Here is the example:
1. create an new movieclip and put a rectangle in as background
2. on top (or higher layer) put a dynamic textfield, give it an instance
name of tf
3. give the movieclip in the library a linkage MyButton
4. paste this code in the first and only frame on the Main timeline!:
//BEGIN CODE
//create array for buttonlabels
var arrButtonsLabels:Array = [One, Two, Three, Four, Five, Six,
Seven];
var arrButtons = [];
var amount:int = arrButtonsLabels.length;
//Using one loop to do it all
for (var i=0; iamount; i++) {

b.tf.text = arrButtonsLabels[i];
//position buttons
b.x = Math.round(stage.stageWidth-(amount*b.width))/2 + i* b.width;

Re: [Flashcoders] Adding a property to an AS3-component
The array is just handling objects, so you lose the protection that having known classes gives you. There are occassions when having dynamic classes is essential, but they must be rare. I think too many developers just try and emulate the bad habits of AS1 and AS2 to get around learning the good habits of AS3 ( explicit classes, inheritance, etc.). Dynamically adding attributes like this makes you open to runtime failure, something that extending classes helps to protect you from. I know - I get tempted by the dark side myself..

Re: [Flashcoders] Adding a property to an AS3-component
Ofcourse that works, you're using plain MovieClips, which are dynamic.
This has nothing to do with the use of an Array.
The original question was how to do that with Button components, which you
can't since they're not dynamic.
As already mentioned, extend the required class and add the property/properties
you need.
But I thought the questioner was not in to that, so maybe a bad habit is a
better solution, then none.
Afraid I disagree.. especially when passing them on to others it becomes super
bad.

RE: [Flashcoders] Adding a property to an AS3-component
You can edit the components class. But I always put my objects in arrays. So you can do this: var arrButtons:Array = []; var button:Button = new Button(); arrButtons.push(button); arrButtons[0].old_item = 42; addChild(button); HTH Cor ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
Re: [Flashcoders] Adding a property to an AS3-component
is it actually possible to add a new property to an AS3-component, like button? In AS3, classes will only allow this if they're dynamic classes, and most classes aren't dynamic. You could, however, write a new class to extend Button.
