[solved]expected class-name before '{' token

[shahid.pk]

well i am new to Qt but not very new to c++ the error comes in effect for recursive inclusions but look at my code i don't see any recursive inclusions..i think this is something else will anyone help me with following..

here is the sortdialog.h file (taken from a qt book Jasmin Blanchette; Mark Summerfield)
@#ifndef SORTDIALOG_H
#define SORTDIALOG_H

#include <QDialog>
#include "ui_sortdialog.h"

class SortDialog : public QDialog, public Ui::SortDialog
{

Q_OBJECT

public:

SortDialog(QWidget *parent = 0);

void setColomnRange(QChar first, QChar last);

};

#endif@

and here is its cpp file sortdialog.cpp

@#include <QtGui>
#include "sortdialog.h"

SortDialog::SortDialog(QWidget *parent) : QWidget(parent) //constructor
{

setupUi(this);

SecondaryGroupBox->hide();

TertiaryGroupBox->hide();

layout->setSizeConstraint(QLayout::setFixedSize);

setColomnRange('A','Z');

}

//setcolomnrange function..
void SortDialog::setColomnRange(QChar first,QChar end)
{

PrimaryColomnBox->clear();

SecondaryColomnBox->clear();

TertiaryColomnBox->clear();

SecondaryColomnBox->addItem(tr("none"));

TertiaryColomnBox->addItem(tr("none"));

PrimaryColomnBox->setMinimumSize(SecondaryColomnBox->sizeHing());

QChar ch = first;

while(ch <= end)
{
PrimaryColomnBox->addItem(QString(ch));

      SecondaryColomnBox->addItem(QString(ch));

      TertiaryColomnBox->addItem(QString(ch));

      ch = ch.unicode()+1;    

} //end while

} //end setColomnRange@

and here is the main.cpp

@#include <QApplication>

#include "sortdialog.h"

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

QApplication app(argc,argv);

SortDialog *dialog = new SortDialog;

dialog->setColomnRange('S','W');

dialog->show();

return app.exec();

}@

now my mingGW compiler gives me error in line 3 in main.cpp which is the inclusion of sortdialog.h than in sortdialog.h on line 12 it points to the opening { of
the class and says "expected class-name before '{' token "
Note:
(my code is not exactly the same to that of the book code i have made some changes for learning purpose)

Your problem is probably located in :
@#include "ui_sortdialog.h"@

Have you created the .ui like in the exemple? and generated the file ui_sortingdialog.h with uic?

You also don't call the good parent constructor in @ SortDialog::SortDialog(QWidget *parent) : QWidget(parent) //constructor@
From your sortdialog.h, it should be :
@ SortDialog::SortDialog(QWidget *parent) : QDialog(parent) //constructor@

Yes, the error on line 12 is cause because Ui::SortDialog is not recognized as a class (aka the declaration of Ui::SortDialog is missing). Please have a look at "ui_sortdialog.h" as advised by "redkite":http://developer.qt.nokia.com/member/976

bq. Your problem is probably located in :
#include "ui_sortdialog.h"

yes i have created the .ui and ui_sortdialog.h but still don't know why my Ui::SortDialog is not declared there.i think it is declared there..
Thanks for pointing out the constructor mistake @redkite

UPDATE

oh my god i corrected it it was a silly mistake.the name of that class in ui_sortdialog.h was not Sortdialog but just dialog.it was silly of me but thank you very much @redkite and @leon.anavi you pointing that thing out.
