Method and apparatus in a data processing system for generating alternative views of client applications

A data processing system comprising:

• a plurality of view controllers, wherein the plurality of view controllers handle presentation of an interface;
• an application mediator, wherein the application mediator handles an order in which the plurality of view controllers are displayed in a display;
• and
• a placement listener, wherein the placement listener handles placement of the interface in the display, wherein the view controller generates a first event handled by the application mediator, the application mediator generates a second event in response to the first event requiring a change by a view controller within the plurality of view controllers, wherein the placement listener sends a call to the view controller to present the container using an alternate mechanism.

A data processing system for presenting a view to a client, the data processing system comprising:

• receiving means for receiving, at an application mediator, a view event from a view controller, wherein the view event describes an action on a displayed container handled by the view controller;
• generating means, responsive to a requirement that a change in a placement of the displayed container is required, for generating a placement event by the application mediator;
• determining means for determining, by a placement listener, whether the placement event includes an indication that an alternate view is to be generated;
• and
• sending means, responsive to a determination that an alternate view is to be generated, for sending a call to a method in the view controller to generate the alternate view.

A computer program product in a computer readable medium for presenting a view in a data processing system to a client, the computer program product comprising:

• first instructions for receiving, at an application mediator, a view event from a view controller, wherein the view event describes an action on a displayed container handled by the view controller;
• second instructions, responsive to a requirement that a change in a placement of the displayed container is required, for generating a placement event by the application mediator;
• third instructions for determining, by a placement listener, whether the placement event includes an indication that an alternate view is to be generated;
• and
• fourth instructions, responsive to a determination that an alternate view is to be generated, for sending a call to a method in the view controller to generate the alternate view.

A computer program product in a computer readable medium comprising:
