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 was wondering, if you have multiple components files that uses the same child component (but with slightly modified parameters), is it possible to assign that child component an ID with a String Constant?[code]...
View 1 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. 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"

I am trying to override a Button class, i have a few properties which i wish directly initialise with the mxml description of the component, like :[code]which function is triggered ( in order to override it ) when all properties with mxml description is fully initialised with their values ?
View 1 RepliesHow do you add an XML declaration - < ?xml version="1.0" encoding="UTF-8"? > - to a Flex XML object? The same thing you could do with the old XML - new XMLDocument class and the xmlDecl property.
View 1 RepliesI have been struggling to find a way to do this. Basically, I am committing data to a database that I have assigned all the variables to. However, when it has finished committing that data, I want it to then push to the next view. So far, I can get it to work if I program in another button to push to the next view but I want it to be automated with the one button.
So far my code is:
protected function btnClientSubmit_clickHandler(event:MouseEvent):void
{
repID = RepID.toString();
CompPass = CompID.toString();
[code].....
It works 100% for committing so that is not a problem and hence I did not include all the other code. My problem comes with the fact that the program is pushing to the next view too soon and it interrupts my data insert.
I have an object which is assigned a number of properties:
var project_array:Array = [];
var slideObject:Object = {
project_title : myXML.projects.project[i].title.toUpperCase(),
[Code].....
but I'm not quite sure where to place this. If I place it outside of the object constructor, I get "term is undefined", I guess because it doesn't know what project_clips_array is - but if I declare project_clips_array in the constructor, it appears to need to be defined, i.e. I can't create a blank property. But I can't place it in the constructor either, because it doesn't seem to allow me to run a function within an object constructor. What is the proper syntax or arrangement of code for executing this function to get the array within the object?
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?
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 RepliesI want to create a function pointer object:
private var func:Object = { Class.Constant: function };
What is the clean way of doing this? I did the above and got
Error: Syntax error: expecting colon before dot.
And I'm not even sure that's right. The goal is that I can just do
func[ Constants ]();
Lets say I want to call a function with an optional Object, how do I write that?If it was a String or a Number or some simple data type it would be:
Code:
function foo(s:String="Sample String", n:Number=100):void{}
But anything I try with an Object just throws an error. For example...
Code:
function foo(o:Object={x:10, b:10}):void{}
...makes the compiler barf, and so does every other version of this I've tried.
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.
I have written "components" in external .mxml files like dialogs and such. For example, GamePropertiesDialog.mxml. These components are used by another file, Main.mxml for example. If I instantiate a GamePropertiesDialog I am unable to access its pieces like a textbox with an id of GameName until AFTER I add the dialog to the display list.Doesn't work:
Actionscript Code:
var tmp:GamePropertiesDialog = new GamePropertiesDialog();tmp.GameName.text = 'test';addChild(tmp);
Does work: Actionscript Code:
var tmp:GamePropertiesDialog = new GamePropertiesDialog();addChild(tmp);tmp.GameName.text = 'test';

View 3 RepliesI have following data[code]...
AdvancedDataGrid does not displays properties of nested User object, but the simple DataGrid does.
In order to send a POST request I need to enumerate all properties of a given object. This object may or may not be dynamic. I'm looking for the most elegant solution. This is what I've got so far:
[Code]...
I'm doing some Actionscript work right now and I'd like to know whether there's a way to initiate an empty object's value programatically like this:
var myObj:Object = new Object;
myObj.add("aKey","aValue");
To add a property called aKey whose value is aValue.I need to create a "Dumb" (data-only) object to use as a parameter to send via POST. So I don't know offhand how long and/or how many attributes it's gonna have.
i'm attempting to cast an object's property as an actual property of another object. here's my object variable: var propObj:Object = {prop:"width", width:50}; now i want to assign the property of a sprite using that object's properties. var sp:Sprite = new Sprite(); sp.(propObj.prop as Sprite.property) = propObj.width; now, i'm not even going to try that because i know the compiler will explode all up in my face. but you should be able to see what i'm trying to do. why i'm trying to do it is because i'm reading in an XML file with an undetermined list of usable properties for specific objects. so instead of writing something like a huge switch statement to evaluate whether the XML file has a value for that specific property, i'm trying to assign properties dynamically based on what's available in the XML file. if what i'm trying to do is possible, what's the best way to do it?

View 2 RepliesI forgot to put it in the title so I'll just place it here; I am using AS 2.0. I know that there are other ways to accomplish the goal that am after, but I was wondering if anyone knows of a way to access the properties of an object's properties?
Here is the code that I thought of, even though it doesn't work
var a:Object = new Object();
a.bproperty = 0; //lowerlevel properties
a.cproperty = 1; // lowerlevel properties
[Code].....
This really just boils down to how I am organizing the code(I have ideas on what do next, and i am 99% sure that I can get them to work), and if there is a way to dynamically access the properties of the objects properties, It will save me from creating yet another large block of code for my project. If you want to see the unfinished project, go to [URL]
main.mxml
[Bindable]
private var _dp:ArrayCollection = new ArrayCollection([

I'm building a Flex/Flash Builder 4 application that loads data using E4X/XML, like this:I originally build an application that was a single MXML file which loaded this XML file and built a form from the data.I've now build a main menu screen with a button to load the form screen as a seperate module. How do I get the XML declaration to work in this module without loading it again.
View 1 RepliesIn Flex you can use Declarations tags fo non UI elements.Problem:The order of classes inside the Declaration is sorted ascending or something...Meaning that in this example, AClass will be instantiated before BClass:

eg. of mxml componet may be as simple as button label or text as complex as repeater whose data provider is a web service ( means a fresh quesy should be made to pull the data and refresh the dataprovider of repeater )

suppose i have 3 buttons(for example say, productin, marketing, sales ) on my main.mxml..once i click on one button it should take me to abc.mxml page with production data, once again if i click on second button it should take me to the same abc.mxml but with marketing data. same as for 3rd button also, how can i achieve this ?
