RE: [flexcoders] Localization in Actionscript file
Not able to achieve this. Why not? One simple solution is just to have a resource in your .properties file that looks like this: ComboList=Item 1,Item 2,Item 3 Use getString() and split() to turn it into the array [ “Item 1”, “Item 2”, “Item 3” ] that you can use as the dataProvider of the ComboBox. - Gordon From: flexcoders@yahoogroups.com [mailto:flexcoders@yahoogroups.com] On Behalf Of sony antony Sent: Tuesday, November 06, 2012 2:26 AM To: flex coders Subject: [flexcoders] Localization in Actionscript file Hello friends, I have a scenario like I need to implement localization in actionscript files.

RE: [flexcoders] setStyle, preinitialize and initialize
Doing it in the 'initialize' event seems like the right way to do it. The 'initialize' event still occurs before the LayoutManager has sized and positioned the children. But if you wait until creationComplete() the LayoutManager has already laid out the children and calling setStyle()will force another layout. Gordon Smith, Adobe From: flexcoders@yahoogroups.com [mailto:flexcoders@yahoogroups.com] On Behalf Of flexwdw Sent: Wednesday, April 11, 2012 3:40 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] setStyle, preinitialize and initialize So, I've run into this before but I don't recall it being the headscratcher it has become today I'm using Flex 3.5 in an app. I have an MXML class with a bunch of UI in it. I have been asked to add a switch that causes the positions of some of the different child components to change. The components use constraint-based layouts, so this is going to amount to modifying their left, right, top, and bottom styles. This only needs to happen once per object creation. In the docs: http://livedocs.adobe.com/flex/3/html/help.html?content=styles_08.html Some applications must call the setStyle() method during the application or object instantiation. If this is the case, call the setStyle() method early in the instantiation phase. Early in the instantiation phase means setting styles from the component or application's preinitialize event, instead of the creationComplete or other event. By setting the styles as early as possible during initialization, you avoid unnecessary style notification and lookup. For more information about the component startup life cycle, see Improving Startup Performance. Putting these style sets in preinitialize is impossible because the children have not been setup and are null. At this point, I am making the calls in the handler for the initialize event. Is there an acceptable way to do this without having to create two versions of the class subclass the children?

RE: [flexcoders] help with a repeater
BTW, you should consider moving to Spark components and using a Spark DataGroup
rather than a Repeater. A DataGroup is more efficient when you have many data
items that need to be rendered because it only creates item renderers for the
data items that are visible. Repeater always creates all of them.

you can only know what the type of the value is ( BitmapData ) the type of the

RE: [flexcoders] init, creationcomplete and other events
From the ASDoc for these events: preinitialize: Dispatched at the beginning of the component initialization sequence. The component is in a very raw state when this event is dispatched. Many components, such as the Button control, create internal child components to implement functionality; for example, the Button control creates an internal UITextField component to represent its label text. When Flex dispatches the preinitialize event, the children, including the internal children, of a component have not yet been created. initialize: Dispatched when the component has finished its construction and has all initialization properties set. After the initialization phase, properties are processed, the component is measured, laid out, and drawn, after which the creationComplete event is dispatched. creationComplete: Dispatched when the component has finished its construction, property processing, measuring, layout, and drawing. At this point, depending on its visible property, the component is not visible even though it has been drawn. applicationComplete: Dispatched after the Application has been initialized, processed by the LayoutManager, and attached to the display list.

Subject: [flexcoders] textInput - Flex 4 vs. Flex 3
In Flex 3 you could set an initial value for a textInput field like so:
mx:TextInput id=textinput1
text={data.name}
editable=true

I haven't been able to do this in Flex 4 -- does anyone know a way to achieve
the same result?

RE: [flexcoders] Updating Static vars

If you make them static getters rather than static vars, they can return
something different every time you access them.

