如何在单击鼠标并按住某个键时触发事件？(How to trigger event when mouse is clicked AND a key is held down?)

在glutMouseFunc内部有没有办法检测键是否被按下？

Is there any way to detect if a key is being held down while inside of the glutMouseFunc?

最满意答案

是。 存储全局可访问的列表，列出当前按下的键。 然后在MouseFunc中读取该列表。

请注意，鼠标回调已经获得控制键状态（shift / alt / ctrl），因此您通常不需要这样做。

Yes. Store a globally-accessible list of what keys are currently held down. Then read that list in your MouseFunc.

Note that the mouse callback already gets the control key state (shift/alt/ctrl), so you generally don't need to do this.
