Hello, I've got hold of a barcode laser scanner and started to write a tool to scan my large DVD, book and comic collection. It's written in Python and PyQt4. The announcement can be found in my blog:
http://darkviews.blogspot.com/2008/10/upcscan-06-its-qt-man.html If you're looking for an example how to implement a live UI, this might be for you. A list of features: - A Pythonic(tm) table model. The model is based on a Python list. The list contains Python objects and the model translates the columns into attribute accesses. The most important missing feature is that the model doesn't listen to list modifications. - The model uses a proxy for sorting and filtering (the latter is not implemented ATM). - I'm saving all changes in the UI into a sqlite3 database which runs in a background thread. When you type faster than the DB can write the changes to disk, requests will be merged (if you send a second request to the database to update the same thing, the first request will be canceled). This makes the UI responsive while it's still not possible to lose even a single keystroke when the computer crashes (unless the filesystem is corrupt afterwards :) - It shows how to save and retrieve binary data (cover images) to/from an sqlite3 database and how to convert the bytes into QImage, QPixmap and QIcon. - It demonstrates how to write a script which runs in console-only-mode if PyQt4 is not installed. - The database is versioned and there is code to migrate the database from version to version. Feedback welcome :) Let me know if you're interested to put this code somewhere as an example (a PyQt book, a wiki, whatever). Regards, -- Aaron "Optimizer" Digulla a.k.a.
