What do I do wrong

wysote,

I use vs2008 as compiler and Q_OBJECT is in the SMainWindow class definition.

Thanks,

I think it is about MOC ing , whatever it is. I need to do more readings.
Thanks guys.

Problem is solved. If you work with visual studio any class that is derived from a QT class has to be moced. then output of the moc operation should be added to cpp file of the derived class (not in header)
how moc a header
1) Add qt bin directory to your path
2)Open cmd and cd to the location of the header
3)moc header.h > header.cpp
4)work on your new header.cpp

No, that's not true.

1) Add qt bin directory to your path

3)moc header.h > header.cpp
4)work on your new header.cpp

Or run "qmake -project" and then "qmake -tp vc" when you start developing a project. Then Visual Studio will be mocing files for you by itself.

wysote,
you are absolutely right !
These are the steps to automate all mocing and .ui to .h conversion
1-)Make sure QT Add in for Visual Studio is installed
2-)Create a a qt project with qmake
qmake -project
qmake myproject.pro


3-)Open Visual Studio | Click on QT menu | Open Qt Project File

and you are all set , all mocings and uic ings are taken care automatically by QT add in.

Beautiful!
