有什么方法可以在C ++中强制回调

想象一下，我有一些网络类 CNetwork ，它有一些叫做的方法： makeNetworkRequest（int requestCode）。来自 makeNetworkRequest（int requestCode）的响应当然可以在一段时间后调用此函数。我想要的是，当响应到来时，执行这样的代码，例如：

Hi,

Imagine I have some networking class CNetwork which has some method called: makeNetworkRequest(int requestCode). The response from makeNetworkRequest(int requestCode) can of course come some time later this function was called. What I want is that, when that response arrives, to execute such code for example:

void myApp::function1()
{
CMyButton button;
button.SetText(responseFromServer.text);
button.SetTextColor(responseFromServer.color);
}

我现在想要的是来自UI的用户可能正在使用不同的请求代码调用makeNetworkRequest - 以及基于此我可能想要执行不同的功能，例如执行function2而不是function1 - 我希望能够实现上面提到的功能。

The thing I want now is that the user from UI may be calling makeNetworkRequest with different request codes -- and based on that I may want to execute different functionality, e.g., for example execute function2 instead of function1 -- and I want to be able to achieve the functionality I mentioned above.

void myApp::function2()
{
CMyEdit edit;
edit.SetText(responseFromServer.text);
}
