Tab bars

PolicyCenter defines a default tab bar named TabBar. If no other tab bar is specified, then the default tab bar is used. However, if necessary, you can explicitly specify a different tab bar to show instead.

We recommend that you rely entirely on the default tab bar within the primary PolicyCenter application. You can customize the default tab bar to have it serve almost all of your needs. Consider defining a new tab bar only for special pages, such as entry points that have limited access to the rest of the application.

You rarely need to explicitly specify a tab bar to display. Instead, you almost always rely on the default tab bar TabBar. However, to override the default and specify a different tab bar, set the tabBar attribute on the location group. For example, you could set it to MyTabBar().

As you navigate to a location, PolicyCenter scans up the navigation hierarchy and checks whether a tab bar is explicitly set on a location group. If so, then that tab bar is used. If no tab bars are set, then the default tab bar is used.

For user interface clarity and consistency, we recommend that you set the tab bar only on the top-most location group in the hierarchy. However, a tab bar set on a child location group overrides the setting of its parent.

Define a tab bar with the TabBar PCF element. For example:
