Hi list, FYI, I went through the documentation and I managed to get it to work :) All what I need to do was to define a layout so that the waterfall widget can be added to it.

To: "Discuss-gnuradio@gnu.org" <discuss-gnuradio@gnu.org> 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/qtgui QApplication 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
