ActionScript 3.0 :: Extending SimpleButton So Can Access Its Child Objects?
Jul 3, 2009
i have a simple navigation system with three buttons, each button have a text field in it. On mouse over they change color to blue. I can achieve all these without a single line of code. I simply make a button of my text field in flash, and change the color of the text in the timeline.
My problem occurs when i want to make the color to stay blue when i click on the button. Apparently you can't access the child within a button, in my case a dynamic text field. I've googled this problem and they all say that you should use a MC instead of a button. Thats exactly what i have done so far. But i'm getting tired of writing a bunch of eventlisteners and put an extra layer with an invisible button in my button mc so i can get the hand cursor (because the .buttonMode = true and useHandCursor doesn't work when there is text field inside the mc). Any way, shouldn't there be a more elegant way to solve this problem?
I've been trying to build a new base class for my button that extends SimpleButton, and from there access the embedded child object, but the problem remains.
In this example i'm trying to simply change the text of the text field inside of my new MyButton instance. But i get the same old Error #1009: Cannot access a property or method of a null object reference.
package
{
import...
public class Mybutton extends SimpleButton

I need to have a button that contains a text box, and have the text change. First, is there a way to access a text box directly in a SimpleButton? While I know this doesn't work, it would look something like
Code:
btn.upState.textField.text="Text"
Second, since I could not get that to work, I made a movie clip, put the button i made in it, and simply put the text box over the button. The problem this creates is that when the mouse is hovering over just the button it is in the over state. When the button moves over the text box it goes back to the up state. Why it does this and if it is possible for the button to still be in its over state when the mouse is over an object that is on top of the button itself?

I created a button (button symbol), inside this button symbol there is a vector shape which will change colours in mouse over and a dynamic text field. i want to use this button symbol in more than one locations in my stage. so i need to change the label of these instances (by changing dynamic text ). but i can't access the dynamic text in as3 using following code,
btnsample.txtbtnlabel.text = "button label"
this code is working fine for a movie clip symbol but not for a button symbol.

I'm not much of a web/flash designer, but I need to showcase my print work online - so I apologize foremost for the noob-ness. I tried to search for this, but came up empty. I am loading external swf movies via loadMovie, into my "base" (main) flash file which will essentially be my website. Everything is loading fine.
I have an swf file that when I load (with loadMovie) objects are extending beyond the set stage size of the swf and onto the "main" flash file. This only occurs with objects that are "off" of the stage. For example, I have a background which is larger than the set stage size, when I load the swf, the movie loads up, but it allows the background to extend beyond the stage size. Is there a way to "crop" the flash file? All I need to do is load a movie without "hidden" objects appearing. (I also have checked that in publishing preferences.)

This is a problem that's best explained in code. I don't see how active_button.upState, which I know is a TextField (see trace statements), mysteriously turns into a DisplayObject when I try to access the textColor property. I've included the error messages below for reference. Also, why is it that when I have an object that I know is a SimpleButton (again, see traces) I need to cast it to SimpleButton in order to store it in a var? That doesn't make any sense to me.

Let's say I have a defined ClassA. ClassB extends ClassA and there's a Movie Clip instance on the stage linked to ClassB. How would ClassC access the properties and methods of ClassB without extending ClassB or creating a new instance of ClassB? The way I'm currently doing it is by referencing the stage instance linked to ClassB and then using the dot syntax to access ClassB instance variables, and this works only if the the accessed variables are public or internal, depending on what package ClassC is part of. I would like to know if there's a better, cleaner way to accomplish this.

I've seen some discussion on how to load a child swf using swfLoader and accessing it's variables but I am wondering if it is possible to do this without adding any code to the child swf.Either accessing public vars or listening for funciton calls would work fine

I'd really like to be able to make Flash's array access syntax 'wrap' over the array's bounds.
Lengthy explanation -
var array:Array = ['a','b','c','d','e','f'];
To keep things simple, the first index is 0, and its value is the first letter, 'a'. To get that value, we'd do this -
array[0]; // returns 'a'
As long as the index you're using to access the array is between 0 and array.length (6 in our example,) everything works fine - but if you use an index outside of those bounds, you're shut down.
array[-3];
array[9]; // both return 'undefined'
Sometimes that's a good thing - sometimes you expect that to happen, and you're fine with it. Other times, you find yourself wishing (or at least I find myself wishing) that it'd behave a bit more like this -
array[-3];
array[9]; // both return 'd'
(e.g. a photo gallery that jumps back to the beginning when you click 'next' on the last photo)There's a little chunk of code I use over and over for this sort of thing, but it's always to alter the index before passing it into the array:
var index = -3;
while(index < 0){index += array.length}
array[index % array.length]; // returns 'd'
... and that's fine, but what I really want to do is extend the Array object itself so that it'll automatically 'wrap' index values that go out of bounds.TL;DR - Is index-wrapping possible by extending Flash AS3's Array object?

I have a component with a public variable declared
[Bindable]
public var mnuSource:String;
When I extend this component, I can reference mnuSource (it compiles) but Runtime complains about the property not being accessible (error 1056).
How do you modify / declare component properties so they are actually available to other components?

I've been trying to create a custom mxml component that extends another custom mxml component (i.e.MyMXMLComponent -> BaseMXMLComponent -> Group). I've been reading that trying to add visual children to MyMXMLComponent caused error with Flex 3 but that's no longer the case with Flex 4.
What I want to know is whether this is a supported/fixed/documented feature of Flex 4? or just some undefined behavior in Flex 4 that may get changed with future updates?
if this is supported and documented feature, does anyone have link pointing to adobe document stating it as such?

I want to set the scaleX and scaleY of certain child objects within a movieclip, but there are tons of other elements inside of it. Here's what I have so far:
for (var i:uint = 0; i < outer_mc.numChildren; i++) {
trace(' | ' +i+'. name:' + timeline_mc.getChildAt(i).name);
}
This returns 60 child objects. The 50 I want to scale down have "_mc" appended to their instance name. I figure I should make a new array or variable and set the scale of those to whatever I want.

On stage I have 2 objects on stage that share the base-class of "ABaseClass". Each has a child object that shares the base-class of "AnotherBaseClass". They child objects do not share the same parent, and have unique Linkage identifiers of "Object2Design" and "Object1Design", so they should be able to share the same name on the display-list, right? But if these child objects share the same name I get the following error. How to allow child objects to share base-classes and names?
TypeError: Error #1034: Type Coercion failed: cannot convert Object2Design@256cfe81 to Object1Design.

in short, i have object A, a container. Within this is object B (a child object) which has some x and Y offset that I input.I need to know the offset of object B, because i want to place other objects at the same onscreen position as B, but on the same level of the heirarchy as object A My problem though, is that B's offset from A isn't changing when i would expect it to - when the parent object is scaled. I set B's x offset to 200 pixels, and no matter how much i scale up or down the parent object, B remains in the same visual position relative to it. And B's x property is still 200, regardless of parent scale.This information is not meaningful to me, because i know that B's actual offset position from A is more or less than 200 onscreen pixels. I need to be able to figure out exactly what it actually is.

I'm moving two objects accross the stage at different rates using the same function:
Code:
function moveClip(clip,speed){
clip.addEventListener(Event.ENTER_FRAME,moveIt);
function moveIt(event:Event) {

In AS2 I'd just use dot notation as above and it would work from anywhere or perhaps _root.red....
I've tried root. stage. childbyname Not sure where to from here.

i've made a simple example here to show you my problem. I have basically created a stage object ("box"), with the nested children, box->b->c. I have exported box for as, with class "box" and base class movieclip. Now i create 4 instances of my box class and add an eventlistener to the nested child c. When i later on try to remove the eventlisterner for myinstance.b.c i get: TypeError: Error #1010: term is undefined and has no properties.at DocumentClass/removeSomething(). Here is my code:

I have a flex application with two objects: a parent widget (called an IBaseWidget) and a child widget (called a HelperWidget2).When the user clicks on a help link, a helper widget is loaded into the list of base widgets and then displayed for the user.However, when I try to access this child widget by casting the base widget in the collection to the child widget type,the child widget returns null and I am unable to work with the widget.The following snippet correctly returns the widget ID of the newly added widget and dispatches an event to load the widget:
var id:Number = WidgetManager.getInstance().getWidgetId("Helper");
ViewerContainer.dispatchEvent(new AppEvent(AppEvent.WIDGET_RUN, id, openQuickQueryCanvas));[code].........
The problem is that helperWidget above always returns null, meaning the cast isn't successful.

I am trying to add a child in a movie clip and perform basic operations on the child but I cannot get access to the child.
It loads the child to the movieclip "FLine1MC" but it says FLine1MC.ClipArt1 does not exist when I try to change the x location.
function AddArt1(evt:MouseEvent): void {
var ClipArt1Request:URLRequest = new URLRequest("images/mypic.gif");
var ClipArt1:Loader = new Loader();
ClipArt1.load(ClipArt1Request);
FLine1MC.addChild(ClipArt1);
FLine1MC.ClipArt1.x = 550;
}
Anybody know what's my error?
By that token, is there a way we can check the exact path of an object?

I am adding a movieclip in a class I will call class B that is added to a class I will call class A. In class B I am adding the movieclip like this:
var thumbHolder:MovieClip = new MovieClip();
thumbHolder.name = "thumb" + loadingCount;
MovieClip(root).slideMenuHolder_mc.slideMenu.thumbs_mc.addChild(thumbHolder);
trace("after: thumbHolder.name is: " + thumbHolder.name);
In class A, I can do something like this:
thumbs_mc.alpha = .3;
But if I try to do something like this, I get an error, even though the trace above traces out the names correctly. thumbs_mc.thumb1.alpha = .3;
