"to register" 在编程方面是什么意思?

What does "to register" mean in terms of programming?

我熟悉处理器寄存器,但我对这本编程电子书的作者如何使用这个词感到有点困惑:

"When you opened this e-book, it was the result of computations within the system which allowed you to launch the application, click the e-book have it register when you clicked the ebook, turn the pages, and so on."

现在,我一直怀疑这与处理器寄存器或 windows 注册表有关。

register 在这种情况下指的是捕获单击按钮的 action,之后可以执行其他代码。它与处理器寄存器或 windows 注册表无关。
