QT5:ui_mainwindow.h和moc_mainwindow.cpp

一.ui_mainwindow.h

#ifndef UI_MAINWINDOW_H
#define UI_MAINWINDOW_H

#include <QtCore/QVariant>
#include <QtWidgets/QApplication>
#include <QtWidgets/QMainWindow>
#include <QtWidgets/QMenuBar>
#include <QtWidgets/QStatusBar>
#include <QtWidgets/QWidget>

QT_BEGIN_NAMESPACE

class Ui_MainWindow
{
pubic:
  QWidget* centralwidget;
  QMenuBar* menubar;
  QStatusBar* statusbar;

  void setupUi(QMainWindow* MainWindow)
  {
    if (MainWindow->objectName().isEmpty())
      MainWindow->setObjectName(QString::fromUtf8("MainWindow"));
    
    MainWindow->resize(800, 600);
    centralwidget = new QWidget(MainWindow);
    centralwidget->setObjectName(QString::fromUtf8("centralwidget"));
    MainWindow->setCentralWidget(centralwidget);
    menubar = new QMenuBar(MainWindow)
    menubar->setObjectName(QString::fromUtf8("menubar"));
    MainWindow->setMenuBar(menubar);
    statusbar = new QStatusBar(MainWindow);
    statusbar->setObjectName(QString::fromUtf8("statusbar"));
    MainWindow->setStatusBar(statusbar);

    retranslateUi(MainWindow);

    QMetaObject::connectSlotsByName(MainWndow);

  } // setupUi

  void retranslateUi(QMainWindow* MainWindow)
  {
    MainWindow->setWindowTitle(QCoreApplication::translate("MainWindow", "MainWindow", nullptr));
  }  //retranslateUi

};

namespae Ui {
  class MainWindow : public Ui_MainWindow {};
}

二.moc_mainwindow.cpp

 

QT中的信号（Signals）和槽（Slot）的机制进行通信，需要继承QObject基类，继承这个基类就会生成一个moc文件，没有这个文件就不能使用信号和槽

 

#include <memory>
#include "../../test/mainwindow.h"
#include <QtCore/qbytearray.h>
#include <QtCore/qmetatype.h>

#if !defined(Q_MOC_OUTPUT_REVISION)
#error "The header file 'mainwindow.h' doesn't include <QObject>. "
#elif Q_MOC_OUTPUT_REVISION != 67
#error "This file was generated using the moc from 5.13.2. It"
#error "cannot be used with the include files from this version of Qt."
#error "(The moc has changed too mush.)"
#endif
