Re: [Flashcoders] How to add a DisplayObject into a container without using addChild() method.
I highly suggest reading Practices of an Agile Developer http://www.pragprog.com/titles/pad/practices-of-an-agile-developer Use KISS. Stay DRY. Code less. Code smart (code S-Mart). Use smart shortcuts when they're available to you. Implicit boolean coercion is one such shortcut, among many others. We need to get things done. We don't have the luxury that academia has to argue about theory for months and years. You've spent as much time arguing about this as people typically spend typing out Boolean expressions in the first place. Honestly, if you're finding an extra ten or so characters a burden, you may have other problems that are unrelated to the value of using implicit Boolean evaluation. This has nothing to do with getting things done or arguing about theory. But anyway, arguably, keeping it simple doesn't mean keeping it brief. An explicit Boolean expression is simpler to read and understand than an implicit Boolean evaluation. Not all languages support implicit Boolean evaluation, so I have to remember one set of rules for some environments and a different set for others - not simple. Again, I'm not saying there's anything wrong with implicit Boolean evaluation, I just think it's a mistake to believe it's inherently superior to an explicit, slightly longer Boolean expression, to the point of telling people they should replace one with another. And as much as I like Ash, I'm not sure I want to take coding advice from the guy who couldn't remember klaatu barada nikto - maybe he was too enamored of shortcuts?

Ugh, then you go and use an if statement without brackets, and on the same
line to boot! I for one, would not want to maintain your code.
This is in jest of course. I am not going to say doing things shorthand is
wrong, but there are some very valid merits to not doing the shorthand
methods.

Steven,
Maybe its just me but...
Just doing a Boolean check on DisplayObjects always put my scripts in high
risk of runtime errors.
Especially in the case of cleanup operations.
Sometimes I might have a function that attempts removing a DisplayObject
that has not been added to the stage or has already been removed.
So I check if the stage property is null for almost all cases now.
var myDO:Sprite=new Sprite();
try {
//if (myDO) { //Creates runtime error
if (myDO myDO.stage != null) {
myDO.parent.removeChild(myDO);
} } catch (e:Error) {
trace(e.message);

Re: [Flashcoders] How to add a DisplayObject into a container without using addChild() method.
Writing readable code writing less code.
That is what it comes down to. Most coders can understand both of the
following:
if(myObj){;}
and
if(myObj != null){;}
I would opt for the latter method always, as otherwise you are relying on
renderer specific logic to handle the conversion, as opposed to explicit
conversion.
I have actually spent an hr trying to debug an IE specific JS error, only to
find that even though implicit type conversion was working in other
browsers, it was throwing an error in a specific version of IE.
By your argument of less code more code, this:
public function outputList():*{;}
would be better than
public function outputList():Array{;}
and AS2 would be better than AS3 on the whole basis that you didn't have to
typecast anything.
Just because a certain environment can convert types for you, doesn't mean
that you shouldn't typecast or not hint as to their object type in your
code.
Personally, I can type faster than I can think in code. I type really fast,
and I think code really fast, and typing out the extra 10 characters doesn't
hinder my productivity, it probably enhances it.
If you want to take the implicit convesion route, by all means I am not
going to stop you or object. However, I do and will always believe that it
is better for other people reading/working on your code that you do spell it
all out, use line breaks when it makes sense, and typecast all your
variables.
I think Dave's point was that you seemed rather authoritative, and this is
really a subjective matter.

That is what it comes down to. Most coders can understand both of the
following:
if(myObj){;}
and
if(myObj != null){;}
I would opt for the latter method always, as otherwise you are relying on
renderer specific logic to handle the conversion, as opposed to explicit
conversion.
I have actually spent an hr trying to debug an IE specific JS error, only to
find that even though implicit type conversion was working in other
browsers, it was throwing an error in a specific version of IE.
By your argument of less code more code, this:
public function outputList():*{;}
would be better than
public function outputList():Array{;}
and AS2 would be better than AS3 on the whole basis that you didn't have to
typecast anything.
Just because a certain environment can convert types for you, doesn't mean
that you shouldn't typecast or not hint as to their object type in your
code.
Personally, I can type faster than I can think in code. I type really fast,
and I think code really fast, and typing out the extra 10 characters doesn't
hinder my productivity, it probably enhances it.
If you want to take the implicit convesion route, by all means I am not
going to stop you or object. However, I do and will always believe that it
is better for other people reading/working on your code that you do spell it
all out, use line breaks when it makes sense, and typecast all your
variables.
I think Dave's point was that you seemed rather authoritative, and this is
really a subjective matter.

Re: [Flashcoders] How to add a DisplayObject into a container without using addChild() method.
Hello :)
Use an argument in the constructor of you class to passed-in the parent
reference of your display
public function MyDisplay( target:DisplayObjectContainer = null )
{
if ( target != null )
{
target.addChild( this ) ;
}
}
PS : your code isn't valid in the constructor of a DisplayObject the stage
and parent properties are null ! Only in the main class of your
application this two attributes are not null.

Hi guys,
I am curious about if am able to add the DisplayObject into a container
without using addChild() method, this class is very simple...
1. package
2. {
3. import flash.display.Sprite;
4. import flash.events.Event;
5.
6. public class MyClass extends Sprite
7. {
8.
9. public function MyClass ()
10. {
11. //addEventListener( Event.ADDED_TO_STAGE , addedHandler );
12. parent.addChild(this);
13. }
14. /*
15. private function addedHandler( e:Event ):void
16. {
17. removeEventListener( Event.ADDED_TO_STAGE , addedHandler );
18.
19. parent.addChild(this); // how could I retrieve the instance name of
this?
20. }
21. */
22. }
23. }
I'd like to do something like
var do:MyClass = new MyClass();
//addChild(do) // added it into displayobject without using this method
here
Is that possible? any suggestions are welcome :)

Re: [Flashcoders] How to add a DisplayObject into a container without using addChild() method.
I don't understand why you would not want to write a single line of code in the
class where it would provide the most clarity, and instead write MORE code in
another class obscuring the behavior that is going on. In other words, you're
writing more code to write the same code. You're going to write addChild either
way, why make it more complicated than it needs to be?

Re: [Flashcoders] How to add a DisplayObject into a container without using addChild() method.
if (Boolean) Everything inside an if statement is automatically coerced into a Boolean. Either it is or it isn't. It's not more clear to write != null because an if statement cannot possibly be anything other than true or false. In this case, null or not null. Writing it out is redundant (and more code).

Re: [Flashcoders] How to add a DisplayObject into a container without using addChild() method.
Steven,
Maybe its just me but...
Just doing a Boolean check on DisplayObjects always put my scripts in
high risk of runtime errors.
Especially in the case of cleanup operations.
Sometimes I might have a function that attempts removing a DisplayObject
that has not been added to the stage or has already been removed.
So I check if the stage property is null for almost all cases now.
var myDO:Sprite=new Sprite();
try {
//if (myDO) { //Creates runtime error
if (myDO myDO.stage != null) {
myDO.parent.removeChild(myDO);
}
} catch (e:Error) {
trace(e.message);

DisplayObject that has not been added to the stage or has already
been removed.
So I check if the stage property is null for almost all cases now.
var myDO:Sprite=new Sprite();
try {
//if (myDO) { //Creates runtime error
if (myDO myDO.stage != null) {
myDO.parent.removeChild(myDO);
} } catch (e:Error) {
trace(e.message);
}
