新手初学QT,载入UI的问题向大神们请教
在网上抄了使用UI的几段代码.发现运行不起来.代码如下,请大神帮忙看一下问题,不胜感激
UI文件的名称是 RegDialog.ui
main.cpp:

C/C++ code


#include <QApplication>
#include "RegDlalog.h"

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    RegDlalog *dialog = new RegDlalog;
    dialog->show();
    return app.exec();
}

RegDialog.h:

C/C++ code


#ifndef REGDLALOG_H
#define REGDLALOG_H

#include <QDialog>
#include <QWidget>
#include "ui_RegDialog.h"

namespace Ui
{
    class RegDialog;
}

class RegDialog : public QWidget
{
    Q_OBJECT
public:
    RegDialog(QWidget *parent = 0);
    ~RegDialog();

private:
    Ui::RegDialog *ui;
};


#endif // REGDLALOG_H

RegDialog.cpp

C/C++ code


#include <QtGui>
#include "RegDlalog.h"
#include "ui_RegDialog.h"

RegDialog::RegDialog(QWidget *parent) :
    QWidget(this),
    ui(new Ui::RegDialog)
{
    ui->setupUi(this);
}

RegDialog::~RegDialog()
{
    delete ui;
}
