mainwindow.h or detwin.h doesn't see <memory> header

[BartoszT]

I have base class mainwidow and another window's class detwin.
mainwindow.h includes <memory> header
mainwindow.cpp includes mainwindow.h . mainwindow.cpp file sees shared_ptr
but inside mainwindow.h and detwin.h I cant use shared_ptr

what's going on with QT?

@BartoszT This comes from code model I guess?
Does your app build?

shared_ptr is in the namespace std.
This should do the job

std::shared_ptr<DaneKlasaBazowa> ptr
