I have a label component in a mxml file like below
<mx:Label x="700" y="409" text="Label" id="lble" width="131" height="41"/>
if i want to access it and change its text content within a method defined in action script class that i have written, how to do it?
lble.text="test";
I've always just developed my projects in as3 instead of mxml and I usually just setup my application to run a main actionscript file as my main doc root, sort of like how you do it in flash but in flash builder I do something like this:[code] how can I call place a call to that function hitme() within the call_from_outside() function between the <fx:Script> tags?The reason why I'm doing this is because I have some flash swfs that I load into another swf file and I can access the top level public functions of those flash swfs, however the top level of the flash builder/flex swfs is the main mxml file not my fake as3 class root. Of course I should think there is a way for me to access the as3 class methods of the mxml component but for keeping things with the same structure, I can bypass having to modify my loader scripts.
View 1 RepliesIs it possible to access a declared component as an IFactory within an MXML class? I've used this style of declaring factories many times for Skin Parts, but I've never figured out how to access those factories from within the MXML.
Here's an example of what I would expect to work:
<fx:Declarations>
<fx:Component id="labelDisplay">
<s:Label fontSize="12" fontWeight="bold"/>

I am using flex builder 3.2, Action Script 3 and develop for Flash Player 10 and am quite new to it. when I call a method of a self defined class, I get the 1061 error (not defined). But the class and the method exist and are public, so what the hell am I doing wrong? Flash Builder is even offering me this method in the auto-completion, so at least the builder knows it... I have already tried cleaning the project (as this is the common source of strange errors when working with java/eclipse),
edit: solved... The problem was that a package had the same name as the variable I used for the class. Very strange error message, thumbs down for this .
i'm trying to access an mxml component from my external as file. e.g

i get the following error:

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 have two components. One is called "InsideComp" and one is called "OutsideComp". OutsideComp has InsideComp as one piece of its component, and in my main MXML file, I have embedded an instance of OutsideComp. How do I access a public variable of InsideComp within my main MXML file?In Actionscript, I could just do something like:OutsideComp.InsideComp.valToChange = 5; But I dont know how to do it in MXML. I know this is probably an easy question.

I've been trying to create a custom mxml component that extends another custom mxml component (i.e.MyMXMLComponent -> BaseMXMLComponent -> Group). I've been reading that trying to add visual children to MyMXMLComponent caused error with Flex 3 but that's no longer the case with Flex 4.
What I want to know is whether this is a supported/fixed/documented feature of Flex 4? or just some undefined behavior in Flex 4 that may get changed with future updates?
if this is supported and documented feature, does anyone have link pointing to adobe document stating it as such?
I'm trying to set the height of a vertical bar (activityBar) but it does not appear to do anything. i have tried something similar with the whole component, but setting the dimensions does nothing (even in the mxml used to instantiate the class). Indeed, I've added transparent graphics just to give the component some dimensions
FYI: I'm trying to create a mic activity bar that will respond to the mic by simply setting the height of the activityBar child (which seems to me to be more efficient than redrawing the graphics each time).
package components {
import mx.core.UIComponent;
public class MicActivityBar extends UIComponent {
public var activityBar:UIComponent;

View 2 RepliesI'm trying to do this using only mxml, no <script> tags, although I don't necessarily need a solution that's only mxml. It was more of an educational exercise to see if I could do it all in mxml. I have a custom component that has a slider and textinput and their value/text properties are bound together. I'm surfacing a few properties of the slider in my component so that it can sort of be treated like a slider.

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.
I have an MXML component that includes a .as file with
<fx:Script source="myfile.as" />
Running asdoc throws a whole bunch of errors like
"Error: The private attribute may be used only on class property definitions."
"Error: The public attribute can only be used inside a package."
Solution 1 is to move the AS code into the MXML file. Kind of defeats the objective of using external .as files for MXML components in the first place, so really a last resort option. Code inside a mxml file is messy (I really don't want logic mixed in with mxml), and would also require using the < !--- ---> asdoc syntax.
Solution 2 is to have the MXML component inherit from a normal class file. That would mean no private members in the base class, only internal (meaning a separate package for the component to be safe) or protected. This would make things tedious to say the least.
Are there any other work-arounds or possibly a beta/nightly version of asdoc that fixes the problem? I am using the Flex 4.1.0.16076 SDK, the "latest production quality release".
Update:Just tried using asdoc from the svn trunk, (4.5.0 rev. 16942) and the problem persists.

But when I try to access the public method parsePlayList in the CDN object in a method in the class defined in the .as file, I get the following error: Access of undefined property CDN The reason I want to do this is to break up the logic of my application into multiple AS files and have minimal MXML files, probably only one.
