2000-01-27 John Sullivan <sullivan@eazel.com>
More work towards changing the sorting framework, and
fixed some bugs in nautilus_file_get.
* libnautilus/nautilus-directory.h:
Added NautilusFileSortType enum.
(nautilus_file_compare_for_sort): New function
(nautilus_file_compare_for_sort_reversed): New function
* libnautilus/nautilus-directory.c:
(nautilus_file_ref): New function (prototype already existed).
(nautilus_file_get): file_info had been stack variable,
but that didn't work right, so now it's xxx_new()ed.
Also ref'ed file before returning.
(nautilus_file_compare_for_sort),
(nautilus_file_compare_for_sort_reversed),
(nautilus_file_compare_for_sort_internal): New functions.
(nautilus_self_check_directory): Added some simple tests for
nautilus_file_get and nautilus_file_compare_xxx.
* src/file-manager/fm-directory-view.c:
(fm_directory_view_load_uri): Removed sort_rules that were
passed in to gnome_vfs_asynch_load_directory_uri, since they
had no effect and we're changing the sorting framework.
2000-01-27 Elliot Lee <sopwith@redhat.com>
* libnautilus/Makefile.am: Link to $(BONOBO_LIBS)
* libnautilus/gnome-icon-container.c: Include <string.h> to get prototype for memset.
* libnautilus/gnome-icon-container.c: Include <string.h> to get
prototype for memset.
