Re: [Flashcoders] Weak eventListener Problem
I make destroy methods, avoid using extra references to listeners and am compulsive about cleaning them up, still some continue to execute imperviously. I hate when this happens cause its unpredictable and unexplainable. All I know is the Real garbage collectors are sometimes late picking up my garbage after I put it outside for them. -- Keith H -- www.keith-hair.net Steven Sacks wrote: No, it's not true. You're misunderstanding how weak listeners work, how anonymous functions work (you shouldn't use those anyway), and you're also misunderstanding how the garbage collector works. Whenever you addEventListener, immediately write a function that removes the event listener (such as a destroy method). If you get into this habit, you will never forget to do it and you'll never have this issue ever again. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

Re: [Flashcoders] Weird htmlText line break behavior

I'm encountering an odd problem in as3/fp9-10 when dealing with embedded
fonts, condensed whitespace, style sheet objects and br / tags. I wanted
to see if you guys have heard of it or can verify it as a bug.
I have a textfield set up as such. The intent is to remove all p tag
indents and get fully left justified text with paragraphs having larger
leading than individual lines :
var myTF:TextField = new TextField();
myTF.autoSize = TextFieldAutoSize.LEFT;
myTF.embedFonts = true;
myTF.condenseWhite = true;
myTF.antiAliasType = AntiAliasType.ADVANCED;
myTF.multiline = true;
myTF.wordwrap = true;
myTF.styleSheet = myStyleSheet;
The stylesheet is an imported .css file and below is the html imported from
an .xml file and protected by a CDATA tag:
h2About Us/h2br /
p class=normalstrongLorem/strong ipsum dolor sit amet,
consectetur/pbr /
p class=normalLorem ipsum dolor sit amet, consectetur./pbr /
p class=normalLorem ipsum dolor sit amet, consectetur./pbr /
p class=normalLorem ipsum dolor sit amet, consectetur./p
The result is fully left justified text but the br / tags are ignored.
Each paragraph does start on a new line but directly below the the previous.
I decided to try a version of the css clear break trick used in xhtml which
produced the results I wanted but for no discernible reason.
I created this style in the .css file,
.lineBreak {
leading: 20;
}
and altered ONLY the first br / tag to this p class=lineBreak /
The weird thing is that not only did the first paragraph get the correct
amount of space, they all did. For some reason, an empty styled p / tag
caused the following br / tags to be recognized.
Thoughts?

Re: [Flashcoders] How to add a DisplayObject into a container without using addChild() method.

Had he checked against 0, at least this method could have been used as a
generic replacement for the obscure and unreadable implicit boolean
coercion...
He also had the chutzpah to put this method in our core library, in a class
conveniently named VarUtils, so the whole team could benefit from it.
To add insult to injury, he had a very personal take on hungarian notation
and code formatting as well. Not to mention he was also in the tabs should
be 8 spaces here, there and everywhere, and if you and the rest of the world
use 4 spaces, rest asured I will reformat any such piece of crap as soon as
I get a chance to put my hands on it camp.
Nevertheless, he was a cool guy.

some great optimalistations can be found here:

for ex.
class Truth
{
boolean isTrue ( boolean assertion )
{
if ( assertion != false )
{
return assertion;
}
else
{
return assertion;
}
}
}
...
var doIt:Boolean;
var trutherizer:Truth = new Truth();
if ( trutherizer.isTrue( s.equals( t ) ) )
{
doIt = true;
}
else
{
doIt = false;
}
// hint: all the above accomplishes is:
doIt = (s==t);

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);
}

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?
Always follow the KISS principle.
BTW, Ekameleon, you should use
if (target)
Instead of
if (target != null)

Re: [Flashcoders] How to add a DisplayObject into a container without using addChild() method.
Thanks.
That is a better way to write the check. (Clever! you escaped from using
null once again LOL)
BTW I just put the try/catch there to demonstrate error.

Re: [Flashcoders] array.indexOf problem
trace (buttonsArray.indexOf(e.target.name));
Looking at the aboveyour buttonsArray is an Array containing
Objects.
And you are using the indexOf method looking for a String.
Take off the .name property and you should see a difference.

Hi fellows,
Cannot solve this problem:
function buttonClicked(e:Event):void {
trace (buttonsArray.indexOf(e.target.name));
It always traces -1. This code should trace the index of the Array
element right? for ex: 0, 1, 2 or 3.
If i do this, it will trace the correct name of the element.
function buttonClicked(e:Event):void {
trace (e.target.name);
If I do this, it will trace the name of the second element:
function buttonClicked(e:Event):void {
trace (buttonsArray[1].name);
Why indexOf doesn´t work properly?
Thanks a lot!
