QMenu and signals

[mattia]

Hello, i created a menu entry in this way:

QMenuBar *twmmenuBar;
    twmmenuBar = new QMenuBar(twmMainWindow);
 
    QMenu *menuTools;
    menuTools = new QMenu(twmmenuBar);
    menuTools->setObjectName(QString::fromUtf8("menuTools"));
    twmmenuBar->addAction(menuTools->menuAction());
    menuTools->setTitle(QApplication::translate("twmMainWindow", "Tools", 0,  QApplication::UnicodeUTF8));

QMenuBar *twmmenuBar;
    twmmenuBar = new QMenuBar(twmMainWindow);

    QMenu *menuTools;
    menuTools = new QMenu(twmmenuBar);
    menuTools->setObjectName(QString::fromUtf8("menuTools"));
    twmmenuBar->addAction(menuTools->menuAction());
    menuTools->setTitle(QApplication::translate("twmMainWindow", "Tools", 0,  QApplication::UnicodeUTF8));

To copy to clipboard, switch view to plain text mode 

why this connections doesn't work?

connect ( ui.menuTools , SIGNAL ( triggered( QAction *) ) , this , SLOT ( mySlot QAction * ) ) );

connect ( ui.menuTools , SIGNAL ( triggered( QAction *) ) , this , SLOT ( mySlot QAction * ) ) );

To copy to clipboard, switch view to plain text mode 

I get this error:

error: ‘SIGNAL’ was not declared in this scope

error: ‘SIGNAL’ was not declared in this scope

To copy to clipboard, switch view to plain text mode 

i checked here
http://doc.trolltech.com/4.2/qmenu.html#triggered
and menuTools is QMenu Object and it should be able to emit the triggered( QAction *) signal.
My needs is throw a slot when menuTools is clicked.
thx
