Simply Powerful ToolKit 3.0.11

Simply Powerful ToolKit in short SPTK is a powerful widget toolkit based on the Fast and Light ToolKit (FLTK).
The goal of this library is to create the easy-to-use, compact and effective library of controls to extend the abilities of FLTK library.
It is geared for business-style application development with database support (ODBC). All the widgets support database connectivity. A special CDialog class makes editing database records very easy. Every widget can be connected to the field, and CDialog can be connected to the database table.
Most of the controls are database-bound. If you place them on the CDialog-derived window they can load and save information from/to database.
This is the first release version of my controls(widgets) library that was designed to work with FLTK. Im using it for about a year in the production project.
Enhancements:
- Fixed a bug in CField::asString() that cause returning an empty string for some non-empty fields.
- Added couple of small fixes for better error hanling in CRegistry.
