How do you Capture Mouse?

Question

I'm new at Flex and trying to make a graphics editor for which I need the user to be able to resize the graphs the same way most graphics editors do - with a resize box. So what I'm making now is a class (that extends UIComponent) that have 4 little squares (that extend UIComponent too) at the corners that the user should use as handles to resize something. So I all need to do right now is to make them react properly to mouse inputs: the one at the top right should have the same "x" position as the one at the bottom right if the user is moving the bottom right one and so on. What I do is call startDrag in the MOUSE_DOWN event for each square and then in the MOUSE_MOVE event I move the others squares accordingly. The problem is that the square being dragged moves faster than all the others. If I could just capture mouse and then do all the dragging stuff myself that would make it a lot easier. But it seems that they didn't implement that function so, does anyone know any other possible way to do what I'm trying to do?

Solved my problem. Here's the code in case is useful for anyone:
// Make an event listener like this for every mouse event
public function OnMouseDown(event:MouseEvent):void
     if(event.target is DisplayObject){
          if(!MouseOwner.contains(DisplayObject(event.target))) event.stopPropagation();
     else event.stopPropagation();
public function CaptureMouse(Element:DisplayObjectContainer):void
    this.addEventListener(MouseEvent.MOUSE_DOWN, OnMouseDown, true);
    // Keep adding listeners for every mouse event
    MouseOwner = Element;
