We are pleased to announce Dabo 0.2, the second major release of our
data application framework. The Dabo framework is a true 3-tier design,
with data access and UI code separated from your business logic. And
since it's Python, and uses wxPython for its UI, it is completely
cross-platform, having been tested on Linux, Windows and OS X.

The new prerequisites are:
wxPython 22.214.171.124 or later
We are encouraged by the response we've gotten so far from our earlier
releases - there certainly seems to be a lot of interest in creating
cross-platform data-intensive apps! We are continuing to move forward,
and encourage anyone who is interested to join our mailing lists:
dabo-users: for those interested in learning how to work with Dabo to
dabo-dev: for those interested in the ongoing development of Dabo
Here is a brief summary of what's new in Dabo 0.2:
Dabo now works with FireBird as well as MySQL databases. We've begun to
add support for SQLite and PostgreSQL, but they won't be ready until
Database connection info is now saved with the passwords encrypted.
Abstracted out the wxPython event model, greatly simplifying the
binding and raising of events, as well as the definition of new events
Improved unicode support.
Code for Dabo applications has gotten more Dabo-like, and less wx-like,
as Dabo has abstracted the UI much better. For example, it is not as
necessary to add an 'import wx' statement in your code anymore.
Added logger objects to send program output to, instead of directly to
Began abstraction of Tkinter at purely an experimental level.
Added some new controls, such as a better date control and a combo box.
We've created a new wizard for generating basic Dabo applications.
Check it out at http://dabodev.com/wiki/AppWizard .
The generated apps now save their configuration in standard XML files.
There is a new visual editor for modifying these files and previewing
your changes. See http://dabodev.com/wiki/FieldSpecEditor for more
While Dabo is primarily aimed at creating database apps, it works great
for apps that don't work with data, too. To illustrate this, there is
now a game called 'Bubblet' included in the demo that is written in
Dabo but doesn't connect to data.
Added a Python code editor and dubbed it 'dEditor', located in the
'daboIDE' directory. This editor, based on Scintilla, features
everything you'd expect: syntax coloring, auto-indent, zooming, line
numbering, call tips, and auto-complete. It represents the beginning of
an effort to bring a simple multi-platform IDE to Dabo, which will be a
central place to work on Dabo-based projects. A project manager, a good
set of editors (code, field specs, database definitions, report
layouts, UI layouts, etc.), an interpreter, a debugger, and quick links
to documentation will all be provided. It's a major undertaking; this
is the first step in that direction.
