The Ribbon is comprised of tabs. Each tab contains bar items that allow end-users to accomplish a common task. To further categorize related bar items within a tab, items are organized into groups.
Tabs are represented by TdxRibbonTab objects that can be accessed via the Ribbon’s Tabs property. Our Ribbon implementation provides a comprehensive tab management API which is outlined below.
