Working on the UI for my MP3 stereo component.
Tiny C program to read the IR receiver.
Perl/Qt 3.0 for the UI... but QThread isn't available in the Perl bindings, and I can't seem to find a way to add a new item to wait on to the main loop's select, except a socket descriptor.
So, have a perl wrapper around Tiny C program that makes C program's output (IR codes received) available over a TCP socket.
Then I'll use a QSocket (hope it's implemented in Perl/Qt!) and a QSocketNotifier to give the Qt main loop an event when a new IR code is available.
If I get this working, then I'll clean it up, either moving to Perl 5.8 threads, or rewriting the C bit in Perl, or writing the Perl network wrapper in C. Or maybe I'll just get it working and be happy, even with 3 processes running to do it.
Qt is pretty cool ... the Perl bindings are a little non-Perl-like, but not bad. Learning the Qt API is taking the most time.
Update: QSocket appears to work. QSocketNofier doesn't. Grrr. Back to square one. Use a QTimer to regularly poll the socket to see if there's anything there? Lame. I guess this is what I get for using just-released bindings.
I could just do this all in C++ I guess. Feh.
