Примеры

В следующем примере кода показано, как использовать DesignerVerbCollection класс . В этом примере создается новый экземпляр класса и используется несколько методов для добавления операторов в коллекцию, возврата их индекса, а также добавления или удаления атрибутов в определенной точке индекса.

// Creates an empty DesignerVerbCollection.
DesignerVerbCollection^ collection = gcnew DesignerVerbCollection;

// Adds a DesignerVerb to the collection.
collection->Add( gcnew DesignerVerb( "Example designer verb",gcnew EventHandler( this, &Class1::ExampleEvent ) ) );

// Adds an array of DesignerVerb objects to the collection.
