Re: Making C++ OOT module and wish to set up a parameter with different choices!

[Ron Economos]

It's done in the .yml file in gr-foo/grc. Here's a simple example:

https://github.com/gnuradio/gnuradio/blob/master/gr-analog/grc/analog_sig_source_x.block.yml#L6

And a more complex example:

https://github.com/gnuradio/gnuradio/blob/master/gr-dtv/grc/dtv_dvb_ldpc_bb.block.yml

If you use a definition from an additional project .h file, that .h file 
must be included in gr-foo/swig/foo_swig.i.
