Database-aware slider widget

Today something more lightweight than usually.

New database form widget has arrived: slider has been developed for Kexi, as a tutorial for the polish edition of Software Developer's Journal. The widget is usable when data is restricted to a given interval, and in the tutoral it is provided witin a custom widget factory (i.e. an extension, plugin) to show how to implement such thing and let Kexi find it.

The article also contains second tutorial: "How to implement a command-line app for exporting table or query data to Fixed-Width Text format in 'a few' lines of code". No single backend-dependent line of code is included, so you can export from SQLite, MySQL and PostgreSQL so far.

The source code will be probably included in Kexi 2.0. I plan to "open" the tutorial and translate it to english as soon as the publisher allows that.
