Problems Adding Menu to Menu Bar on Mac
-
I have been having problems adding a menu item to the built in menu bar in a Qt desktop application. I copied the code provided in the QMainWindow class reference documentation for creating a menu to a very simple application. Unfortunately, it did not work. I am simply trying to add a "File" menu to the menu bar. I am running Mac OSX 10.9.3 and Qt Creator 5.3.1.
The screenshots of my code are below. I tried both the uncommented and commented code in the mainwindow.cpp source.
MainWindow.cpp:
@#include "mainwindow.h"
#include "ui_mainwindow.h"MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
//myMenuBar = menuBar();
//fileMenu = myMenuBar -> addMenu(tr("&File"));fileMenu = menuBar() -> addMenu(tr("&File")); ui->setupUi(this);
}
MainWindow::~MainWindow()
{
delete ui;
}@mainwindow.h:
@#ifndef MAINWINDOW_H
#define MAINWINDOW_H#include <QMainWindow>
#include <QMenuBar>
#include <QMenu>namespace Ui {
class MainWindow;
}class MainWindow : public QMainWindow
{
Q_OBJECTpublic:
explicit MainWindow(QWidget *parent = 0);
~MainWindow();private:
Ui::MainWindow ui;
QMenuBar myMenuBar;
QMenu* fileMenu;
};#endif // MAINWINDOW_H
@main.cpp:
@#include "mainwindow.h"
#include <QApplication>int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;
w.show();return a.exec();
}

@Any help would be really appreciated! Thank you!
Note: I know using setNativeMenuBar(false) works, but I would like the mac os native menu bar to work: the one that is displayed in the top-most left corner.

You need to write that code after ui->setupUi(this) call. Otherwise, the UI is not ready for the changes.
