The NavigationBar component is used to create a navigation bar.
A navigation bar is created from vertically arranged tabs. Each tab consists of a title and a controls panel. The tab is activated on clicking its title. If required, each tab can be hidden.
Use software to create a collection of tabs for setting up the component. To create a tab, create an instance of the NavigationBarPad class and include it in the Pads collection of the NavigationBar component. For each tab set up a title (the INavigationBarPad.Header property) and a panel (the INavigationBarPad.Content property). A title can include text and a control. The panel associated with the title is a frame for the form with controls. The form identifier is specified in the INavigationBarPanel.MetabaseObject property.
