Hello,
I have QMainWindow and i created a QMenuBar added QMenu in it with actions that are connected with some slots but when i run appliacation and want to use some options from menu the slot is not called, i dont know where is a problem.

Here is main window constructor

Qt Code: 
  1. Window::Window(QWidget *parent) :
  2.     QMainWindow(parent),
  3.     ui(new Ui::Window)
  4. {        
  5.     ui->centralWidget = new QWidget;
  6.     setCentralWidget(ui->centralWidget);
  7.     ui->setupUi(this);
  8.     ui->render = new Render();
  9.  
  10.     ui->menuBar = new QMenuBar;
  11.  
  12.     ui->menuAnimacja = new QMenu;
  13.  
  14.     createAnimationActions();
  15.     ui->menuAnimacja->addAction( ui->actionStart );
  16.     ui->menuAnimacja->addAction( ui->actionStop );
  17.     ui->menuBar->addMenu( ui->menuAnimacja );
  18.  
  19. }
To copy to clipboard, switch view to plain text mode 

and here i am creating actions

Qt Code: 
  1. void Window::createAnimationActions()
  2. {
  3.     ui->actionStart = new QAction(this);
  4.     connect(ui->actionStart, SIGNAL(triggered()), this, SLOT(startAnimation()));
  5.  
  6.     ui->actionStop = new QAction(this);
  7.     connect(ui->actionStop, SIGNAL(triggered()), this, SLOT(stopAnimation()));
  8. }
