Re: Dynamic variables in C++ OOT for Gnu Radio 3.10

Hi Huang Wei,

nice to have you here!

Can you show us where you use `_param` in your C++ implementation?
What you show us looks right, in general.

Best regards,
Marcus

And I have added in the .yml file:
callbacks:
- set_param(${param})

But still the value can't be changed.

    Hello everyone,

    In Gnu Radio 3.10, how to set a variable in a C++ OOT block that can be 
adjusted
    dynamically by a QT GUI range?
    I did in a .h file:
       Private:
         float _param;
       Public:
         void set_param(float param) {_param = param;}
    and in the impl.cc file:
       _param = param;

    anywhere else I need to change? I just tried before in Gnu Radio 3.7, and 
now I am
    very lost with the new version.

    Thank you very much.

    Regards,
    Wei
