Flex :: React To Change On A Static Property?
Jun 1, 2009
I'm re-writing an MXML item renderer in pure AS. A problem I can't seem to get past is how to have each item renderer react to a change on a static property on the item renderer class. In the MXML version, I have the following binding set up on the itemenderer:instanceProperty=callInstanceFunction(ItemRenderer.staticProperty)What would be the equivalent way of setting this up in AS (using BindingUtils, I assume)?PDATE:So I thought the following wasn't working, but it appears as if Flex is suppressing errors thrown in the instanceFunction, making it appear as if the binding itself is bad. indingUtils.bindSetter(instanceFunction, ItemRenderer, "staticProperty");However, when instanceFunction is called, already initialized variables on the given instance are all null, which was the cause of the errors referenced above.

Can we put [Bindable] on functions/methods? I know that bindable is used to change the value of the source property to destination property. But not sure if we can use that for methods. why we cannot put/ if we can then what will be the outcome?

I have a large block of code in frame one of a movie. It executes, then the movie progresses to frame 2 and stops.I then have buttons at frame 2 that change the value in a string variable and send the movie back to frame 1 where it executes the code with the new value and proceeds to stop in frame 2 again.How can I eliminate this use of frame 2?How do I set it up so that I just re-run the code when the variable changes?I assume I can put all my code inside a function that gets called when the variable changes.

But I get an error for "selected" property that i used in my checkBox. the error says :
Access of possibly undefined property selected through a reference with static type TrashContainer_inlineComponent1.

I need to create a static frame and a changing content... currently envisaged as frame containing the side panel and header and footer content.
The content panel will call mxml based on the content sought.
a) how is the frame paradigm- with static frame "containing" other content done. I dont want to repeat the header and footer logic in every 'content section' code?
b) how is the hyperlinking between content sections done- using 'states' seems convoluted

Let's say I have about 100+ buttons. They all have the same label. Now I want to change the label for all with a click. I could give them IDs and then run a for loop, but I'm searching for a neater solution.[code]...

I have a custom component on which I have bound an array collection to one of its proeprties: <comp:MyComp id="comp" prop="{images}" /> images is an arraycollection In the components' code I would like to know which event to listen on everytime images updates props. I tried a setter on props but the setter only gets called once when props is first set. I tried the collection event but I get "Update" events sent on top of 'add' and 'remove' events and I would rather not have to manage those. So is there an event(flex or otherwise) that is fired every time a component property is updated by a bindable property?

On creation complete my parent component executes an "init" function which simply sets public bindable variables in child components. I'd like the child components to watch these variables and upon being set use them. However, for some reason the ChangeWatcher is not firing with the change of the variable. Below is my code;
Parent Component
private function init():void
{
userInfo.user = new User("Tom");

I've got a component called Box.as that has following two properties, and have their getters & setters defined:
private var _busy:Boolean;
private var _errorMessage:String;
In MXML that uses this component I define it like this:
<components:Box skinClass="skins.components.BoxSkin"
busy="{presenter.boxBusy}"
errorMessage="{presenter.boxErrorMessage}"/>
Where presenter variable is defined here in MXML and a Presenter class has boxBusy and boxErrorMessage variables defined as bindable property change events:
[Bindable(event="propertyChange")]
function get boxBusy():Boolean;
function set boxBusy(value:Boolean):void;
[Code]....
PROBLEM is that whenever I change boxErrorMessage for the presenter, I see the affect in MXML but nothing happens at all when I change boxBusy. Is there something extra I need to do with boolean variable?

I have a prompt string to be displayed in my combobox - this needs to be displayed in italics. When user makes any selection from the list - i need to change the style of the displayed content.
My css file:
.promptStyle
{
fontStyle: italic;[code].....
I am able to see the style change happening because the color changes; but the change specific to textInputStyleName does not get applied.

How can I enable or disable a group of components in flex (flash builder 4)?
For example, if I have a window with several fields, I want to disable them based on the users permissions.
I know I can add the enabled="true" or "enabled="false", and I can also use enabled="{writeAccessVar}"
However, I am looking for more ideas, as I might have more than one group of fields on the screen, or more complicated user permissions.
For example, I will currently have one field with write access, the other fields on the screen read only for a certain user level.
For a higher level user, all fields are writable. Lower level, all are read-only.

The behaviour looks little weird for me and dont know how to get valus through static property from an array:
[Code]....
but if I initialize missions with values not in the construtor but through variable initialization I gets output = 4; why is that? Doesnt static class initialize its variables in the constructor statement??

I'm trying to change a static variable in the class's constructor. At the start I have:
public static var mainReference:Main;
public static var timerReference:Timer;
public var timer:Timer = new Timer(1000);
This is so my static functions can access main and timer. At Main's constructor I have:
mainReference = this;
timerReference = timer;
The problem is, the first gives no error when I compile it, but the second tells me Access of undefined property (timerReference).

I have a set of classes that I've been using in one Flex program (Classroom). I just created new project and referenced the source path of the first program's com directory in its build path.
When I do an import, import com.cade.comm.CADEports;, everything looks good. When I use a variable in the code, CADEports.gotComm = true;, it still looks good. However, when I try to run it, I get an 1120 error that says "access of undefinded property...".
In the main program:
Flex Build Path -> Source path = ${DOCUMENTS}/Classroom/src/com
import com.cade.comm.CADEports;
...
CADEports.gotComm = true; // compile error here although when you type CADEports. it shows the gotComm variable!
[Code].....
Why does this work in the original program but not the second?

I have declared some public static consts within a class Instrument. So that I can hopefully access them like Instrument.SAX, instrument.HARP, etc. etc. But when I go to trace out or compare the consts, it gives me this error:

Error: Access of undefined method getStatus through reference with a static type Class.
Here's what's happening in the code. I'm trying to create a User class that is instantiated at the start of my app. I want the User class to have properties like mainStatus, with helper methods like setStatus etc. Pretty simple.
so on my HardDisk I have my flash_working folder with all my flash projects. I created my class file/package under the directory com.mypackage
[Code]....
That's all the code I have.
If I try to access the public var mainStatus through user.mainStatus that gives a similar error saying:
Error: Access of undefined property mainStatus through reference with a static type Class.

I have the following code:
var myPercStr = myStr.text;
myPercStr= myPercStr.toString();
var myPerc = Number(myPercStr);
I am trying to get the value of a text field which is created by the user pushing a pin-pad. This text field is a string which is joined() from an Array of the sequence of pin-pad entries. Now my problem is that Flash will not convert the .text text field into a string with which I can use the value to convert to a Number and perform math on it.
