I'd like to change the hover-over title of my app icon; such that, in the picture below, it reads "FOO" instead of "python". I'm showing the code I've used to import the app icon, and am thinking if there's a way, it must be a one liner underneath this. Anyone know?
if __name__ == '__main__':
    app = QtGui.QApplication.instance()
    if app is None:
        app = QtGui.QApplication([])
    # set app icon for tray:
    pyDir = os.path.dirname(os.path.abspath(__file__)) #python file location
    iconDir = os.path.join(pyDir, 'icons')
    app_icon = QtGui.QIcon()
    app_icon.addFile(os.path.join(iconDir, '256x256.png'), QtCore.QSize(256,256))
    app.setWindowIcon(app_icon)
    #should be a one-liner here?? app.setWindowIconTitle, etc?
    w = MainWindow()
    sys.exit(app.exec_())
