		-- that have decorations. Can also be consulted in other 
		-- containers,	it will simply return "0x0".
		-- This attribute can be used in conjunction with the POSITION 
		-- attribute of a child so the coordinates of a child relative to 
		-- the native parent can be obtained.
   	-- The returned values are integer corresponding to the horizontal 
		-- and vertical offsets, respectively, in pixels.
		-- This is a read-only attribute.
