Fortuitously, the topic came up this week about which languages/toolkits
have served us best for network-related software development. On that
vein, I'd like to share an experience I had yesterday with Qt's network
I've always liked Qt's network library. I've watched it mature over the
last few years, and have been generally impressed. It's all non-blocking
by deafult, so your app will stay responsive. It's got a clean API that
lets you get to work on your problem without lots of network-related
Yesterday I decided to add SSL support to a network app, the server and
client side of which I wrote in Qt. It's XML-RPC for the record. I was
amazed at how easy it was. Using Qt 4.3.2's QSslSocket and its new
SSL-enabled QHttp classes, it took about 2 hours. That includes allowing
the user to specify their own key/cert files on the server side. I had
never worked with SSL before, so I was very pleased at the development
Previously, I added "deflate" compression support to the same app, using
Qt's qCompress() and qUncompress(). Worked great, and it's standard HTTP
(my client can interact with Python's XML-RPC server as well). That only
took about an hour to do.
All told, I'm sold on Qt.
Just my $0.02 in case anyone wanted to know.
