Added start_drag signals.
2001-08-24 Christopher James Lahey <clahey@ximian.com> * e-table-group-container.c, e-table-group-leaf.c, e-table-group-leaf.h, e-table-group.c, e-table-group.h: Added start_drag signals. * e-table-item.c, e-table-item.h (eti_event): Send the start_drag signal. Fixes Ximian bug #807. * e-table.c, e-table.h, e-tree.c, e-tree.h: Added start_drag signal. Made default handler start drag & drop if we're set to automatically handle dnd. Ripped out the code to handle watching events for dnd since start_drag does this now. svn path=/trunk/; revision=12437
