Abstract: A method and apparatus in a data processing system for displaying a component or container. The container is displayed within a display using a first component. A location of the component or container is controlled within the display using a second component, wherein the second component controls the location and geometry of the component or container in response to receiving an event. The component or container is selectively displayed using a third component, wherein the third component generates the event.

Abstract: A method and apparatus in a data processing system for managing transactions. A request event is received at a transporter object. The request event includes a target and an indication of how to handle the request event. A destination object is identified within the plurality of destination objects using the request event to form an identified destination object. The request event is sent to the identified destination object, wherein the identified destination object handles the request using the indication and accesses the target.

Abstract: A method and apparatus of an architectural pattern for creating applications for a data processing system. A graphical user interface is created in which the graphical user interface includes a plurality of components. Processes for presenting the plurality of components and receiving user input are handled by a first set of graphical objects, wherein in response to selected user input, a first event is generated. An application object is created in which the application process controls an order in which the graphical objects present the set of components and process the event and wherein the application generates a second event. A transport object is created in which the transport object processes the second event and forwards the second event for processing to a destination within the plurality of destinations. A plurality of destination objects are created in which each destination object within the plurality of destinations objects handles accessing a destination within the plurality of destinations.

Abstract: A method and apparatus in a data processing system for managing permissions in an application. A user input is received at a container handled by a view controller, wherein the user input requests a change in permissions in the application. This user input, may be, for example, a change in security in an application through a login process. A view event describing the user input is generated. The view event is received at an application mediator. Responsive to receiving the view event, by the application mediator, a request event is generated and a permission corresponding to the user input is received. The permission alters an item, which may be in either of both the view controller and the application mediator.

Abstract: A method and apparatus in a data processing system for dispatching events. An event from a first object is received. A type for the event is identified. A dispatching strategy is selected for the event based on parameter settings, a source of the event, and default settings to form a selected dispatching strategy. The event is dispatched using the selected dispatching strategy.

Abstract: A method and apparatus in a data processing system for refreshing data in an application. A call is received to update data in the application, wherein the data is destined for a component in the application. A data type is identified for the data. Responsive to the data type being a handled data type, the data is formatted and a refresh is called on the component.

Abstract: A method and apparatus in a data processing system for displaying a graphical user interface. A container is displayed in a graphical user interface from a set of containers, wherein a display of the container handled by a view controller from a set of view controllers. Each view controller handles the display of an associated container within the set of containers and user input for the associated container. A display of the set of containers is altered by an application mediator, wherein the set of containers are displayed in an order determined by the application mediator.

Abstract: A method and apparatus for a data processing system for accessing classes and methods in an object oriented system. Responsive to receiving a selected user input to a container, a view event is sent from a view controller to an application mediator. The view event identifies an action taken to generate the selected user input. A request is selectively generated based on the view event, wherein the request event includes a major code identifying a class name as a destination and a minor code identifying a method name a function to be invoked. The request event is sent to a transporter. The transporter acts as a router to send the request event to an appropriate destination object from a plurality of destination objects. Responsive to receiving the request event at the transporter, the request event is sent to a destination object within a plurality of destination objects based in the class name.

Abstract: A method and apparatus in a data processing system for serialization data. A serializer receives a data element for serialization, wherein the data element includes a class name string. Responsive to receiving the data element, the serializer replaces the class name string with a code having a smaller size than the class name string to form a modified data element. Responsive to forming the modified data element, in which the serializer serializes the modified data element. The serialized data is transmitted and deserialized by deserializer which replaces the indicator with the class name.
