Don't reload the current folder unnecessarily on ::map().

Browse Source 
2005-09-27  Federico Mena Quintero  <federico@ximian.com>

	Don't reload the current folder unnecessarily on ::map().

	* gtk/gtkfilechooserprivate.h (ReloadState): New enum to represent
	the reloading state.
	(struct _GtkFileChooserDefault): Added a "reload_state" field.

	* gtk/gtkfilechooserdefault.c (gtk_file_chooser_default_init):
	Initialize impl->reload_state.
	(gtk_file_chooser_default_map): Check the impl->reload_state; load
	a default folder if no folder has been set, or reload the current
	one only if we had been unmapped first.
	(gtk_file_chooser_default_update_current_folder): Set the
	reload_state to RELOAD_HAS_FOLDER.
	(gtk_file_chooser_default_unmap): Implement, and set the
	reload_state to RELOAD_WAS_UNMAPPED.
	(shortcuts_model_create): Don't call shortcuts_add_bookmarks()
	here; they'll get (re)loaded on ::map() anyway.

	* gtk/gtkfilechooserwidget.c
	(gtk_file_chooser_widget_constructor): Don't set a default folder here.

	* tests/autotestfilechooser.c (test_action_widgets): Don't take in
	a dialog; build it ourselves.
	(test_reload): New test to ensure that we don't load the default
	folder more than once, and that we reload it when
	unmapping/remapping.
	(get_impl_from_dialog): New utility function.
	(test_widgets_for_current_action): Use get_impl_from_dialog().
