2004-08-06 Federico Mena Quintero <federico@ximian.com> Fix #144232: * gtk/gtkfilechooserdefault.c (save_widgets_create): Use a GtkFileChooserEntry for the file name, rather than a GtkEntry. (update_chooser_entry): Set the contents of the file chooser entry rather than the plain entry's. (gtk_file_chooser_default_set_current_folder): Set the new folder on the save entry. (gtk_file_chooser_default_set_current_name): Set the name on the file chooser entry. (check_save_entry): Use the file chooser entry rather than the plain entry. * gtk/gtkfilechooserentry.c (_gtk_file_chooser_entry_set_base_folder): Call gtk_file_chooser_entry_changed() so that we recompute the current folder based on the new base folder.
