This one derives from e-cell-toggle.
1999-11-30 Miguel de Icaza <miguel@gnu.org> * e-cell-checkbox.c (e_cell_checkbox_new): This one derives from e-cell-toggle. * check-emtpy.xpm, check-filled.xpm: new files. * e-cell-toggle.c (etog_draw): Paint in white. If we have transparency enabled, do the nice alpha computation. * test-table.c, test-cols.c: new files; They implement the split tests. svn path=/trunk/; revision=1447
