arsinte_andrei

Dear friends,
I'm trying to create an instance of a class into the main.cpp but without success.
here you have some piece of my code

main.cpp
@
atpGuiMainWindow win = new atpGuiMainWindow;
vin->show();
@
give error
/home/andrei/Qt5.3.0/5.3/gcc_64/include/QtWidgets/qmainwindow.h:204: error: 'QMainWindow::QMainWindow(const QMainWindow&)' is private
Q_DISABLE_COPY(QMainWindow)
^

now I find anther aproch but this time not so much changed...
@
typedef atpGuiMainWindow(*MainWindowHandler)();
MainWindowHandler win = (MainWindowHandler());

@
but this dows not allow for
@win->shhow();@
/home/andrei/myQt/drawElectricity/main/main.cpp:72: error: request for member 'show' in '* win', which is of non-class type 'atpGuiMainWindow()'
win->show();
^
without this the code is working - but no gui :))
operation succesfull - client dead :))
any help much apreciated
please note that the atpGuiMainWindow is in a library and I call it from library
