gtk2/gtk/gtkfilechooserdefault.c
Federico Mena Quintero aa22566e6c Connect to "row_activated" on the file list. (list_row_activated): New
2003-09-10  Federico Mena Quintero  <federico@ximian.com>

	* gtkfilechooserimpldefault.c (create_file_list): Connect to
	"row_activated" on the file list.
	(list_row_activated): New function.  Changes to folders or emits
	the "file-activated" signal depending on what type of row was
	activated.
	(create_folder_tree): Renamed from create_directory_tree(), since
	"folder" is the new politically-correct name.

	* gtkfilechooserprivate.h (struct _GtkFileChooserIface): Added a
	file-activated signal.

	* gtkfilechooser.c (gtk_file_chooser_class_init): Register the
	signal.

	* gtkfilechooserutils.c (_gtk_file_chooser_set_delegate): Connect
	to "file-activated" on the delegate.
	(delegate_file_activated): New function.

	* TODO: Added an API item about Clipart-like folders provided by
	applications.
