This IMO is the wrong approach. Such drawings tend to disappear almost 
immediately. Try to find the properties that make the control behave as 
you want.

AFAIR there exists some propery AllowAllUp (or the like). When such 
buttons are grouped, they can behave like radio buttons (exactly one 
down), or as independent up/down buttons. That's different behaviour 
from ordinary push buttons (OK, Cancel...).
