+2000-07-23 Damon Chaplin <damon@helixcode.com>
+
+ * e-cell-text.c: added a color_column where the color can be specified
+ as a string, e.g. "red" or "rgb:F/0/0".
+
+ * e-cell-text.c (ect_leave_edit): don't call unbuild_current_cell()
+ since the CellEdit struct has been freed in ect_stop_editing() and so
+ has the text.
+
+ * e-cell-text.c (unbuild_current_cell): set cell->text to NULL to make
+ sure we don't try to free it again.
+
2000-07-21 Christopher James Lahey <clahey@helixcode.com>
* e-table.h: Added some unused declarations for drag and drop
