Hi,
I have a simple flowgraph comprised of two channels (UHD: USRP Source) connected to two separate Qt GUI Waterfall sinks.
This works perfectly in Python/GRC. However, I would like to convert this into C++.
Previously,
I did conversions successfully for various other flow-graphs without
GUIs. However, in this case, although the 'exe' file compiles fine and
it runs fine without any errors, I can't get it to display the Waterfall
plot.
In my current C++ code, the UHD Source Block
and the Waterfall Sink block are constructed, set-up and properly
connected to each other. I thought this will automatically allow the
Waterfall graph to display but it doesn't.
Following the python code in [1], I tried in my C++ code the following line,
[1]
http://gnuradio.squarespace.com/examples/tag/qtguiQApplication app(argc, argv);
I
am not expert in Qt, but I think this is a constructor call that
creates an QApplication instance to process the Waterfall data, right? Can you please give me a hint on how
should I go about handling/displaying the Waterfall data from there?
Thanks in advance for your help.
Regards,
khalid
