2000-06-12 Federico Mena Quintero <federico@helixcode.com> * e-table-model.[ch]: Removed the freeze/thaw stuff for the model. As Chris wisely pointed out, having freeze/thaw on the model makes its state inconsistent from the perspective of the views. * e-table-sorted-variable.c: Do not check for a frozen model. * e-table-subset.c: Likewise. * e-table-subset-variable.c: Likewise. * e-table-example-1.c: Removed the ETableModel thaw handler. * e-table-example-2.c: Likewise. * e-table-simple.c: Likewise. * e-table-size-test.c: Likewise. * test-check.c: Likewise. * test-cols.c: Likewise. * test-table.c: Likewise. svn path=/trunk/; revision=3543
