handle the clicks in a way that doesn't trigger the IE popup blocker, and this doesn't make it as seamless as it should be to place an ad on our site.
So, what I'm trying to do is find a way that I can reference the Flash movie object with JavaScript (or similar), and set the click event to open up a specified URL - so if the customer's flash movie doesn't have the right URL set in it, or is triggering IE's popup blocker it doesn't matter because when we display it, we can modify the event handler to use the correct URL and to open up their website without tripping any popup blockers.
ActionScript 3.0 :: Return Value From Within Event Handler?
Nov 2, 2009I'm editing an xml gallery.you can see how it works now here (thumbnails are different than images, cause it's just for the sake of testing now)[code]...
oki. this all works via for each loop which creates thumbnails dynamically. the event handler for the click on the thumbnail is inside the - also dynamically created via this for each loop - button over each thumbnail. more or less like this[code]...
and now: i'd like to add "next" and "back" buttons,so that the user doesn't always have to click the closing cross and go back to the thumbnails, but that he can also -once he selected an image - simply loop through the gallery image by image.
oki. so first i tried to get the name of the button clicked previously and store it in a variable, a thus this would tell which image should be loaded via loader (say, name instance56 means Image00002 was loaded, so if now user clicks next, Image00003 should follow) . but i'm simplytoo simple to get the variable out of the event handler and for each loop scope. i also tried to do it inside the event handler,but then it gets terrbily messy, and i can never force loader to load the right image.

ActionScript 3.0 :: Get Event Handler Function?
Jan 10, 2010Is there a way to get the handler(s) function(s) of an event listener?
I'm trying to find a way to remove them without knowing what they are.
For example:
ActionScript Code:
if (mc.hasEventListener(MouseEvent.CLICK)){
// this object has a MouseEvent.CLICK listener
mc.removeEventListener(MouseEvent.CLICK, null );
}
Instead of null, I was hoping to find some function that retrieves the handler function.

ActionScript 2.0 :: AddListeners, Event Handler And All?
Jun 18, 2007And by the way, what's the main differences between addEventListeners and addListener?I have a FLVPlayback component from which i wanna play 4 different flv clips referenced in a xml file.The xml part works fine.So I have my 4 buttons (components) here. When i click the button 1, i want to either send the variable 1 to a function that is build to load the desired flv in the player. The variable would determine which of the flv to play.either that or when i click a button, i want to set directly the .contentPath of my flv player, load it and play it via a simple function that would be referenced to in the addEventListener call hope everything is clear enough.I'm having trouble just making the buttons send different variables to a particular function, according to which of my 4 buttons are pressed.button 1 sends 0button 2 sends 1button 3 sends 2button 4 sends 3that looks pretty simple but seems like i cant even do that by myself.

ActionScript 1/2 :: Calling The On(press) Event Handler
Aug 13, 2009Typically when you set an event handler function for buttons by code, like:

trace("Hello!");
}
[Code].....
is that event function accessible from code? how? I know there would be a property that you can access it by, maybe we can "decompile" an SWF to check out finally which property it stores the event code
mybutton.onPress(); // This does not work!
