[xHarbour-developers] How to subclass a GT?

[Vicente Guerra]

     Hi!

     How can I "subclass" a GT?

     I can't found how could be the right way :-( I did it:

INIT PROCEDURE LOAD_OWNCGI
    HB_INLINE(){
       PHB_GT_BASE curGT;

       hb_gtRegister( &gtInit );

//      hb_gtLoad( "CGI", NULL );     // CGI already loaded.
       curGT = hb_gt_Base();

//      memcpy( HB_GTSUPER, curGT->pFuncTable, sizeof( HB_GT_FUNCS ) );

       hb_gtLoad( "OWNCGI", curGT->pFuncTable );
    }
RETURN

     First, I can't found how to obtain CGI's pFuncTable in a safe way,
or how to assign it to my own SUPER table.

     Each call to hb_gtLoad() destroys SUPER' and SELF' pFuncTable .
That means if I call hb_gtLoad("OWNCGI") again, I will lost it.

     And, HB_GTSELF_INIT() is only called at program startup. My GT is
not initialized :(

     Where am I wrong? Is GT-subclass a work in progress? Or, is it
not implemented yet, but structure is pre-designed for that?

     Thanks in advance.

Atte.
