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 providing an interface to an application for monitoring execution of the application. An event generated by a view controller is detected, wherein the view controller handles presentation of a container in a graphical user interface. A determination is made as to whether the event is an event selected for monitoring. Responsive to the determination that the event is an event selected for monitoring, a request event is generated, wherein the request event includes data from the event and a destination.

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 processing user input in a graphical user interface. A graphical user interface is presented using a view controller, wherein the view controller handles the user input to the graphical user interface. Responsive to a selected user input, an event is sent to a first application mediator. Responsive to the first application mediator being unable to process the event, the event is sent to a second application mediator for processing, wherein the first application mediator and the second application mediator handle an order in which a set of displays are displayed by a view controller.

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.

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.

Abstract: A process in a data processing system for handling messages received in a message queue in a message handling process for a graphical user interface. In response to receiving a message in the queue, a determination is made as to whether the error is a message. In response to an identification of an error message, that message is intercepted before processing by the message handling process. A determination is made as to whether a corrective action is required in response to the error message and as to whether the error message should be reformatted. If corrective action is required, that action is initiated by the process. Additionally, if the message should be reformatted, the process then reformats the message and returns the message to the message handling process for further processing.

Abstract: A process for use in a data processing system to define a display area within a display device in the data processing system. The display device includes an unviewable portion and a viewable portion in which a plurality of borders define the viewable portion of the display. The process includes displaying a line or some other graphical object parallel to the border within the plurality of borders in the display device. The line is moved relative to the border in response to a user input wherein the line remains parallel to the border. The line is fixed in response to a second user input. Additional lines are displayed, moved, and fixed for the remaining borders forming the viewable portion of the display, resulting in the definition of a display area. This display area is stored and employed to display data on the display device such that data is not displayed in the unviewable portion of the display device.
