# This is the Qt ListModel that contains all welcome pages data. Each page is a page that can be shown as a step in the
# welcome wizard dialog. Each item in this ListModel represents a page, which contains the following fields:
#
# - id : A unique page_id which can be used in function goToPage(page_id)
# - page_url : The QUrl to the QML file that contains the content of this page
# - next_page_id : (OPTIONAL) The next page ID to go to when this page finished. This is optional. If this is not
# provided, it will go to the page with the current index + 1
# - should_show_function : (OPTIONAL) An optional function that returns True/False indicating if this page should be
# shown. By default all pages should be shown. If a function returns False, that page will
# be skipped and its next page will be shown.
#
# Note that in any case, a page that has its "should_show_function" == False will ALWAYS be skipped.
