在 C++ 中进行事件处理的正确方法是什么?

问题描述

我有一个应用程序需要以下列方式响应某些事件:

I have an application that needs to respond to certain events in the following manner:

void someMethodWithinSomeClass() {
    while (true) {
        wait for event;
        if (event == SomeEvent) {
            doSomething();
            continue;
        }
        if (event == SomeOtherEvent) {
            doSomethingElse();
            continue;
        }
    } 
}

这将是一些线程运行.在其他一些线程中，操作将创建和触发事件.

This would be running is some thread. In some other threads, operations would create and fire the Events.

如何让这些事件到达上述方法/类?在 C++ 中实现事件处理的正确策略或架构是什么?

How do I get these Events to reach the above method/class? What is the proper strategy or architecture for implementing event handling in C++?

推荐答案

C++ 标准根本不处理事件.但是，通常情况下，如果您需要事件，您将在提供它们的框架内工作 (SDL、Windows、Qt、GNOME 等)以及等待、调度和使用它们的方法.

The C++ Standard doesn't address events at all. Usually, however, if you need events you are working within a framework that provides them (SDL, Windows, Qt, GNOME, etc.) and ways to wait for, dispatch and use them.

除此之外，您可能还想查看 Boost.Signals2.

Aside from that, you may want to look at Boost.Signals2.