Subject: [flexcoders] Updating Static vars
Hello I've got a situation as follows
1. I have a class called MessageStrings.as that I use for storing static consts
and variables used throughout my project.
2. Recently, we started an affiliate program where I need to make modifications
to the MessageStrings to change company names, email addresses, etc depending
on which affiliate is loading the page (from url string)
3. Instead of copying a bunch of static vars like
public static var CONTACT_US:String = Hello, contact us by phone at: +PHONE;
public static var CONTACT_US_AFFILIATE:String = Hello, contact us by phone at:
+PHONE_AFFILIATE;
and switching all the references I have to MessageStrings for affiliate info I
would like to do
public static var CONTACT_US:String = Hello, contact us by phone at:
+getPhone();
and have a new variable (static var) called THE_AFFILIATE that gets set by a
static function and getPhone returns a static var depending on what
THE_AFFILIATE is set to.
where getPhone is something like this
public static function getPhone():String {
var retPhone:String = ;
switch (THE_AFFILIATE) {
case MY_BUSINESS:
retPhone = SUPPORT_PHONE;
break;
case AFFILIATE:
retPhone = SUPPORT_PHONE_AFFILIATE;
break;
}
return retPhone;
}
So, this almost works, problem is that the class (MessageStrings) sets all the
variables intially and then when I set the Affiliate info later, the static
vars are not updated, and therefore do not reflect the text I want to see.
Is is possible to update all the variables that are affected by a change to the
affiliate? Kinda like calling the constructor again, but that won't work cause
it resets my affiliate variable?
RE: [flexcoders] Implement question
If class C implements interface I, and object o is an instance of C, then the expressions o is C and o is I are true. This means that o can be passed to any code that expects either a C or an I; it satisfies both types at once! Generally you use the interface I to express the public contract of what the object can do, and the class C to implement the details. Implementing multiple interfaces makes this even cooler. You might have a library of code that deals with carbon emissions and works with ICarbonEmitters, and a library that works with IVehicles and does transportation scheduling algorithms. If you had a Car class that implemented both ICarbonEmitter and IVehicle, then either library could work with an instance of Car.

You could also use an array specifying the last age in each group - [ 2, 5, 8,
12, 15, 18 ] - and iterate over it until you find the first one where the age
is = the array entry. This would involve less code, but it would probably
execute slightly slower.
Finally, if the age groups were more sensible so that each one contained 3
ages, then you could just do something like int(age/3) + 1.

RE: [flexcoders] Handler functions convention
if you subscribe to the event using ActionScript,
not the mxml handler sugar, then you'll always get the event.
An MXML event attribute like click=trace(event.target) just autogenerates an
event handler that looks like
function clickHandler(event:MouseEvent):void
{
trace(event.target);
}
The attribute value is code that becomes the body of the handler.

I'd say it's up to you, but if you subscribe to the event using ActionScript,
not the mxml handler sugar, then you'll always get the event.
I have to pass a null in case it isn't triggered by the event, which seems
pretty cumbersome.
Perhaps you could use defaults in the handler, something like
login_clickHandler(event:MouseEvent = null)

This step is necessary if you are writing attributes like

But I don't think it is necessary if you use the @Resource() compiler directive:
label=@Resource(bundle='MyApp', key='someResource')
However, unlike the databinding expression, the @Resource directive doesn't
re-evaluate when the localeChain changes.

RE: [flexcoders] From your own experience how long does it take to learn AS3?
If you've never programmed before, I wouldn't expect you to be able to do much on your own after only 4 weeks. First, you need to make sure you understand basics like what is a variable, what is a function, what is a getter/setter, how to use various operators, how to write conditional and looping statements, what is a class, what is an instance, etc. There are a lot of fundamental programming concepts to understand before even getting to Flash Player and Flex Framework concepts like Events, Styles, and DataGrids. For example, let's start with something simple Do you understand how to write a function that adds up the first n integers, where n is an integer that you pass as an argument (and how to call it)? Just that involves functions, arguments, return values, local variables, and a for-loop. Do you understand how to use the debugger to watch it execute line by line, set breakpoints, inspect the loop counter and the sum, etc.? You're likely to succeed if you take baby steps and have patience. And ask questions when you get stuck!

RE: [flexcoders] Detecting Events in Flex
addEventListener() requires you to specify what kind of event you're listening for. However, any event dispatched by a UIComponent can be intercepted because UIComponent overrides dispatchEvent() to pass the event to an dispatchEventHook function that you can set. The static var for this hook function is mx_internal and therefore undocumented and subject to change or removal without warning.

