ActionScript 3.0 :: Event Added To_stage And Event.removed_from_stage.?
Jan 10, 2011
I have created a flash file with animations, buttons and videos which will be uploaded to Zmags - (Digital publishing platform for flat pdfs) Everything is correctly set up on my flash file, and the .swf files work fine independently. Once uploaded to Zmags, when turning to a new page within the interactive pdf, the animations plays a small clip before the page is fully loaded. Once the page is fully loaded, the animations and buttons etc work as they should. I do not want this short clip of animation to run when the page loads.
Now I have been told that the solution will lie with: Event.ADDED_TO_STAGE and Event.REMOVED_FROM_STAGE.
I am informed that these event listeners will ensure the page is fully loaded before the animation plays.how to add these into my ActionScript,.I have the actions on the first frame of the timeline and have used frames to create a contents page, so when your mouse hovers over the pages numbers (buttons), different animations happen (which are contained in the frames) I have no clue what to do next to add Event.ADDED_TO_STAGE and Event.REMOVED_FROM_STAGE.
ActionScript Code:
one_btn.addEventListener(MouseEvent.MOUSE_OVER, onebutton);
function onebutton(event:MouseEvent):void {[code]...............
What is the difference between Event.REMOVED and Event.REMOVED_FROM_STAGE? I thought when you have: removeChild(mySpriteInstance); that this removes the item from the stage...is there a different kind of removed?? For example, if I am trying to "clean up" after an item is removed for the garbage collector...should I be listening for:
How can I do this in AS2?I have been trying to use the delegate class to set up an onEnterFrame event that I can then remove. I have this working with events for button clicks etc but not onEnterFrame. Well, i can get it working, but how do I set it up so I can remove a specific onEnterFrame, as I need to use multiple onEnterFrame throughout the script?
I just started a course that does a little flash. To teach us they have us build a brick breaker game. I have come to a part were I have to remove all the Listener that were created for the game. Each level is a movie clip and when the level is over the level instance is removed from the child. From what I understand when the level is removed the Event.REMOVED_FROM_STAGE becomes true and the function attached should be called however it is not. Here is the code of the function that sets the listener and the function to be called:
[URL] I needed to do clean up before the MC is gone ... so after some digging I found this event:
Event.REMOVED_FROM_STAGE
So I am trying to ask for some conformation here: Is this the ONLY situation that my MC will be deleted automatically by Flash? If so then I can just listen to this even and call my cleanup function when it happens...
Can event listeners only be added to the class which dispatched the event? I ask because I want to have the logic for the listener on the main class, and the action is dispatched on click from a thumb which is instantiated in a scroller class. Kinda like this:
ActionScript Code: pseudo code: class main { main() {
[code]....
This doesn't work. Why can't the main class listen for an event on the thumb class?
I'm trying to set up a simple button navigation system with a for loop that pulls a mc out of the library "i" number of times, adds it to the stage, then adds an event listener to it with a unique function name -- something like "onClick1, onClick2, etc", but with onClick[i] somehow in the loop instead.
var btnArray:Array = new Array(); for (var i:uint = 0; i<6; i++){ var myBtn:btn = new btn(); btnArray.push(myBtn); addChild(btnArray[i]); btnArray[i].x = i*50+50;
I have this slight problem with the event ADDED_TO_STAGE. The listener is launched twice so I figured the event is dispatched twice.
Here is my .fla code : var section:SectionStructure = new SectionStructure("xml/list.xml") addChild(section)
The Section Structure code : [...] mainHolder = new MovieClip; mainHolder.addEventListener(Event.ADDED_TO_STAGE, displayObjects); addChild(mainHolder); } private function displayObjects(pEvent:Event):void { mainHolder.addChild(sectionMenu); } [Code] .....
The output panel displays "test A" once and "test B" twice. I fixed the problem by adding this little line on the opening of the function createButtons : menuHolder.removeEventListener(Event.ADDED_TO_STAGE, createButtons); I read here and there that the event ADDED_TO_STAGE is dispatched when children are added but my problem remains even when I comment everything below this line : trace("test B");
- I have a constructor method which is trigerred automatically once the program starts - The method's argument determines whether or not an enter frame event is to be added(move:Boolean = true) - If true, add the event listener - there are getters and setters created to access the variables from another class
The problem is that the event listener is run only once - at the initial phase, so it checks the move's value just once (true - add, false - don't add), so it can be turned on and off only in this class. I want to allow a user to change its value from an external class, which is impossible even with getters and setters, because it adds the listener before the user even gets a chance to change it. I want the listener to be added only if the user wants it to. I know it looks complicated,
I would like to pre-process *any* item added to the display list of my main movie clip, so I attached the Event.ADDED event to the stage.
Seems to be working fine for timeline objects and objects loaded from the library (such as addChild(newClass())).
But I don't know how to manage stuff loaded from an external SWF. I'm getting Event.ADDED when I addChild() the loaded swf, but not for its children...
How can I know who are they children? (avoiding ENTER_FRAME if possible).
I have created a button class which has graphical elements. In future I might want to add this as a child to other things so what I would like to know is, firstly, can I get the details of the parent object from the child and, probably more importantly, is there an event that tells me when my button has been added as a child so that I can resize it?
