在C ++中执行事件处理的正确方法是什么？ [英] What is the proper way of doing event handling in C++?

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;
        }
    } 
}

这将运行是一些线。在其他线程中，操作将创建并触发事件。如何让这些事件达到上述方法/类？在C ++中实现事件处理的恰当策略或架构是什么？

This would be running is some thread. In some other threads, operations would create and fire the Events. 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 ++标准根本不涉及事件。但是，通常情况下，如果您需要事件，您可以在提供它们的框架中工作（ 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，您可能需要查看 Boost.Signals2 。

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