Display programming
A. A shape defining the border of the pictureScreen display object container B. Four display object containers that are children of the
pictureScreen object
In order to have a display object appear in the display list, you must add it to a display object container that is on the
display list. You do this by using the addChild() method or the addChildAt() method of the container object. For
example, without the final line of the following code, the myTextField object would not be displayed:
var myTextField:TextField = new TextField();
myTextField.text = "hello";
this.root.addChild(myTextField);
A B
In this code sample, this.root points to the MovieClip display object container that contains the code. In your actual
code, you may specify a different container.
Use the addChildAt() method to add the child to a specific position in the child list of the display object container.
These zero-based index positions in the child list relate to the layering (the front-to-back order) of the display objects.
For example, consider the following three display objects. Each object was created from a custom class called Ball.
