ActionScript 3.0 :: Specify A Custom Event In An Instance?
Sep 30, 2010
I have a button which is an instance of a "button1" class. The button is instantiated by an instance of the"introScreen" class which is instantiated by the "screenHandler"class. I'm not sure how to attack getting an instance(the "button1" instance ) to dispatch an event heard by its grand parent(the "screenHandler"instance). My main confusion is getting an instance to transmit a specific event like the name of the screen to switch to. Can I specify a custom event in an instance?
This is NOT duplicate of my earlier post (its is slightly different)But this is similar issue with similar error but its not the same error The error I am getting now is below while dispatching the custom event from my custom component
TypeError: Error #1034: Type Coercion failed: cannot convert events::MapEvent@a74ab51 to flash.events.MouseEvent. dispatchEvent(new MapEvent(MapEvent.CLICKED_ON_MAP));
Note: The error in my earlier post is giving below error message
Type Coercion failed: cannot convert flash.events::Event@81ecb79 to com.events.ShopEvent
The difference here are two things, the earlier error is while converting flash event to custom event and now this one is while converting custom event to flash event and secondly, I have no clue why it is trying to convert to the mouseevent where I am just dispatching my custom event with proper listeners.
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 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.
I have the following situation:I have an event handler, that displays small messages in my application's statusbar.These messages get passes through by dispatching events from custom components.A simple message could be like "HTTP Error" or so.Now, the main event listener, in the main application file, listens to the event dispatched by any custom component,but seems to refuse listening to events dispatched by custom AS classes.Here is my code for the custom event:
i am a bit embarassed to ask this, but i do this so much i have to ask. Occasionally, i need to pass/handle custom events on the fly. Rather than creating a whole custom event class, i will just do something like
Code: myObject.dispatchEvent(new Event('thisCustomEvent')); //and then handle it later
I have a custom Flex 4.5 component (to be used in a List) -
Game.mxml (represents a clickable playing table in a card game): <?xml version="1.0" encoding="utf-8"?> <s:ItemRenderer [code].......
But I never see the "game clicked: " trace. Does anybody please know why? I'm probably missing something minor, because I can see the "Clicked: 8946" trace.
This is similar to the question asked here. I am dispatching custom event "ShopEvent" but i am getting error "Type Coercion failed: cannot convert flash.events::Event@81ecb79 to com.events.ShopEvent"Note: Error is thrown from the parent custom component (3rd code snippet), I have added more details thereThis is my custom event. See the first constant, I copy pasted the event name in custom components.
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 am trying to understand event propagation in Flex framework and have a following doubt on it:
Scenario: I have a built-in component DropDownList on change of which I want to create a custom event refreshPreview and want to propagate it to a custom component PictureComponent.
In the custom component's mxml, I have added the Metadata directive as follows to register a refreshPreview event with the compiler
Layout Details: In my main mxml application I have laid out DropDownList and the custom component such that both are siblings (i.e. have a common indirect parent) e.g.
I am seeing that the refreshPreview event is not getting propagated to the custom component.
I doubt this is because the built-in component is a sibling of the target (where the event got generated) and not a parent. how to make refreshPreview event propagate to custom component?
printableInvoice.addEventListener(batchGenerated, printableInvoice_batchGeneratedHandler);Results in this error: 1120: Access of undefined property batchGenerated. I have tried it as FlexEvent.batchGenerated and FlashEvent.batchGenerated.
The MetaData and function that dispatches the even in the component printableInvoice is all right. It I instantiate printableInvoice as an mxml component instead of via action-script it well let put a tag into the mxml line: batchGenerated="someFunction()
I'm using a Static EventDispatcher for all event handling in my application, and one of the issues with it is that the Static EventDispatcher becomes the target and currentTarget of the custom Event. Usually, I just pass the event to the custom event which it will carry as its own property. I usually call it "scope". So, instead of using "evt.target" or "evt.currentTarget" in the event handler, I use "evt.scope.target" or "evt.scope.currentTarget" instead. This works fine.
The issue is that I want to simplify this with custom events by overriding the target and currentTarget methods so that they return scope.target/scope.currentTarget. At run time, I get an error saying that I cannot convert Event to whatever I named the custom event. So, I tried not extending Event, and that produced an error stating that the class function is expecting exactly 0 parameters. I just want to make it so that people using Static EventDispatcher handling events as they normally would.
So, the question is there a way to override target and currentTarget while extending the Event class, or is there a way to create a custom event without extending Event?
deleting class instances. say i have a bullet class. say the bullet class checks when the bullet hits an enemy. how to delete the bullet when it hits the enemy.

