I know that preloader is the first piece downloaded and it will load the large part of the swf. I want to know the progress of the large part downloading, and for simplicity I don't need UI to display the percentage, the data will be passed to HTML, HTML will handle the UI.
Is there any easy way to get the preloader event in flex? Without adding a lot of code in flex?
We are trying to automate our flex application. After adding automation libraries to our project we get the following exception:
TypeError: Error #1009: Cannot access a property or method of a null object reference.

We are using Flex 3.4 and maven2 to build the application.
Below is the overriden on complete function for a preloader in Flex.
private function initComplete(e:Event):void
{
//dispatchEvent(new Event(Event.COMPLETE));
cp.status.text="Configuring... Please Wait";
}
What I want to do is when the app has finsihed loading I want to change the preloaders text to "configuring".Then I want to go and do a bunch of setup stuff in my code.Once I've done all the setup I wanted how can I get the Preloader to dispatch its Event.complete from else where in my code?I tried Application.application.preloader but it comes up null.So I guess my question really is how to access a preloader from anywhere in my application. Would a better approach be to have all setup classes as members of my preloader class?
I have a AS spinner class that I downloaded from Jake Hawkes (click here to see it running).I want to replace the flex application preloader with this spinner. I have previously used custom preloaders, but that was just for editing what already existed. Anyone know how that spinner.as could be used instead of the loading bar?
EDIT: This is the extremely cool custom preloader that Im going to try to edit (it extends Sprite) view source enabled:[url]...
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;

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.
View 1 RepliesIf I create an object like so:
class Foo {
[Bindable] public var property: String;

The class Foo has an implicit event dispatcher to handle property change events. How can I access that without making Foo explicitly extend EventDispatcher?

I have a textfield in flex with a focusOut event on it. I can type in the box and in Firefox and Chrome when I click elsewhere on the page (outside the flash element) the focusOut event will be triggered. However in IE8, the texfield never loses focus when you click elsewhere on the page, outside the flash object. I've tried with focusManager.browserMode set to true and false with no difference (I believe that effects incoming focus anyway).
View 1 Repliesoverriding clone() while creating custom events?I read in the Flex cookbook that we need just in case we want to redispatch this event. Does this exactly means that when we want event to be bubbled up the display hierarchy , at that time our custom cloned event should be dispatched and not the Event object.
second - whats the need of metadata tag -
[Event(name="modelEvent", type="com.abc.data.model.ModelEvent")]
public class LoginModel extends EventDispatcher
I understand we need to extend EventDispatcher in case we want to dispatch evnet from class.. but In what cases i would need to specify the MetaData TAg
Third is.. If i write -- "dynamic customEventClass extends Event".. Is there any use of Dynamic i can make?
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 using modules in flex, to build different parts of my webapp. What I need now, is a way these modules can communicate with each other on events. What really is happening is ,that there is a central module, which then will take care of loading other modules and passing data to and fro. But, coding for each part to delegate events to each of these loaded modules from the central module and back would be a big nightmare.
What I really want to do is have a global event bus for it. Are there any specific libraries, already existing for such a process. Also, I would be using MVC, so it should also take care between events form the model to the view and vice-a-versa.
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.

View 1 RepliesI 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
<fx:Metadata>
[Event(name="refreshPreview", type="flash.events.Event")]
</fx:Metadata>
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.
<s:Group id="contentGroup">
<s:Group id="formGroup">
<s:Form x="11"
[Code]....
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()
in flex application i have a button and two functions in action script. wat i wan is when i click the button it has to call a function and Abort and call another function simultaneously.
View 1 RepliesFor some weird reason the preloader for my Flex 3.5 application does not show up. The application SWF is around 550KB. Am not using RSLs. From the Activity tab in Safari I see the progress of the SWF loading in the browser. After the SWF is loaded. The preloader comes for a split second, moves from 0 to 100 and goes away.
View 1 RepliesI have been digging for custom Flex preloaders and they all seem to rely on the same template:An SWC is created with Flash CS5 and then used by Flash Builder using the "preloader" application property. I don't own Flash CS, and it feels that Flash builder should be able to do the trick. I created a Library Project in Flash Builder with the following bare bones code:

I have created a Flex custom preloader, exactly like it is done in this example: [URL]
Now when I implement this, is seems to work fine on my computer in FireFox and Chrome. I publish it on the server, refresh my cache and reload the application and I do get my customized preloader.
But on a friend's computer, the screen stays white for a while, and then for a second or so it shows the preloader, but the indicator is at 100%.
So the loading already happened before it showed the preloader.
I'm watching this video, which is pretty goodhows how to inherit from DownloadProgressBar to create a customer preloader for your flex app.TheDownloadProgressBar class has an overridable getter for the property 'preloader.'

I am writing a custom flex preloader which extends the IPreloaderDisplay class. How can I load the images from web in my custom preloader?
View 2 RepliesI would like to track the customer experience in downloading and initializing my flex app.
(a) Is there a way to pass data from preloader to the application? I would like to pass the time it takes to download and the time it takes to initialize.
(b)Alternatively: Is there an event at the application level that corresponds to the preloader events:
1. Download complete
2. Initialization complete (same as Application creationComplete)
I'm working on a little project in Flex that's an application to upload images to a server. Since it's a pretty lightweight application (~40 kb in release version), I would like it to display instantly when the html page is loaded. But somehow there's a delay of up to 1-2 seconds before it shows up. I think it is a delay actually between the load and the display of the application, and I believe it could be removed.
how to shorten/remove the delay. First, I tried to disable the preloader, but this did nothing. There's actually a delay between a preloader shuts and the application displays (it is around 500 ms - 1 sec). My next guess was to write a custom preloader class to display at least an image of the application (even though it wouldn't be clickable, but at least something).
I have a custom preloader that I designed in flash. When I load it in flex, it loads with a white background. When I try to change the background to black in my flash file & load it in Flex, the background color remains white. I've also tried to update the compiler settings in Flex, adding "-default-background-color #000000" but I still get a white preloader background. I am using Flex 4. Here is my Pre.as file:
