I've create the gui view and set "setQuitOnLastWindow" to false. The
problem i'm having is that when the app gui is closed (the app continues
running on background), but the user can't open it again. How can i reopen
the gui view when the user clicks on the menu button of the app?.
The main code:

> QGuiApplication *app = SailfishApp::application(argc, argv);
> QQuickView *view = SailfishApp::createView();
> app->setQuitOnLastWindowClosed(false);
> view->setSource(SailfishApp::pathTo("qml/background.qml"));
> view->show();

MyTimer is just a class inherited from QTimer which prints "Running" each 3
secs.
