Re: Custom Qt GUI Sink Block

[Barry Duggan]

Jerrid,

If you want to display text messages, take a look at 
https://github.com/duggabe/gr-webserver

You can send your text to a ZMQ PUSH Message Sink and it will be 
displayed on the screen. There should be very little load on your system.

Let me know if you have any questions about it.

Hello Volker,

I have tried using gr-display, however I am working with GNURadio 3.8 
and not 3.9, which I am guessing is causing some difference in the way 
the gr-display sinks work. The way the text sink works in 3.8 is not 
ideal as it more or less replicates the debug box from GNURadio 
Companion into the GUI, which strains my system and causes a lot of 
underflow. Ideally I want to make a sink block that is just like the Qt 
GUI Number Sink block, but instead of taking in floats it takes in 
pmt's, and I want to be able to do that in python as my skills in C++ 
are lacking. This also makes it hard to try and understand the code 
written for these blocks to then try and adapt to what I want to do in 
python. Any help or suggestions regarding a python solution to creating 
custom Qt GUI Sink blocks would be greatly appreciated.

Best Regards,

Jerrid
