Actionscript 3 :: Propagate Custom Event To Parent Swf From Element Inside Child Swf
Jul 19, 2011
I have two swf file, A.swf and B.swf, each with its Document Class: B.swf is loaded in a MovieClip of A.swf. When loaded, B.swf creates an instance of CSDragger (it is a library object with its class extending MovieClip) and sets an ID property of this instance to a certain value. When this dragger is dropped by the user upon a MovieClip it sends a custom event containing the value of ID too. The custom event regularly reaches B.swf but never reaches A.swf. Aside from refactoring the CSDragger class (eg moving its handleDrop method in the B.swf document class), is there any way for the event to reach A.swf? I know I can intercept it and dispatch another event, but I was looking for a different solution (if any).[code]
I have got a custom event set up (see below), but when I listen for the event in my main class, and it gets dispatched from the child class, it never gets captured.
I have a simple 2 class game Im working on. It has a document class (BubbleBuster.AS) and a Bubble class (Bubble.AS). In the doc class I made a container sprite called bubbleContainer. I add bubbles (instances of Bubble.AS) to the bubbleContainer. When the game is over I fire a custom event in the bubbleContainer from the doc class like so:Code:bubbleContainer.dispatchEvent(new Event("gameOver"));Now I want to listen for this event in the Bubble children so I can kill tweens and remove things. So in the Bubble.AS I have:Code:parent.addEventListener("gameOver", gameOver);this compiles fine. But as soon the 1st Bubble is added to bubbleContainer I get this error (and no bubble appears):TypeError: Error #1009: Cannot access a property or method of a null object reference.
at Bubble/init() at Bubble() at BubbleBuster/addBubble()
I'm building an all flash site, where one .swf acts as the parent, and other external child .swf's are loaded in using .xml. The "Child.swf's" are a mixture of timeline animations, and coded swf's, and the problem I'm having is that they immediately start playing as soon as they are loaded. I've not been able to find any straightforward "child.start() or child.stop()" solutions, so I assume it's more involved than that.
I thought it might be a good idea if I could dispatch events from the parent swf that will set them going. I'm using the sharedEvents method to communicate in the reverse direction (child to parent), but I don't believe it can be used from parent to child (Please correct me if I'm wrong!) I know I could go to each child and put "stop();" in the first frame, but how do I start it again? I would also prefer it if not all the child .swf's started immediately, but to wait until others have completed their routines. Again the way I see it is to dispatch an event from the parent .swf as soon as I'm ready to set them going.
I have two swfs for a project, I had both of them to dispatch events to each other. Parent loads child and is listening for the compete load event. Once that event is dispatched to the child - the child dispatches a start event back to the parent. I got this working by copying the ModelEvent(my custom event) in each of the flash builder actionscript projects in the exact file structure ( i think i was cheating it there, since )
It broke when I put the swf on separate domains, so I'm thinking I'm missing something to share the custom event class between two swfs.
I have created event listeners for a particular movieclip.Insidet this movieclip there is so many objects.When ever I click on the parent movieclip the event listener calls the function for the child object. I had tried removeEventLIstener()
import flash.display.MovieClip; import flash.events.Event; import flash.events.MouseEvent; var info:MovieClip=new MovieClip(); info.graphics.beginFill(0x000000,0.35); [Code] ..... I want to delete mc's parent
I want to listen for a custom event dispatched from the document class in a custom subclass. For example, let's say in the document class I have:
ActionScript Code:[code]....
So that the subclass will trace 'Event from document class received' when the 'customEvent' event from the document class is listened by the eventlistener. However, the output is only 'customEvent dispatched', meaning it wasn't heard in the subclass.
I have movieclip which contains child movieclip. when child movie clip finish to play i want to run a function in a parent movieclip. so I made a custom event dispatcher in the first frame of the child movieclip:
type_elt is not an element name; it might be <single>, <multiple> or something else, determined at runtime. How, given this, can I detect the presence of the opt_out_flag element?
I tried this (where xml refers to the question element):
if (xml.*.opt_out_flag) { do_something(); }
but even in cases without opt_out_flag the above expression returns true. Obviously I'm missing something, but what is it?
