NavigationView
Extends Composite
A widget that displays a stack of pages with a toolbar that allows to navigate back. The toolbar also displays the current page’s title and the highest priority actions that are added to the NavigationView. Only children of type Page, Action and SearchAction are supported. Since the NavigationView does not compute its own size, the width and height must be defined by the respective layout properties (e.g. either width or left and right must be specified).
Import this type with “const {NavigationView} = require('tabris');”
