qt中ui如何使用 [复制链接]

我有三个文件：goog.ui        main.cpp          Windows.cpp           Windows.h  
如下：Windows.h
#ifndef WINDOWS_H
#define WINDOWS_H
#include "ui_goog.h"
#include <qmainwindow.h>
#include <QWidget>
  class Windows : public QMainWindow,public Ui::goog
  {
      Q_OBJECT
  public:
      Windows(QWidget *parent=0);
  };
#endif // WINDOWS_H

Windows.cpp

#include "Windows.h"
#include <QtGui>
  #include <QMessageBox>
#include <QSystemTrayIcon>
#include <QStringList>
Windows::Windows(QWidget *parent) : QMainWindow(parent)
  {
   setupUi(this);
}



main.cpp


#include <QApplication>
#include "Windows.h"
int main(int argc, char *argv[])
{
     QApplication app(argc, argv);
     Windows mainWin;
     mainWin.show();
     return app.exec();
}
请问我该如何才能运行它们（本人是菜鸟，希望各位不怕麻烦，说得详细些，谢谢！！）??
