Hi, This is to announce a new tool for rapid prototyping of data-driven applications: DWI/DUI (Data With Interaction / Data Under the Interface). One uses it to hook up a GUI created with Glade to an SQL database. Version 0.1: it works fine, but I don't yet know if one can create more than a toy application with it at this point. But I think its interesting; after all, I wrote it :-) http://www.linas.org/linux/dwi/ --linas DUI -- Data Under the Interface (aka DWI -- Data With Interaction) ---------------------------------- This is a rather basic (simplistic, even) environment for quickly creating data-driven applications, that is, graphical applications that manipulate and show info from a database. This environment differs from others in that it is focused on native GTK/Gnome support through the Glade GUI designer, and thus allows you to build user interfaces as elegant as you can make them in Glade. At this point, this system is not terribly feature-rich, but it should be adequate for creating basic form-editing and reporting applications. Multiple SQL databases are supported through an ODBC driver. It should not be hard to add a native Postgres driver, or even a non-SQL database driver. The actual connection between the database fields and the glade widgets is described in an XML-based "DWI" file. Currently, the only way to create DWI files is by hand. In the future, we hope to have an extension to Glade, or possibly an extension to a database-browsing tool that will allow you to graphically make such connections. Note that the design of the XML format is sufficiently generic that it is not directly tied to Glade. It is envisioned that it could be used to create data-driven web pages. That is, Glade is currently the only GUI driver, but other drivers for other GUI's should be possible. ================================== A basic example, with more-or-less complete documentation, can be found in the "testbasic.dui" example. This file describes the database-to-interface coupling is in an XML format. It can be run with the "dwi-run" interpreter: $ ./dwi-run testbasic.dui Note, however, you will need to setup the database first. If you're using Postgres, then run the following Postgres commands: createdb bogus cat testbasic.sql |psql bogus You will also need to setup odbc to access this database.
