DropTarget check against all objects on the stage

Question

Hey all,
Not sure the best way to do this.  I have a class we will call DropActivity, here is the code
package com.activitycontrol
          import com.activitycontrol.DropCheck;
          public class DropActivity
               // Constants:
               // Public Properties:
               // Private Properties:
               private var _selectedClip:Object;
                    // Initialization:
                    public function DropActivity(/*selectedClip:Object*/)
                    // Public Methods:
                    public function set selectedClip(selectedClip:Object):void
                              _selectedClip = selectedClip;
                    public function stopDraggingMe():void
                                   var dropCheck:DropCheck = new DropCheck();
                                   //dropCheck.checkAgainst = dropTarget.name; ///***********
                                   if (dropCheck.canBeDropped == true)
                                        _selectedClip.stopDrag();     
                    // Protected Methods:
when the stopDraggingMe() method is called from another object (code shown below) I need to see all the objects on the stage to see what objects on the stage my currently selected movie clip is over and assign it to the dropCheck.checkAgainst method (that will be checked against an array to see if it can in fact be dropped, if so set the canBeDropped value to true and therefor run the .stopDrag() ).  I have read using root is not a good coding practice in AS 3.
call to the stopDraggingme() mehod.
private function setDown(event:MouseEvent):void
                         var droppedItem:DropActivity = new DropActivity();
                         droppedItem.selectedClip = this;
                         droppedItem.stopDraggingMe();

No, I think I can use drop target, I just need to use it from the DropActivity class and not a document class. I just don't know how to use it from a non-document class.
"and you need to loop through all displayobjects to see which have a positive hitTest with your dropped object, correct?"
I am trying to say..... ok, what movie clip is currently under the one I have selected,  the drop activity class knows what object I have selcted as it is in the selectedClip variable.  so I need to find out what clip is under it ......... the light just came on!
answer duh......dropCheck.checkAgainst = _selectedClip.dropTarget.parent.name;
thanks a bunch kglad you have helped me out once again, you are the man. I might just have to buy you a beer one of these days.
