问题描述
有人可以告诉我有关检测和使用鼠标按钮的信息吗？我在MSDN文档中找到的所有内容都是你使用e.Delta，但它没有在
中解释如何。我尝试在frm.MouseDown中检测到滚轮的滚动，但是它没有检测到它。
感谢您的帮助。 />
Hi,
Can someone lead me to info on detecting and using the mouse button? All I
can find in the MSDN docs is that you use e.Delta, but it doesn''t explain in
how. I tried detecting the roll of the wheel in the frm.MouseDown, but it
didn''t detect it.
Thank for the help.

Mousedown is raised when a mouse button gets pressed, not when the wheel has
been turned.

e。 delta返回车轮转动的量。你在OnMouseWheel或MouseWheel事件中得到了''e'。
e.delta returns the amount the wheel has been turned. You get ''e'' in
OnMouseWheel or the MouseWheel event.
按下鼠标按钮时会引发Mousedown，而不是当转动
