X11 has two mechanism to report scroll events. The old-fashioned way is to treat the scroll wheel as two extra mouse buttons: scroll up is reported as button 4 and scroll down as button 5 (or vice versa, I don't remember). The modern way is to report them via the XInput2 extension, which allows things like horizontal scrolling and smooth scroll and suchlike.
X11有两种机制来报告滚动事件。传统的方法是将滚动轮视为两个额外的鼠标按钮:向上滚动被报告为按钮4，向下滚动为按钮5(或者相反，我不记得了)。现代的方法是通过XInput2扩展来报告它们，它允许水平滚动、平滑滚动等等。
