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 RepliesI 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

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()
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

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 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 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.
View 3 RepliesI 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.

I have a datagrid with one row intially. When I click on the first row, i.e on key down event, I want another row to be added. Earlier I had a button, on clicking which I added the row. But now I want the row to be added automatically once I click the first row. How to do that?
I added keydown event to the datagrid, but it threw some error.

View 1 RepliesWhat is event bubbling in Flex?
View 1 RepliesActually I wanted to know what is bubbling event and how to make use of it. Also, what is the concept of capturing, targeting and bubbling too?
View 2 RepliesI would like to know if it's possible to add some jobs on the onload of my air app, what I mean is: I have an eventHandler which get the event "FlexEvent.APPLICATION_COMPLETE" but this event it`s dispatched after the progress bar ends, I would like to know if there is some event that I can handler and add my jobs there?!?
Or the only way to do this, it's doing a custom preloader??, like the link bellow:

I use a custom component for painting a graph on a canvas, now when the windows is resized I want to determine the actual width and height of my canvas to resize the graph as well, therefore I used the resize event I can use in mxml.Now I detected in my method for resizing I only receive the width and height of the canvas just before resizing not after. When grabbing an edge of my window and moving it slowly for resizing this does not matter but when maximizing or minimizing the windows, this plays a more important role.
View 1 RepliesI'm testing some event dispatch code in a Flex app, using FlexUnit's addAsync method for testing that events are dispatched. Great so far, I can ensure that at least one event was fired. However, I want to be a bit more detailed; I want to ensure that exactly the set of events I'm expecting are dispatched. Is there a useful test pattern (or, even, different test framework -- I'm flexible!) to accomplish this?I tried this code, but it doesn't seem to get invoked the second time:[code]
View 2 RepliesI'd like to arrange things so that I have a chain of keyboard event handlers in my flex application, all of whom are queried when key down events occur. Basically, when a visual component is on screen, it is a candidate for handling a key press event. Something like this (clearly this is pseudocode):
<application handles_keys="F5, F6">
<tabGroup>
<tab1 handles_keys="pgup, pgdn">
<control handles_keys="0,1,2,3,4,5,6,7,8,9" />

I have a class written that will respond to the key events the way I want it to, so how do I register one or more instances of this class to have the results I want? Also, note that there are some situations where this class should receive events that would ordinarily be handled by a UI component. The TAB key is the main example; I have a few cases where I want my key down event handler to fire even when the focus is on a text field.
