Cut and pasted the gtkclist widget into nautilus. Fixed bugzilla.eazel.com
2000-09-21 Rebecca Schulman <rebecka@eazel.com> Cut and pasted the gtkclist widget into nautilus. Fixed bugzilla.eazel.com 481, to reflect user file filtering preferences in directory counts, and in the process, fixed bug 480. * configure.in: * cut-n-paste-code/widgets/.cvsignore: * cut-n-paste-code/widgets/Makefile.am: * cut-n-paste-code/widgets/gtkclist/.cvsignore: * cut-n-paste-code/widgets/gtkclist/Makefile.am: * cut-n-paste-code/widgets/gtkclist/gtkclist.c: * cut-n-paste-code/widgets/gtkclist/gtkclist.h: (COLUMN_FROM_XPIXEL), (LIST_WIDTH), (gtk_clist_get_type), (gtk_clist_class_init), (gtk_clist_set_arg), (gtk_clist_get_arg), (gtk_clist_init), (gtk_clist_construct), (gtk_clist_new), (gtk_clist_new_with_titles), (gtk_clist_set_hadjustment), (gtk_clist_get_hadjustment), (gtk_clist_set_vadjustment), (gtk_clist_get_vadjustment), (gtk_clist_set_scroll_adjustments), (gtk_clist_set_shadow_type), (gtk_clist_set_selection_mode), (gtk_clist_freeze), (gtk_clist_thaw), (gtk_clist_column_titles_show), (gtk_clist_column_titles_hide), (gtk_clist_column_title_active), (gtk_clist_column_title_passive), (gtk_clist_column_titles_active), (gtk_clist_column_titles_passive), (gtk_clist_set_column_title), (gtk_clist_get_column_title), (gtk_clist_set_column_widget), (gtk_clist_get_column_widget), (gtk_clist_set_column_justification), (gtk_clist_set_column_visibility), (gtk_clist_set_column_resizeable), (gtk_clist_set_column_auto_resize), (gtk_clist_columns_autosize), (gtk_clist_optimal_column_width): * src/file-manager/Makefile.am: Add include of the cut-n-paste-code directory, so we can access the clist. * libnautilus-extensions/Makefile.am: include the new static gtkclist library * libnautilus-extensions/nautilus-list.h: include the cut and pasted widget instead of the gtk one. * libnautilus-extensions/nautilus-directory-async.c: (get_filter_options_for_directory_count), (start_getting_directory_counts): Add command to get filtering options for gnome-vfs based on user preferences. This works niftily when preferences change thanks to the callbacks in fm_directory_view
