Store signal IDs in gulongs, not guints!

2004-07-28 Federico Mena Quintero <federico@ximian.com> * gtk/gtkfilechooserdefault.c (struct _GtkFileChooserDefault): Store signal IDs in gulongs, not guints! (gtk_file_chooser_default_hierarchy_changed): We now monitor the focus widget on our toplevel to know which widget was last focused at the time our "should_respond" method gets called. (shortcuts_activate_selected): New helper function. (shortcuts_get_selected): New helper function. (remove_selected_bookmarks): Use shortcuts_get_selected(). (bookmarks_check_remove_sensitivity): Likewise. (shortcuts_reorder): Likewise. (shortcuts_activate_iter): Renamed from shortcuts_activate_item(). Activate by iter, not by item number. (save_folder_combo_changed_cb): Use shortcuts_activate_iter(). (shortcuts_row_activated_cb): Likewise. (gtk_file_chooser_default_should_respond): If the last focused widget on the toplevel was the shortcuts list, activate the selected shortcut.
