Re: [wxperl-users] Threading in wxPerl

[Mike S. <Mik...@Do...>]

We use POE instead -- not threading, but a lot easier for cross-platform 
work.

http://search.cpan.org/~mike/POE-Loop-Wx-0.03/

There are some examples there too.  While you can put each frame in its 
own POE session, our approach now is to have one POE session for Wx, and 
any other POE sessions as required.

Also, we are almost ready to release Wx::Data -- a collection of modules 
that uses Wx and POE to create data-aware Wx controls that can talk 
asynchronously back to a POE-based server -- letting the the client use 
POE and the server.  This way a complex frame with multiple controls -- 
each control can asynchronously connect back to the server (with common 
cache keys in the client and the server) and populate themselves 
independently.  We are just finishing up a REST-like cachekey / data 
access that is shared between the controls and the server to allow for 
distributed caching of data and server-push updates of cache data to the 
clients.  Once that is all done, we'll be doing an initial release to CPAN.

Anyhow, all that to say, you may want to consider POE as an alternative 
to threads.

Hope that helps.

Mike.
