[Qt-interest] Error in defining a static data member to a class

[Akshey Jawa]

Thanks a lot. The in-class definition gave a compilation error. But the
defining in .cpp file worked!
Is it some problem with Qt or the same applies to other compilers too ? I am
not an experienced programmer.

Thanks,
Akshey
