2001-10-31 Christopher James Lahey <clahey@ximian.com> * e-table-item.c, e-table-item.h: Added frozen_count variable to know not to show the cursor while a change is going on. * e-table-model.c, e-table-model.h, e-tree-model.c, e-tree-model.h: Added a model_no_change signal to pair with a pre_change if there's no change. * e-table-selection-model.h: Removed an unused frozen field here. * e-table-sorted.c, e-table-subset.c, e-table-subset.h, e-table-without.c, e-tree-memory.c, e-tree-sorted.c, e-tree-table-adapter.c: Made sure pre_changes were all matched by some change. Proxy no_change signal where appropriate. * e-tree-selection-model.c: Keep track of the frozen_count variable to know whether a change is going on. svn path=/trunk/; revision=14523
