How to synchronize QWidgets with menu bar?

I a开发者_Go百科m new to Qt creator. I have a stacked widget with 3 pages. I also have a menu bar that contains : open \\ create. The QWidget contains 2 pages. I would like to ask how can I synchronize Open with first page and create from menu bar with second page from stacked widget?

I did write: ui->stackedWidget->show(); but it's printing the second page to both open and create.

Need some help.

You have to declare two slots in your MainWindow class. For instance:

class MainWindow : public QMainWindow
  {
  ...
public slots:
  void slotOpen() ;
  void slotCreate() ;
  ...
  } ;

Then, in your MainWindow constructor (assuming your menu actions are actionOpen and actionCreate):

connect (ui -> actionOpen, SIGNAL(triggered()), SLOT(slotOpen())) ;
connect (ui -> actionCreate, SIGNAL(triggered()), SLOT(slotCreate())) ;

The slot functions:

void MainWindow::slotOpen()
  {
  ui -> stackedWidget -> setCurrentIndex(0) ;
  }

void MainWindow::slotCreate()
  {
  ui -> stackedWidget -> setCurrentIndex(1) ;
  }

You can connect the menu actions to the QStackedWidget Slot setCurrentIndex. This will allow you to display the correct widget when clicking on the menu.
