CFD Online Discussion Forums - Qtcreator cannot recongnize volScalarField

Dear sir:
I setup a oenfoam project with Qtcreator. I have include the header file for the volScalarField, but Qtcreator still prompt the error about "unknown type name 'volScalarField'.Could you please give me some adives abouth which header file should i inlclude further?

Code:

#include <argList.H>

#include <fvMesh.H>

#include <GeometricField.H>

#include <volFields.H>

#include <fvCFD.H>

#include <mathematicalConstants.H>

#include <fvOption.H>

#include <volFieldsFwd.H>

#include <rhoThermo.H>

#include <pimpleControl.H>

#include <surfFields.H>

#include <cpuInfo.H>

#include <linear.H>

#include <CodedSource.H>



using namespace Foam;



int main(int argc, char *argv[])

{   

#include <setRootCase.H>

#include <createTime.H>



 fvMesh mesh

    (

        IOobject

        (

            fvMesh::defaultRegion,

            runTime.timeName(),

            runTime,

            IOobject::MUST_READ

           //IOobject::NO_READ

        )

    );





 volScalarField TA

(

IOobject

(

"T",

runTime.timeName(),

mesh,

IOobject::MUST_READ,

IOobject::NO_WRITE

),

mesh

);

 Info<<TA.size();

}
