QSystemTrayIcon +Qt 5.5 Ubuntu 14.04

[e.n.]

QSystemTrayIcon don`t emit signal "activated" when the icon clicked. I read that in the previous version it was a bug, but it should have been corrected.

I have Qt 5.5.0 + Ubuntu 14.04 (Gnome).

tray.h

class MainWindow : public QMainWindow
{
    Q_OBJECT
 
public:
    explicit MainWindow(QWidget *parent = 0);
    ~MainWindow();
 
private slots:
    void showMsg(QSystemTrayIcon::ActivationReason reason);
 
private:
    QSystemTrayIcon *trIcon;
    QAction *actClose;
    QMenu *menu;
 
};

class MainWindow : public QMainWindow
{
    Q_OBJECT

public:
    explicit MainWindow(QWidget *parent = 0);
    ~MainWindow();

private slots:
    void showMsg(QSystemTrayIcon::ActivationReason reason);

private:
    QSystemTrayIcon *trIcon;
    QAction *actClose;
    QMenu *menu;

};

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent)
{
 
    actClose = new QAction("Close", this);
    ...
 
    this->menuBar()->setNativeMenuBar(false);
    menu = menuBar()->addMenu(tr("&File"));
    menu->addAction(actClose);
 
    trIcon = new QSystemTrayIcon(this);
    trIcon->setIcon(QIcon(":/main_icon.png"));
    trIcon->setContextMenu(menu);
 
 
    connect(trIcon, &QSystemTrayIcon::activated, this, &MainWindow::showMsg);
 
    trIcon->show();
 
 
}
 
MainWindow::~MainWindow()
{
}
 
void MainWindow::showMsg(QSystemTrayIcon::ActivationReason reason)
{
    qDebug() << "show message";
 
}

...
MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent)
{

    actClose = new QAction("Close", this);
    ...

    this->menuBar()->setNativeMenuBar(false);
    menu = menuBar()->addMenu(tr("&File"));
    menu->addAction(actClose);

    trIcon = new QSystemTrayIcon(this);
    trIcon->setIcon(QIcon(":/main_icon.png"));
    trIcon->setContextMenu(menu);


    connect(trIcon, &QSystemTrayIcon::activated, this, &MainWindow::showMsg);

    trIcon->show();


}

MainWindow::~MainWindow()
{
}

void MainWindow::showMsg(QSystemTrayIcon::ActivationReason reason)
{
    qDebug() << "show message";

}

Anybody have any idea? Thank)

shouldn't that like more like this? :

QObject::connect(mytrayicon, SIGNAL(activated(QSystemTrayIcon::ActivationReason )), this, SLOT(on_activated(QSystemTrayIcon::ActivationReaso n)));

QObject::connect(mytrayicon, SIGNAL(activated(QSystemTrayIcon::ActivationReason )), this, SLOT(on_activated(QSystemTrayIcon::ActivationReaso n)));

That would work as well.
Your syntax is the traditional macro using connect(), the thread started used the pointer-to-member-function syntax (an addition in Qt5).
