With this driver you can access the files created by sqlite3 through the standard TQt sql module. The driver name is QSQLITE3. Although there are many other solutions to access such DB files, I think that using this driver has some advantages: --> You use the standard TQt interface so you can reuse exinting code or switch to or from other DB types quite easily. --> The source of this driver is smaller than any other, you can incorporate it on your application with little overhead and without requiring external libraries. Developer note: The driver is a merge between the QSQLITE driver in Qt 3 and in Qt 4 beta 1, with small tweaks, so I think is quite stable and usable. Please report success or failure, thanks To compile qmake make cp sqldrivers/libqsqlite3.so $TQTDIR/plugins/sqldrivers (probably as root) use it as any other TQt sql driver. Have fun, Stefano !!!
