Signals and Slots in dll

[ChristianEhrlicher]

It is Q_CC_MSVC and not QT_CC_MSVC
You maybe have not set BUILD_QGRID when building your dll (as the error states you're using dllimport == Q_DECL_IMPORT).
Please read about importing / exporting symbols in your favorite msvc book / at msdn.mcrosoft.com

Sorry my mistake (Q and QT misspell),

i defined BUILD_QGRID in .pro file as DEFINES += BUILD_QGRID
also it shows in the project settings as /D "BUILD_QGRID"

the problem is due to the Q_OBJECT directive.

if i comment the line and the slots in the class it works fine.

also the error is stating "definition of dllimport static data member not allowed"

and warnings regarding exporting. i didn't got these errors.

is there some other way to define the BUILD_QGRID, like in the cpp file ?
