[Qt-interest] 2 menubar not working

[Sujan Dasmahapatra]

Dear Friends
I have a doubt ! Can we have 2 menuBar() for a single QMainWindow ?
Sometimes I want to use 1 menuBar and sometimes I want to goto to a
different mode where a 2nd menuBar should come.
Is this code below correct would there be corresponding menuBars will be set
when user wants to change the menuBar !!


Kindly see the code snippet :
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
class MainWindow:public QMainWindow
{
private:
 QMenuBar *menuBar1, * menuBar2;
QPushButton * button1, *button2;
protected slots:
     void callMenuBar1();
     void callMenuBar2();
}

MainWindow::MainWindow()
{
menuBar1 = new  QMenuBar;
menuBar2 = new  QMenuBar;
button1 = new QPushButton;
button2 = new QPushButton;
connect(button1,SIGNAL(clicked()),this,SLOT(callMenuBar1()));
connect(button2,SIGNAL(clicked()),this,SLOT(callMenuBar2()));
}

void MainWindow::callMenuBar1()
{
   setMenuBar(menuBar1);
}

void MainWindow::callMenuBar2()
{
   setMenuBar(menuBar2);
}
