- #19 File System Sender writes to a file Receiver reads from it But when does the receiver do the read? Often synchronized with file locking or lock files Special types of files can make file-based IPC easierMessage-Based IPC Sender formats data into a formal message With some form of address for receiver OS delivers message to receiver’s message input queue (might signal too) Receiver (when ready) reads a message from the queue Sender might or might not blockProcedure Call IPCInterprocess communication uses same procedure call interface as intraprocess Data passed as parameters Information returned via return values Complicated since destination procedure is in a different address space Generally, calling procedure blocks till call returnsShared Memory IPC Different processes share a common piece of memory Either physically or virtually Communications via normal reads/writes May need semaphores or locks In or associated with the shared memory
- #22 AppBuilder: show, hide, delete : proxies for IDE viewgetViewHwnd: get window handlesetEmbeddedWindow: Sets the given view as the parent for the given windowHandleaddWindow: With this API multiple windows can be attached to a view. (add palette and )
- #23 Description:1. A .w file can be opened from the IDE by double-clicking the file in the Project Explorer view, or by dragging the file from the the Project Explorer view onto the AppBuilder window. Alternatively, a .w file can be opened from theAppBuilder. In either case, the openLinkedEditor method is called in the IDE to link an OEIDE Editor instance to the AppBuilder. The actual file is opened in the editor and a copy via a temporary file, is opened in the AppBuilder. The editor and the AppBuilder have the same content.2. Using the Edit Code option (Section Editor) in the AppBuilder causes the AppBuilder to synchronize the changes to the temporary file (syncFromAB), and then it invokes the selectSection method to reposition the code to the trigger section for the selected widget. If there are no triggers defined for the selected widget, a default trigger is created when synchronizing. The editor gets updated from the AppBuilder.3. Any of the AppBuilder dialogs and windows can be used to modify the instance of the .w file in the AppBuilder.4. When the OEIDE Editor gets focus, the syncFromAB method is called in the AppBuilder to synchronize the file. The editor gets updated from the AppBuilder.5. Any of the OEIDE functionality, in particular templates, can be used to modify the instance of the .w file in the OEIDE Editor.6. When the editor loses focus, the syncFromIDE method is called in the AppBuilder to synchronize the file. The AppBuilder gets updated from the OEIDE Editor.7. When the file is saved in the IDE, the syncFromAB method is called in the AppBuilder to synchronize the file. The editor gets updated from the AppBuilder.8. When the file is saved in the AppBuilder, the file is synchronized (syncFromAB), and then the saveLinkedEditor method is used to save the file on the IDE side. The editor and the AppBuilder have the same content.9. When the file is closed in the AppBuilder, the unlinkEditor method is called in the IDE so the editor does not try to synchronize with the AppBuilder.10. When the file is closed in the IDE, the instance of the .w file in the AppBuilder is closed.
