Resize of Output-Records

Sorry if this is a FAQ. But I am a clim-newcomer.

I am searching for a (very) efficient way to code a function like

   clim:dragging-output-record stream output-record
                                    & key (:repaint t)

   which enters an interaction mode in which the user moves the
   pointer, and output-record is RESIZED (and not dragged !!!) on
   stream when the pointer is moved.


 *** Especially, I have tried to code a function called
     tracking-pointer-and-draw-rubber-band-rectangle (stream)

     which should track the pointer on stream and draw a rubber-band
     on it, i.e.,
        * create a visible rectangle on a button-press event
        * resize this rectangle when the user moves the pointer AND
          ensure that all displayed contents of windows are NOT
          disturbed as the rubber-band is resized (c.f. drawing-programs)
        * finish drawing on a button-release event; the rubber-band
          should be removed from the stream, i.e., it is not visible then.

     Since I have not enough experience to code an efficient function for
     this (simple ?) problem, I ask for a detailed example of a possible
     solution. Can I use clim:dragging-output-record?

Thanks a lot,
