Constructor

new OO.ui.PageLayout(name, [config]) #

PageLayouts are used within booklet layouts to create pages that users can select and display from the booklet's optional outline navigation. Pages are usually not instantiated directly, rather extended to include the required content and functionality.

Each page must have a unique symbolic name, which is passed to the constructor. In addition, the page's outline item is customized (with a label, outline level, etc.) using the #setupOutlineItem method. See BookletLayout for an example.

Parameters:

Name Type Attributes Description
name string

Unique symbolic name of page
config Object optional

Configuration options
