	// arguments for a label and the text to set it with.  The second calls

	// argument.
	//
	// If the function passed to glib.IdleAdd() returns one argument, and
	// that argument is a bool, this return value will be used in the same
	// manner as a native g_idle_add() call.  If this return value is false,
