[Discuss-gnuradio] question developing a new block

[Andreas Ladanyi]

Hi,

i read some tutorials about creating new blocks.

Iam asking my self a simple question and i think i couldnt find the answer:

How is it possible to fill a python grc variable block with data from 
another block C++ variable.

I know between C++ and python is the SWIG Framework. What to program in 
the C++ file and what to program in the xml file.  The way of the C++ 
variable through the swig to the python workflow is not clear to me.

I know that the grc editor creates a variable section from variables of 
all grc blocks in the workflow in the project .py file.
