Menu Problem

[rahulgogoi]

hello friends

Actually i am not able to contruct a menu in my App..the code i have written is like that…

#include "menumainwindow.h"
 
menumainwindow::menumainwindow(QWidget *parent)
    : QMainWindow(parent)
{
 
 
 showAct = new QAction(("&Show"), this);
 connect(showAct, SIGNAL(triggered()),label1, SLOT(show()));
 hideAct = new QAction(("&Hide"), this);
 connect(hideAct, SIGNAL(triggered()),label1, SLOT(hide()));
 exitAct = new QAction(("&Exit"), this);
 connect(exitAct, SIGNAL(triggered()),qApp, SLOT(quit()));
 bar = menuBar()->addMenu("&File");
 bar->addAction(showAct);
 bar->addAction(hideAct);
 bar->addSeparator();
 bar->addAction(exitAct);
        setCentralWidget(bar);
 
}

#include "menumainwindow.h"
  
menumainwindow::menumainwindow(QWidget *parent)
    : QMainWindow(parent)
{
  
  
 showAct = new QAction(("&Show"), this);
 connect(showAct, SIGNAL(triggered()),label1, SLOT(show()));
 hideAct = new QAction(("&Hide"), this);
 connect(hideAct, SIGNAL(triggered()),label1, SLOT(hide()));
 exitAct = new QAction(("&Exit"), this);
 connect(exitAct, SIGNAL(triggered()),qApp, SLOT(quit()));
 bar = menuBar()->addMenu("&File");
 bar->addAction(showAct);
 bar->addAction(hideAct);
 bar->addSeparator();
 bar->addAction(exitAct);
        setCentralWidget(bar);
  
}

To copy to clipboard, switch view to plain text mode 

here it will display show,hide,exit menu but i want it to show when i click the “file”..so anything wrong in the code..please suggest
