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.