RE: [flexcoders] Re: Pointers
I did not see a functional similarity to a pointer in actionscript or did I

All object references in ActionScript are similar to pointers in that they are
not the object itself, but references to it. For example, when you declare
var textInput1:TextInput = new TextInput();
var textInput2:TextInput = textInput2;
you haven't created two TextInput instances; you have made two variables refer
to (point to) the same TextInput instance.

Interesting but not quite the design issue I have in mind.
See http://www.danielpride.com/Vehicles3/Vehicles3.html
(Its still a little crude, basically playing with the tech.
Clicking on a row fills in a series of text boxes.
if you edit a box, I want to shift the state just like it does now
when you click the new button at the top, except now it will go to an edit
state.
The idea is you can examine a large data record by selecting it from a row of
important fields, then edit if you like or just look.
Its easy enough to compare the values field by field
but in my old language I would have written a very small
function with two pointers (new and old)
and then just called the same function in each
focus out, passing in the two pointers to the current
field of the focus event.
This has got to be childs play I would think
but newbie status prevents it from popping out of my head I guess.

RE: [flexcoders] Testing my understanding of Flex
Metadata is used to do a variety of things. Generally it affects how the ActionScript or MXML compilers work. For example, [Embed] metadata tells the ActionScript compiler to embed an asset such as a JPG. [ResourceBundle] metadata tells the ActionScript compiler to link a ResourceBundle subclass with localized strings. [Event] and [Style] metadata tell the MXML compiler what to do when it encounters attributes like click=... or fontSize= In general, metadata affects the SWF-or-SWC-compilation process. But I wouldn't describe it as being there for Flex Builder only because you can compile without using Flex Builder, such as with the mxmlc Ant task or the mxmlc command line tool. You're correct that if you don't use MXML then [Event] and [Style] metadata is irrelevant. But other metadata like [Embed], [ResourceBundle], and [AccessibilityImplementation] is.

It seems to me, that the events, effects, styles, etc become available in pure AS3 by simply importing the proper classes and using the appropriate methods. Is this the correct interpretation of the code, or am I missing something?
RE: [flexcoders] Question about flex source
Aaron is correct. The AS/MXML compiler ignores comments, and the @ in @eventType has nothing to do with an XML attribute (although this is what it would indicate if it were in AS code rather than in a comment). However, the ASDoc generator pays attention to all comments that start with /**, and does special processing on attributes like @eventType, @param, and @result inside these comments. We adopted this convention from how JavaDoc works.

RE: [flexcoders] mx.controls.Text
is there anyway to find the number of textRows in a TEXT. It sounds like you want the numLines of the TextField inside the Text control. I can't seem to get my text to measure properly You may be having timing issues. For example, if you ask for the width and height immediately after setting the text, they won't be correct because the LayoutManager hasn't run a validation pass (i.e., commitProperties(), measure(), and updateDisplayList() haven't executed). But if you wait for an updateComplete event, they will be correct.

RE: [flexcoders] am a newbie , can somebody explains to me this simple For loop statement?
Are you asking for an explanation of the for-loop? The comment above it
explains what it does. The general form is
for (a; b; c)
{
d;
...
}
and it is basically equivalent to the following while-loop:
a;
while (b)
{
d;
...
c;
}
The 'a' part is typically an assignment statement to initialize a loop
variable like an integer i that starts out at 0 and increments to 1, 2, 3, etc.
The 'b' part is typically a conditional expression evaluating to true or false,
telling the loop whether to keep going or not. (Have I reached the end of the
collection yet?)
The 'c' part is typically an expression like i++ to increment the loop variable
for the next pass.

