Hi,
And using a QT GUI Chooser with type "Any" and using its entry to configure the other blocks?

Thanks for your answer Ron!
Unfortunately no, we plan to play with blocks in the GUI and so no Python script or C++ code, at least at the beginning... :(

I'm not sure if this fits your requirements, but you can use a stand alone Python script. Here's an example for the DVB-T transmitter.

Hi everybody,

I am creating a small design (similar to the DVB-T one included in gnuradio-dtv) and I wanted to set some parameters once (at design and *not* at execution time) with a combo box (to limit the possible choices to valid values only). For instance, if we consider the above mentioned DVB-T design, one might want to set the chosen constellation just once and not for every single block that needs that parameter. Is there an easy way to achieve this result?
Thanks a lot in advance and have a nice day!

Rob
