2005-07-14  Federico Mena Quintero  <federico@ximian.com>

	Add overwrite confirmation for SAVE mode.  Fixes bug #152850:

	* gtk/gtkfilechooser.h: Add prototypes for
	gtk_file_chooser_set/get_do_overwrite_confirmation().
	(GtkFileChooserConfirmation): New enum for the result of the
	"confirm-overwrite" signal.

	* gtk/gtkmarshalers.list: Add ENUM:VOID.

	* gtk/gtkfilechooser.c (gtk_file_chooser_class_init): Add a
	"do-overwrite-confirmation" boolean property.
	(gtk_file_chooser_set_do_overwrite_confirmation): Implement.
	(gtk_file_chooser_get_do_overwrite_confirmation): Implement.
	(confirm_overwrite_accumulator): New accumulator for the signal.

	* gtk/gtkfilechooserutils.h (GtkFileChooserProp): Add
	GTK_FILE_CHOOSER_PROP_DO_OVERWRITE_CONFIRMATION.

	* gtk/gtkfilechooserutils.c
	(_gtk_file_chooser_install_properties): Override the
	do-overwrite-confirmation property.

	* gtk/gtkfilechooserprivate.h (struct _GtkFileChooserIface): Add a
	confirm_overwrite signal to the vtable.

	* gtk/gtkfilechooserdefault.c
	(gtk_file_chooser_default_set_property): Handle the new property.
	(gtk_file_chooser_default_get_property): Likewise.
	(get_selected_file_info_from_file_list): New helper function; code
	taken from list_selection_changed().
	(list_selection_changed): Use get_selected_file_info_from_file_list().
	(should_respond_after_confirm_overwrite): New function.
	(gtk_file_chooser_default_should_respond): Confirm when necessary.
