releases BlackAdder is pleased to announce the release of its Windows/Linux GUI development environment for Python, BlackAdder. BlackAdder combines a visual design environment with debugging, syntax highlighting, ODBC interfaces and extensive HTML documentation into a comprehensive platform for developing Python applications. Update: 01/14 10:50 AM by wes: The press release has been updated with corrections from Shawn Gordon.

We worked with Trolltech, the creators of the Qt windowing toolkit on which BlackAdder is based, and eGenix, creators of the multi-platform ODBC interfaces for Python known as mxODBC, and were able to derive a license arrangement to bring the most power and flexibility to BlackAdder.

What is especially exciting that BlackAdder not only runs on Linux and Windows, it generates applications that will run on either system as well. This protects your investment in development by enabling you to develop and deploy your applications almost anywhere. Unlike similar products, BlackAdder includes all the elements needed for developing complete applications and the rights to re-distribute the necessary run-time elements, highlights of the BlackAdder are:

  • Organizes your Python scripts and GUI designs into easy to manage projects.
  • An editor that includes highlighting of Python keywords and code folding.
  • An interactive Python interpreter (v2.0) that allows you to execute any Python commands while your application is running.
  • A license to access the Qt GUI toolkit API (v2.2.3) from Trolltech
    via the PyQt Python bindings only.
  • Qt Designer from Trolltech with a modified user interface compiler
    that generates Python code.
  • A debugger that supports single stepping and
  • ODBC database connectivity (using mxODBC v2.0 from eGenix).
  • Over 50Mbytes of HTML documentation.

BlackAdder is available in two editions, "Personal" aimed more at the home hobbyist and "Business", both editions produce the same high quality, professional applications the only restriction is the ability to create proprietary applications for resell.

I'll be frank: if I develop a GPL app I would only be interested in a Linux version, forget Windoze, it doesn't deserve my time, IMO.
If I'm doing a commercial app, then I would do both, 'cause that's where the $$$ is. Obviously, in that case I can affort to buy BlackAdder Business Edition.
