QT4：如何重新启动应用程序？重新设置？ [英] QT4: How to restart application? Reset settings?

问题描述

1。）我想重新启动我的QT4应用程序。只是一个正常的关机和启动相同的应用程序。

1.) I would like to restart my QT4 application. Just a normal shutdown and start of the same application.

2）为什么？我需要一个选项来重置一切。重新启动应用程序似乎是最简单的方法来做到这一点。问题是，有很多类和一切。我没有时间把他们的每一个设置回到标准，每个textBox，Widget清除...我知道应用程序重新启动不是最好的方法，你认为有什么另一种方式？

2.) Why? Well i need an Option to "reset" everything. To restart the application seems to be the easiest way to do this. The problem is, that there are a LOT of classes and everything. I dont have the time to put every setting of them back to standard, every textBox, Widget to clear... I Know application restart is not the best way, what do you think is there another way?

谢谢

推荐答案

对于重新启动应用程序，您可以使用 startDetached 退出过程后：

For restarting an application you can use startDetached after quiting the process:

#include <QApplication>
#include <QProcess>

...

// restart the app:
qApp->quit();
QProcess::startDetached(qApp->arguments()[0], qApp->arguments());
