I'm trying to use a callback to set a variable in an embedded python block.  Using the tutorial (https://wiki.gnuradio.org/index.php/Embedded_Python_Block <https://wiki.gnuradio.org/index.php/Embedded_Python_Block>) as an example I added the function below.  I've found that this callback never gets called when I update this value from a GUI.  Should it be?

|def set_example_param(self, example_param): print("here")|

Hi Jameson,



self.foo = foo





Best,
Daniel.

I think Embedded Python blocks can only have (automatically generated) callbacks for __init__() arguments that are assigned as in the body of __init__() (the example template that you get when you create a new Embedded Python block shows how this works). If you need more complex callbacks, I think you need to create a regular Python block in an OOT module.
