ActionScript 3.0 :: Custom Event That Bubbles Up From Items Object
Apr 22, 2007
I'm trying to make a custom event that bubbles up from the Items object in this code to the Main object, and start the changeInfoHandler there. For some reason, it works when I put the dispatchEvent in the Items object inside a handler for a mouse click, but when I try to bypass that and call the function directly, it seems to only work in the scope of the Items object.
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.
how to get my CollectionEvent to work, and I seem to be able to see the problem, but I am not sure how to get it to work properly.
In my actionscript, it seems to only tell that event.items.length is 1, while I am calling my array collection from the HTTPService, and I have tested the length of my Array Collection, which seems to be accurate. What I tried to do is to use that number in the CollectionEvent function, but that does not work at all.
Attach Code
private function onChange(event:CollectionEvent):void{ for (var i:int=0; i< event.items.length; i++) { Alert.show(event.items.length.toString()); //This always gives me 1 when I have 12 items
I have small swf as3 flash applications that are loaded by a main flex application. The main Flex Application contains an SWFLoader and i added an event listener on SWFLoader.content to fetch custom events that I prepared.
now whenever I like in the application I use the function dispatchEvent to create the event and I make sure that the bubbles parameter of the event is true. so in this case the event bubbles up in the stage until it reaches my event listener and I can handle the event properly. the problem resides when I have a static class and I want to dispatch the event from there. because it's a static class and not a display object that appears on my stage it has no where to bubble to and because of that I cannot fetch the custom even in my main flex application.
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'm in a Flex Mobile application project. I need to dispatch an event to the lexGlobals.topLevelApplication and it has to contain a custom message. I'm trying to make an object and dispatch it like this:
//create the event Object var receivedObjMsg:Object = new Object(); receivedObjMsg.name = "receivedMessage"; receivedObjMsg.message = messagevarhere;
I have a utility class that I use to load images that never gets added to the stage and is extending EventDispatcher, it simply loads the data and spits it back out on request.
I want to add a custom event to track loading progress from outside the class. The events are firing but not (i think) bubbling because they aren't in the display list.
Is there a good way around this? I was thinking: Can I have a non display list object tell a display object to send the custom event for it?
I have searched on the Internet and didn't find any clue on how to do so, any idea ? I don't want flex only flash (my objects are not visual components).
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 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?
Does anyone have any good references to point me towards in regards to creating space between custom tagged items in XML other than the <p> tag? I created some other tagging in CSS such as <paraPop></paraPop> and I tried creating custom tags for spacing alone, but it doesn't work in CS3 like it has in the past with AS2. Example of spaced tagging used in XML that worked previously: [code]
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 am trying to create a combobox where the items listed in the combobox are font names and each item will display using the font of the item label. For instance, one item label in the list is "New Times Roman" and I want that particular row in the combobox to have the text AND font of "New Times Roman". For some reason, inside of my custom CellRenderer class, I cannot seem to find a way to get the item label that corresponds to the CellRenderer and the CellRenderer.data item always appears to be null!
This is the code I am currently using:
//From the main class, I am creating an instance of the CustomizableComboBox and adding in the font names I am interested in. var comboFont:CustomizableComboBox=new
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?
What I want to do is be able to click a button that adds an Item to the stage and then you are able to drag the item around on the stage. I know how to do these things separately as in if the item is already on the stage I know how to add the code to drag it and I know how to create a button that brings a library item on the stage. How would I combine the two?
I'm trying to make a flash version of those refrigerator magnet poetry kits. As such I have about 150-180 little MCs each with a different word. They are all named sequentially, so theoretically I could just make some array counter or something to stick the handlers on right?
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.
