Flex :: 4 - Multiple Instances Of A Custom Component Listening The Same Event Of A Parent

Jan 28, 2011

In short: I need an event listener in a custom component so all its instances (without editing them) react at the same time, fired by a dispatched event in its parent container. In detail: I have a custom component with Tab navigator. (The tabs are intended to show different preferences for different Languages.) I have a button bar with buttons for all the languages. There are a lot of instances of the custom component.

I want to click in a button of the languages bar and get ALL the instances switched to the same tab (the custom component contains the logic to change the tab). I can do it by adding the event listener for EACH INSTANCE of the custom component, so it calls an internal function that changes the tab. But it seems to be very coupled, isn't it? I wonder if it can be done in the master CLASS of the component, so it listen for events in its parent container, whichever it is. In my mind this code shoud work, but it doesn't (obviously ill'use a custom event to pass the new language value): this.parent.addEventListener("lang_change", this.change_tab); This way I can just drop an instance of the component, and see it working for itself.

Actionscript 3 :: Flex 4.5 Not Listening To Custom Event Dispatched In Custom Class?

Nov 4, 2011

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:

package main.events
{
import flash.events.Event;[code]..

So to sum it all up:

- The event listener listens to the custom event dispatched by any custom component.

- The event listener does not listen to the custom event duspatched by an AS class.

Those who wonder, the event really gets dispatched, that's why I added a trace call.

Flex :: Custom Event Dispatch And Listening With Viewstack?

May 27, 2011

I got a question about event dispatching and dispatching in flex.

My goal is to pass an email address captured in one component (Comp1) and be passed to another (Comp2). These two components are navigator content of a viewstack. The custom event dispatched the email correctly from Comp1 but somehow could not reach Comp2. The application (Main) looks like :

<fx:Script>
<![CDATA[
import events.LoginEventComplete;

Flex :: Listening An Event In Main.mxml While In A Component?

Mar 9, 2011

I have an event, which I have dispatched in my main.mxml:

var evt:UserEvent = new UserEvent(UserEvent.USERINFORMATION);
evt.userVO = storeObject;
this.dispatchEvent(evt);

I can listen for it while in my navigation.mxml file, by using

this.parentApplication.addEventListener(UserEvent.USERINFORMATION, onInfo);

But in other component, I can not listen for it, even trying the same as I did in navigation.mxml.

tracing it back gives me an undefined.

the second component is in a viewstack in navigation.

Actionscript 3 :: Flex 4 Disptaching Custom Event From Custom Component (why Flex Converting Custom Event To Mouseevent)?

Mar 2, 2012

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.

This is my custome event

package events
{
import flash.events.Event;
import ui.map.MapElement;

Flex :: Make A Custom Component Or Extend The List Component For A 2D Top Down View MAP ?

Nov 11, 2010

I'm building a top view 2D map, that it's objects are stored on the server.The kind of objects are 10 and might be a photo, label, button, lists, mix of them or labels with tooltips.The component must request the "areas" that are missing on screen.An area is 1000x1000 px and is cached in flex.To move in the map, will be like in google maps (drag-and-drop).I should be able to have another list and move objects from one to another using drag-an-drop on objects. Ex.: I grab an objects from a list and I move it on this map, I release the mouse button and the item is placed there.Now the problem is: I build a custom component for this trying to emulate the item renderer for performance and recyclage, implement drag-and-drop on objects and request the areas that are missing?

or

I extend the List component from spark and I add some features as multiple kind of itemrenderers and use recycle on them. Of course it must be able to request the missing areas on the screen and cache it's data.Maybe create a custom layout is needed too.What I need is something that must be really fluid, so the lighter this component is, the better.

UPDATE: *There will be not any object over another.

*I will not use hitTest on bitmaps because all bitmaps are wrapped in another component,as they,for now are itemrenderers.

Anyway I already begin to do this using a class that extends the SkinnableDataContainer and a custom layout. As the layout is not like a grid, is sparse, random items at diferent points(x, y).How to get the localX and localY, relative to item renderer and not to the Spark List, from a DragEvent in Flex 4?

Flex :: Dispatching Custom Event From A Custom Component?

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.

Flex :: Define Custom 'contentGroups' In A Custom Flex 4 Component?

May 12, 2010

The spark panel component for example can be written like this

<Panel title="Skinny">
<child components ... />
<controlBarGroup>
<child control bar components ... />
</controlBarGroup>

[Code]...

The motivation here is that I can now create a couple different skin files to change the look and layout of those subgroups. Reading source of the spark panel, there are some calls within the mx_internal namespace such as getMXMLContent() which is a method of the spark group component, but which I have no access to.

Does the description above make sense? How can I create custom 'contentGroups' in my custom Flex4 component that can use nested mxml child components? Should I approach this a different way?

IDE :: Flex Application As Custom UI Component

Dec 22, 2009

I'm making a UI for a component in Flash. I wanted to use Flex and have had no luck getting the onUpdate exernalInterface call to fire properly. I'm referencing the functionality described here: [URL]. First off, I can't embed the SWF in the FLA. It just won't start the Flex SWF. Even using the external swf, it seems that the onUpdate function is either called too early or not at all. Here's what I've tried:

Tying the externalInterfce declaration to the initialize, preinitialize, applicationComplete, and creationComplete events. Sub-classing my application and putting the externalInterface in the constructor. Neither of these options work. When I create a basic AS3 project in Eclipse and put the externalInferface in the constructor, it works as expected.

ActionScript 3.0 :: How To Use Flex Custom Component In Class

May 27, 2009

Our software team has been developing flash applications using AS3 (via the FlashDevelop IDE and the free Flex SDK). Recently, some members of the team started exploring FlexBuilder and Flex (wow... why did we wait so long?). The problem is that some folks continue to develop using pure Action Script 3 (FlashDevelop) while others are creating custom components in FlexBuilder. How do the AS3 developers use the Flex Custom components built in FlexBuilder in their AS3 Applications?

I know it exists, because 1) the compiler had no complaints, and 2) I can trace property values of the custom component and get valid output from the trace statement.

Flash :: Flex Custom Component With More Inside?

Apr 14, 2012

I am creating a custom component in Flex with extends the BorderContainer class, and I would like to be able to place additional content within the tagset when I use it in my main application, like this:

<components:CustomComponent title="Hello">
<s:Label text="If you have one enter it below:"/>
<mx:Spacer height="15" />

[Code]....

This works just fine, except that my component definition had some additional things inside of it, such as a <s:Label/> and styling, which is replaced by the content within the tagset above when I go to use it.

If I do not put anything within the tagset, the content that was originally in the component is not replaced.

Is there a way that I can simply append additional content inside of the component when I go to use it, instead of it being replaced each time?

Also the mouseDown function doesn't work for MyCircle,but if have the event for the VBox, the Alerts are displayed.
