Hi Cesar, I don't know why your embed does not work, but I would suggest to rework your code a bit and follow the pattern used by Dirk in his Qt example:
1. create an RInside instance "R" in the "main" function 2. pass that RInside instance by reference to the constructor for MyEvaluator and save it to a private member variable 3. MyEvaluator::eval_x can work the same as now, except that it will begin at the line "R.parseEvalQ" since you already have the RInside instance Hope this helps, Davor On 2011-03-18, at 7:49 AM, CESAR PERNALETE wrote: > > Hi Davor. > > Thanks for your response.
