Hi Steffen,
You're missing that the embedded Python Block should work just like any
other block. If you want to read a button state or accept a message then
you'll need to add a parameter to the Python block and pass in the
button's ID (variable) to it or add a message port to the block.
The Embedded Python Block tutorial does a good job covering the message
side and adding a parameter is part of the default Python Block template.

As a related note, in the very latest maint-3.8 and master codebases
there are now Python Snippets for injecting Python code directly into
the generated program. It's useful for a variety of situations, but the
ones you're describing here are already usually handled well by the
existing features.
Cheers,
Derek

Hello!
I am new to using GNU radio, and i would like to implement some custom
features.
I would like to access functions like the get_push_button to read its
state, or read a message box etc.
Is this even possible from the epy block?
I could also implement this directly in the top_block.py file, but my
problem is that if i want to change something in the GUI, this file is
overwritten, and the custom code will be erased. Or am i missing
something?