Subject: [flexcoders] Inline functions and Anonymous
Hi everyone, I have a quick question. Is there any performance gain when using
an inline or anonymous function in flex??
For example let's say you have:
private foo function():void{
var btn:Button = new Button();
var str:String = Hello Guys;
btn.addEventListener(MouseEvent.CLICK, function(event:MouseEvent):void{
Alert.show(str); } );
}
So I realize the advantage to using inline functions is that you can use local
variables that are defined in the scope for example the str variable. But what
happens when you have the extreme case like this:
private var run:String = one;
private function main():void{
function boo()void{
Alert.show(boo hoo);
}
foo(boo);
}
private function foo function(bar:Function):void{
var str:String = Hello;
function fnc1a():void{
function fnc1a():void{
Alert.show(str+ function 1 A!);
bar();
}
function fnc1b():void{
bar();
Alert.show(str+ function 1 B!);
}
runFuncs(fnc1a, fnc1b);
}
function fnc2():void{
Alert.show(WOW This can be confusing!);
}
if(run == one){
fnc1();
}
else if(run == two){
fnc2();
}
else{
bar();
}
}
private runFuncs(a:Function, b:Function):void{
a();
b();
}
nice eh? _ So what are the disadvantages?? My main concern here is memory
leaks and performance. I was looking at the profiler and I think the garbage
collector may not be cleaning up all the unused functions.
Please help :D

RE: [flexcoders] Re: When does 0.2 and 0.1 not equal 0.3?
Unfortuantely, floating-point arithmetic in most CPUs and computer languages today is based on binary fractions (1/2, 1/4, 1/8, 1/16, ...) not decimal fractions (1/10, 1/100, 1/1000, 1/1000,...). There is no ActionScript Number (or C++ double) that is EXACTLY equal to 0.1, 0.2, or 0.3 because doing so would require an infinite number of binary fractional bits. (Some fractions such as 0.5 can be exactly represented because they only need a few binary fractional bits.)

Hello,
Does anyone know if it's possible to check if an object has a given property?
objADGLD is of type AdvancedDataGridListData which always contains a property
called .item
Looking at the debugger, objADGLD.item's Declared Type can either be an Object
or XML in different situations.
When it is an Object I want test if objADGLD.item.GroupLabel exists.
In JavaScript, I could've done this...
if ((objADGLD.item) (objADGLD.item.GroupLabel))
{ // do something... }
... but it doesn't seem to be working for me in Flex.
Are there any good object inspection routines to help with this?
Thanks,
Nick
RE: [flexcoders] how can I parse this Srting in Flex
I would use String's split() method to split your string on the | character into the Array [ Label1, url1, label2Explorer, url2, Label3, url3 ]. Then you can use a for-loop to walk through this 6-element array and create a new 3-element array by combinding elements 0/1, 2/3, and 4/5. But if the six elements in the string are grouped into three pairs of two, then it would obviously be less work if it were stored as Label1|url1||label2Explorer|url2||label3|url3 You could then simply split it on ||.

RE: [flexcoders] cast/convert to a child class?
ArrayCollection does not have any idea what type of elements you put into it. You can have an ArrayCollection full of Dog instances, or an ArrayCollection full of Cat instances, or an ArrayCollection full of Cats and Dogs (i.e., Pets). But all are just ArrayCollections and no casting is required. You're probably thinking of Vector.Pet vs Vector.Dog. There are indeed different types, and one cannot be cast to the other.

RE: [flexcoders] double underline on text
Neither TextField nor TLF support double-underlining, so you'll have to draw it yourself.

RE: [flexcoders] 2 strange issues for begginer in action script ref
Issue 1: It looks like you want to create a Flex button. If so, you want
mx.controls.Button, not mx.core.ButtonAsset. But you can't take a Flex Button
and have it work inside a plain old Sprite, which is what a pure
ActionScript-based app is. Flex is an application framework, and Flex controls
expect to be inside of Flex containers. So you have to start by creating, in
MXML, an mx:Application or an s:Application. Once you have that, you can do
everything else in AS rather than MXML if you really don't like MXML. But it's
a lot easier to just write mx:Button.
Issue 2: Again, it looks like your problem is that you're expecting Flex
controls to work inside of pure ActionScript apps.

