OOUI/Layouts

Layouts do not emit events, but instead are used to arrange other widgets of arbitrary type in a way that is centrally controlled and can be updated dynamically. Layouts can also be—and usually are—combined. A form can be created by combining a FormLayout with a FieldsetLayout and FieldLayouts, for example, or a StackLayout can be used to display one PanelLayout at a time in the same region.

The library’s layouts include:
 * FieldsetLayout,
 * FieldLayout,
 * FormLayout,
 * PanelLayout,
 * StackLayout,
 * PageLayout,
 * BookletLayout,
 * IndexLayout and
 * TabPanelLayout.
