有没有用于检测USB事件（插入和删除）的Qt解决方案？ [英] Is there a Qt solution for detecting USB events (insertion and removal)?

问题描述

由于其他人在几年前已经问过，我想在Pendrive / datatraveler插入时，以及在我的系统中（在Linux Ubuntu和Embedded Linux中）拔掉电源时，都可以在Qt应用程序中进行检测。

As some other people already asked here some years ago, I want to be able to detect in a Qt application when a pendrive/datatraveler is plugged and when it is unplugged in my system (both in Linux Ubuntu and Embedded Linux).

我在SO中搜索，我注意到大多数答案不仅非常过时（例如从2010年），但所有解决方案以某种方式涉及非Qt解决方案问题：平台特定或使用外部库，如udev和DBus。

I searched in SO and I noticed that most answers not only were very outdated (from 2010 for example), but all solutions somehow involved "non-Qt solutions" to these problem: either platform specific or usage of external libraries such as udev and DBus.

我想知道的首先是如果有一个特定的Qt解决方案，即一个这样做，而不需要添加外部libs或平台特定的代码，如何使用它。优先地，它应该已经在Qt 4.8。如果没有Qt解决方案，则可以接受基于Qt的库。

What I want to know first of all is if there is a specific Qt solution for this, i.e. a way to do this without requiring adding external libs or platform specific codes, and how could I use it. Preferentially it should already be available in Qt 4.8. If there is no Qt solution, then a Qt-based library would be acceptable.

推荐答案

如前所述， Qt 模块。然而，有一个用户创建的类<​​code> QDeviceWatcher 。

As already pointed out, Qt itself does not provide such a module. There is however a user-made class called QDeviceWatcher. I have no experience with it personally and it is not updated regularly but you could give it a try.
