Declare two 32-- primitive subprograms for the type (foundation code). 33-- 34-- Add a public child to the above package. Extend the root type with 35-- a record extension in the specification. Declare a new primitive 36-- subprogram to write to the child extension. 37-- 38-- In the main program, "with" the child. Declare an extension of 39-- the child extension. Access the primitive operations from both 40-- parent and child packages. 41-- 42-- TEST FILES: 43-- This test depends on the following foundation code: 44-- 45-- FA11A00.A 46-- 47-- 48-- CHANGE HISTORY: 49-- 06 Dec 94 SAIC ACVC 2.0 50-- 20 Dec 94 SAIC Moved declaration of Label_Widget to library level 51-- 52--! 53 54package FA11A00.CA11A02_0 is -- Color_Widget_Pkg 55-- This public child declares an extension from its parent.
