int set_pin_FLOAT_calc(float, QString) sig velControl is not writable or not e

Based on these old .h file, try to write some pin .... but seems after upgrade to Lcnc2.10pre0 ... it not work properly ....in 2.9 all work perfect, in 2.10 pin not exist or not writable .... someone can send me in right direction?

in attach my heather (sorry for lot of comment, but was "original"):
 

int set_pin_FLOAT_calc(float, QString) ... these function connect all pin to qt gui ... and receive some error ..
 

Did you get to the bottom of this? I just tried searching the code and did not find any instances of the function name, even in 2.9.

Maybe it is part of an external library? (QTPyVCP maybe?)

is mine ... c/c++ qt .... but for sure other here use a quite similar code .... any how problem is solved .... unfortunately nor remember how and why ... but now code work .... think linking lcnc .a lib.
