trying to undraw

now there is no error, but I can't get objects to be undrawn
redrawing on "l" key press and moving to the right

but its making a new drawing.
Have to work on erasing previous objects
stable version

working on object attach and detach, so there are no trails of objects
commit hickup
redrawing with "l" again
redesign way cubies store each obj, to be drawn

its drawing and undrawing
but then.. it does not draw again.
It seams DetachObject is loosing the object also
new version for draw and undraw.."l" not working

its drawing bylooking at a **of objects... created when
cubie.setObjects(), after Puzzle loadsPieces(ySlicer->getPieces())  on
main.
its working ok.. BUT!!!
its not redrawing!!! at least its not breaking
changed cubies creation

cubies now get created as new, whenever a boolean happens.
Puzzle is creating new cubies on each loadPieces()
yes!! drawing controled

Now its drawing, undrawing, and moving to the left without leaving a
trace
