I have some MXML elements which i would like to remove and add to a parent element. Unfortunately I am constrained to removing the MXML object as this is handled by the custom component. So is there any way to reinstate a removed MXML element back into the display list?
View 1 RepliesWhen adding/removing elements to/from a VGroup I need it to happen smoothly, resize the item. I believe I have to use transition effects. But how?
At item (element) level? At VGroup level? Should I use a DataGroup instead and do it at ItemRenderer level?
I've been trying to do it at item level but I still didn't manage to make it work and somehow it doesn't feel right. It feels like it should be done at a higher level.
For example, I defined a "death" state which resizes the item to height=0. But then, after it shrunk, it has to somehow notify VGroup in order for it to be removed or remove itself from VGroup. It feels unnecessarily complicated.
way to associate an effect to inserting and removing items from a VGroup?
Anyone know if there's a way to check for objects in memory that have been removed from a display object but not set to null?
View 1 RepliesIf I wanted to do something like this:
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml"
horizontalScrollPolicy="off"
verticalScrollPolicy="off"

How would I get a handle on myCanvas (where I'd want myCanvas to be the root )?
I am using this collapsible panel - link. Unfortunately, I have a problem using it with application states. I have a state where this panel is visible, when I switch to this state, this panel shows, when I click on it, it opens and its content shows. If I switch to another state (this panel is removed from display), and then switch back to the previous state, the collapsible panel stays open, but its content disappears. In other words, the collapsible panel's content doesn't persist through states. Anyone know what the problem is? Or is there another collapsible panel that can work around this issue?

View 1 RepliesI'm working with some mxml that I'd like to see how it looks like in actionscript. It's a popupAnchor that just has a custom view called HTMLWindow. The custom view is basically nothing but an mx HTML component <mx:HTML>

I'm trying componentize one of the pieces of UI in an AIR application that I'm developing in Flex. In this example, I want to display file information on a single line (which has an icon, some text/link and the size).
My code looks like this (component is called FileDisplay):
<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="[URL]"><mx:Script>
<![CDATA[
public function set iconType(source:String):void {
this.ficon.source = source;
[Code] .....
However, when I do this, I get an error: Error #1009: Cannot access a property or method of a null object reference. This is because the child components of the FileDisplay are null (or at least they show up that way in the debugger). Am I supposed to be waiting for events indicating the child components were created? For now I can manually do everything in ActionScript in my main app (create a Canvas and add children to it) but how to separate the code more cleanly.
Let's say I have an interface
public interface IFoo {
...
}
[Code]....
and have it be instantiated at runtime by a factory.
However, the compiler won't let me do this-- it's trying to do "new IFoo" in the generated ActionScript.
How to get around this? How can I use an interface and a factory purely in MXML?
If I do something like:
<myComponent id="foo" title="bar" />
The parameters don't seem to be available immediately within the component. When do they become available?
I have a Flex XML object as follows:
private var _xmlCountries:XML =
<Countries>
<option value="AF">Afghanistan</option>
<option value="AL">Albania</option>
<option value="DZ">Algeria</option>
<option value="AO">Angola</option>
[Code]...
This object is ok, and shows up correctly in debug mode. The problem is I have a country name i.e. private var _country:String = "Angola";, and I want to get the corresponding value 'AO' from the XML object. Do you know how to do this?
I have tried loads of Livedocs examples, but cant get it to work. P.S. I am working on a HtpService & WebService driven app to display global weather conditions overlayed on a Google Maps interface. Going to make it available to the Flex community when finished.
I have extended an mxml component with an actionscript class. I'm trying to access a component in the mxml file using the id (in order to add an event listener) but I cant seem to do it.
I get:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
Does the impact of event listeners on resources persist after their targets are temporarily removed from the display list? What about when mouseChildren is set to false for their container?
View 1 RepliesDoes MXML get compiled down to as3 and then converted to flash bytecode? Also, is there a significant performance penalty to compiling mxml vs compiling as3?
View 3 RepliesI am working on a custom Flex 4 component which is an aggregation of two existing flex components. I would like to be able to specify my own custom properties for the component as well as access the existing public subcomponent properties via MXML.

If I create a rectangle with 100px width and 100px height and then rotate it, the size of the element's "box" will have increased.With 45 rotation, the size becomes about 143x143 (from 100x100).Doing sometimes like cos(angleRad) * currentWidth seems to work for 45 rotation, but for other bigger angles it doesn't.At the moment I am doing this:
var currentRotation = object.rotation;
object.rotation = 0;
var normalizedWidth = object.width;

I have two FLV files playing on the stage. The main FLV is instance is: MyVideothe 2nd is MyVideo2I have imported the videos using the wizard. The 2nd video is just a movie I created in Affter Effects that says...loading please wait....this is a really nice video and I don't want it to just use a standard preloader. Anyway, the goal is when the playback for "MyVideo" begins I would like "Myvideo2" to = visible = false;I have tried this many different ways and have been unsuccessful. I am obviously a newb at this. Also, does anyone know where I can get a list of all available eventListener actions...etc?
//var nc:NetConnection = new NetConnection();
//connection_nc.connect();
//var stream_ns:NetStream = new NetStream(connection_nc);

The problem is with smallImg_mc. Later on when it is clicked, it gets removed using the removeChild(smallImg_mc) command, and my question is how do I signal it through an if statement where it says
if (smallImg_mc.visible !== false) {
setChildIndex(smallImg_mc,1);
setChildIndex(logo,1);
}
It's causing annoying output errors.
