        QtGui.QSystemTrayIcon.__init__(self, icon, parent)

        menu = QtGui.QMenu(parent)
        exitAction = menu.addAction("Exit")
        helloAction = menu.addAction("Hello World")

        self.setContextMenu(menu)
        QtCore.QObject.connect(exitAction, QtCore.SIGNAL('triggered()'), self.exit)
        QtCore.QObject.connect(helloAction, QtCore.SIGNAL('triggered()'), self.hello)

    def exit(self):
        QtCore.QCoreApplication.exit()

    def hello(self):
       msg = QtGui.QMessageBox.information(self.parent(), "Hello", "Hello World")

def main():
    app = QtGui.QApplication(sys.argv)

    w = QtGui.QWidget()
    trayIcon = SystemTrayIcon(QtGui.QIcon("qtLogo.png"), w)

    trayIcon.show()
    sys.exit(app.exec_())

if __name__ == '__main__':
    main()

Figured it out.

You need to set app.setQuitOnLastWindowClosed(False). So:

app = QtGui.QApplication(sys.argv)
app.setQuitOnLastWindowClosed(False)

That will stop it from exiting when the window closes.
