[SOLVED]Cannot execute my slot when menu item was clicked.

[count]

Hi All!
May be some of you know how to help me.

I want create menu in my programm, then i tried to connect new menu item with my private slot via next code:
@connect(ui->newPack, SIGNAL(triggered()), this, SLOT(addNew()));@

But, when menu item was clicked nothing was happens. If i write:
@ui->newPack->trigger();@
slot addNew() executes, thus connection works.

Also, if i write:
@connect(ui->newPack, SIGNAL(triggered()), this, SLOT(close()));@
it works fine...

Thanks.

UPD
There is sources.
mainwindow.h file:
@namespace Ui {
class MainWindow;
}

class MainWindow : public QMainWindow {
Q_OBJECT
public:
MainWindow(QWidget *parent = 0);
~MainWindow();

protected:
void changeEvent(QEvent *e);

private:
Ui::MainWindow *ui;

private slots:
void addNew();
};@

mainwindow.cpp file:
@MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
connect(ui->newPack, SIGNAL(triggered()), this, SLOT(addNew()));
}

void MainWindow::addNew()
{
ui->mdiArea->addSubWindow(new QuestionList);
...
}@

Oh. The problem was that added QMdiSubWindow didn't shown automaticaly, then, when i execute addNew from window constructor it's executes and shown correctly, but, in other cases i should execute qMdiSubWindow->show(); manually.
Now AddNew slot looks like this:
@void MainWindow::addNew()
{
ui->mdiArea->addSubWindow(new QuestionList);
...
ui->mdiArea->subWindowList().last()->show();
}@
and all works fine.

Never mind.

Thank you.
