错误:no matching function for call to setupUi

按照《C++ GUI Qt4编程》做那个对话框程序结果出错，用的是Qt Creator，

#include <QApplication>

#include <QDialog>



#include"ui_gotocelldialog.h"



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

{

   QApplication app(argc,argv);

   Ui::GoToCellDialog ui;

   QDialog *dialog=new QDialog;

   ui.setupUi(dialog);

   dialog->show();

   return app.exec();

}

ui_gotocelldialog.h是自动生成的，代码为：

#ifndef UI_GOTOCELLDIALOG_H

#define UI_GOTOCELLDIALOG_H



#include <QtCore/QVariant>

#include <QtGui/QAction>

#include <QtGui/QApplication>

#include <QtGui/QButtonGroup>

#include <QtGui/QDockWidget>

#include <QtGui/QHBoxLayout>

#include <QtGui/QHeaderView>

#include <QtGui/QLabel>

#include <QtGui/QLineEdit>

#include <QtGui/QPushButton>

#include <QtGui/QSpacerItem>

#include <QtGui/QVBoxLayout>

#include <QtGui/QWidget>



QT_BEGIN_NAMESPACE



class Ui_GoToCellDialog

{

public:

    QWidget *dockWidgetContents;

    QVBoxLayout *verticalLayout;

    QHBoxLayout *horizontalLayout;

    QLabel *label;

    QLineEdit *lineEdit;

    QHBoxLayout *horizontalLayout_2;

    QSpacerItem *horizontalSpacer;

    QPushButton *pushButton;

    QPushButton *pushButton_2;



    void setupUi(QDockWidget *GoToCellDialog)

    {

        ……

    } // setupUi



    void retranslateUi(QDockWidget *GoToCellDialog)

    {

        GoToCellDialog->setWindowTitle(QApplication::translate("GoToCellDialog", "GoToCell", 0, QApplication::UnicodeUTF8));

        label->setText(QApplication::translate("GoToCellDialog", "&Cell", 0, QApplication::UnicodeUTF8));

        pushButton->setText(QApplication::translate("GoToCellDialog", "OK", 0, QApplication::UnicodeUTF8));

        pushButton_2->setText(QApplication::translate("GoToCellDialog", "Cancel", 0, QApplication::UnicodeUTF8));

    } // retranslateUi



};



namespace Ui {

    class GoToCellDialog: public Ui_GoToCellDialog {};

} // namespace Ui



QT_END_NAMESPACE



#endif // UI_GOTOCELLDIALOG_H

错误信息为
E:\Qt\Dialog\QtDialog.cpp:-1: In function 'int qMain(int, char**)':
E:\Qt\Dialog\QtDialog.cpp:13: 错误:no matching function for call to 'Ui::GoToCellDialog::setupUi(QDialog*&)'
E:\Qt\Dialog\ui_gotocelldialog.h:42: candidates are: void Ui_GoToCellDialog::setupUi(QDockWidget*)

新手求教！

请统一到底是setupUi(QDockWidget*)还是setupUi(QDialog*

QDialog *dialog=new QDialog;
类型不匹配，应该是QDockWidget

这两个的区别是什么？书上是QDialog，自己生成的ui_gotocelldialog.h文件里面是QDockWidget，晕
