Hi, from designer I've created a connect from a pushbutton to a SLOT: i've included <qdateandtime.h>; nmake clean; qmake;nmake; but this eror occurs.Why?
this is declared in designer: setTime(const QTime &)

Code:

Shouldn't it be "#include <qdatetime.h>"?

sorry, I've write it wrong only here... I've just insert it in implementation (from designer)
"qdatetime.h".......

Could you show us the header file that uic produced from your ui?

Have you implemented the MainForm::setTime( QTime const & ) method?

I don't why, but designer didn't insert slot in mainform! I deleted connect and re-connect...now it's works. Thanks
