Which DBI driver are you using ? (e.g., DBD::ODBC, DBD::mysql, DBD::Pg, etc.)

Which version of Perl/TK are you using ?

Alas, most DBD's have no async i/f, so such things are difficult to handle, esp. given both DBI's and Perl/Tk's less than robust threading implementations.

(Hopefully I'll one day get Thread::Apartment and Perl/TK running together - once I figure out how to handle closures - , and many of these issues will hopefully go away, esp. in combo w/ DBIx::Threaded. The latter may help provide a solution, esp. the async methods (see $sth->start_execute()), tho I haven't yet tried to get pTk and DBIx::Threaded to play nice together - which I'll be needing to do soon as well).

In the near term, you might try running Perl/Tk in its own thread, open a Thread::Queue, and use Storable to transer result data (not the handle, the actual data) to pTk. Then set an after()/repeat() in pTk to poll the queue.
