[SOLVED] unresolved external symbol

great88

I get error ( and see my code below ) :

@SqlQueryModel.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: virtual class QVariant __thiscall QAbstractItemModel::data(class QModelIndex const &,int)const " (_imp?data@QAbstractItemModel@@UBE?AVQVariant@@ABVQModelIndex@@H@Z) referenced in function "public: virtual class QVariant __thiscall SqlQueryModel::data(class QModelIndex const &,int)const " (?data@SqlQueryModel@@UBE?AVQVariant@@ABVQModelIndex@@H@Z)@

what am i doing wrong ?:

header :
@#ifndef SQLQUERYMODEL_H
#define SQLQUERYMODEL_H

#include <QSqlQueryModel>
#include <QModelIndex>
#include <QAbstractItemModel>

class SqlQueryModel : public QSqlQueryModel {
Q_OBJECT

private:

public:
SqlQueryModel(QObject * parent = 0);
QVariant data(const QModelIndex & item, int role ) const;
public slots:

};

#endif // SQLQUERYMODEL_H@

cpp :
@#include "SqlQueryModel.h"

SqlQueryModel::SqlQueryModel(QObject *parent) : QSqlQueryModel(parent) {

}

QVariant SqlQueryModel::data(const QModelIndex & item, int role ) const {
if (item.column() == 1 && role == Qt::TextAlignmentRole) {
return Qt::AlignRight;
} else {
return QAbstractTableModel::data(item, role);
}
}@

Does this compile for anyone ?

Hi,

if you replace this ligne code :
@
return QAbstractTableModel::data(item, role);
@

with this one :

@
return QSqlQueryModel::data(item, role);
@

it will compile !

Thank you ! That works .
