Qt QSystemTrayIcon not sending activated signal

I'm trying to copy the Qt systray example here: http://doc.qt.io/archives/4.6/desktop-systray.html

Things seem to be working except that the QSystemTrayIcon object is not sending an activate signal.

Here's my mainwindow.cpp code:

#include <QtGui>

#include "mainwindow.h"
#include "ui_mainwindow.h"

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent), ui(new Ui::MainWindow)
{
    ui->setupUi(this);
    QMessageBox::information(0, tr("Systray"),
                              tr("Loaded."));
    createTrayIcon();

    connect(trayIcon,SIGNAL(activated(QSystemTrayIcon::ActivationReason)),this,
            SLOT(iconActivated(QSystemTrayIcon::ActivationReason)));

    trayIcon->show();
}

void MainWindow::createTrayIcon()
{
    trayIcon = new QSystemTrayIcon(this);

}

void MainWindow::iconActivated(QSystemTrayIcon::ActivationReason reason)
{
    QMessageBox::information(0, tr("Systray"),
                              tr("Testing"));

}

void MainWindow::messageClicked()
{
     QMessageBox::information(0, tr("Systray"),
                              tr("Sorry, I already gave what help I could.\n"
                                 "Maybe you should try asking a human?"));
 }

MainWindow::~MainWindow()
{
    delete ui;
}

I'm using Qt 4.5.2 on Windows XP SP2. Could this be an issue with Windows XP? Or am I doing something wrong? I don't have a QIcon set for the trayIcon. Is that a problem?

Any help would be appreciated.

Thanks! Jieren

Well if anyone's interested, I found the issue. The problem was actually in the header file.

Here's the one that works:

#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QWidget>
#include <QSystemTrayIcon>


class MainWindow : public QWidget
{
    Q_OBJECT

public:
    MainWindow();

private slots:
    void iconActivated(QSystemTrayIcon::ActivationReason reason);
private:
    QAction *minimizeAction;
     QAction *maximizeAction;
     QAction *restoreAction;
     QAction *quitAction;

     QSystemTrayIcon *trayIcon;
    void createActions();
    void createTrayIcon();

    void messageClicked();
};

#endif // MAINWINDOW_H

iconActivated needs to be declared as a private slot. I had it declared as a private function.
