是否可以重新启动PyQt应用程序QApplication

Is there a way to restart PyQt application QApplication

我有一个使用以下代码使用pyqt4和python 2.6创建的应用

I have an app created with pyqt4 and python 2.6 using below code

app = QtGui.QApplication(sys.argv)

我有一些设置选项，可以在其中进行一些设置.现在，当我保存设置时，我需要重新加载应用程序，以便新设置生效.无需最终用户退出并再次启动应用程序.

i have settings options where i set some settings. Now when i save settings i need to reload the application so that new settings are effected. Without the need of end user to exit and launch the app again.

推荐答案

我有一个类似的问题，只是在适当的地方使用了它:

I had a similar problem and simply used this at the appropriate place:

subprocess.Popen([__file__])
sys.exit(0)

这是一个简单的应用程序，不需要任何其他参数.

It was a simple application, and didn't need any further arguments.
