code: public void activate (Host host, Rectangle bounds, Object argument)
      {
          setActivationArgument(argument);
          activate(host, bounds);
      }
docs: Activates the radial menu, rendering a menu around the prescribed bounds. It is expected
  that the host component will subsequently call {@link #render} if the menu invalidates the
  region of the component occupied by the menu and requests it to repaint.
  
  @param host the host component within which the radial menu is displayed.
  @param bounds the bounds of the object that was clicked to activate the menu.
  @param argument a reference to an object that will be provided along with the command that
  is issued if the user selects a menu item (unless that item has an overriding argument, in
  which case the overriding argument will be used).
