OPENLOOK-Sun/Ada Bindings

[agate!spool.mu.edu!wupost!cs.utexas.edu!utgpu!news-server.csri.toronto.ed]

Hi,

I just started working with Sun/Ada (v1.0)/VADS (6.0). 
I did some OPEN LOOK programming in C before and I am now
using the sunview Ada library provided to write OPEN LOOK
application with Sun/Ada.

I have 3 questions concerning Sun/Ada and Xview:

(1) I am having some difficulty in implementing a simple
    menu into a program. The compiler gives the following
    error messages:

        my_frame  :  xvi_frame.Frame;
        my_panel  :  xvi_panel.Panel;
        my_menu   :  xvi_openmenu.Menu;
        my_button :  xvi_panel.Panel_item;

     begin
        xv_init(XV_INIT_ARGS, argc, argv, 0);
        my_frame := xv_create(xvi_window.BASE_WINDOW, xvi_xview.FRAME,
                  ( (XV_LABEL,             svi_str("Hello World")),
                    (attr => FRAME_NO_ATTR)
                  ));

        my_panel := xv_create(my_frame, xvi_xview.PANEL,
                  ( (PANEL_LAYOUT,          PANEL_HORIZONTAL ),
                    ( attr => PANEL_NO_ATTR )
                  ));

        my_menu :=  xv_create(my_frame, xvi_xview.MENU,
---------------^A                                        ###

from file /usr/local2/SunAda/xview/xvi_av_functions.a

                  ( (MENU_TITLE_ITEM,       svi_str("First Menu" ) ),
                    (attr => MENU_NO_ATTR )
                  ) );

        my_button := xv_create(my_panel, xvi_xview.PANEL_BUTTON,
                ( ( PANEL_LABEL_STRING,        svi_str("menu title") ),
        --        ( PANEL_ITEM_MENU,           my_menu),
                  ( attr => PANEL_NO_ATTR )
                ));
                                     
                                           
    I would appreciate if someone can tell me what I did 
    wrong or points out another correct way to implement 
    a menu using Sun/Ada.




(2) I have read XView Programming V7 by Dan Heller. 
    Does anyone know if there is a similar manual for 
    using Xview on Sun/Ada ?
    (bec I am having some difficulties in understanding
     the translation of certain ada syntax)



(3) I am planning to write an entire application with
    Sun/Ada in the future (using Xview ada bindings).
    Has anyone worked with xview ada bindings before ?
    I would appreciate it if someone can tell about any 
    inconsistencies or problems that may arise.


Thank you in advance.