Hello... I am new to action script and I am (pretty) confused... so any help is
valuable!!!
--- issue 1
-
I have the follow code... and I get blank page... nothing is appeared on the
stage at all!!! For god's sake, what is wrong?
package
{
import flash.display.Sprite;
import mx.core.ButtonAsset;
public class ASProject2 extends Sprite
{
public function ASProject2()
{
var mb: ButtonAsset = new ButtonAsset();
mb.x=100; mb.y=100; mb.width=200;
addChild(mb);
}
}
}
--- issue 2
-
Which button is the more simple button to use?
I found the spark components button is the component that Flash Builder uses if
you write in mxml language. So I add the folder to my project's libraries
paths, in precise I added as SWC folder the follow folder:
c:\Program Files\Adobe\Flash Builder
Beta\sdks\4.0.0\frameworks\projects\flex4\src\spark\components\
Here is the (very simple) code (with compiler's errors):
package
{
import flash.display.Sprite;
import spark.components.Button; // - compile time error: 1172: Definition
spark.components:Button could not be found.
public class ASProjectInFB4 extends Sprite
{
public function ASProjectInFB4()
{
var ab : Button = new Button(); // - compile time error: 1046: Type was
not found or was not a compile-time constant: Button.
ab.x=10;
ab.y=10;
ab.width=200;
ab.height=100;
ab.enabled=true;
addChild(ab);
}
}
}
The problem (as you see) are the two compiler errors. Now... if get the cursor
on Button text in my code and I press the F3 the Flash Builder transfers me
to the declaration of Button class in the proper Button.as file! So I suppose
that my definition in my preceding code is correct. If I remove the the SWC
folder from the libraries of my project, the F3 buttons doesn't transfer me
anywhere, so the SWC folder definition is working too...
What is wrong?

RE: [flexcoders] Resources for compiling with asc.jar
I don't really know much about using asc directly... I've never had any reason to use it. Regardless of whether I'm compiling MXML or AS, I use mxmlc. I suppose asc might be faster for special uses, but it is less flexible; it doesn't understand MXML, and I'm pretty sure that it requires all of your AS to be in a single file, not multiple files that import each other.

createToolTip().

RE: [flexcoders] Hover Event over Text
With TextField-based text in MX components, I don't think this is easy. You'd probably have to use mouseMove to track the mouse within a TextField and low-level TextFIeld APIs to discover what range of characters the mouse is over.

Are there any resources that describe the internals of the Flash player? Is there a spec like there is for the Java runtime? Unfortunately, no.

RE: [flexcoders] Race conditions when event handlers triggered from different targets
Yes, that is what Alex is saying. Handler B will not begin before handler A finishes. Event handlers don't get paused. Furthermore, when you (or the Player) calls dispatchEvent(), all the event handlers listening for that event execute before dispatchEvent() returns.

Just to be clear, are you saying that once event handler A' begins executing, another event handler B' will not begin executing until A' finishes? Even in a single-threaded environment, not knowing how the flash player works, it is possible that the player could decide to pause an executing event handler to allow another to progress. That would create the scenario I am describing.

Actually, no. It would interpret it as null if it were enclosed in curly braces
like this:
var xml:XML = outerinner{null}/inner/outer;
And even then, null might be converted to its String value, null, as the
content of the element. I'd have to try it to know for sure.
In the example I gave, the content of the element is a String consisting of the
letters n, u, l and l, in that order.
In any case, the xmlList variable would reference a non-null XMLList object.
That's easily proven by dereferencing it:
trace(The length is + xmlList.length());
That would output The length is 1.

All e4x expressions return an XMLList. It can be empty but is never a null.

Like Tracy , I thought it would return false, for the same reason -- that
innernull /inner would be interpreted as a string. Was surprised when I ran

null as a special case.

RE: [flexcoders] Re: How to make variables persist across application
The simplest way to use custom events is to use the mx.events.DynamicEvent
class.
When the application creates the LoginPopup component, have it listen for
login events like this:
var loginPopup:LoginPopup = new LoginPopup();
loginPopup.addEventListener(login, loginHandler);
PopUpManager.showPopup(loginPopup);
Have your LoginPopup class dispatch a login event when it closes:
var loginEvent:DynamicEvent = new DynamicEvent(login);
loginEvent.username = usernameTextInput.text;
loginEvent.passwrod = passwordTextInput.text;
dispatchEvent(loginEvent);
Have you application handle the login event like this:
private function loginHandler(event:DynamicEvent):void
{
// do something with event.username and event.password
}
If you want to be more formal and type-safe, you would declare an AS subclass
of Event instead of using DynamicEvent, but that's another lesson.

