Architecture/Process Flow

Startup- and Shutdown sequence of OpenOffice.org

1. Construction of the global application object
2. main() method of the executable
3. Initialization of the VCL library
4. Initialization of the application object
5. Bootstrap initial UNO component context
6. Sets global process service factory
7. Creates Office configuration service
8. Determines the current Office language and initialize language settings for Office configuration service.
9. Creates IPC thread and named pipe for office-office communication
10. Sets exception handler
11. Calls Main() method on application object
12. Handles bootstrap errors (show possible bootstrap errors to user and exit application)
13. Creates and show splash screen
14. Creates user configuration data on first startup
15. Checks command line arguments and creates possible UNO acceptors
16. Initialization of the UCB
17. Creates global temporary directory for Office
18. Sets user interface and application locale
19. Creates global broadcaster service for application/document events
20. Starts first start wizard for possible license agreement/user data input
21. If no command line arguments
    1. Creates one instance framework desktop service
    2. Creates startup module service
    3. Creates frame and connects startup module to frame.
22. Checks command line arguments and creates possible quickstart service
23. Checks command line arguments for headless mode and if positive activates internal dialogs
24. Starts the global application message loop
25. Asynchronous (default) document creation/loading.
    1. Analyzes the command line arguments and determines a possible default document type.
    2. Loads/prints documents provided by command line
    3. Shows the document window(s)
    4. Enables the IPC thread to receive data from the named pipe.
26. Asynchronous enabling of the UNO acceptors
27. Office shutdown triggered by: Terminate call on the com.sun.star.frame.XDesktop interface or Menubar “File – Exit” or keyboard shortcut “CTRL-Q”
28. Closes all open documents (asks for allowance for modified documents)
29. IPC thread blocks all requests from other Offices
30. Removes the global temporary directory
31. Stops all UNO acceptors
32. De-initializes UCB
33. De-initializes VCL library
34. De-initializes global application object
35. Stores all Office configuration changes
36. Disposes default UNO component context
37. Disables IPC thread for office-office communication
38. Leaves main() method
39. Destroys global application object
