Re: Improving GRC usability: How do you deal with changes in .grc file behaviour caused by opening it on newer/older GRC version?

2022-03-07 Thread Bernard Tyers - EI8FDB
Hi there, I'd like to say thanks to the community members who've contributed to this issue so far, and make another request for anyone interested in giving their input. Has this scenario ever happened to you - You open a .grc file with an older (or newer) version of GRC than the file was

QA Tests: Python vs C++

2022-03-07 Thread Jeff S
I started writing some QA tests which were missing for some blocks I'm working on (in maint-3.9). I decided to compare using Python vs using C++ when building new tests. When I started looking into the C++ tests, it seems that there are not a lot of examples around, so I started wondering why

Re: QA Tests: Python vs C++

2022-03-07 Thread Josh Morman
Jeff, When tests are done in C++, they also must be compiled, which adds to the overall gnuradio compilation time. In-tree the c++ tests are reserved mainly for testing the really low level like buffers. I agree with you that an all c++ target makes debugging easy, but you can launch the python

Re: Selecting a SDR as a sink

2022-03-07 Thread Josh Morman
David, There are a couple of problems with using the selector in this configuration. 1) If you plan to just disable the sinks in GRC, then you don't need the selector at all. That block is intended to be used to change the configuration during runtime. You can just connect all the sinks to the

Hi Jeff, since all the data handling is done in C++ land in GNU Radio anyways, the only difference in test performance is when the Python code takes longer to evaluate the the result of some flow graph. For example: if you write a test case where the data from a vector sink is compared to

Re: GRC 3.9.4.0 - module porting problem

2022-03-07 Thread David Taylor (manx.net)
Hi Ryan, I eventually managed to port the working GRC code from 3.8.2.0 to 3.9.4.0 by rebuilding the GRC with pybind11 2.5.0 installed and having replaced version 2.4.3, for all binding operations. pygxxxml 2.2.1 was also retained. The porting guide document after re-read is entirely correct

GRC: is it possible to show grid

Dear All, Is there a way to display the grid (to which blocks get locked) on the canvas? If not, any tips on how to implement it? Thanks. M.Patil

There is no option for that AFAIK. To implement it, you'll want to start here: https://github.com/gnuradio/gnuradio/blob/main/grc/gui/DrawingArea.py#L213 The grid size is defined in https://github.com/gnuradio/gnuradio/blob/main/grc/gui/Constants.py#L50 Best add a color in

Re: GRC: is it possible to show grid

Thank you. This will be helpful. I was trying to see if Gtk allows grid drawing with a single command, but I could not find that. In that case, I guess I have to do two loops: one for horizontal lines (using move_to/line_to) and one for vertical lines. If there is a better way, please let me
