Re: Going from GUI to non-GUI operation.

[Nate Temple]

Hi Glen,

One other possible approach could be to separate your processing flowgraph from the display/GUI flowgraph. This could be done with a combo of ZMQ blocks, the Parameter block and XMLRPC blocks.

Depending on your data rates, this might not work so great and is a bit wasteful of CPU cycles.

There is a "disable" function in GRC -- so the scaffolding for the block
is there, but not actually enabled in code generation.

Unfortunately, there's no GRC-way to do this at runtime.

You can then run your python file directly, or even call the created class object from another file (have a look inside the main function to see how the flow is instantiated). You can also get and set variable values in runtime via Python and have the flow update, just like you can with the GUI.
