* GtkAssistantPageType:
* @GTK_ASSISTANT_PAGE_CONTENT: The page has regular contents. Both the
* Back and forward buttons will be shown.
* @GTK_ASSISTANT_PAGE_INTRO: The page contains an introduction to the
* assistant task. Only the Forward button will be shown if there is a
* next page.
* @GTK_ASSISTANT_PAGE_CONFIRM: The page lets the user confirm or deny the
* changes. The Back and Apply buttons will be shown.
* @GTK_ASSISTANT_PAGE_SUMMARY: The page informs the user of the changes
* done. Only the Close button will be shown.
* @GTK_ASSISTANT_PAGE_PROGRESS: Used for tasks that take a long time to
* complete, blocks the assistant until the page is marked as complete.
* Only the back button will be shown.
* @GTK_ASSISTANT_PAGE_CUSTOM: Used for when other page types are not
* appropriate. No buttons will be shown, and the application must
* add its own buttons through gtk_assistant_add_action_widget().
*
* An enum for determining the page role inside the #GtkAssistant. It's
* used to handle buttons sensitivity and visibility.
*
* Note that an assistant needs to end its page flow with a page of type
* %GTK_ASSISTANT_PAGE_CONFIRM, %GTK_ASSISTANT_PAGE_SUMMARY or
* %GTK_ASSISTANT_PAGE_PROGRESS to be correct.
*
* The Cancel button will only be shown if the page isn’t “committed”.
* See gtk_assistant_commit() for details.
