In-Ribbon Gallery

The In-Ribbon Gallery is a control that displays a collection of related items or Commands in the Ribbon. If there are too many items in the gallery, an expand arrow is provided to display the rest of the collection in an expanded pane.

In-Ribbon Gallery Properties

The Ribbon framework defines a collection of property keys for the In-Ribbon Gallery control.

Typically, an In-Ribbon Gallery 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 In-Ribbon Gallery control.
