There's a substantial difference in how you instantiate an object. If you want it to be visible, it must be a form or belong to a form (not necessarily directly to a form, but still; also, _screen is a form). If you call a createobject() or newobject() functions, you'll get invisible objects. You may assign references to these invisible objects to properties of a form (or any object on it), it still won't make them visible, and they won't have a parent (i.e. .parent=null).

The only way to have a visible object is to either have it on a form at design time, or to use .addobject() or .newobject() methods of a visible (*) object, which will then be the parent of this object.

(*) I guess the word I would rather have used would be "visiblable" - one that can be made visible.
