I am trying to create a progress bar for my class member function when it runs, but when I pass an array of strings and an array of bools into the QTConcurren::run function I get this error:
Error C2075 'QtConcurrent::VoidStoredMemberFunctionPointerCall4::arg1': array initialization requires a brace-enclosed initializer list.
My class is called CreateInputFiles, and the object of that class is called inpFileObj.
I tried adding & in front of the name of the array, but I got yet another error.
