Add a handler for "model_pre_change" and properly stop editing.
2000-08-02 Christopher James Lahey <clahey@helixcode.com> * e-table-item.c, e-table-item.h: Add a handler for "model_pre_change" and properly stop editing. * e-table-model.c, e-table-model.h: Added a "model_pre_change" signal that gets sent before any row numbers are changed. * e-table-sorted-variable.c, e-table-subset-variable.c: Emit "model_pre_change" signals as appropriate. * e-table-subset.c, e-table-subset.h: Proxy "model_pre_changed" signals. svn path=/trunk/; revision=4472
