problem in declaring QDirModel

[prasanth.nvs]

I write a class which is extended from QWidget and Now i declare a QDirModel object in .h file and it instantiated in My class contructor... when i compile it gives the following error.. I include all the things whic are necessary..

model.h:18: error: ISO C++ forbids declaration of 'QDirModel' with no type
model.h:18: error: expected ';' before '*' token
model.cpp: In constructor 'DirModel:irModel(QWidget*)':
model.cpp:10: error: 'iModel' was not declared in this scope
model.cpp:10: error: expected type-specifier before 'QDirModel'
model.cpp:10: error: expected `;' before 'QDirModel'
model.cpp: At global scope:

code is :

class DirModel: public QWidget
{
 
public:
    DirModel(QWidget* aParent);
    ~DirModel();
 
    void AddFolder(const QString& aFolderName,int aParent = 0);
 
public:
    QDirModel* iModel;
    QTreeView* iView;
    int iFolderId;
};
 
 
DirModel::DirModel(QWidget* aParent)
         :QWidget(aParent)
{
    iModel = new QDirModel(this);
    iModel->setReadOnly(false);
 
    iView  = new QTreeView(this);
    iView->setModel(iModel);
    iView->setRootIndex( iModel->index(QString( "/home/randy" ) ) );
}
 
 
DirModel::~DirModel()
{
 
}
 
void DirModel::AddFolder(const QString& aFolderName,int aParent)
{
//  iModel->mkdir(aParent,aFolderName);
 
}

class DirModel: public QWidget
{

public:
    DirModel(QWidget* aParent);
    ~DirModel();

    void AddFolder(const QString& aFolderName,int aParent = 0);

public:
    QDirModel* iModel;
    QTreeView* iView;
    int iFolderId;
};


DirModel::DirModel(QWidget* aParent)
         :QWidget(aParent)
{
    iModel = new QDirModel(this);
    iModel->setReadOnly(false);

    iView  = new QTreeView(this);
    iView->setModel(iModel);
    iView->setRootIndex( iModel->index(QString( "/home/randy" ) ) );
}


DirModel::~DirModel()
{

}

void DirModel::AddFolder(const QString& aFolderName,int aParent)
{
//  iModel->mkdir(aParent,aFolderName);

}

To copy to clipboard, switch view to plain text mode

You should add

class QDirModel;

class QDirModel;

To copy to clipboard, switch view to plain text mode 

Before DirModel class declaration. Or just include it.

i try the above two options
class QDirModel;
and also i include that header file...
even it gives the same errors above shown.

Could you attach the header and source file or something? Then we can spot it immediately. Otherwise we just have to keep guessing.