I have editable grids which are 2-way binded to my model. What I want is to validate my data when user edits any cell before it get updated in model. I have applied my validation at ItemEditEnd handler, but, I want to apply validation in between itemEditBegin and itemEditEnd events.
I want to know when the data has been added to a chart so I can use localToData() to draw on the chart. If I do this immediately after setting the dataProvider the chart has not yet updated, so the the call to localToData will not return the correct values. Is there an event I can subscribe to so I know the chart has drawn the data in the dataProvider?
My problem is basically as follows. There is an instance of a class extending EventDispatcher. Everything goes well when I add event listener to the object like this:
[Code]...
Now someFunction is not called even though the line containing dispatchEvent('eventName') is being executed just like before (and there is an external reference to myObject as well). The application I'm developing is quite complex so, unfortunately, I can't post the exact code.
I hava a custom component and it contains a child icon. If I add a mouse-click event listener to both component(click-listener1) and icon(click-listener2), the event dispatched sequence is click-listener2, then click-listener1. I can understand it. But if I add a custom event to component (listener1), and mouse-click event to icon(listener2), when icon is clicked, the component will dispatch the custom event. In my test, the event dispatched sequence is listener1, then listener2. It doesn't match with event-bubbles rule.
In my opinion The custom event is dispatched in listener2, which triggers listener1. Why event flow sequence is not listener2, listener1?
In component.
icon.addEventListener(MouseEvent.CLICK, iconClickHandler); private function iconClickHandler(event:MouseEvent):void {
I am trying to make an animation with three seperate buttons that when clicked on make one set of text disappear and new text appear in its place. My code so far looks like this:
What is the correct event listener to detect a child added to the stage? I tried:
[Code]...
which doesn't work. I also tried ADDED_TO_STAGE but that doesn't fire it either. Do you know the correct way to detect when the child is added? Perhaps I should be attaching the listener to the parent instead?
I was trying to load an external SWF (that contains the below code in its document class) with the Loader class but i keep on receiving Error #1009: Cannot access a property or method of a null object reference. So i tried to use the event listener Event.ADDED in MyDocumentClass constructor of the external SWF to let the document class be part of the display list before i invoke createRandomGraph. But when i place createRandomGraph( ) inside onStageReady, The compilation process hangs. When i leave the createRandomGraph( ) inside the constructor, it works perfectly as stand alone but will produce Error 1009 if loaded within the loader SWF
public function MyDocumentClass( ) { this.addEventListener(Event.ADDED, onStageReady);
I added a click event to the stage but this event also fires when i'm clicking a movieclip on the stage.How can i make this event fire only if i click directly on the stage?
Could someone explain when does local SharedObject triggers event handlers added via addEventListener?I have tried and it doesn't trigger, after flushing.For example i have two object.swf both in separate browser tabs.I'm adding data inside object.swf on one tab and want event to be triggered in object.swf from another tab.Is it possible with native functionality and without remote type of SharedObject?Ofc i could write infinite loop and check local storage for changes, but it's the last solution i would like to implement.I was reading docs and played with example over there, but it doesn't trigger event, even if it is added before flushing.[code]
I'm having trouble getting the Video class to work.. Everything works fine until I try to add an on enter frame event listener to the movie. I basically want to overlay an effect that gets updated every frame but adding the event listener causes the movie to freeze before it loads or on the first frame or just shortly after starting play back.. Check out the source code at [URL]
It freezes even if the enter frame method body is commented out so I don't think it's because of extra overhead..
I m using a dynamic text field in my app. I have added one Event.Change Listener on it. When I type into it with the keyboard, the event triggers. But when i set some text in it when user performs some action, like textfieldName.text = "test" then the event does not triggers. In this type of situation where we are not using keyboard, which listener should be added to text field to trigger the change event?
I am trying to learn JavaScript and I am wondering whether JavaScript has a event listener just like ActionScript's ENTER_FRAME. Basically, I want this event listener to listen "all the time" not just wait for any particular instance (mouse click, keyboard event) of event.
With the Google Maps Flash API, I want to add an event listener which fires when the Marker is added to the Map using map.addOverlay(); Event.ADDED_TO_STAGE is not fired, though it seems logical. What are the alternatives?
I got this very strange behavior from FlashPlayer debugger 10.1 r82. When I call loader.load method, no ADDED event is dispatched to the loader object. But if I open the file and call loader.loadBytes instead, an ADDED event is dispatched to the loader object. I suspect the ADDED event is dispatched because the content is being set as the child of Loader object, but why in the other case it is not dispatched?
Basically I am dynamically calling product buttons, which on rollover invoke a child of a dropdown, which in turn invokes children which are squares filled with colour.What I need is for these squares to be clickable which will then colour something else using the colourMatrixFilter (I'll probably start another post for this problem at a later date).For some reason though adding the Square as a child to it's rightful parent - the dropdown makes the listeners completely useless. Add to the stage and the listeners work. I can't work out why either and have done loads of searching.[code] also if someone could show me in the right direction of pulling the XMLdata for the squares (which will be a name attribute).
I am having trouble using a custom event in flex. I need to dispatch an event from inside two nested components and receive it in the main application file. The basic set up is a main application file importing a custom "gallery" component.
