Hello!
I've seen some messages reagrding Qt and GNU Radio, and some code in
the repository. I'd like to use Qt and QWT. QWT simply looks great and
very useful, and I hope to get better performance with Qt compared to Wx.
AFICS the graphical sinks need some way to get the data from a block.
Other parts like buttons, check boxes, boxes, labels etc. do not need
to interact with GNU Radio flowgraph data (only things like set
parameters, reconnect, all kind of 'meta'-manipulation). So I assume
one (simply ;-) ) needs to write the glue code for the sinks to get
real use of Qt.
I guess I'm not the first one thinking about Qt, but I could not find
any rationals for or against. Any ideas, pitfalls/caveats, experiences?
I am really having a problem right now getting Qt 4.3.X to successfully
compile Qwt under F8 x86_64. I agree with your assessment that it is
efficacious for us. I just do not have all the time I would like to
work through this for some time to come. The first task I set for
myself was to take the new hier block 2 version now that it has
stablizied and to use the FM stereo receiver as my first example. I was
going to use the Qwt radio example to build this radio. I also wanted
to add the nascent RDS code to it so we could get that going as well.
I am uninterested in using Qt 3 for all sorts of reasons. After this
example I was going to take what I did and apply it to building a
serious signal processing tool using GnuRadio and tools we are adding to
GnuRadio at work in a package that would eventually "sweep" SkySweep
capabilities into GnuRadio. I think as a group, we can exceed the
capabilities of SkySweep and make all of this capability available in an
open source version using GnuRadio as a truly killer app. The timing of
this was pushed on me (FINALLY) by work beginning on multithreading or
use of serious concurrency so as to take full advantage of the
parallelism available on almost everyone's desktop these days.

What I need is ten more hours in each day. My peer on this and I are
just buried up to our necks at work and I would really love it if you
took this forward and made a start.
