RE: [wxperl-users] Request for Wx::Data Namespace

[Donovan A. <al...@Zo...>]

FYI, so you know there is interest, I would be keen on playing with the =
PAR component and any POE::Loop::Wx improvements that may have happened. =
=20

I am using Wx, POE+POE::Loop::Wx, Win32::OLE, XML-RPC & YAML based RPC =
system, among a billion other things to build a centralized exhibit =
multimedia logic & control system, including (Digital/Analog I/O, =
projectors, audio mixers, & DMX In/Out among other hardware interface =
things), media playback (and asset management), content "programming", =
"program" schedules...yadda yadda yadda.

At this time, it is Win32 on the front end (the multimedia stuff) and =
linux on the backend.  Some of the components are designed to run on =
either platform, some are not.  I have a poor man's rsyncd system to =
update the system everyday, but I have to tread carefully with this =
brute force method ...so the PAR bit would be neat to see.

Subject: [wxperl-users] Request for Wx::Data Namespace


A little history first...

Our company (DonorWare) has been creating a WxPerl front-end to our
business logic for the past year and a half.  Now we are wanting to
refactor our code and provide the application framework back to the
Perl community.  Also, a while back I sent an email to this list for
WxPerl contractors and got some immediate responses -- thank you!  One
of those contractors (Brad Embree) has been working on Dynamic Panels
and Dynamic controls to allow an application to build itself dynamically
off of metadata received from data calls.  The other contractor (Eriam
Schaffter) is about to start on the refactoring project for making Wx
frames and controls "data-aware" using POE as the backend event loop.
By the way -- this all works in Win32, Linux and OS X.   Again, my
thanks to Mattia for his help getting the POE::Loop::Wx module working
last year.

All that to say....

We would like to use the Wx::Data namespace for this "data-aware"
POE framework for WxPerl.  Here are some examples of what will be done:

Wx::Data::Manager -- spawns a POE session to manage data
publish/subscribe events between data sources and Wx frames/controls
that consume those data sources.

Wx::Data::Client::HTTP -- spawns a POE session to asynchronously manage
requests to HTTP-based data sources.  This is our first one, but we
could see the addition of Wx::Data::Manager::SOAP,
Wx::Data::Manager::DBI, etc.  In this HTTP version we use
Data::Serializer to manage serialization, encryption, compression, etc.

Wx::Data::Server::HTTP -- used on the server side to create a daemon to
respond to requests from Wx::Data::Client::HTTP.  This allows you to use
your existing business logic modules (or write new ones) that can be
used by the controls in your WxPerl app.

Wx::Data::Control -- a namespace for creating data-aware controls that
can automatically subscribe their data needs to the Wx::Data::Manager,
and automatically receive the responses to populate the control.  For
example, Wx::Data::Control::CodeChoice would make adding a Wx::Choice
control that populates itself off of a code table back on your server
very simple and trivial.

We also have a framework using PAR that requires a minimal binary
launcher for the operating system you are running on that then fetches
Pure Perl WxPerl code that can be run cross-platform.  This allows you
to make central updates to your application and your users get a fresh
version of your application code each time they login.  We could also
look at refactoring this and adding to CPAN if anyone is interested.

That gives you an idea of how we would like to use the Wx::Data
namespace.  This is all working already in our existing
namespace/application, but we wanted to make sure this direction would
be acceptable before refactoring into a CPAN module/bundle.

Mattia -- is Wx::Data acceptable to you?

Thanks in advance to any feedback or suggestions.

Mike.
