Re: [Discuss-gnuradio] WX GUI Widgets Under C++

[Daniel Labarowski]

Josh,
Thanks for the reply. The QT Gui Time Sink sounds like it might be similar to the scope and the Sink sounds like it might be an fft, but I can't seem to get them to run in GRC. I am receiving the error below. It looks like these blocks make a call to top layout which doesn't exist? I built gnuradio using the build-gnuradio script on the 25th of last month.

The existing WX widgets and windows in gnuradio are exclusively python.
You would have to involve python in your application to use them.

Now, the QTGui widgets, those are written and can be used in C++
