40  * GtkAssistantPageType:
41  * @GTK_ASSISTANT_PAGE_CONTENT: The page has regular contents. Both the
42  *  Back and forward buttons will be shown.
43  * @GTK_ASSISTANT_PAGE_INTRO: The page contains an introduction to the
44  *  assistant task. Only the Forward button will be shown if there is a
45  *   next page.
46  * @GTK_ASSISTANT_PAGE_CONFIRM: The page lets the user confirm or deny the
47  *  changes. The Back and Apply buttons will be shown.
48  * @GTK_ASSISTANT_PAGE_SUMMARY: The page informs the user of the changes
49  *  done. Only the Close button will be shown.
50  * @GTK_ASSISTANT_PAGE_PROGRESS: Used for tasks that take a long time to
51  *  complete, blocks the assistant until the page is marked as complete.
52  *   Only the back button will be shown.
53  * @GTK_ASSISTANT_PAGE_CUSTOM: Used for when other page types are not
54  *  appropriate. No buttons will be shown, and the application must
55  *  add its own buttons through gtk_assistant_add_action_widget().
56  *
57  * Determines the page role inside a `GtkAssistant`.
58  *
59  * The role is used to handle buttons sensitivity and visibility.
60  *
61  * Note that an assistant needs to end its page flow with a page of type
62  * %GTK_ASSISTANT_PAGE_CONFIRM, %GTK_ASSISTANT_PAGE_SUMMARY or
63  * %GTK_ASSISTANT_PAGE_PROGRESS to be correct.
64  *
65  * The Cancel button will only be shown if the page isn’t “committed”.
66  * See gtk_assistant_commit() for details.
