QMenu *fileMenu = new QMenu("File"); fileMenu->setTitle("File Options");
QMenuBar *menuBar = new QMenuBar(); QMenu *fileMenu = menuBar->addMenu("File"); fileMenu->setTitle("File Options");In this example, we create a new QMenuBar object and add a new QMenu object called "fileMenu" to it with the title "File". We then call the setTitle function to change its title to "File Options". The package library used for this function is the Qt framework, specifically the QtGui library.
