public class TabContainerWidget
extends BaseApplicationWidget
implements TabContainerContext, TabRegistrationContext

This class represents a UI widget that contains tabs (TabWidget)s. Only one tab can be selected (active) at a time, such tab is specified with selectTab(String). When on creation the selected tab is not specified, the first tab is marked as selected. Tabs are added with addTab(String, String, Widget), removed with removeTab(String) and disabled (user cannot select them) with disableTab(String). By default tabs preserve the addition order and are also presented in that order. When this TabContainerWidget has a Comparator set, it will sort and present the tabs in an order specified by that Comparator.

1.1
