Class Definition Consistency

In preparing to create the recreator class, I noticed that all the class definitions were not consistent - some had the private members at the beginning and some had them at the end.  Having the member functions at the beginning allow access functions for instance to use them, at least this was the case with early C++ compilers (or at least was my understanding when learning C++ over two decades ago).  But this does not appear to be a requirement with modern compilers.

It appears the Qt developers like to put the private member variables at the end of the class.  The public function definitions start at the beginning followed by the private section, which start with the private function definitions.  So, before embarking on creating of the recreate class definition, the non-conforming classes were changed to this style.
