Adds tabs for navigating across Displays when editing a View.

This function can be called from hook_menu_local_tasks_alter() to implement these tabs as secondary local tasks, or it can be called from elsewhere if having them as secondary local tasks isn't desired. The caller is responsible for setting the active tab's #active property to TRUE.

Parameters

view $view: The view which will be edited.

$display_id: The display_id which is edited on the current request.

File

includes/admin.inc, line 1468

Provides the Views' administrative interface.
