I think the problem is that it is nested inside a function loadItem
(). But not entirely sure.
I am aware that this is not the best practice, so I tried moving it
out of the function, but to no avail.
I have created the code by "the book" but it still does not work.
What am I doing wrong here???

Hey Karl.
The issue you are facing is that the function on the comboListen
object
(comboListen.change) steals your scope - so you don't have any
access to
all the things you need: "picturesArry", "thumbHolder" etc.
So, you can either, forget creating an object to handle events and
just
put your "change" function right there:
function change(evt_obj:Object) {
var selectNum:Number = colorBox.selectedIndex;
if (selectNum <= 1) {
var pic = picturesArry[thumbHolder.ID][0];
thumbHolder["picture_box"].loadMovie(pic, 0);
thumbHolder.LoadVars(pic);
} else {
var pic = picturesArry[thumbHolder.ID][selectNum];
thumbHolder["picture_box"].loadMovie(pic, 0);
thumbHolder.LoadVars(pic);
}
}
colorBox.addEventListener("change", this);
Or, use the Delegate class to set the correct scope:
import mx.utils.Delegate;
var comboListen = new Object();
comboListen.change = Delegate.create(this, "onChange");
function onChange() {
var selectNum:Number = colorBox.selectedIndex;
if (selectNum <= 1) {
var pic = picturesArry[thumbHolder.ID][0];
thumbHolder["picture_box"].loadMovie(pic,0);
thumbHolder.LoadVars(pic);
} else {
var pic = picturesArry[thumbHolder.ID][selectNum];
thumbHolder["picture_box"].loadMovie(pic,0);
thumbHolder.LoadVars(pic);
}
}
colorBox.addEventListener("change", comboListen);

Hello List,
Have a little snag on my hands. I am trying to get the value of a
selected comboBox to change the picture of another MC.
My code:
var comboListen = new Object();
comboListen.change = function(evt_obj:Object) {
trace(evt_obj.selectedIndex);
var selectNum:Number = evt_obj.selectedIndex;
if (selectNum <= 1) {
var pic = picturesArry[thumbHolder.ID][0];
thumbHolder["picture_box"].loadMovie(pic,0);
thumbHolder.LoadVars(pic);
} else {
var pic = picturesArry[thumbHolder.ID][selectNum];
thumbHolder["picture_box"].loadMovie(pic,0);
thumbHolder.LoadVars(pic);
}
};
colorBox.addEventListener("change",comboListen);
thumbHolder = main MC that holds the picture and the comboBox
["picture_box"] = the picture MC inside thumbHolder that I want to
load into.
colorBox = the comboBox inside thumbHolder that I want to change
the picture MCs contents with.
FYI, by the time I get to using the listener, ["picture_box"] has
already been loaded with the first image in the array of pictures.
thumbHolder, colorBox and ["picture_box"] are dynamically loaded
onto the stage at run time.
How do I get colorBox's selection to change the picture in
thumbHolder["picture_box"]?
Any help would be greatly appreciated at this point. this is my
third day with this and I'm going crazy.
Is there something I need to import to control the comboBox?
I have
import mx.control.ComboBox;
already imported, do I need it?
