c2248 and c2512 errors in the compilation of the MAPX component after the QT environment has been packaged

c:\qt\qt5.6.0\5.6\msvc2013\include\qtcore\qmetatype.h:760:error:c2248: "Mapspace::irowcursor::irowcursor": Cannot access Private member (declared in the "Mapspace::irowcursor" Class)

c:\qt\qt5.6.0\5.6\msvc2013\include\qtcore\qmetatype.h:761:error:c2512: "Mapspace::irowcursor": no appropriate default constructor available

On the internet for most of the days have not found a solution, as if suddenly saw someone said can look at the source code.

I went in and looked at the source, and found out where the problem is, as shown here.

Can see: New when the error, and then according to the wrong prompt class, you re-write the class's copy construction and default construction, the original private macro comments out, compiled through.

Then called the method of Mapx to try it, the successful popup "about" window.
