Added a button to remove a bookmark. (remove_bookmark_button_clicked_cb):
2003-10-14 Federico Mena Quintero <federico@ximian.com> * gtkfilechooserimpldefault.c (create_shortcuts_tree): Added a button to remove a bookmark. (remove_bookmark_button_clicked_cb): New callback. (shortcuts_append_bookmarks): Show/hide the bookmarks buttons here, rather than in create_shortcuts_tree(). (shortcuts_append_path): Return whether the operation succeeded. (shortcuts_selection_changed): Set the sensitivity of the button used to remove a bookmark. (shortcuts_append_bookmarks): Do not select the shortcuts folder here; let the caller do it if needed. (create_shortcuts_tree): Select the shortcuts folder here. (bookmarks_changed_cb): Likewise. (create_shortcuts_tree): Also set the sensitivity of the bookmarks buttons. (bookmarks_check_add_sensitivity): Renamed from check_bookmarks_sensitivity(). (shortcuts_select_folder): Renamed from select_shortcuts_folder(). (bookmarks_check_add_sensitivity): The current_path may not be set yet. (shortcuts_append_bookmarks): Oops, remove all the bookmark rows, not just the separator node. (bookmarks_changed_cb): Set the sensitivity of the bookmarks buttons.
