If you have hidden an OS X Application with Cmd-H (aka Apple-H = ⌘-H) the hidden window cannot be shown again by calling slot show(). In this case you must call

<code>
raise();
// maybe additionally to activate the window:
activateWindow();
</code>

If you have installed a system tray icon with [http://doc.qt.io/qt-5/qsystemtrayicon.html QSystemTrayIcon] you can add a menu entry and connect the [http://doc.qt.io/qt-5/qaction.html QAction's] triggered() signal with the respecitve slots.
