Re: [Discuss-gnuradio] python Hier block using callback

[Marcus Müller]

Hi Themba,

the interesting point here is where you register your callback. You say
you've included the callback in the .grc file; if that's the case, you
should find it searching for the name of the variable you change using a
slider etc in the python file GRC generates.

Greetings,
Marcus
