    <p>I am using Ubuntu 12.04 and, while I can create a tray icon with a usable menu, I cannot control its actions:</p> <pre><code> trayIcon = new QSystemTrayIcon(this); trayIcon-&gt;setIcon(QIcon(":/icons/Pictures/icon.png")); trayIcon-&gt;setToolTip(QString("Hello there...")); connect(trayIcon,SIGNAL(activated(QSystemTrayIcon::ActivationReason)),this,SLOT(clickSysTrayIcon(QSystemTrayIcon::ActivationReason))); connect(this,SIGNAL(minimized()),this,SLOT(hide()),Qt::QueuedConnection); QMenu *changer_menu = new QMenu; Show_action = new QAction(tr("S&amp;how"),this); Show_action-&gt;setIconVisibleInMenu(true); connect(Show_action, SIGNAL(triggered()), this, SLOT(showClicked())); changer_menu-&gt;addAction(Show_action); changer_menu-&gt;addSeparator(); Quit_action = new QAction(tr("&amp;Quit"), this); Quit_action-&gt;setIconVisibleInMenu(true);; connect(Quit_action, SIGNAL(triggered()), this, SLOT(close_minimize())); changer_menu-&gt;addAction(Quit_action); trayIcon-&gt;setContextMenu(changer_menu); trayIcon-&gt;show(); </code></pre> <p>The clickSysTrayIcon(QSystemTrayIcon::ActivationReason) is the following:</p> <pre><code>void MainWindow::clickSysTrayIcon(QSystemTrayIcon::ActivationReason reason) { //reason is a variable that holds the type of activation or click done on the icon tray qDebug() &lt;&lt; "I'm in!"; } </code></pre> <p>and, defined at the header file as:</p> <pre><code>private Q_SLOTS: void clickSysTrayIcon(QSystemTrayIcon::ActivationReason reason); </code></pre> <p>However, I cannot get the "I'm in!" message to be shown. I've tried to make it work with left/right clicks, with middle click and with mouse wheel, but I never see this message being outputed.</p> <p>What is wrong?</p> <p>EDIT: It seems that something's wrong with the specific system, Ubuntu 12.04, because it doesn't use tray icons any more and only indicators. So, there's a program which uses the tray icons and they convert them into indicators. But, then the features of indicators are gone. I know that it's the system to blame, because the same program, under the very same code, works perfectly under Lubuntu 12.04 with the LXDE desktop.</p> <p>I blame Ubuntu for this. The sni-qt package doesn't do a very good migration from tray icons to indicators, providing that indicators can interact on click, on roller etc. It's a shame! Any solutions to this problem?</p> <p>My bounty ends, so if there's someone who can address the problem I would be thankful!</p>

    3. CODo you receive some debug output (errors, etc.) I have tested testing it after that, but it worked on Kubuntu, also, so I was unable to reproduce the problem.

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
