The Scope of a Data Source

A data source can be accessed either by the gadgets in its own panel or by gadgets in other panels. A data source can be accessed by gadgets located in other unrelated panels only if it has global scope. The class has two member functions, hasGlobalScope and setGlobalScope, that let you determine and set the scope of a data source. See the IliDataGem class in the Views Data Access Reference Manual.

The precise rules by which a data source is accessed are found in the section The Repository.
