I have a weird issue (weird because it is specific to one component) with applicationComplete in a fairly simple application. All the UI components are declared in MXML. I can access them all in applicationComplete, but not a spark.components.TextArea component, named taStatus here; it is null in the handler.[code]...
View 1 RepliesI'm working on an app that, from the Main.mxml, opens one or many Window.mxml instances. When it's done I want all windows to be chromeless so the custom controls need to work. In Main I've added applicationComplete="init();" so the init function gets ran, which contains clickhandlers, which makes the buttons work. However, this way of running an init function doesn't seem to be valid for an mx:Window. I can cheat by not using a clickhandler for the minimize and close buttons with a click="this.minimize();", but I don't know of a way like this to make the move work because it's a MOUSE_DOWN event.
Question 1: Is there a way to have such an init function in an mx:Window?
Question 2: What's a good way to make the buttons on the Window instances all work?

View 3 RepliesI have a component "child" which has a cancel button. Now this component is placed in a state called "newChildComp" I also have another component called "parent". In the parent component, i have a button that dispatches an event. Here is the event code:
[Code].....
so, basically,i am checking to see if the cancel button component in the Child component, while i am still in the parent Compoent, was clicked, if it was clicked, call the cancelButtonHandler. The problem is by the time the addNewChild handles the event, that cancel button was still null. My question is how do i solve this without using the itemCreationPolicy on the cancel button?
With the Flex 3 SDK you simply needed to set the borderThickness style to 0, or set borderStyle to none. With the Flex 4 SDK ad the Spark theme, this has no effect.

Is that because i used both applicationComplete and Initilize together ?
I am putting together a presentation on flex for adobe user group that specialize in coldfusion. In my example I would like to display the text of the cfc being called from the webservice tag in my flex application. Is there a simple way to load the actual text for the cfc instead of the html that coldfusion is passing back to my URLloader variable?

I googled for almost a day to find the answer to my question: [URL]. This almost works (and is a great solution), but the solution doesn't work when I do:
1). Copy and paste multiple-line texts.
2). Write long and scroll the texts.
I also found another working example at: [URL]. (The autocomplete prompt appears when you press ctrl+space right at the caret's position). But an email from its author says he uses monotype fonts to calculate individual character's location. Is there a way to get multi-line input from a textfield?
I'm working on a simple view in my app that allows a user to drag an item from a list control and drop it onto a textarea.
Seems the dragEnter event fires just fine, but the dragDrop event does not.
I have a TextArea that I don't ever want to be scrolled. When scrolling within the application that holds this TextArea, however, the scrolling stops as soon as the mouse ends up over the TextArea.
Is there any way to pass the scroll event to the application, or tell the TextArea to not claim the event?
I would like to disable copy event in the TextArea I'm using. To achieve so I added the following code block:
function initTA(){
var tf:IUITextField = body.mx_internal::getTextField();
tf.enabled = false;
}
<mx:TextArea id="body" creationComplete="initTA()" .../>
This is working fine unless the text area has lots of text inside in which case a scroll bar appears. After the scroll bar is being used by the user, the text area stopped blocking the copy event.
By the way, I am using text area for display purposes since I use rich text area format.
Every time a user takes a new line (i.e each time they press the return/enter key) when typing in a textArea, I would like the textArea to dispatch an event.I can then listen for this event and then carry out some processing on the textArea's contents.
View 2 RepliesI'm using Flex 4.5.1 with AIR 2.7 (and Flash Builder 4.5.1) to build an app for the Blackberry Playbook.
The app has a large textarea that needs to be resized when the soft keyboard shows up. I am able to hook into the soft keyboard events and do things there.
Now, I want to resize the textarea to fit the remaining part of the screen when the keyboard shows up. I know the current and destination size and want to use a smooth animation to show the textarea resizing. (I can't already set the height and can see the textarea being correctly resized in the keyboard_activating event - but I want to do it through an animation). I've tried using the Animate class, the spark.effects.Move class and none of them seem to work in this case. They seem to run the animation but the screen does not get refreshed!

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
<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?

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 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'm just getting started with custom events in a custom component. And I don't quite have the hang of it, yet. I've got a component with a button in it. When it's clicked, I want to call a function in the main app.

I have an application in flex, it has some components out of the box and quite a few of custom components and events. I want to get all event listeners on a specific component in runtime, I know how to do it with monkey-patching the framework but I do not want to use a monkey patch nor can I rely on this in production.

What's the call analogous to creationComplete that happens every time a component is rendered? I want to rerun a function every time the component gets rendered (it has to make an HTTP request, but the url it calls changes each time) and I can't figure out how to do it.

enter code hereBeen really frustrating just trying to load a swf from a swfloader in Flex and then accessing it's content. I'm sure once I figure out how to do it once then it'll be fine, but I've gone thorugh a bunch of tutorials and somethings not right. Here's my flex code:and the as code:
public function initHeaderSwf():void
{
trace("INITIATIED");[code]........
Here's the problem: The swf loads, there is no problem there.i see it in my compiled swf. but the complete event doesn't fire. CreationComplete will fire, and then I try, after that, to make a event listener for loading the actual swf, that doesn't fire.I've tried it a variety of different ways with no luck.All I am trying to do is change a text field in the loaded swf.I imagine this might be a problem with the sequence of things loading or something like that, but not sure.
I have a CustomTextInput component based on TextInput (Spark) component. The instance of this class is placed on a popup window (TitleWindow). How can I capture the popup move (dragging the title) event inside CustomTextInput implementation?
MoveEvent.MOVE event of the CustomTextInput itself doesn't work. Of course, I can't access the parent popup window inside the component implementation, because it's a common component that can be used not only on the popup windows.
I have a custom component with a couple of text input fields (among other things) that is used as the row components in a tree. I have had to write my own drag and drop handling, and have almost finished the start handler (which I did last), using mouseDown as the event to kick if off.It basically works, but when the tree is expanded enough so that a scroll bar shows, using the scroll bar drags a row of the tree at the same time ! Not the desired behaviour.Looking in the debugger, I can see that when a row of the tree is dragged the currentTarget is the tree itself, and the target is the textInput component. Looking at the parents of that component I can see my custom component (that contains the textInput) a couple of levels up.My question is, is there an easy way to determine if this target is descended from my component, so that I can initiate a drag only if that is the case ? event.target is doesn't work by the way.
View 2 RepliesI 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.
It uses a focus_out event to detect if there is a change that needs to be committed. However I notice that a FOCUS_OUT event is only called if you click away from the textfield but inside the component. Is there any way I can listen for clicks outside the component from within the component?
addEventListener(FocusEvent.FOCUS_OUT, onFocusOut);
protected function onFocusOut(event:FocusEvent):void
