[提问]本人新学菜虫，求帮助 [复制链接]

前两天才开始弄QT,球也不会啊！好不容易编了个，弄不清是哪里错了，诚信求教

要求：制作一个窗体，有标题栏，菜单栏，工具栏，状态栏；
      菜单栏和状态栏分别是：add、delete、modify、search四个选项
      要求指定菜单项时，状态栏有相应的显示

代码如下：mainwindow.h

#include <qapplication.h>
#include <qmainwindow.h>
#include <qmenubar.h>
#include <qpopupmenu.h>
#include <qtoolbar.h>
#include <qaction.h>
#include <qstatusbar.h>
class mainWindow : public QMainWindow
{
Q_OBJECT

public:
  mainWindow(QWidget* parent=0,const char* name=0);
  ~mainWindow();

  QMenuBar* menubar;
  QPopupMenu* fileMenu;
  QAction* fileAdd;
  QAction* fileDel;
  QAction* fileModify;
  QAction* fileSearch;
  
  QToolBar* toolBar;
  
  QStatusBar* status;
  
private slots:
  void add();
  void del();
  void modify();
  void search();
  
};

mainWindow.cpp

#include "mainwindow.h"
mainWindow::mainWindow(Qwidget* parent,const char* name):QMainWindow(parent,name)
{

menubar = new QMenuBar(this);
fileMenu = new QPopupMenu(this);
menubar->insertItem( "&file", fileMenu );

fileAdd = new QAction("add","&Add",CTRL+KEY_A,this);
fileDel = new QAction("delete","&Delete",CTRL+KEY_D,this);
fileModify = new QAction("modify","&Modify",CTRL+KEY_M,this);
fileSearch = new QAction("search","&Search",CTRL+KEY_S,this);

fileAdd->addTo(fileMenu);
fileDel->addTo(fileMenu);
fileModify->addTO(fileMenu);
fileModify->addTo(fileMenu);

toolBar = new QToolBar(this);

fileAdd->addTo(toolBar);
fileDel->addTo(toolBar);
fileModify->addTo(toolBar);
fileSearch->addTo(toolBar);
status = new QStatusBar(this);

fileAdd->setStatusTip("yangruibo");
fileDelete->setStatusTip("0921010121");
fileModify->setStatusTip("yangruibo");
fileSearch->setStatusTip("0921010121");
}
MainWindow::~MainWindow()
{
}

mian.cpp

#include <qapplication.h>
#include "mainwindow.h"

int main(int argc, char *argv[]){
QApplication app(argc,argv);

mainWindow w ;

//设置窗口的尺寸
w.resize(700,600);
//设置窗口标题栏文字
//w.setWindowTitle(QObject::tr("0921010121yrb"));
w.show();

return app.exec();
}

用得是QT3，老师要求，诚心求助，谢谢大家

main.cpp中添加标题栏的一列已经注释了，下面是问题：

我觉得才“前两天”开始学用Qt就写这么复杂的东西，难度过大啊……
另外说说是什么地方的问题，看全部的代码太麻烦了

就是第四页显示的，说实话，这是大作业，没办法啊

高手都去哪了？灌水的就算了，真没兴趣玩儿

建议找本书看看，着急时想起来让别人帮忙了。
这样的例子，Qt自带了很多，自己慢慢琢磨吧。

能分析分析问题吗？别扯这有的没的

从这一行
mainWindow::mainWindow(Qwidget* parent,const char* name):QMainWindow(parent,name)
和这一行
MainWindow::~MainWindow()
来看
大小写错误

谢谢啊，我修改一下试试

fileModify->addTO(fileMenu);
这一行写的也有问题！

只要窗体不要功能的话其实还好。。
