I have a document class called Main, and a class called DispatchEventExample. In DispatchEventExample, I'm trying to add an event listener to the stage but get an 1120 error, access of undefined property stage.
If I understand things correctly, even though I create an instance of DispatchEventExample in Main, it's not added to the display list & therefore cannot access stage.

I have a class that have a method to do some work and return a MovieClip. How can I access the stage from the class ? I don't add the class object to stage.
My code is like this :
Code:
import com.ClassName
.
.
.
var c:ClassName= new ClassName();
var mc:MovieClip;
mc = ClassName.create("some parameter");
I want to get access to the stage from ClassName class file.
I'm currently trying to add the resulting XML (xmlResult) to a textbox that is on the stage. I did try using MovieClip(root).[instancename].text = ..... however it didn't work - null object reference?
package {
public class ChatHistory extends MovieClip {
public function ChatHistory()

How to access a display object on the stage in a class which is not a document class?
I am looking for a solution that doesn't involve passing the stage as a parameter to the class.
One solution i always come across is using "TopLevel.as". Is it a good method because as far as I have heard using global variables is not recommended because it might cause some problems while working on big projects.
I was wondering how do you access the stage property from a different class that's not the principal class tied to the fla? Essentially, I have main.as which calls another class menu.as, and I can't seem to be able to use the stage.stageWidth property from menu.as. What's the proper way to be able to use the stage property from any class? Do I have to import it separately each time?
View 2 RepliesIf I have three classes:
public class Example {
public function Example () {
}[code]............
You can see that the two last classes extend the first one, and both have the 'variable' property. In case that I have an instance of Example and I am sure it is also an ExtendedExample OR AnotherExtendedExample instance, is there some way to access the 'variable' property? Something like
function functionThatReceivesAnExtendedExample (ex:Example):void {
if(some condition that I may need) {
ex.func()
i am trying to access an object within a class and the object is comming up as null but i dont understand why.
this is the object:

i am trying to access an object within a class and the object is comming up as null but i dont understand why.this is the object:
btnLMain = new MovieClip(); //variable declared earlier in code
btnLMain.name = "btnLMain";
btnLMain.clickNum = 0;
addChild(btnLMain);
this was created in the class: LanguageButton. here is how i declared the above class within the class i am trying to instantiate it:
var btnL:LanguageButton;
then i try to access the btnLMain from the LanguageButton Class and it, (btnLMain) is comming out null:
btnL = new LanguageButton(cssLoader);
main.addChild(btnL);
btnL.btnLMain.addEventListener(MouseEvent.CLICK, btnLClick);
Ok. So heres what I am trying to do. I want one movie clip to follow another one that I move around with actions on the main timeline.The problem is that the follower clip is linked to a class file and I cannot find a way to find the players position.

I have created a class, call it Class1, that has various objects drawn on the stage (drawn in the IDE). It also has a function, called setColour, for changing the colour of those objects. The function works fine if I call it from within Class1.
Now I have another class, call it testClass1, that imports Class1 and calls the setColour function. First of all, none of the stage objects from Class1 are visible. Secondly, when setColour tries to modify the colour of an object, I get the error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
This is the code for testClass1:
ActionScript Code:
package
{
import flash.display.*;
[Code].....
So, what is the problem? Is it possible to change objects that are drawn on the stage of an imported class?
The following is that long only because I gave examples of what I want to know, not because it is complex .I have three basic questions regarding AS 3.0 classes.
1. How can I make a class object interact with an object on stage?
For example, when I have a square (mc_Square) with class "square" attached to it and I want it to trace "Colliding!" and print the X and Y of the mc_Box on contact with an on-stage *hollow* box (mc_Box) that has no class attached to it.how to do it vice-versa would also be awesome .
2. How can I make a class object interact with the same class object? For example, when I have two squares (mc_Square) that both have the class "square" attached to it and when they collide, it prints the X and Y of both of them.
3. How can I make a class object interact with a different class object?
For example, when I have two squares mc_Square1 with class "square1 (that also has a variable Primary=true written in it)" and a mc_Square2 with class "square2"; When they collide, the one with Primary=true would be removed and it's X,Y position traced.
I have a MC, instance name "jez_mc" this is inside an MC, instance name "container_mc". container_mc on on the stage.I then have an MC dynamically added to the stage. In this MCs timeline I want to access a variable stored in the class that is linked to jez_mc. This var that I want is named "score"So i figured in my timeline I could use something like:
var _jez_mc:MovieClip;
_jez_mc = MovieClip(root).container_mc.jez_mc;
trace("_jez_mc.score");

I'm trying to access a MovieClip created within the authoring tool from an ActionScript class. Here is my code:
PHP Code:
package {
import flash.display.*;
public class MoreVideos extends Sprite {
[Code].....
I also tried changing that to [stage.moreVideosBox.visible = false;], but I then got "1119: Access of possibly undefined property moreVideosBox through a reference with static type flash.display:Stage."
Is it possible to directly alter items in the authoring tool from a class? If I move 'moreVideosBox.visible = false;' outside of the class, in the main .as file, it works fine.
i have textfield myTxt on stage, and i have Room.as class file.
Actionscript Code:
package { public class Room { public function Room() { // constructor code myTxt.text = "yo!"; }
I need to access objects on stage from within class.
This is for AIR: My document class imports a separate class "ConnMonitor" and uses it to constantly monitor the network connection. It's at the very end of that class where it's supposed to update a textfield on the stage as the connection changes, but the class can't access the textfield.

Also, can I pass the MovieClip from the Document Class to another custom Class?
