1. Rich Client Implementation Patterns rgo Ringo Aqris Software

2. Complexity Classical web app client Rich client 3.

Rich clients have more state

AMS2.0 Model for week view 4. GUI complexity boosters

Distribution of business domain code among client and server

5. Remote IO 6. Custom widgets 7. UI state synchronization 8. MVC(1)

Model

is the application without UI

9. contains all application state 10. may communicate with DB or server View 11. Controller

adapts events from View to Model API

12. doesn't contain any business logic 13. MVC(2)

+ Model is separated

14. + Controller can be testable 15. - Controller and View are tightly coupled 16. - View update logic cannot be tested 17. Model-View-Presenter with Supervising Controller

+ Complex View update logic is testable

18. - View and Controller even more coupled 19. MVP with Passive View

+ Even more View update logic is testable

20. - Controller is even more coupled to View 21. Presentation Model

+ View update logic is testable

22. + Controller can be testable 23. - Model has more knowledge about UI 24. Distribution of complexity 25. Command

each user request is handled by separate command

26. used in Swing and SWT

+OO

27. + support for undo/redo 28. - can result in many small classes Relationship to MVC? 29. Various if(RoleManager. getCurrentRole ().equals(Role. PROJECT_OWNER )) { button.setEnabled( true ); }else{ button.setEnabled( false ); } AuthorizationManager. prepare (button, Role. PROJECT_OWNER );

Adaption

Widget assembly

panel.add( newOkCancelPanel()); panel.add(Factory. createOkCancelPanel ()); panel.add(Builder. create ( "btn:ok, btn:cancel" ));

Composable units

e.g EnterActivity MVC, ProjectViewPanel, TeamViewPanel

30. Swing

View and Controller merged into one component

31. Look-and-feel handled by separateUI delegate 32. Types of Models

GUI state (e.g ButtonModel, TreeSelectionModel)

33. application state (e.g ListModel, TableModel) 34. mixed (e.g ButtonModel if used for JCheckBox) Uses Actions (commands) public interfaceActionListenerextendsEventListener { public voidactionPerformed(ActionEvent e); } 35. Eclipse RCP

Workbench

e.g Windows, Editors, Perspectives

JFace

e.g Viewers, Dialogs, Wizards

SWT

e.g Buttons, Trees, Lists, Tables
