我完全按照“Qt 4 程序设计指南”编写代码，但编译是经常出现
error: ‘Ui’ has not been declared

这个错误，那位知道为什么阿？

我把sortdialog.h中的class SortDialog : public QDialog, public Ui::SortDialog
改为 class SortDialog : public QDialog, public Ui::Dialog

终于成功运行了，谢谢 XChinux !!

你的sortdialog.h的宏定义错了，
和ui_sortdialog.h里的宏定义一样，所以实际上ui_sortdialog.h并没有被包含进去。
把sortdialog.h开头的宏改一下，改成和文件名一致的。

它总是说Ui没定义，Ui不是在头文件里已经定义了么？？

QApplication.h
不存在这样的文件。
应该是qapplication.h
或者
QApplication

我是编译 Sort那个程序的：

main.cpp 如下：

#include <QApplication.h>

#include "sortdialog.h"

int main(int argc,char *argv[])
{
QApplication app(argc,argv);
SortDialog dialog;
dialog.setColumnRange('C','F');
dialog.show();
return app.exec();
}

sortdialog.h 如下：

#ifndef UI_SORTDIALOG_H
#define UI_SORTDIALOG_H

#include <QtGui/QDialog>

#include "ui_sortdialog.h"

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

public:
SortDialog(QWidget* parent=0);
~SortDialog();

public slots:
void setColumnRange(QChar first,QChar last);

};

#endif

sortdialog.cpp如下：

#include "sortdialog.h"

SortDialog::SortDialog(QWidget* parent):QDialog(parent)
{
setupUi(this);
secondaryGroupBox->hide();
tertiaryGroupBox->hide();
setColumnRange('A','z');
}

SortDialog::~SortDialog()
{
}

void SortDialog::setColumnRange(QChar first,QChar last)
{
primaryColumnComboBox->clear();
secondaryColumnComboBox->clear();
tertiaryColumnComboBox->clear();

secondaryColumnComboBox->insertItem(0,tr("None"));
tertiaryColumnComboBox->insertItem(0,tr("None"));

primaryColumnComboBox->setMinimumSize(secondaryColumnComboBox->sizeHint());
QChar ch=first;
while(ch<=last)
{
primaryColumnComboBox->insertItem(0,ch);
