Fix https://bugzilla.novell.com/show_bug.cgi?id=184875 - make the location

2006-07-18  Federico Mena Quintero  <federico@novell.com>

	Fix https://bugzilla.novell.com/show_bug.cgi?id=184875 - make the
	location entry in Save mode preserve the stuff from
	set_filename(); it was overwriting it with $cwd.

	This is the same fix for
	http://bugzilla.gnome.org/show_bug.cgi?id=347066

	* tests/autotestfilechooser.c: (test_black_box): Added black-box
	test for set_filename() and set_current_name().

	* gtk/gtkfilechooser.c (gtk_file_chooser_get_type): Cast to
	GClassInitFunc in the call to g_type_register_static_simple(), to
	avoid a compiler warning.

	* gtk/gtkfilechooserprivate.h (struct _GtkFileChooserDefault):
	Added a browse_files_last_selected_name field.  We'll copy the
	logic from gtkfilesel.c to see when to clear the location entry.
	(struct _GtkFileChooserDefault): Removed the
	processing_pending_selections field.

	* gtk/gtkfilechooserdefault.c (gtk_file_chooser_default_finalize):
	Free impl->browse_files_last_selected_name.
	(pending_select_paths_process): Don't use
	impl->processing_pending_selections.
	(update_chooser_entry): Keep track of the name that was last
	selected in the file list.  We use this to know when to clear the
	location entry.  The logic is similar to that of
	gtkfilesel.c:gtk_file_selection_file_changed().  This also lets us
	get rid of the processing_pending_selections flag.
	(update_chooser_entry): Clear the entry if we didn't have a
	selection before.
	(location_switch_to_filename_entry): Do not set $cwd as the
	contents of the location entry here...
	(location_popup_handler): ... but do it here instead, only as the
	result of the user asking to turn on the location entry.
	(gtk_file_chooser_default_get_paths): If the location entry is
	empty, do the fallback of seeing if it is sensible to say that
	$cwd is the selected path.
	(gtk_file_chooser_default_update_current_folder): Don't set the
	text of the location entry; this is no longer needed with the
	fixes above.
	(shortcuts_activate_iter): Clear the location entry when
	activating a shortcut if we are not in SAVE mode.  This keeps the
	contents of the location entry consistent even when switching
	folders via the shortcuts.
