Fix #137520.

Browse Source 
2004-03-19  Federico Mena Quintero  <federico@ximian.com>

	Fix #137520.

	* gtk/gtkfilesystem.h (struct _GtkFileFolderIface): Added slots
	for an ::is_finished_loading() method and a ::finished_loading()
	signal at the end of the struct.

	* gtk/gtkfilesystem.c (gtk_file_folder_base_init): Create the
	"finished-loading" signal.
	(gtk_file_folder_is_finished_loading): New function.

	* gtk/gtkfilesystemunix.c
	(gtk_file_folder_unix_is_finished_loading): Implement.

	* gtk/gtkfilesystemmodel.c (struct _GtkFileSystemModelClass): New
	slot for a "finished-loading" signal.
	(gtk_file_system_model_class_init): Create the "finished-loading"
	signal.
	(struct _GtkFileSystemModel): New field
	idle_finished_loading_source.  We emit the "finished-loading"
	signal in an idle if the root folder was done loading right in
	_gtk_file_system_model_new(), so that the caller has a chance to
	connect to the signal.
	(_gtk_file_system_model_new): Connect to the normal signals of the
	folder even if the initial _list_children() fails.  Also, see if
	the folder is finished loading; connect to the "finished-loading"
	signal otherwise.
	(gtk_file_system_model_finalize): Remove the idle handler.

	* gtk/gtkfilechooserdefault.c (set_list_model): Set a busy cursor
	and connect to the model's "finished-loading" signal.
	(get_toplevel): New helper function.
	(error_message): Use get_toplevel().
	(trap_activate_cb): Likewise.
	(location_popup_handler): Likewise.
	(set_busy_cursor): New function.
	(browse_files_model_finished_loading_cb): New callback.
