I am trying to override the text setter in the Label component but it behaves weirdly sometime super.text works and sometimes not! and the traces show that there's no error with my code.
here's my code:
import spark.components.Label;
public class LabelXX extends Label
{
private var _initialText:String;
[Code]....
super.zValue(n) should be super.zValue = n ........ wowy Nothing to see here folks, just keep moving on I'm having some difficulties in working with the as3 way of overriding methods.. specifically setters. I'm a recent convert from working with as2 for a few years, so some of these quirks are beyond me right now.Here are my two classes:class tempBase in package core
Code:
package core
{
import flash.display.MovieClip;
public class tempBase extends MovieClip
[code]....
I do not have any errors for the override of baseFunction, but on compile I get the error 1061: Call to a possibly undefined method zValue through a reference with static type core:tempBase.In as2, this would have been perfectly acceptable (even without the override function), and was incredibly useful in creating my class structures.
I 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. For instance I might want to adjust the font color or style for the label and text input. toy component which aggregates both a label and a text input:
<?xml version="1.0" encoding="utf-8"?>
<s:Group xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
[code]....
What I'd like to do: create an MXML component with some children, then extend it via MXML to create a new component with more children, without losing the original set.In other words
create a component bc.mxml
<?xml version="1.0" encoding="utf-8"?>
<s:BorderContainer xmlns:fx="http://ns.adobe.com/mxml/2009"

Is it possible to make some kind of 'dynamic' thumbnails for mxml components which I'm using in my application? By 'dynamic' I mean if I change some layout in mxml component, my thumbnail refreshes according to new layout without any screen capturing,photoshoping or similar
View 2 RepliesMy Main.as extends flash.display.Sprite, I want to use a ComboBox component in the as, without any mxml, how to implement it? I read this Possible to use Flex Framework/Components without using MXML?, Its main as extends spark.components.Application, but still need a mxml file. Its main idea is to rewrite the Application component, and reuse it in mxml file. That is not what I want. I uses Flex SDK 4.1
View 1 RepliesI'm working on an AIR project in Flash Builder 4. My question has apparently been asked a lot (according to Google), but I haven't found a satisfactory answer so I'll be very detailed in what I'm looking for:Is there any way to create an AIR project in pure ActionScript that:Is truly object-oriented (i.e. the entry point is an ActionScript class with instance variables and methods)?Can instantiate mx and spark controls without MXML?I was able to accomplish #2 in fairly different ways by following these two sets of instructions (with only a tiny bit of initial MXML):
[URL]
However, neither of those allows me to accomplish #1. If I declare a private member variable outside the entry point function, I get an error from the compiler that the keyword 'private' can only be used in a class.If you like MXML, feel free to post your viewpoint as well. My reservations revolve mostly around these perceived notions:The learning curve of MXML seems steep.The time it will take to become good at MXML will not be worth the investment since its main purpose is to ease GUI development (which I'm already good at anyway).Like I said previously, I don't want to be an "XML programmer". I'd like to maintain the power and flexibility of OOP.
I have several mxml components in an app, all of which need the same variable called genericX. I've included that variable in the main mxml and made it public
[Bindable] public var genericX:Number = 102;
But I still can't access it from other mxml components. If I try to do this for example, it doesn't recognize the variable.
<s:Button x="{genericX}" label="Click" />
When I define custom propertie in my MXML component, I also want to define a set of possible values of that property to make Flex Builder show then (possible values of the custom property) when I invoke code completion function.

View 2 Repliesim trying to figure out what is better for run-time, creating components in MXML or by SCRIPT?. I built an app that recieves data from a server without knowing how much data exactly. In worst case scenerio , ill need 10 LABELS and 2 DATAGROUPS.But i usually need something like 3 LABELS and 1 datagroup. what is better? creating all components in advance and than not include in layout the ones i dont need, or make some checks and then create only the components i need by script? I made some tests , but it wasnt really decisive, run-time was pretty much simillar.Im guessing it must be stated somewhere what is better. Does anyone have an answer for me?
View 1 RepliesI'm playing around with the scaleX/Y in the canvas tag and have noticed some strange behaviour. When I set scale in in mxml the width and height of the canvas are adjusted accordingly. For example if I have a canvas like this: <mx:Canvas width="1000" height="1000" scaleX="0.1" scaleY="0.1" />
The canvas now appears on screen to have a width and height of 100 and if inside my creationComplete callback I check the width and height property they are indeed 100. But if I do exactly the same thing except I set the scaleX/Y property from actionscript the canvas on screen appears to have a width and height of 100 as expected, but when I check the width and height property of the canvas they are still at the previous values of 1000.
I'm implementing a Flex application with several modules.I'm reusing the same component in all these modules.I was wondering if I'm correctly importing it in each mxml module definition: xmlns:hillelcoren="com.hillelcoren.components.*"Should I import it only once, in the main application mxml instead?
View 1 RepliesThere are lots of examples of how to create skinnable components in AS3 using the new Spark component architecture, however I've yet to find any such examples using MXML.What I'm mainly referring to is defining the skin parts and skin states. It seems as though the SkinPart metadata is supposed to be associated with properties and as such can't be used in MXML, is this correct?

How to add Column to Adobe flex mx:DataGrid in mxml and/or actionsctpt?
(You can put this code in Flash or AIR app - it will compile with no errors, but will not add any columns=( )
I am attempting to implement a layout in Adobe Flex 4.5 / MXML where I have multiple controls in an HBox that - in total - consume all available horizontal screen estate. Some use a relative with (percentage), some an absolute width (pixels) and one is supposed to consume whatever space is still left, such as:
+----------------------+-----------------------+------+
| 35% | fill parent | 10px |
+----------------------+-----------------------+------+
How would I achieve this in Flex (is there something comparable to Android's
layout_width="fillparent")?
Due to the fact that there are elements that have an absolute width I cannot easily calculate the width of the filler as a percentage a priori (as it varies with the screen width). Setting the filler's width to 100% also does not work as this will shrink the 35% area below 35%. Applying the updateDisplayList suggestion from www.Flextras.com's answer below yields the error "Call to a possibly undefined method updateDisplayList" at the line marked in the source excerpt below:

I am working on an application where I need to basically have 2 separate screens and I need to be able to switch between them. I am a total noob to Flex & Flash and I have not found anything on how to do this in my 2 days of Googling. It really shouldn't be this hard to do!
Here is what I have tried. I created a Flex Project and added 2 MXML Component files called Test1 & Test2 and each simply have a button in them which have a label of Button1 & Button2 so I can see if the correct component is showing. Below is the button code in the Test1 MXML Component file[code]...
I'm writing a Flex application using Flash Builder 4 and I'm having a bit of trouble with an AS3 object.Essentially, it is a BorderContainer, with a few buttons and images, and programming logic that determines how these interact with eachother and a database.
What I want to be able to do is configure the layout/style of the inner components using MXML and CSS. I can configure the inherited objects, but not ones that I have defined.[code]...
Does 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?