I am building a compartmentalized Flex application which uses <SWFLoader > to load additional Flex applications inside it. I am currently planning on using the LocalConnection class to have these two applications talk to each other, but I'm wondering if there's any kind of event driven way to have actions in the internal application propagate to the parent application, and/or any way for the parent application to trigger events in the internal application?
I'm trying to check if a clicked element is inside of an IVisualElement in Flex 4. So I want something like "if this element is in this element, then execute function". I'm aware of the 'parent' property but this doesn't seem to work when my element is not a direct child of the element but for example 3 levels deep.
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:
Recently I worked in a project using Flex. Its a Photo editing project. I have took a Canvas and take a image in that canvas using the code canvas.addChild(image) . Now i can move the image freely by using moving code. The image move inside the canvas and outside the canvas. I want to move the image/child only inside the canvas not outside. How can i do this?
I am trying to get a circle shape and a text-field sit inside a square sprite, using addChild() method. Both the children seem not to agree sitting in the lap of their parent; and are sitting at a distance, instead. If I create a square symbol on the stage and run the application, everything is fine.
I got a Parent Sprite, let's name it SpriteP, which holds inside it two other Sprites. Sprite1 and Sprite2.[code]Sprite2 is a rectangle. When I rotate it, of course, the height of its parent, SpriteP, GROWS. But I would expect that height to go back to what it should be when I'm removing Sprite2!And it does! If I remove Sprite2 while NOT being rotated, the height of the parent drops back to normal, 200.
i am slightly confused about the parent and child relationship. lets assume we have several different instances, what would be difference of adding them all as children of the stage and creating a parent-child hierarchy between them(other than the access path).
I got a Parent Sprite, let's name it SpriteP, which holds inside it two other Sprites. Sprite1 and Sprite2.
When Sprite2 is NOT rotated:
Code: trace(SpriteP.width + ' ' + SpriteP.height); //100 250. SpriteP.removeChild(Sprite2) trace(SpriteP.width + ' ' + SpriteP.height); //100 200. -> works, 200 is good. When Sprite2 is rotated at 90:
[Code].....
And it does! If I remove Sprite2 while NOT being rotated, the height of the parent drops back to normal, 200. But if I rotate Sprite2, the Parent won't update its bounds.
I'm trying to place an event on a child and not the parent but it doesn't seem to trigger the event. Example. Code: parent.child.buttonMode = true; parent.child.addEventListener(MouseEvent.ROLL_OVER, onMouseOver ); private function onMouseOver(evt : MouseEvent) : void{ trace("child = "+evt.target.name); } The above event is not getting fired.
I have an element which listens for the MOUSE_DOWN, MOUSE_OVER, and MOUSE_OUT; in that there is a child which listens for MOUSE_UP, MOUSE_OVER, and MOUSE_OUT. The issue is that although OVER and OUT seem to work together (And I like how that is) I need it that if the child is clicked, that the parenet doesn't recieve it. (Right now they both recieve them all, and I only want OVER and OUT to be recieved by both)
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.
In my AIR application, I try to dispatch a custom event from a class to main window.This class is use to call httpservice. My goal is to send a custom window when the httpservice result is send.[code]...
I have a dialogBox with 2 buttons - ok_btn and cancel_btn. The code is in a Class - testDialog.
There are 2 issues:When any of the 2 buttons clicked, they dismiss the dialogBox without sending any alert to the parent (main time-line).How to trap the clicked buttonId in the parent.I have just an idea of the solution as dispatching an event in the child and listen for that event in the parent. But, unfortunately, I don't know how to go about it.
I have a sprite A which has a child, sprite B.Sprite B has a variable, instance of class C which only extends EventDispatcherIn class C, I dispatch a custom Event. The eventlistener in sprite B reacts on the event.The same eventlistener in class A doesn't respond.If I dispatch the same custom event in the eventhandler in class / sprite B, this event is seen in class / sprite A.Is there a difference in events going through the displaylist and those who are from an EventDispatcher?
I have a movieclip(parentMC) which consists of several other movieclips(childMCs). Each childMC can trigger an event, and each event performs a different function. I want to check from my parentMC whenever there is an event triggered by any of its child.
