Add row_draggable() vfunc, and wrapper function.

Browse Source 
Mon Nov  5 22:34:29 2001  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtktreednd.[ch] (struct _GtkTreeDragSourceIface):
	Add row_draggable() vfunc, and wrapper function.

	* gtk/gtktreednd.[ch] (struct _GtkTreeDragDestIface): Make
	row_drop_possible take a GtkSelectionData, rather than
	model/row pair.

	* gtk/gtktreestore.c gtk/gtkliststore.c: Update for
	new DND interfaces.

	* gtk/gtktreeview.[ch]: Remove the row_draggable_func
	location_dropable_func from gtk_tree_view_set_rows_drag_source/dest.
	and rename them to enable_model_drag_source/dest.

	* gtk/treeviewcolumn.c: Add DND of columns between rows.
	Still can't drop _to_ the left tree, but other places
	work.

	* gtk/gtktreeview.c (unset_reorderable): Unset the
	reorderable property if unset/enable_model_drag_source/dest
	are called manually.

	* gtk/gtktreestore.c (gtk_tree_store_row_drop_possible):
	Correct for change in depth count handling.

	* gtk/gtktreeview.c (gtk_tree_view_create_row_drag_icon):
	Pass in a expose area to gtk_tree_view_column_cell_render()