Through searching the various forums I have found that Loaders are not dynamic and hence you can not apply custom properties to each instance of them. I miss the old way (as2 way of attachingMovieClip) that you load dynamic content, at least you can apply custom properties, and you can always reference them for each object.What I'm trying to do is load a group of Images via XML. Each one of those images have a set of information that is associated with them (name, description, etc). I have the images loading in and positioning just fine, however when trying to have a tooltip show the name on Mouse Over, I'm not able to achieve this.
In short. I want to be able to store information for each item so that I can access it. Is there a way to do this in AS3 with a Loader or is there another route I can go? If I do this with Arrays, how do I store the Index of the specific item so I can use that in reference to the position in each array?** Should I use getChildIndex() in the function for the Event Listener to reference the data stored in the arrays for each item? If so, how do I do so? ***
PHP Code: num = 0;var titleArray:new Array();function createImage(){ var thumb:Loader = new Loader; thumb.load(new URLRequest(url);
I have a repeater component with custom event. My repeater components fires custom event holding data. My need is to dispatch event so other repeater components can access data from dispatching component.
I have created some (TextInput, ComboBox, CheckBox) Component instances (created as a public objects) in a Document class and added them to the stage.
Now I have created a custom class for a movieclip in library and instantiated it in the document class (also a public instance).
I need to access the component instances in the custom class. How to do this ?
Also, Is it a good practice to use ENTER_FRAME event frequently ? because if I can't access the above components instances in the custom class then I will be left with no choice but to use ENTER_FRAME event in the document class every time I need to change some value in the components...
I am trying to replace a MovieClip with an instance of my custom class CustomMovieClip. What I want to do is make all references to MovieClip refer to CustomMovieClip, something like the following:
Code: var _mc:MovieClip = new MovieClip(); addChild(_mc); _cmc:CustomMovieClip = new CustomMovieClip(); replaceMc(_mc, _cmc); trace(_mc); // I want it to output '[class CustomMovieClip]'
I want this to work so any variables that hold the MovieClip should refer the the CustomMovieClip after the replacement. Is this possible?
[AS] class test extends MovieClip { private var butnPath; function test() { butnPath = this.cool_button } }
I assign this custom class to a MC containing a button with a instance name 'cool_button'.This code gives a me a compile error of 'variable cool_button not defined', what i am trying to do is reference something that is in the MC itself. The only solution i have found is to name the var the same as the instance name you are trying to reference.
I would like to make a new instance of a MovieClip within my library from code written in my keyframe. I relise that you can do this by making a class and using the codeCode:var instancename:movieclipname = new movieclipname(); and with the MovieClips class I would need to extend MovieClip and nothing else. I am unsure if you put in the name of the MovieClip or the name of the MovieClip class in the code above so feel free to correct me. But instead of doing this can I just add a MovieClip to my stage with doing this
Something I've been struggling with and can't seem to figure out. What I want for a system is to create several components, BUT each with their own timeline. For instance for a quiz, I want a number of answerbuttons. But each one should have their own appearance, preferably on a timeline. However these should be components, seeing their 'answerbutton'-logic should be the same over all buttons (apart from their answerbutton-index, set in the Component Parameters).
I am using Flex 4 and for whatever reason I cannot get the following code to work which happens inside of a ListEvent handler for a dataGrid: _tempRule = DataGrid(event.currentTarget).selectedItem as Rule;
Rule is a custom class, and the above code always returns null. The dataprovider for the datagrid is an ArrayCollection. If I try to wrap the above code to make it like the following: DataGrid(event.currentTarget).selectedItem as Rule
I get this error: TypeError: Error #1034: Type Coercion failed: cannot convert Object@e15a971 to com.mycompany.arcc.business.Rule
Now I know I have done this before with native Flex classes like Button, etc, but it my case it will not work. Here is the Rule class: package com.mycompaany.arcc.business { import flash.utils.describeType; import mx.collections.ArrayCollection; [Code] .....
I am using Stage Video and would like to implement video controls to this, like the ones utilised in FLVPlayback component. I am coming to the conclusion I am going to need to create a custom control bar entirely from scratch.
I'm having a problem with customized Actionscript objects not recognizing thier own constructor. This is the pertinant part of my script:
ActionScript Code: //File: Line.as class Line extends Object{ public function Line(args){
[Code].....
Clearly, the variable "testLine", is one of my custom "Line" objects. Clearly, it has been made with the "Line" constructor. So why won't flash acknowledge this?
