ActionScript 3.0 :: Event Handler - From Child To Main Button
Feb 26, 2010How do I get a button event handler to refer back to the main timeline from within it's movie clip inside another movie clip?

View 1 RepliesI have two classes in my project - a main class and a fancyText class. In main I create a new instance of fancyText and add it to the stage. Inside fancyText there is a timer that runs and when x time is up the fancyText fades out.
I'd like to know the best way to remove the child from main when the alpha of fancyText hits zero. Should i go down the route of adding a listener to fancyText in main, and dispatching a custom event from within the fancyText class?
I guess i could just check the child's alpha value in main and remove it when the alpha it's zero. But fancyText only gets added in a certain scenario - so i can't check it all the time - which would mean doing something like this:
Code:
...
addChild(fancyText)
checkFancyText = true (assuming a boolean declared earlier)
...
elsewhere in main -
[Code].....
Seems like there are a number of ways to do it - I don't suppose it's possible to remove a child from main from within fancyText class? or is that space cadet talk?
I import a external SWF into a UILoader, the SWF contains a netStream that I need to close from a Main.swf event handler, slideShow_btn. Basically from Main.swf when/if slideShow_btn event happens I need to check and close the nsStream in videoplayer.swf Here are my event handlers in Main.swf

I 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:
ActionScript Code:
import flash.net.navigateToURL;

I have the following codes,
for (i=0; i<answerArray.length; i++) {
var myOptionButton1:spark.components.RadioButton = new spark.components.RadioButton();
myOptionButton1.label = answerArray.getItemAt(i).Answer_Choice;

I am trying to figure out a way for an action script to change the background color of a particular button state.
I have a puzzle graphic. As the mouse moves over the pieces of the puzzle, the colors change. When the mouse clicks on the puzzle piece I want them to permanently change. However, I cannot figure out how to access the bgcolor property of a button state object, such as the up state.
I have what seems to be a simple task, yet I cannot seem to figure it out. I am busy creating a project in ActionScript 3, and while I am fairly fluent in ActionScript 2, I am being stumped a bit here.
I have a simple dynamic text field inside a button object. This text field has the name of txt_title. I have attached event handlers to change the alpha of the buttons when they are hovered over, however I also want to change the value of the text field within the button, when hovered over. My event listener looks like follows:

I created a screen(calculator) with bunch of buttons,i can handle button event with one handler.But i want to know that can we do a one handler for all buttons......likein java
we can perform the task of perticular button by like this
if(event.source=="button1")
{
}

How would I make an image I load using AS3's loader class into a button with an event handler on it? Below is what I have started. And below that is my error I get when I click the message.
AS:
//call function that starts loading my image
callButtons();
function callButtons():void {

the error I am getting when I click the spanish.png on the stage is: ArgumentError: Error #1063: Argument count mismatch on MyVideoPlayer_CS4_fla::MainTimeline/playSpanish(). Expected 0, got 1.I NEEDED TO ADDED evt:MouseEvent
I wanted to create a portfolio in flash, so I designed the layout in photoshop, with different webpages in different groups. So groups i created: home, about, porfolio, contact, affiliates, topbar, menu.I use Creative Suite 3 or CS3I then imported the groups into flash as movieclips, using the import to stage function. here is the image of the main scene in the flash. (SEE IMAGE 1st thumbnail)I created a new layer on top of all the layers and used labels at equal intervals to differentiate between pages.here's the image depicting the same.(SEE IMAGE 2nd thumbnail)Now in the home movie clip, i made all the text layers as movie clips to make button animations and assigned sounds and actions to them i.e. rollver, rollout andclick events. here's the swf.(PM ME FOR SWF)I want to know the code or method to load the frame labelled ''about'' in the main scene when i click on the movieclip button 'about' which is in the movieclip 'home'. Here's the code i tried for the first 'about' button, but it returns error "1120: Access of undefined property event."
code:
ActionScript Code:
var OverSound:roll_over = new roll_over();

In AS2 we can add additional event handler on same event as below code does.
on (rollOut, dragOut) {
// Statement 1
}
Now , I am workin in AS3 . So, how to add additional event handler on event in AS3
Let's say display Object's instance name is "myBtn"
Here I have include only Mouse Out only, Now I want to add additional event handler
myBtn.addEventListener(MouseEvent.MOUSE_OUT, myBtnEvent);
myBtnEvent(event:MouseEvent):void
{
// Statement 1
}
I have an event listener for a custom event type. This custom event overrides the clone method as required.In this event listener I want to dispatch an instance of a different type of event... a different custom event instance altogether. It also overrides the clone method as required.The problem is I'm getting a type coercion error: TypeError: Error #1034: Type Coercion failed: ...I do not know what is trying to do the casting. My code is:
/* elsewhere in a method */
addEventListener(GestureEvent.GESTURE_SCALE, handlePinched);
/* the event handler */

I 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)
Can event handler functions be called outside of the event listeners they are handling?
I am writing a flex application that has a MainMovie that loads flex programs (ChildMovie) depending on what the user selects in the MainMovie.
class MainMovie{
private var request:URLRequest = new URLRequest();
public function callPHPfile(param:String, loader:URLLoader,
[code]....
I can see that the callPHPfile function is being executed and received xml data from in httpFox, the problem is that the code in the handlerInChild function is not being executed.
When I click on Program (main menu), it expands the sub-menus.
1) Now I want that as soon as I click on the second Main Menu (Safety), it should collapse the other Main Menu that is already expanded or ("active").
2) Is there a way to add a "onRollOver" and "OnRollOut" handler on the Main Menus so that the user can mouseOver the cursor on the main menus to expand the sub-menus and to rollOut on the Main Menus to collapse the same.
How can I pass a variable defined on the main stage to a onClipEvent handler?[code]

I want to remove the appropriate child (e.currentTarget) and create a new child in its place with the next line, but it doesn't work. What do?
I have the next code:

I would like to use System.showSettings(0) up front and trapwhen the user chooses Deny instead of Allow in an onStatus eventhandler as I show in attached code.
View 1 RepliesI want to extend my function to a better design to where I can pass a canvas object into so I don't have to write N functions.. I'm not sure as how to do this properly I've come up with a naive design with a switch but even then if I add another canvas I still need to write new code for the new canvas.
function fadeCanvasOut(event:TimerEvent):void
{
canvas1.alpha -= 0.1;

We (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)?

I'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.
I'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.
I'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.
I have one event handler for several object's events. I would like to pass a value through to the function from the event listener:
ActionScript Code:
function chkEmpty(event:Event){
if(event.currentTarget.text==""){
[Code]....
So I am trying to essentially have one class dispatch an event into the flow when it is added to the stage, and have another class catch the event, but I'm having problems. I set up a little test to simplify/display the problem I'm having. There are 2 classes, and then just some init code on the timeline.
ActionScript Code:
//code for box 1
package {
[code].....
Is 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.
