harbour-core/harbour/source/rtl/tgetlist.prg
Viktor Szakats 9efbde5b70 2004-02-15 05:12 UTC+0100 Viktor Szakats <viktor.szakats@syenar.hu> 
* source/rtl/tbrowse.prg
     ! Fixed color handling to take into account ::defcolor
       of TBColumn. Now TBrowse coloring is C52 compatible.
       For speed wierd cases are not handled like if the value
       of ::defcolor is improper.

   * source/rtl/tgetlist.prg
   * source/rtl/ttopbar.prg
   * source/rtl/tbrowse.prg
     ! DevPos() -> SetPos() (TBrowse() had plenty of them)
     ! Few missing color params added to DispOut*()