Is there a way to have the variables I set in a pop-up window (think
login), persist and be accessible even when that pop-up is closed?
For example, I have an application that uses a pop-up login window to
control access to the application. The user supplies userid, password and
role. When the user is authenticated, the pop-up closes and a viewstack is
displayed based on the results of the role selected in the pop-up.
All that works just fine. Now, I want to display the userid in the
components within the viewstack. For example I want to display a welcome
message based on the userid.
I cant seem to figure out how to do this. Any help would be appreciated.

Write a data storage class like this:

public class LoginInfo
{
public static var username:String;
public static var password:String;
}
In your LoginPopup component, import LoginInfo and do something like like
LoginInfo.username = usernameTextInput.text;
when the popup is closed.
Static vars simply live in the class itself, not in an instance of the class.
You can reference them from anywhere.

Subject: [flexcoders] How to make variables persist across application
Is there a way to have the variables I set in a pop-up window (think login),
persist and be accessible even when that pop-up is closed?
For example, I have an application that uses a pop-up login window to control
access to the application. The user supplies userid, password and role. When
the user is authenticated, the pop-up closes and a viewstack is displayed
based on the results of the role selected in the pop-up.
All that works just fine. Now, I want to display the userid in the components
within the viewstack. For example I want to display a welcome message based
on the userid.
I cant seem to figure out how to do this. Any help would be appreciated.

RE: [flexcoders] how to find a dynamic object in a function?
One way is to use .parent, because the RadioButton is a child of VBox so that
VBox is its parent.
Another way is to use the fact that if you give the VBox tag an id like
id=vb, then you can refer to the ith VBox as vb[i]. And you can determine
what value of i to use by using the .instanceIndex property of the RadioButton
that you're processing.

Subject: [flexcoders] how to find a dynamic object in a function?
Hi All,
This might be a simple question, but I have no clue:
For example, I use mx:Repeater to create a list of radioButton, each inside
a vBox, so the code is like this:
mx:RadioButtonGroup id=myRG itemClick=selectMyRadio(event)/
mx:Repeater id=myRP dataProvider={myList}
mx:VBox name={myRP.currentItem.value}VB
mx:RadioButton value={myRP.currentItem.value}
label={myRP.currentItem.label} groupName=myRG /
/mx:VBox
/mx:Repeater
what i want to do is, when user selects one radio button, i want to use its
VBox to do something, how to i get the vBoxobject in the function?
private function selectMyRadio(event:Event):void
{
// so i can get the selected radio button value:
event.currentTarget.selectedValue
// now how to get the vbox object from the application by using that
value? the vBox name is: value+VB
}
thanks!
C

RE: [flexcoders] Instantiation of State Objects
In the Flex 3 states model, if you start in state A, go to state B which creates and adds a child, and return to state A, the child is removed from the display list but kept around. When you return to state B, it doesn't have to be recreated and can just be re-added. In the Flex 4 states model, the default behavior is the same, but you can use destructon policies to say that the child should not only be removed from the display list but also freed for garbage collection.

Basically, I want to know if I swap between states, are the objects defined by AddChild new instances every time I enter that state.

RE: [flexcoders] Re: Question about a flex component
UIComponents have a visible:Boolean property which you can set to true or false. You can tell whether a Container is scrollable by checking whether its maxHorizontalScrollPosition is greater than 0.

RE: [flexcoders] Re: How to customize ThousandSeparator to display price in INR format
That's correct. Improved locale-aware formatting capabilities that will handle this case are being built for a future version of the Flash Player. But the current Flex formatters only know how to insert a thousandsSeparator every three digits.

Scrolling components can scroll through thousands of items quickly. Suppose there are 100 items and you can only see 10 at a time. So first you see 0-9. When you click the icon you see 10-19. When you click it again you'd see 20-29. So you'd need another icon (previous page instead of next page) to go back to 10-19 and then 0-9.
