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);
Barry.
