I tried it but not work.
I created menus using QMenuBar::addAction(QAction*), to take the style of maemo menus.

Thank you,

That means you did something wrong.

I created menus using QMenuBar::addAction(QAction*), to take the style of maemo menus.

addAction creates QAction, not a QMenu as you can guess from the method name. Also it's not clear to me how style of Maemo menus is involved in this.

main.cpp

#include <QMainWindow>
#include <QMenuBar>
#include <QDebug>

#include "application.h"

int
main (int argc, char **argv)
{
    Application app(argc, argv);

    QAction action(QString("Action"), 0);

    QMenu menu("Fremantle");
    menu.addAction(&action);

    QObject::connect(&menu, SIGNAL(aboutToShow()),
                     &app, SLOT(menuAboutToShow()));
    QObject::connect(&menu, SIGNAL(aboutToHide()),
                     &app, SLOT(menuAboutToHide()));
    QObject::connect(&menu, SIGNAL(hovered(QAction*)),
                     &app, SLOT(menuHovered(QAction*)));

    QMainWindow win;
    win.menuBar()->addMenu(&menu);
    win.show();

    return app.exec();
