## @package mlx.gui.flight
#
# The flight "wizard".
#
# This module implements the main tab of the application, the flight
# wizard. The wizard consists of \ref Page "pages", that come one after the
# other. As some pages might be skipped, the pages dynamically store the index
# of the previous page so that going back to it is simpler. The \ref
# Page.activate "activate" function is called before a page is first shown
# during a flight. This function should initialize the page's controls and fill
# it with initial data. When a page is left for the first time, its \ref
# Page.finalize "finalize" function is called. It should set those controls
# insensitive, that will not be available if the user comes back to this page.
#
# Each page has a title at the top displayed in inverted colors and a big
# font. There is a help text below it centered, that shortly describes what is
# expected on the page. There can be two help texts: one shown when the page is
# first displayed during a flight, another shown when the user goes back to the
# page. The main content area is below this, also centered. Finally, there are
# some buttons at the bottom on the right. As some buttons occur very
# frequently, there are functions to add them (\ref Page.addCancelFlightButton
# "addCancelFlightButton", \ref Page.addPreviousButton "addPreviousButton" and
# \ref Page.addNextButton "addNextButton".
#
# The \ref Wizard class is the main class to collect the pages. It also stores
# some data passed from one page to another and provides properties to access
# data items set via the wizard pages.
