A Tab contains groups of related controls.


There are three types of Tab in the Ribbon framework.

Core tabCore tabs that organize the default functions of the application.
Contextual tabTabs that are displayed during specific document or workspace states. For example, if a user selects a particular object type, such as an image contained in the header of a table, then various contextual tabs might be displayed that expose both table and image functionality.
Modal tabCore tabs that are displayed during a specific document or workspace application mode, such as print preview.

Tab Properties

The Ribbon framework defines a collection of property keys for the Tab control.

Typically, a Tab property is updated in the ribbon UI by invalidating the Command associated with the control through a call to the IUIFramework::InvalidateUICommand method. The invalidation event is handled, and the property updates defined, by the IUICommandHandler::UpdateProperty callback method.

The IUICommandHandler::UpdateProperty callback method is not executed, and the application queried for an updated property value, until the property is required by the framework. For example, when a tab is activated and a control revealed in the ribbon UI, or when a tooltip is displayed.

Note  In some cases, a property can be retrieved through the IUIFramework::GetUICommandProperty method and set with the IUIFramework::SetUICommandProperty method.

The following table lists the property keys that are associated with the Tab control.

UI_PKEY_Label Can only be updated through invalidation.
UI_PKEY_Keytip Can only be updated through invalidation.
