Fixed a FIXME comment.
2000-05-16 Christopher James Lahey <clahey@helixcode.com> * e-table-sorted-variable.c: Fixed a FIXME comment. * e-table-header.c, e-table-header.h: Added code to put off size calculation to the idle loop. Added code to not resize columns with 0 expansion. Removed the set_width function; it's been replaced with a Gtk+ arg. * Makefile.am: Added e-table-defines.h to the Makefile.am. * e-table-defines.h: A new file containing some #defines for use in ETable. svn path=/trunk/; revision=3077
